The http node makes HTTP requests to external APIs. It supports all standard HTTP methods, custom headers, query parameters, and request bodies.

Examples

​
GET Request

{
  "id": "get_user",
  "type": "http",
  "config": {
    "method": "GET",
    "url": "https://api.example.com/users/{{request.query.user_id}}"
  }
}

​
GET with Query Parameters

{
  "id": "search_users",
  "type": "http",
  "config": {
    "method": "GET",
    "url": "https://api.example.com/users",
    "query": {
      "search": "{{request.query.q}}",
      "limit": "10",
      "offset": "{{request.query.page | multiply:10}}"
    }
  }
}

​
POST with JSON Body

{
  "id": "create_user",
  "type": "http",
  "config": {
    "method": "POST",
    "url": "https://api.example.com/users",
    "headers": {
      "Authorization": "Bearer {{env.API_KEY}}",
      "Content-Type": "application/json"
    },
    "body": {
      "name": "{{request.body.name}}",
      "email": "{{request.body.email}}",
      "role": "user"
    }
  }
}

​
PUT Request

{
  "id": "update_user",
  "type": "http",
  "config": {
    "method": "PUT",
    "url": "https://api.example.com/users/{{user_id}}",
    "body": {
      "name": "{{request.body.name}}",
      "updated_at": "{{now}}"
    }
  }
}

​
DELETE Request

{
  "id": "delete_user",
  "type": "http",
  "config": {
    "method": "DELETE",
    "url": "https://api.example.com/users/{{request.body.user_id}}"
  }
}

​
With Custom Headers

{
  "id": "api_call",
  "type": "http",
  "config": {
    "method": "POST",
    "url": "https://api.example.com/webhook",
    "headers": {
      "Authorization": "Bearer {{env.API_TOKEN}}",
      "X-Request-ID": "{{request_id}}",
      "X-Timestamp": "{{now}}",
      "Accept": "application/json"
    },
    "body": "{{payload}}"
  }
}

​
With Timeout

{
  "id": "slow_api",
  "type": "http",
  "config": {
    "url": "https://slow-api.example.com/process",
    "timeout": 60000
  }
}

​
Error Handling

​
on_error: "abort" (default)

If the request fails (network error, timeout, non-2xx status), the flow stops immediately. 
{
  "id": "critical_api",
  "type": "http",
  "config": {
    "url": "https://api.example.com/critical",
    "on_error": "abort"
  }
}

​
on_error: "continue"

Errors are captured in the output instead of failing the flow: 
{
  "id": "optional_api",
  "type": "http",
  "config": {
    "url": "https://api.example.com/optional",
    "on_error": "continue"
  }
}
Then check the result: 
{
  "id": "check_result",
  "type": "condition",
  "config": {
    "conditions": [
      {
        "if": "{{optional_api.output.success}} == true",
        "then": ["process_data"]
      }
    ],
    "else": ["use_fallback"]
  }
}

​
Body Handling

​
JSON Body (default)

Objects are automatically serialized as JSON: 
{
  "body": {
    "name": "John",
    "age": 30
  }
}

​
String Body

Strings are sent as-is: 
{
  "body": "raw string content",
  "content_type": "text/plain"
}

​
Template Body

Use templates for dynamic content: 
{
  "body": "{{prepared_payload}}"
}

​
Response Parsing

  • JSON responses are automatically parsed into objects
  • Other responses are returned as strings
  • Check Content-Type header to determine response format

​
URL Templates

The URL supports template expressions: 
"url": "https://api.example.com/users/{{user_id}}/posts/{{post_id}}"  # Path parameters
"url": "https://{{env.API_HOST}}/v1/users"                            # Dynamic host
"url": "https://api.example.com/{{api_version}}/users"                # Conditional path

​
Common Patterns

​
Authenticated Request

{
  "id": "authenticated_call",
  "type": "http",
  "config": {
    "url": "https://api.example.com/protected",
    "headers": {
      "Authorization": "Bearer {{auth_token}}"
    }
  }
}

​
Pagination

{
  "id": "fetch_page",
  "type": "http",
  "config": {
    "url": "https://api.example.com/items",
    "query": {
      "page": "{{current_page}}",
      "per_page": "50"
    }
  }
}

​
Webhook Call

{
  "id": "send_webhook",
  "type": "http",
  "config": {
    "method": "POST",
    "url": "{{webhook_url}}",
    "headers": {
      "X-Webhook-Secret": "{{env.WEBHOOK_SECRET}}"
    },
    "body": {
      "event": "order.created",
      "data": "{{order}}"
    }
  }
}
