n8n Integration

n8n is a fair-code, extendable workflow automation tool. You can connect Reloop to your n8n workflows using either:

1. SMTP Connection (using n8n's built-in Send Email node)
2. REST API Connection (using n8n's built-in HTTP Request node)

You can route emails directly using n8n's native Send Email node configured with Reloop's SMTP credentials.

3. Save the credential.

Step 3: Set Email Parameters

Configure the email body and headers:

• From Email: Enter a verified email address from your Reloop sending domain (e.g., app@yourdomain.com).
• To Email: Map the recipient's email address dynamically from prior nodes.
• Subject: Enter a subject line.
• HTML / Text: Choose your email body format and insert your content.

Method 2: REST API via HTTP Request Node

Use n8n's HTTP Request node to access advanced API features such as templating, tag tracking, attachments, or scheduling.

Step 1: Add the HTTP Request Node

1. Click the + icon to add a new node.
2. Search for and select HTTP Request.

Step 2: Configure Node Parameters

Configure the node parameters for the Reloop Send Mail API:

• Method: POST
• URL: https://reloop.sh/api/mail/v1/send
• Authentication: Header Auth (or choose None and add it manually in Headers)
• Headers:
  • Name: x-api-key
  • Value: Your Reloop API Key
  • Name: Content-Type
  • Value: application/json
• Specify Body: Using JSON
• Body Parameters: Toggle to JSON format and enter the payload:

{
  "from": "Marketing <marketing@yourdomain.com>",
  "to": "={{ $json.email }}",
  "subject": "Thank you for subscribing!",
  "html": "<h1>Welcome {{ $json.name }}!</h1><p>We are glad to have you aboard.</p>",
  "tags": [
    {
      "name": "campaign",
      "value": "onboarding_n8n"
    }
  ]
}

Note: Use n8n's expression syntax ={{ ... }} to pull data from your webhook or database triggers.

Step 3: Test and Verify

1. Click Test step or Execute Node in n8n.
2. Inspect the JSON response to ensure it returns a success confirmation:

{
  "success": true,
  "messageId": "msg_8d8b9c2a1e...",
  "status": "sent"
}

3. Check your recipient inbox and check the Reloop Dashboard Logs to confirm the email was delivered successfully.
