n8n Workflows with the Rodz API: Open-Source Intent Signal Automation

Peter Cools · · 15 min read

TL;DR: n8n is an open-source workflow automation platform you can self-host or run in the cloud. Paired with the Rodz API, it lets you capture intent signals in real time and route them anywhere: CRM records, Slack alerts, enrichment pipelines, databases. This guide walks you through the full setup, from installing n8n to building production-ready workflows that react to signals the moment they fire.

What is n8n?

n8n (pronounced “n-eight-n”) is a workflow automation tool similar to Zapier or Make, with one major difference: it is open-source under a fair-code license. You can run it on your own server, inspect every line of code, and extend it with custom nodes. It also offers a hosted cloud version if you prefer not to manage infrastructure.

For teams that care about data sovereignty, cost control at scale, or deep customization, n8n is a compelling choice. It supports over 400 integrations out of the box, has a visual workflow editor, and exposes a powerful JavaScript/Python code node for anything the built-in nodes cannot handle.

In the context of the Rodz API, n8n acts as the orchestration layer. Rodz detects intent signals (fundraising rounds, job postings, leadership changes, competitor moves) and n8n decides what happens next: create a deal in your CRM, notify a sales rep, enrich the company data, or all three at once.

Prerequisites

Before you start building, make sure you have the following ready:

  1. A Rodz account with API access. API access is available on all paid plans. Generate your API key from the Rodz dashboard under Settings > API Keys.
  2. A working n8n instance. Either self-hosted (Docker is the easiest path) or a cloud account at n8n.io.
  3. Basic familiarity with REST APIs. You should be comfortable reading JSON responses and setting HTTP headers. If you need a refresher, start with the Rodz API reference.
  4. A destination for your data. This could be HubSpot, Salesforce, Pipedrive, Slack, a Postgres database, or any tool that n8n can connect to.
  5. cURL or Postman (optional but helpful for testing API calls before wiring them into n8n).

If you have never made a call to the Rodz API before, work through the authentication and first request guide first. The rest of this article assumes you already have a valid API key and understand the basics of Bearer token authentication.

Step 1: Install and configure n8n

If you already have n8n running, skip to Step 2. Otherwise, the fastest way to get started is Docker.

Self-hosted with Docker

Create a directory for n8n data, then run a single command:

mkdir -p ~/.n8n
docker run -d \
  --name n8n \
  -p 5678:5678 \
  -v ~/.n8n:/home/node/.n8n \
  n8nio/n8n

Open http://localhost:5678 in your browser. You will see the n8n setup wizard. Create your admin account and you are ready to build workflows.

For production deployments, add a reverse proxy (Traefik, Nginx) with TLS, set N8N_PROTOCOL=https, and configure a proper WEBHOOK_URL environment variable so that external services can reach your n8n instance. This is critical for receiving Rodz webhooks.

n8n Cloud

Sign up at n8n.io, create a workspace, and you are ready. The cloud version handles TLS, uptime and updates for you. The webhook URL is provisioned automatically.

Step 2: Store your Rodz API key as a credential

Never hardcode API keys inside workflow nodes. n8n has a built-in credentials system that encrypts secrets at rest.

  1. In the n8n UI, go to Settings > Credentials.
  2. Click Add Credential and choose Header Auth.
  3. Set the header name to Authorization and the value to Bearer YOUR_API_KEY.
  4. Name the credential something descriptive, like “Rodz API - Production”.
  5. Save.

You will reference this credential in every HTTP Request node that talks to the Rodz API. If you rotate your API key later, you only need to update it in one place.

Step 3: Poll signals with the HTTP Request node

The simplest integration pattern is polling. You ask the Rodz API for new signals on a schedule, then process the results.

Create the workflow

  1. Open n8n and click New Workflow.
  2. Add a Schedule Trigger node. Set it to run every 5 minutes (or whatever frequency matches your use case and rate limits).
  3. Add an HTTP Request node after the trigger.

Configure the HTTP Request node

Set the following parameters:

  • Method: GET
  • URL: https://api.rodz.io/v1/signals
  • Authentication: Select the “Rodz API - Production” credential you created.
  • Query Parameters:
    • created_after: Use an expression to send only the timestamp of your last poll. A simple approach is {{ $now.minus(5, 'minutes').toISO() }} to fetch signals created in the last 5 minutes.
    • limit: 50 (adjust based on expected volume).
    • type: Filter by signal type if you only care about specific categories, for example fundraising or job_posting.

The response will be a JSON array of signal objects. Each signal contains the company name, signal type, metadata, and a timestamp.

Handle pagination

If your account generates a high volume of signals, the API uses cursor-based pagination. Check the response for a next_cursor field. If it exists, loop back and fetch the next page. In n8n, you can handle this with an IF node that checks for the cursor, feeding back into the HTTP Request node with the cursor query parameter set.

