Build a Weather Impact Report Pipeline with n8n

Automating weather impact reporting is critical for organizations that depend on timely, accurate situational awareness. With n8n and modern language model tooling, you can implement a fully automated pipeline that ingests weather alerts, enriches them with semantic context, generates human-readable impact summaries, and logs everything for later analysis.

This article explains how to build a production-grade Weather Impact Report pipeline using n8n, LangChain-style components (text splitter, embeddings, vector store), Supabase with pgvector, Hugging Face embeddings, Anthropic chat, and Google Sheets. The focus is on architecture, key nodes, and best practices suitable for automation and data engineering professionals.

Business case for automating weather impact reports

Weather conditions directly influence supply chains, field operations, logistics, public events, and customer safety. Many teams still rely on manual workflows to collect alerts, interpret potential impacts, and communicate recommendations. These manual processes are slow, difficult to audit, and prone to inconsistency.

An automated n8n workflow can:

• Ingest weather updates from multiple sources through webhooks or APIs
• Use language models to summarize and interpret operational impact
• Store semantic embeddings for efficient retrieval and context reuse
• Maintain a structured, searchable audit trail in systems like Google Sheets

The result is a repeatable, observable pipeline that converts raw weather data into actionable intelligence with minimal human intervention.

High-level architecture of the n8n workflow

The Weather Impact Report pipeline uses a modular design that separates ingestion, enrichment, retrieval, and reporting. At a high level, the workflow includes:

• Webhook (n8n) – entrypoint for POST events from weather feeds or ingestion services
• Text Splitter – segments long advisories into manageable chunks for embedding
• Embeddings (Hugging Face) – converts each text chunk into a semantic vector
• Vector Store (Supabase + pgvector) – persistent storage and similarity search over embeddings
• Tool / Query node – wraps the vector store as a retriever for LLM-based workflows
• Memory and Chat (Anthropic) – maintains conversational context and generates the final impact summary
• Agent with Google Sheets integration – orchestrates the response and writes a structured log entry

This architecture is extensible. You can plug in additional alerting channels, observability, or downstream systems without changing the core pattern.

Data ingestion: capturing weather events

1. Webhook node configuration

The workflow starts with an n8n Webhook node configured to accept POST requests. This endpoint is typically called by your weather provider, an internal integration service, or a scheduled polling script.

A representative JSON payload might look like:

{  "source": "NOAA",  "event": "Heavy Snow Warning",  "timestamp": "2025-01-28T06:30:00Z",  "text": "Heavy snow expected across County A, travel strongly discouraged..."
}

Security considerations at this layer are essential:

• Protect the webhook with a secret token or signature validation
• Restrict inbound traffic using IP allowlists or a gateway
• Use n8n credentials management for any downstream API secrets

Once the payload is received, it flows into the processing segment for text preparation and embedding.

Preparing text for semantic processing

2. Splitting long advisories into chunks

Operational weather bulletins can be lengthy and often exceed typical token limits for embedding models or chat models. To handle this, the workflow uses a Splitter node that breaks the input text into smaller, overlapping segments.

A typical configuration might be:

• chunkSize = 400 characters (or tokens, depending on implementation)
• overlap = 40 to preserve context across boundaries

This approach keeps each chunk within model limits while maintaining local continuity, which improves the quality of semantic embeddings and downstream retrieval.

3. Generating embeddings with Hugging Face

Each text chunk is then passed to an Embeddings node configured with a Hugging Face embeddings model. The node converts text into high-dimensional numeric vectors that capture semantic meaning.

Recommendations:

• Select a sentence-transformer style model that balances accuracy, latency, and cost
• Standardize preprocessing (case normalization, whitespace handling) for consistent embeddings
• Consider caching embeddings for identical or repeated texts to reduce cost

The output of this stage is a set of vectors, each associated with its original text chunk and metadata from the incoming payload.

Persisting and retrieving context with Supabase

4. Inserting vectors into a Supabase vector store

To support long-term retrieval and contextualization, the workflow writes embeddings into a Supabase table backed by Postgres and pgvector. Each record typically includes:

• The embedding vector itself
• Source system (for example NOAA)
• Event type (for example Flood Advisory, Heavy Snow Warning)
• Timestamp of the original event
• Optional geospatial or region identifiers
• The raw text snippet for reference

Supabase provides a convenient managed environment for Postgres plus vector search, which keeps operational overhead low while enabling efficient similarity queries.

