This guide shows you how to connect the Enrow API to n8n and build your first workflow: a single email search that returns its result automatically through a webhook. n8n is a workflow automation tool that lets you connect Enrow with hundreds of other services, and it can be self-hosted or run on n8n Cloud.
Don’t have n8n? Install n8n or use n8n Cloud to get started in minutes.

​
What do I need before I start?

To follow this guide you need two things:
  • n8n installed (self-hosted or cloud)
  • An Enrow API key (get one here)
Every Enrow request is authenticated with the API key in the x-api-key header — there are no OAuth flows or bearer tokens. For the full details, see Authentication.

​
How do I store my Enrow API key in n8n?

Store the API key once as a reusable Header Auth credential so you don’t paste it into every node:
  1. In n8n, open Credentials → New
  2. Choose Header Auth
  3. Set Name to x-api-key
  4. Set Value to your Enrow API key
  5. Save the credential (for example, name it “Enrow API”)
You can now reference this credential from any HTTP Request node across your workflows.

​
How do I build a workflow that finds a single email?

The workflow has three parts: a trigger to start it, an HTTP Request node that calls the Find Single Email endpoint, and a Webhook node that receives the result when the search completes.

​
Step 1: Create a new workflow

  1. Open n8n
  2. Click “New Workflow”
  3. Name it “Enrow - Find Email”

​
Step 2: Add a Manual Trigger

  1. Click the ”+” button
  2. Search for “Manual Trigger”
  3. Add it to your canvas
The Manual Trigger lets you run the workflow on demand while you test it.

​
Step 3: Add an HTTP Request node

  1. Click ”+” after the Manual Trigger
  2. Search for “HTTP Request”
  3. Configure it:
Authentication:
  • Authentication: Generic Credential Type
  • Generic Auth Type: Header Auth
  • Name: x-api-key
  • Value: YOUR_ENROW_API_KEY
Request:
  • Method: POST
  • URL: https://api.enrow.io/email/find/single
  • Body Content Type: JSON
  • JSON Body:
{
  "company_domain": "apple.com",
  "fullname": "Tim Cook"
}

​
Step 4: Test the workflow

  1. Click “Execute Workflow” at the top
  2. You should see a response with a search id
  3. The search is processing asynchronously — the id is what you’ll use to retrieve the result

​
Step 5: Receive results with a webhook

Enrow runs searches asynchronously, so instead of polling, let n8n receive the result automatically. The Enrow API will POST the result to your webhook URL once the search finishes. See How webhooks work for the full flow.
  1. Add a “Webhook” node to your canvas
  2. Set:
    • HTTP Method: POST
    • Path: enrow-email-result
  3. Copy the Production URL (e.g., https://your-n8n.com/webhook/enrow-email-result)
  4. Update your HTTP Request node JSON to include the webhook in settings: 
{
  "company_domain": "apple.com",
  "fullname": "Tim Cook",
  "settings": {
    "webhook": "https://your-n8n.com/webhook/enrow-email-result"
  }
}
  1. Save and activate the workflow
Now when the search completes, Enrow will POST the result to your webhook node.

​
Can I import a ready-made workflow?

Yes. Copy the JSON below to get started quickly, then import it into n8n. 
{
  "name": "Enrow - Find Email with Webhook",
  "nodes": [
    {
      "parameters": {},
      "name": "Manual Trigger",
      "type": "n8n-nodes-base.manualTrigger",
      "typeVersion": 1,
      "position": [250, 300]
    },
    {
      "parameters": {
        "method": "POST",
        "url": "https://api.enrow.io/email/find/single",

        "options": {}
      },

        }
      }
    },
    {
      "parameters": {
        "httpMethod": "POST",
        "path": "enrow-email-result",
        "responseMode": "onReceived",
        "options": {}
      },
      "name": "Webhook",
      "type": "n8n-nodes-base.webhook",
      "typeVersion": 1,
      "position": [650, 300],
      "webhookId": "your-webhook-id"
    }
  ],
  "connections": {
    "Manual Trigger": {
      "main": [[{"node": "Find Email", "type": "main", "index": 0}]]
    },
    "Find Email": {
      "main": [[{"node": "Process Result", "type": "main", "index": 0}]]
    }
  }
}
To import the workflow:
  1. Copy the JSON above
  2. In n8n, click ”…” → “Import from File/URL/String”
  3. Paste the JSON
  4. Update the API key in credentials
  5. Activate!

​
What are the best practices for n8n + Enrow?

Create a Header Auth credential with:
  • Name: x-api-key
  • Value: Your Enrow API key
Reuse this credential across workflows instead of pasting the API key into each node.
Webhooks are more reliable than polling with Wait nodes. Always pass the settings.webhook parameter so Enrow delivers the result as soon as the search completes.
Add an “Error Trigger” node to catch and handle API errors. See Error handling and Status codes for the response formats to expect.
If you’re processing many contacts, use the Find Bulk Emails endpoint (up to 5,000 searches per batch) instead of looping single requests.

​
FAQ

A 401 Unauthorized means the API key is missing or invalid. Check that the Header Auth credential has x-api-key as the Name and your valid Enrow API key as the Value. See Authentication for details.
First, make sure the workflow is activated, not just saved. Then confirm the webhook URL in the settings.webhook parameter matches the Webhook node’s Production URL. You can test the URL directly with a tool like Postman. See How webhooks work for the delivery flow.
A rate-limit error means you sent too many requests too quickly. Add a “Wait” node between batch operations, or use the bulk endpoints instead of looping. See Rate limits for the current limits.
