How to Connect N8N to Manyreach Using API Integration

N8N is a powerful workflow automation platform that can seamlessly integrate with Manyreach's API to automate your cold email campaigns. This integration allows you to automatically add prospects, trigger campaigns, and manage your outreach workflows without manual intervention.

Step 1: Get Your Manyreach API Key

1. Log in to your Manyreach dashboard

2. Navigate to Account Settings in the left sidebar

3. Click on the API tab in the top menu

4. Copy your API Key from the display field (it will look like: ca5b617f-cd2a-412b-925f-10g628b279ds)

Important Note: Keep your API key secure and never share it publicly. If you suspect it's been compromised, use the Reset API Key button to generate a new one.

Step 2: Set Up N8N HTTP Request Node

1. Open your N8N workflow editor

2. Add a new HTTP Request node to your workflow

3. Configure the node with these basic settings:

   • Method: Select the appropriate method (GET, POST, etc.)

   • URL: Enter the Manyreach API endpoint (e.g., https://app.manyreach.com/swagger/docs#/)

Important Note: To get the correct URL, head over to:  Account setting > API > Choose the URL based on the operation you wish to perform

Step 3: Configure Common Manyreach API Endpoints

Pro Tip: Start with simple GET requests to verify your API connection before moving to more complex POST operations that modify your data.

Step 5: Build Advanced Workflows

Once your basic connection is established, you can create sophisticated automation workflows:

1. Lead Generation Pipeline: Connect lead scraping tools → N8N → Manyreach prospect import

2. Multi-Channel Sequences: Trigger email campaigns based on LinkedIn actions or website visits

3. Response Management: Automatically categorize responses and trigger follow-up actions

Common Mistakes to Avoid

Remember: Always include the apikey header in every request to Manyreach. Missing this authentication will result in 401 Unauthorized errors.

Important Note: Manyreach's API has rate limiting in place. If you're processing large volumes of data, implement delays between requests to avoid hitting rate limits.

Troubleshooting Common Issues

"401 Unauthorized" Error

• Verify your API key is correctly copied (no extra spaces)

• Check that your API key hasn't been reset recently

"404 Not Found" Error

• Double-check the API endpoint URL for typos

• Verify the specific endpoint exists in Manyreach's API documentation

Data Not Appearing in Manyreach

• Confirm your JSON payload structure matches Manyreach's expected format

• Check that required fields (like email addresses) are properly formatted

• Verify the campaign ID exists if you're adding prospects to a specific campaign

Pro Tip: Use N8N's Webhook node as a trigger to create real-time integrations. For example, when a form is submitted on your website, it can automatically add the lead to your Manyreach campaign and start the outreach sequence.