5. Querying the vector index with a Tool node

When generating a new report or answering a query about current or historical conditions, the workflow needs to retrieve relevant past information. This is handled by:

• A Query node that runs a similarity search against the pgvector index
• A Tool node that exposes this query capability as a retriever to the Agent or Chat node

Key configuration parameters include:

• Similarity threshold to control how close matches must be
• Maximum number of results to return for each query
• Optional filters on metadata (for example source, event type, region, time window)

This retrieval step ensures that the language model has access to relevant historical context and related advisories when composing impact reports.

LLM orchestration: memory, chat, and agent logic

6. Memory and Anthropic Chat nodes

To maintain continuity across multiple interactions and reports, the workflow employs a Memory node. This node stores recent conversations or prior generated reports so that the model can reason over ongoing conditions.

The Chat node, configured with an Anthropic model, receives:

• The current weather payload and key metadata
• Relevant chunks retrieved from the vector store
• Any stored context from the Memory node

From this combined context, the Anthropic model generates a structured, human-readable weather impact summary. Typical outputs include:

• Overall situation summary
• Operational risks and potential disruptions
• Impacted regions or assets
• Recommended mitigation or response actions

Anthropic models are used here to prioritize controlled, high-quality outputs and safer behavior, which is important in risk-sensitive domains like weather-related operations.

7. Agent orchestration and Google Sheets logging

The Agent node coordinates the final stage of the workflow. It parses the Chat node response and maps it to a structured record that can be logged and consumed by downstream systems.

A typical schema for the log entry might include:

• Report headline or title
• Severity level inferred or mapped from the event
• Affected areas or regions
• Summary of expected impact
• Recommended actions
• Source, event type, and timestamp

The Agent then uses a Google Sheets node to append this data as a new row in a designated sheet. This provides:

• An easily accessible dashboard for stakeholders
• A durable audit trail of all generated reports
• A simple dataset for later analytics or quality review

Illustrative payload and end-to-end flow

The following example shows a more detailed JSON payload flowing through the pipeline:

{  "source": "NOAA",  "event": "Flood Advisory",  "severity": "Moderate",  "areas": ["County A", "County B"],  "text": "Heavy rainfall expected - potential flooding on low-lying roads...",  "timestamp": "2025-01-28T06:30:00Z"
}

Processing steps:

1. The webhook receives the payload and passes the text field to the Splitter.
2. Chunks are generated, embedded via Hugging Face, and inserted into the Supabase vector table with metadata like severity and areas.
3. When the Agent constructs a report, it queries the vector store to retrieve semantically similar events, possibly filtered to the same areas or severity range.
4. The Anthropic Chat node uses both the current advisory and retrieved history to generate a nuanced impact report.
5. The Agent writes a structured summary into Google Sheets as a new log entry.

Implementation best practices and optimization tips

Metadata and schema design

• Always store rich metadata with vectors, including source, event type, timestamp, geolocation, severity, and region identifiers.
• Design your Supabase table schema with clear indexes on frequently filtered fields such as timestamp and region.
• Use consistent naming and typing for fields so that filters and queries remain predictable.

Chunking and embedding strategy

• Tune chunkSize and overlap based on your dominant document type:
  • Short alerts or advisories may require smaller chunks.
  • Long technical bulletins or multi-part reports may benefit from larger chunks.
• Normalize text prior to embedding to avoid unnecessary vector duplication.
• Deduplicate identical content before sending it to the embedding model for cost control.

Performance, throttling, and cost control

• Implement rate limiting or backoff strategies in n8n to stay within external API quotas for Hugging Face and Anthropic.
• Batch embeddings and Supabase inserts where possible to improve throughput.
• Use a lower-cost embedding model for broad similarity search and, if needed, a more expensive model for high-precision scenarios.

Security and compliance

• Store all API keys and credentials using n8n’s secure credential management.
• Enable row-level security in Supabase where appropriate, especially if multiple teams or tenants share the same database.
• Secure the webhook endpoint with authentication and network controls.