For a detailed explanation of pagination and rate limits, see the API reference guide.

Step 4: Receive signals in real time with webhooks

Polling works, but webhooks are better. Instead of asking the API every few minutes, the Rodz platform pushes signals to your n8n instance the moment they are detected.

Set up the webhook in n8n

  1. Add a Webhook node to a new workflow.
  2. Set the HTTP method to POST.
  3. Copy the webhook URL that n8n generates. It looks something like https://your-n8n-domain.com/webhook/abc123.
  4. Activate the workflow so the webhook endpoint is live.

Register the webhook with Rodz

Use the Rodz API to register your n8n webhook URL:

curl -X POST https://api.rodz.io/v1/webhooks \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://your-n8n-domain.com/webhook/abc123",
    "events": ["signal.created"],
    "active": true
  }'

You can subscribe to specific event types or receive all signals. For a full walkthrough of webhook configuration, event types and retry behavior, read the webhook setup guide.

Validate incoming webhooks

Rodz signs every webhook payload with a signature header. In n8n, add a Code node immediately after the Webhook node to verify the signature:

const crypto = require('crypto');

const secret = $env.RODZ_WEBHOOK_SECRET;
const signature = $input.first().headers['x-rodz-signature'];
const payload = JSON.stringify($input.first().json);

const expected = crypto.createHmac('sha256', secret).update(payload).digest('hex');

if (signature !== expected) {
  throw new Error('Invalid webhook signature');
}

return $input.all();

Store RODZ_WEBHOOK_SECRET as an n8n environment variable. This ensures that only legitimate payloads from Rodz are processed.

Step 5: Route signals to your CRM

Once signals are flowing into n8n (via polling or webhooks), the next step is routing them to the tools your team already uses.

Example: Create a HubSpot deal on fundraising signals

  1. After the HTTP Request or Webhook node, add a Switch node.
  2. Route based on the signal_type field. Create one output for fundraising, another for job_posting, and a fallback for everything else.
  3. On the fundraising output, add a HubSpot node.
  4. Set the operation to Create Deal.
  5. Map the signal fields to deal properties:
    • Deal name: {{ $json.company_name }} - Fundraising {{ $json.metadata.round }}
    • Amount: {{ $json.metadata.amount }}
    • Pipeline: Your outbound pipeline
    • Stage: “New Signal”

Example: Post to Slack on leadership changes

  1. On another Switch output (e.g., leadership_change), add a Slack node.
  2. Choose the channel where your sales team operates.
  3. Compose a message with the signal details:
New leadership change detected:
Company: {{ $json.company_name }}
Person: {{ $json.metadata.person_name }}
New role: {{ $json.metadata.new_title }}
Signal date: {{ $json.created_at }}

This gives your reps immediate, actionable context without logging into another dashboard.

Step 6: Enrich signals with additional data

Raw signals are useful. Enriched signals are powerful. The Rodz API also exposes enrichment endpoints that let you pull additional company and contact data.

After receiving a signal, add another HTTP Request node:

  • Method: POST
  • URL: https://api.rodz.io/v1/enrich/company
  • Body:
{
  "domain": "{{ $json.company_domain }}"
}

The enrichment response returns firmographic data: employee count, industry, revenue range, technologies used, social profiles. Merge this data with the original signal before pushing it to your CRM, so your sales reps have a complete picture without manual research.

You can chain multiple enrichment calls. For example, after enriching the company, use the contact enrichment endpoint to find decision-makers at that company and add them as contacts in your CRM.

Step 7: Add error handling and retries

Production workflows need to be resilient. n8n provides several mechanisms for this.

Retry on failure

On any HTTP Request node, enable Retry On Fail in the node settings. Set the number of retries to 3 and the wait between retries to 5,000 ms. This handles transient network issues and temporary API rate limits gracefully.

Error workflow

Create a dedicated error workflow in n8n. Go to Settings > Error Workflow and point it to a workflow that sends a Slack message or email when any workflow fails. This way you are alerted immediately if a signal is missed.

Rate limit awareness

The Rodz API allows 100 requests per minute. If you are processing a large backlog, add a Wait node between batches to stay under the limit. The API returns a 429 Too Many Requests status code with a Retry-After header when you exceed the limit. Your retry logic should respect this header.

Step 8: Monitor and maintain your workflows

Once your workflows are live, keep an eye on them.

  • Execution log: n8n stores execution history for every workflow. Review it periodically to catch silent failures (e.g., a CRM node that returns 200 but creates a duplicate record).
  • Workflow versioning: If you self-host n8n, back up your workflows by exporting them as JSON. Store these exports in version control alongside your application code.
  • Credential rotation: Rotate your Rodz API key periodically. Update the credential in n8n and the process is seamless since no workflow nodes reference the raw key.
  • n8n updates: Keep your n8n instance updated to benefit from security patches and new nodes. If you run Docker, this is as simple as pulling the latest image and restarting the container.

n8n vs Make: Which should you choose for Rodz?

