Connectivity Nodes

These nodes connect your workflows to external services and APIs.

HTTP Request

Makes HTTP requests to any URL or API.

Properties:

Authentication Options:

• None - No authentication
• Basic Auth - Username/password
• Bearer Token - Authorization header
• Header Auth - Custom header
• OAuth2 - OAuth credentials

Example - GET Request:

Method: GET
URL: https://api.example.com/users
Headers: 
  - Accept: application/json

Example - POST Request:

Method: POST
URL: https://api.example.com/users
Headers:
  - Content-Type: application/json
Body:
  {
    "name": "{{ $json.name }}",
    "email": "{{ $json.email }}"
  }

Output:

{
  "statusCode": 200,
  "headers": { },
  "body": { }
}

Error Handling:

• Enable "Continue on Fail" to handle errors gracefully
• Check $json.statusCode for response status
• Use If/Else to handle different status codes

Gmail

Sends emails via Gmail API.

Properties:

Requires: Google OAuth credentials with Gmail scope

Example:

To: {{ $json.email }}
Subject: Order Confirmation #{{ $json.orderId }}
Body: 
  Hi {{ $json.name }},
  
  Your order has been confirmed.
  
  Thanks!

Tips for API Integration

Rate Limiting

Use the Loop node with delays for rate-limited APIs.

Pagination

Use a Loop to fetch paginated results:

1. Make initial request
2. Check for next page
3. Loop until no more pages

Error Handling

1. HTTP Request (Continue on Fail: true)
2. If/Else ({{ $json.statusCode === 200 }})
   - True: Continue processing
   - False: Handle error