Testing, validation, and quality assurance

Before promoting the workflow to production, validate each stage individually and then perform end-to-end tests.

Node-level testing

• Simulate webhook payloads using representative JSON samples.
• Verify that the Splitter is producing chunks of the expected size and overlap.
• Inspect embeddings and Supabase inserts to confirm schema correctness and metadata presence.

End-to-end validation

1. Send a synthetic or historical weather event to the webhook.
2. Confirm that all chunks are embedded and stored in Supabase with correct metadata.
3. Run a contextual query and manually inspect the retrieved snippets for relevance.
4. Review the Anthropic Chat node output to ensure it is clear, actionable, and aligned with your operational guidelines.
5. Check the Google Sheet for the appended row and validate field mappings and data consistency.

Scaling, monitoring, and observability

As event volume grows, you will need to ensure that the pipeline remains performant and observable.

• Batching: Group embeddings and database writes to reduce overhead and improve throughput.
• Partitioning: Partition Supabase vector tables by date or region to narrow the search space for common queries.
• Metrics: Track key metrics such as:
  • Ingestion rate (events per minute or hour)
  • Average embedding time per chunk
  • Vector query latency and result counts
  • Agent or Chat node failures and timeouts
• Observability stack: Export metrics and logs to systems such as Prometheus, Grafana, or Datadog for centralized monitoring.

Advanced extensions and enhancements

Once the core pipeline is stable, you can extend it with more advanced capabilities:

• Geospatial filtering: Combine vector similarity with geospatial queries so that retrieval is limited to nearby or jurisdiction-specific impacts.
• Alerting and incident management: Route high-severity or time-critical reports to Slack, SMS, or an incident management platform.
• Feedback loop: Allow operators to rate generated reports as accurate or inaccurate, then store that feedback as additional metadata for future evaluation or fine-tuning workflows.
• Multi-source data fusion: Ingest additional feeds such as radar, satellite imagery summaries, or social media signals to provide richer context to the Chat node.

Conclusion and next steps

Using n8n together with LangChain-style components, Supabase, Hugging Face embeddings, and Anthropic models, you can implement a complete Weather Impact Report pipeline that is flexible, auditable, and ready for production workloads.

A pragmatic rollout approach is:

1. Implement the webhook and text splitting stages.
2. Add embeddings and Supabase vector storage for retrieval.
3. Integrate the Anthropic Chat node and Memory for contextual impact summaries.
4. Finalize logging and reporting with the Agent and Google Sheets.

Once the core flow is working, refine chunking, retrieval parameters, and prompts to align with your operational standards.

Call to action: If you would like a tailored n8n workflow JSON that matches your weather data schema, preferred Hugging Face model, and Supabase table design, share your data format and expected traffic volume and I can draft a customized configuration for you.

AI Logo-Sheet Extractor to Airtable – Automate Logo Intelligence with n8n

Converting dense logo sheets into a structured, queryable dataset is a classic low-value, high-effort task. This guide presents a production-ready n8n workflow template that uses AI vision and language models to interpret a logo-sheet image, extract tools and attributes, and synchronize the results with Airtable. The article explains the architecture, node responsibilities, Airtable schema design, prompt strategy, and operational best practices so you can implement a reliable “upload-and-forget” automation in your own environment.

Use case and value proposition

This workflow is designed for teams that routinely handle visual catalogs of products or vendors and need to operationalize that information. Typical scenarios include:

• Mapping competitive landscapes from conference slides or analyst reports
• Building and maintaining a product taxonomy or AI tools catalog
• Capturing vendor ecosystems from marketing one-pagers or pitch decks

Instead of manual transcription, the workflow uses an AI agent to interpret a single logo-sheet image and then normalizes, deduplicates, and links that data into Airtable. It is optimized for repeatability and can support scheduled imports as well as on-demand uploads from internal stakeholders.

Solution architecture

The automation is implemented as an n8n workflow that coordinates three primary components:

• n8n workflow engine – orchestrates triggers, AI calls, data transformations, and Airtable operations.
• AI Vision + LLM agent – analyzes the uploaded image, identifies tools or brands, and outputs structured JSON with attributes and competitor suggestions.
• Airtable – acts as the system of record for tools and attributes, using deterministic hashes and record IDs for reliable upserts and relationships.

