API Orchestrator - Error 500


I’m trying to use API Orchestrator.

My goal is to add a queue item by API Orchestrator. I’mg using HTTP activities from orchestrator:

  1. HTTP post - Authentication
  2. I get a 200 and a result code XXXXXX
  3. HTTP post - Adds a new queue item
    3.1. Adding parameters with the content of the queue item
    3.2. Adding a header with the result code of the step 2

The result is 500 - An error has ocurred.

Anyone may help us?

I cannot access to the URL you provide.


Check your Headers:
