The HTTP request block enables you to perform an HTTP request within your callflow. This allows you to fetch information from your APIs or send data collected during the callflow execution to your APIs.

Important notes

Timeout: The request has a timeout set to 15 seconds. If the server does not respond within this time, the request will be cancelled, and the Error output will be used.
Redirects: FlowBuilder does not allow redirect responses (HTTP 3xx). If the request is redirected, it will be cancelled, and the Error output will be used.
Response Size Limit: Responses larger than 1 MB are not accepted due to security considerations. If the response exceeds this limit, it will be ignored, and the Error output will be used.