Logical flow overview

At a high level, the workflow performs the following steps:

• Accepts a logo-sheet image through a form-based trigger.
• Prepares and sends the image plus contextual prompt to an AI vision + LLM agent.
• Parses the agent’s structured output into per-tool and per-attribute items.
• Upserts attributes into Airtable and retrieves their record IDs.
• Upserts tools into Airtable, including relationships to attributes and similar tools.
• Ensures competitor mappings are persisted as linked records in Airtable.

Key n8n node groups and responsibilities

Trigger and input handling

• FormTrigger (On form submission) Receives the uploaded logo-sheet image and an optional text prompt from a public or internal web form. The image should be high enough resolution to capture smaller logos but still within your file size limits. The prompt can include context such as: “This sheet compares enterprise AI infrastructure tools.”
• Map Agent Input Normalizes the form input into a payload suitable for the AI agent. This node is the right place to inject additional hints like expected industries, categories, or naming conventions to improve extraction accuracy.

AI interpretation and structured output

• Retrieve and Parser Agent (AI Vision + LLM) This node is the core of the workflow. It uses a vision-enabled LLM to inspect the image and return a JSON structure containing all detected tools. Each tool includes a name, a list of attributes, and a list of similar or competitor tools. A structured-output parser schema is used to enforce consistent JSON formatting and field names.

The expected JSON structure resembles the following:

{  "tools": [{  "name": "ToolName",  "attributes": ["Category","Feature","Platform"],  "similar": ["CompetitorA","CompetitorB"]  }]
}

Prompt design tip: instruct the agent to be conservative and list only logos it can clearly identify. Ask for short, standardized attribute labels, for example “Agentic Application” or “Browser Infrastructure”, to improve downstream deduplication in Airtable.

Data normalization and splitting

• Split & Normalize After the agent returns the JSON payload, this node (or group of nodes) splits the tools array into individual items so that each tool can be processed independently. It also extracts and normalizes attribute strings into separate items for batch checking and creation in Airtable. This structure enables parallel operations and deterministic mapping back to each originating tool.

Airtable integration and upsert logic

• Attributes upsert (Airtable) For every unique attribute string, the workflow checks the Airtable Attributes table and performs an upsert. At minimum, the table should include a Name field and a linked Tools field. The node returns the Airtable record ID (RecID) for each attribute, which is then used to replace raw attribute names with stable record links.
• Tools upsert (Airtable) Before creating or updating tools, the workflow generates a deterministic hash for each tool name, for example an MD5 hash of the normalized name. This hash is used as a stable key to detect existing tools and avoid duplicates caused by casing or whitespace differences. The Tools table is then upserted with:
  • Name
  • Attributes (linked attribute RecIDs)
  • Similar (linked tool RecIDs)
  • Hash (used for matching)
• Map Similar relationships When the AI output includes similar or competitor names, the workflow ensures that each referenced tool exists in Airtable (creating records if needed) and then links their RecIDs into the Similar field of the origin tool. Depending on your usage pattern, you can maintain these as unidirectional or manage bidirectional links through Airtable views or additional automations.

Recommended Airtable schema

For maintainability, keep the schema minimal yet fully relational. A typical configuration includes two primary tables.

Tools table

• Name – single line text, required
• Attributes – linked records to Attributes table, multiple allowed
• Similar – linked records to Tools table, multiple allowed
• Hash – single line text used for deterministic matching and upsert
• Optional fields – for enrichment, such as:
  • Description
  • Website
  • Category (multi-select)

Attributes table

• Name – single line text, required
• Tools – linked records back to Tools table, typically managed automatically by Airtable when relationships are created

Prompt strategy and accuracy best practices

Prompt quality has a direct impact on the consistency and reliability of your Airtable data. Consider the following guidelines:

• Provide domain context Indicate the domain or vertical in the prompt, for example “enterprise AI applications”, “developer tooling”, or “marketing technology”. This helps the model interpret ambiguous brand names correctly.
• Request conservative extraction Ask the agent to only output tools and attributes it is confident about. This reduces hallucinations and spurious entries.
• Standardize attribute labels Instruct the model to generate short, consistent attribute names, ideally in a normalized format that aligns with your existing taxonomy.
• Improve image quality where needed For sheets with many small or low-contrast logos, provide a higher-resolution image or crop the sheet into segments and run the workflow multiple times.

