This is the first time I'm using External API activity in ACS. I tried to execute the workflow. I'm getting the following error. Please advise what went wrong.
- Inbound mapping and outbound mapping are done
- No issues in column definition
- Tried to set the request headers as "Accept: application/json" and "Content-Type: application/json"
The issue is on server side.
The called URL is returning content-type HTML which is not supported by the External API activity.
So either the wrong URL was used or the server delivers a wrong content type.
