HTTP Request Node

The HTTP Request node allows your flow to "communicate" with external systems. With it, you can fetch real-time data (e.g., dollar exchange rate, order status) or send information.

Configuration

This node works as a complete API client.

1. Method and URL

• Method: Choose the desired action (GET, POST, PUT, DELETE, PATCH).
• URL: The address of the service.
  • You can use variables to make the URL dynamic.
  • Example: https://api.store.com/orders/{{ input.order_number }}.

2. Headers

Mainly used for authentication.

• Key: Authorization
• Value: Bearer {{ input.api_token }}

3. Body

For methods like POST or PUT, you send data in JSON format.

• You can build the JSON using variables from other nodes.
• Example:

  {
    "client": "{{ extractor_cpf.cpfs[0] }}",
    "reason": "{{ llm.classification }}"
  }

4. Advanced Settings

• Timeout: Maximum time (in seconds) the flow waits for a response before failing (default: 360s).
• Content-Type / Accept: Defines the data format (usually application/json).

Output Variables

The node returns two crucial pieces of information for the continuity of the flow:

1. status_code (Number): The HTTP response code (e.g., 200 for success, 404 for not found, 500 for error).
2. detail (Object/Text): The body of the API response. If the API returns JSON, it will automatically be converted into an accessible object.

Example Response (JSON)

If you queried a Weather API, the variable {{ http_request.detail }} might contain:

{
  "city": "São Paulo",
  "temperature": 25,
  "condition": "Sunny"
}