Handling edge cases and data quality

For production use, it is important to manage failure modes and ambiguity explicitly. Some recommended patterns include:

• False positives If the agent tends to invent tool names, introduce a second validation step that checks extracted names against an allowlist or a curated reference database.
• Partial or ambiguous matches Use fuzzy matching or a human-in-the-loop review process for low-confidence items. n8n can route uncertain cases to a review queue or a notification channel.
• Duplicate attributes Normalize attribute strings before upsert, for example by trimming whitespace and lowercasing, and optionally maintain a canonical attribute mapping table for further consolidation.
• Incomplete similar relationships Periodically run reconciliation jobs that infer additional competitor links from multiple logo sheets or from other data sources.

Security, privacy, and governance

If the logo sheets include internal, confidential, or regulated information, align the implementation with your organization’s data policies:

• Use AI providers that meet your compliance requirements.
• Restrict access to the form trigger, Airtable base, and API keys.
• Store credentials securely within n8n and rotate tokens regularly.
• Monitor workflow executions and API usage for anomalies.

Scaling and performance considerations

When processing large volumes of logo sheets or very large images, consider the following optimization strategies:

• Rate limiting Airtable writes Batch records where possible and introduce short delays between write operations to stay within Airtable’s rate limits.
• Controlled parallelism Parallelize agent calls for multiple images but cap concurrency in n8n to avoid throttling from AI and Airtable APIs.
• Caching attribute mappings Cache known attribute-to-RecID mappings in memory or in a lightweight datastore to reduce repeated Airtable lookups and improve throughput.

Debugging and operational checklist

When troubleshooting or hardening the workflow, use this checklist:

• Verify that the AI agent returns valid, well-formed JSON that matches the expected schema. Use the structured output parser to enforce this.
• Ensure attribute normalization (trimming, casing) occurs before matching or upserting into Airtable to prevent silent duplication.
• Inspect Airtable API responses for rate limit, authentication, or permission errors.
• Review n8n execution history to trace payload transformations and identify where unexpected values are introduced.

Example AI output

The following is a representative example of the structured JSON the agent might produce for a logo sheet:

{  "tools": [  {  "name": "Pinecone",  "attributes": ["Storage Tool","Memory management"],  "similar": ["Chroma","Weaviate"]  },  {  "name": "LangGraph",  "attributes": ["Framework Tool","Graph Management"],  "similar": ["LlamaIndex","Semantic Kernel"]  }  ]
}

This output is then normalized and translated into Airtable records with linked attributes and similar tools as described above.

Extending and customizing the workflow

Once the core pipeline is in place, it is straightforward to extend the workflow for additional business needs:

• Add a secondary validation agent that cross-checks tool names against a domain-specific catalog or internal system.
• Build Airtable dashboards and views to visualize categories, clusters, and competitor networks.
• Integrate Slack or email notifications to alert teams when new tools are discovered or when an extraction run fails.

Conclusion and implementation next steps

This n8n workflow template turns static logo sheets into structured, relational data in Airtable with minimal manual effort. It is particularly valuable for teams building product taxonomies, tracking competitive landscapes, or maintaining up-to-date AI tooling inventories.

To adopt the automation in your environment:

1. Import or recreate the n8n workflow in your instance.
2. Connect your Airtable credentials and configure the recommended schema.
3. Adjust the AI prompt to reflect your domain, naming conventions, and quality thresholds.
4. Test with a high-resolution sample logo sheet and review the resulting Airtable records.

Ready to automate your logo sheets into Airtable? Deploy the template, connect your data sources, and start converting visual logo collections into searchable, linked records. If you need to adapt the prompt, schema, or matching logic for your specific industry or scale requirements, refine the workflow nodes accordingly.

Pro tip: For very dense logo sheets, run the workflow multiple times with different crops or slightly varied prompts and then aggregate the results in Airtable to improve overall coverage.

n8n + E-goi: Create, Update & Get a Subscriber

Picture this: you are copying the same email, first name, and list ID into E-goi for the hundredth time, wondering if this is really what your life has become. Good news – it does not have to be. With an n8n workflow and the E-goi node, you can make the robots do the boring stuff while you pretend it was all part of your grand strategy.

