Troubleshooting / Unable to Call API via POST Method

Generally, there are the following possibilities:

1. Confusion between "Simplified" and "Standard" Forms

Check if the URL and request body are correct, and avoid mixing "Simplified Form" and "Standard Form."

For details, please refer to the Guide / Development Guide / Basics / Calling Functions

2. HTTP Request Redirected to HTTPS Request

Confirm if DataFlux Func is behind a reverse proxy server like Nginx, and if the reverse proxy server redirects your HTTP request to an HTTPS request.

If so, your POST http://xxxxx will be redirected to GET https://xxxxx, and the content in the original request body will be lost.

Changing the request to directly send POST https://xxxxx will solve the problem.
