Connecting to a rest api gives me a 500 internal server error

Connecting to a rest api gives me a 500 internal server error

  
Sorry just a beginner but I am trying to connect to a rest api but always get the return 500 internal server error. When I test the rest api through a different way I get a normal response.

What did I do?
- Added the rest api in outsytems with a json response
- The rest api is added with the json response as structure
- Added the action to my screen preperation
- On my webscreen added a tablerecord list
- In the source record list the action response

I am using outsystems cloud if you where wondering :-)
Hi Sander,

Check my answer on this topic on how to turn the detailed logging on: http://www.outsystems.com/forums/discussion/14062/rest-400-errors/

With that setting you will be able to see exactly what the REST API is sending and recieving to be able to compare with the external tool.

Hope it helps.