In this guide, we will walk through an n8n workflow template that handles three classic E-goi subscriber operations for you:

• Create a new subscriber
• Update that subscriber
• Get the final contact details back out of E-goi

You will see how the nodes connect, how to configure each step, and how to use n8n expressions so data flows smoothly from one node to the next. This is useful whether you are a marketer trying to keep your lists clean or a developer who refuses to touch a manual export ever again.

Why automate E-goi subscriber management with n8n?

Manually managing subscribers is like doing data entry as a hobby. Automation is the opposite: it quietly handles the repetitive bits while you focus on campaigns, strategy, or literally anything else.

Using n8n with the E-goi node lets you:

• Create new contacts automatically when someone signs up, fills a form, or appears in another system.
• Update contact fields based on rules you define, like changing names, tags, or custom fields.
• Retrieve contact details and pass them to the rest of your workflow, your CRM, or your reporting tools.

The result is synced contact data across CRMs, landing pages, sign-up forms, and whatever other tools you have glued together.

What this n8n + E-goi workflow template actually does

The template is a compact four-node workflow that looks simple on the outside but saves you from a lot of repetitive clicking:

• Manual Trigger – lets you run the workflow on demand while you test or debug.
• E-goi (create contact) – creates a new subscriber in a specific E-goi list.
• E-goi1 (update contact) – updates that same subscriber with new data.
• E-goi2 (get contact) – retrieves the final version of the contact so you can verify or use it downstream.

The workflow starts with a simple JSON payload that defines the subscriber you want to create:

{  "list": 1,  "email": "nathan@testmail.com",  "additionalFields": {"first_name": "Nathan"}
}

This object is used in the first E-goi node to create the contact. E-goi then returns a response that includes a contact_id. That contact_id is the star of the show, because the next nodes grab it via expressions and use it to update and fetch the same subscriber.

Node-by-node tour of the workflow

1. Manual Trigger – your testing remote control

The Manual Trigger node is simply there so you can run the workflow on demand while building and testing it. You click “Execute workflow,” it fires, and you see what happens.

Once everything works and you are ready for real automation, you can replace this with a:

• Webhook trigger for real-time sign-ups
• Schedule trigger for regular syncs
• Any other trigger that fits your use case

2. E-goi (create contact) – adding a new subscriber

This node creates your new E-goi subscriber. It uses three main parameters:

• list – the ID of the E-goi list where the contact should be added, for example 1.
• email – the email address of the subscriber you want to create.
• additionalFields – extra attributes like first name, last name, phone number, and other custom fields.

The sample configuration in the template looks like this:

list: 1
email: nathan@testmail.com
additionalFields: { first_name: "Nathan" }

When this node runs, E-goi returns a response object that includes contact_id under json.base.contact_id. That value is crucial because the following nodes use it to identify which subscriber to update and fetch.

3. E-goi1 (update contact) – changing subscriber details

Next comes the E-goi1 node, which performs the update operation. Instead of hard-coding IDs, it uses n8n expressions to pull data from the previous E-goi node. That way, the workflow adapts to whatever contact was just created.

The important parameters in the template are:

list: ={{$node["e-goi"].parameter["list"]}}
contactId: ={{$node["e-goi"].json["base"]["contact_id"]}}
operation: update
updateFields: { first_name: "Nat" }

Here is what is going on:

• {{$node["e-goi"].parameter["list"]}} reuses the exact same list ID that you configured in the create node.
• {{$node["e-goi"].json["base"]["contact_id"]}} reads the contact_id returned from the create operation response.

In this example, the subscriber’s first name is being updated from Nathan to Nat. You can extend updateFields with any other fields supported by your E-goi setup.

4. E-goi2 (get contact) – verifying the final result

The last node, E-goi2, retrieves the updated contact so you can confirm everything worked or send the data elsewhere.

Its configuration uses expressions again:

list: ={{$node["e-goi"].parameter["list"]}}
contactId: ={{$node["e-goi1"].json["base"]["contact_id"]}}
operation: get

This node:

• Reads the list ID from the first E-goi node.
• Uses the contact_id from the update node response.

