HTTP Request Action

The HTTP Request Action node is your Swiss-Army-knife for interacting with third-party REST APIs. Use it to send HTTP requests and seamlessly integrate Helmut4 with any REST-based external system.

Configurable Settings

• Async Enable or disable asynchronous execution.

• Domain Name The base domain of the target API (e.g., api.example.com).

• Path The endpoint path to append to the domain (e.g., /v1/users).

• Method The HTTP verb to use: GET, POST, PUT, PATCH, or DELETE.

• Headers A set of request headers in Key: Value format.

• Body The JSON payload to include in the request (for methods that support a body).

• Skip SSL/TLS Verification Disable certificate validation for HTTPS requests—handy when the endpoint uses a self-signed certificate.

• Timeout Maximum time (in seconds) to wait for a response.

Response Handling

All response data—including the status code, headers, and body—is captured in the node’s response object. You can access it via wildcards:

• {node.result.?}

• {stream.last_result}

The object is organized into sections such as code (status code), headers (response headers) and body (response payload), making it easy to extract exactly what you need.