Both n8n and Make are excellent automation platforms. The right choice depends on your team’s priorities. Here is a side-by-side comparison.

Criterian8nMake

CommunityActive open-source community, GitHub discussionsLarge user community, template library
Best for Rodz integrationTeams that want full control, custom logic, and no per-operation costsTeams that want a quick setup with minimal infrastructure management

Bottom line: If you want to self-host, need deep customization, or expect high signal volumes where per-operation pricing becomes expensive, go with n8n. If you prefer a managed service with more pre-built connectors and a gentler learning curve, Make is a strong option. Either way, the Rodz API works identically with both platforms.

Frequently asked questions

Does n8n have a native Rodz integration?

Not yet. Rodz is a REST API, so you connect to it using n8n’s built-in HTTP Request node. This node supports all HTTP methods, custom headers, query parameters, and request bodies. It works exactly like a native integration, just without a branded icon in the node picker. If the community builds a dedicated Rodz node in the future, it will simplify the setup, but the HTTP Request approach is fully production-ready.

Can I self-host n8n and still receive Rodz webhooks?

Yes, but your n8n instance must be reachable from the public internet. Rodz webhook deliveries originate from Rodz servers, so they need a URL they can POST to. If you run n8n behind a firewall, set up a reverse proxy (Nginx, Traefik, Caddy) with a valid TLS certificate and point your domain to it. Then use that public URL when registering the webhook with the Rodz API. Detailed webhook setup instructions are in the webhook guide.

How do I handle rate limits when polling the Rodz API from n8n?

The Rodz API allows 100 requests per minute. If your polling workflow runs every 5 minutes and makes a single request per run, you are well within the limit. For workflows that paginate through large result sets or chain multiple API calls (signals + enrichment), add Wait nodes between requests or use n8n’s built-in “Retry On Fail” with exponential backoff. The API returns a 429 status code with a Retry-After header when the limit is exceeded. Consult the API reference for full rate limit details.

Can I use n8n to sync Rodz signals with multiple CRMs at the same time?

Absolutely. One of n8n’s strengths is parallel branching. After receiving a signal, add a Switch or IF node, then branch out to as many destinations as you need: HubSpot, Salesforce, Pipedrive, a Google Sheet, a Postgres database. Each branch runs independently, so a failure in one does not block the others. This is particularly useful for companies that run different CRMs across regions or business units.

What happens if my n8n instance goes down and misses a webhook?

Rodz retries failed webhook deliveries with exponential backoff over a 24-hour window. If your n8n instance is down for a few minutes, the retry mechanism will catch up once it is back online. For extended outages, you can use the polling approach as a fallback: run a catch-up workflow that queries the Rodz API for signals created during the downtime window. Combining webhooks for real-time processing with a periodic polling safety net is a best practice for mission-critical workflows.

Is n8n free to use with the Rodz API?

n8n is free if you self-host it. You can run it on any server, VPS, or even a Raspberry Pi. There are no per-operation fees, no execution limits, and no artificial throttling. The only costs are your server infrastructure and the Rodz API plan itself. If you prefer the managed cloud version, n8n offers paid plans starting around $20 per month, which include hosting, automatic updates, and support. Either way, there are no additional charges on the Rodz side for using n8n as your automation layer.

How do I test my n8n workflow before going live?

n8n has a built-in test mode. Click the “Test Workflow” button (or press the play icon on individual nodes) to run the workflow with real data without activating it permanently. For webhook-based workflows, n8n generates a test webhook URL that listens for a single incoming request. Trigger a test event from the Rodz dashboard or send a manual cURL request to the test URL, then inspect the output of each node in the execution panel. Once everything looks correct, activate the workflow and it will run automatically.

Can I version-control my n8n workflows?

Yes. n8n allows you to export any workflow as a JSON file. Download the JSON, commit it to your Git repository, and you have a full history of changes. For teams that self-host, you can also use the n8n CLI to export and import workflows programmatically, making it easy to integrate with CI/CD pipelines. This approach is especially valuable when you have multiple environments (staging, production) and want to promote tested workflows through a review process.

Next steps

You now have everything you need to connect n8n to the Rodz API and build automated signal workflows. Here is what to do next:

  1. Start with a single signal type. Pick the most impactful signal for your team (fundraising, job postings, leadership changes) and build a workflow that routes it to one destination.
  2. Add enrichment. Once the basic flow works, chain an enrichment call to fill in firmographic data before pushing to your CRM.
  3. Layer in error handling. Add retry logic, an error notification workflow, and rate limit awareness.
  4. Scale to more signals. Expand the Switch node to cover additional signal types and add more destination branches.