After this “get” operation, you have the definitive contact object. From here, you can:

• Log it for debugging
• Send it to another tool or database
• Trigger additional automations based on the contact’s data

How to set up and run the template in n8n

Ready to trade your copy-paste habit for automation? Here is the simplified setup guide.

1. Import the workflow JSON
   Open your n8n instance, go to the editor, and import the provided workflow JSON file.
2. Set up E-goi credentials
   In n8n, add your E-goi API key and account details in the credentials section so the E-goi nodes can authenticate.
3. Adjust the create contact node
   Open the first E-goi node and update:
   • list to match the correct list ID in your E-goi account
   • email with a test email or dynamic value
   • additionalFields with the fields you want to store, like first_name or others
4. Confirm the expressions in update and get nodes
   Check that the expressions in the update and get nodes still reference the right node names, such as e-goi and e-goi1. If you rename nodes, update the expressions accordingly.
5. Run the workflow with the Manual Trigger
   Execute the workflow. Inspect the output of each node to verify:
   • The contact is created successfully
   • The update applies correctly
   • The final get operation returns the expected contact data

Troubleshooting when things get grumpy

Sometimes APIs wake up on the wrong side of the server. If your workflow misbehaves, start with these checks:

• Invalid credentials
  If requests fail or you see authentication errors, double-check your E-goi API key in n8n credentials and confirm that your E-goi account has API access enabled.
• Missing contact_id in the response
  Make sure the create contact operation actually succeeds. Look at the raw JSON response from the first E-goi node. The template expects contact_id at json.base.contact_id. If E-goi’s response structure is different in your account or version, adjust the expression path accordingly.
• List ID errors
  If E-goi complains about the list, confirm that the list ID you are using really exists in your E-goi account and that your credentials have access to it.
• Rate limits
  Running many executions in a short time can trigger E-goi rate limits. If that happens, add some rate limiting or retry logic so your workflow is more polite.
• Expression errors
  If you rename a node and forget to update expressions, n8n will not find the referenced node. Update any expressions like {{$node["e-goi"].json[...]}} to match the new node names.

Best practices to level up your n8n + E-goi workflow

Once the basic template works, you can start improving it so it behaves more like a reliable teammate and less like a fragile demo.

• Use a webhook trigger for real-time sign-ups
  Replace the Manual Trigger with a Webhook node to capture sign-ups from forms or landing pages instantly.
• Add error handling
  Use n8n’s Error Workflow or extra Function nodes to catch failed requests, log errors, and send notifications when something breaks.
• Clean up data before sending it
  Normalize fields in n8n first. For example, trim whitespace, validate email formats, or standardize name casing.
• Use conditional updates
  Add an IF node so you only call the update operation when values have actually changed. That keeps your API usage lean.
• Store the contact_id in your own systems
  Save the returned contact_id in your database or CRM. That way, you can reference the E-goi contact later without extra lookup calls.

Adding simple retry logic for reliability

APIs occasionally time out, just to keep everyone humble. To make your workflow more resilient, you can introduce a basic retry pattern.

One approach is to combine a Function node, a Delay node, or n8n’s built-in retry options. A simple pseudo-flow might look like:

1. Create contact node → on failure → Delay (5 seconds) → retry create contact (up to 3 attempts)
2. If it still fails after retries, send an error notification via Slack or email so a human can investigate.

This small addition can save you from silent failures when E-goi is having a temporary hiccup.

Where this template really shines: use cases

This workflow is a great starting point for many automation scenarios that touch E-goi subscribers, such as:

• Syncing newsletter signups from a landing page or form directly into an E-goi list.
• Keeping CRM and E-goi in sync by mirroring contact properties and custom fields between systems.
• Enriching contact data from other services (for example, enrichment APIs or internal tools) and then updating E-goi with the latest information.

Wrapping up: a simple template with real impact

This n8n template gives you a clear, repeatable pattern for working with E-goi subscribers:

• Create a contact
• Update that contact
• Fetch the final contact record

By using expressions to pass the contact_id and list ID between nodes, the workflow stays flexible and robust, even as you customize it for your own data model and logic.

Once you are comfortable with the basics, you can extend the workflow with different triggers, more fields, better error handling, and additional integrations. The goal is simple: let automation handle the repetitive bits so you do not have to.

Next steps and call to action
