External API activity - Error in Content type

[#1]

Hi all,

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.

Hi @ramon_bisswanger Yes, the url is not returning the Content-Type as 'application/json'. I tried to figure it out by myself and see that url was returning empty Content-Type. I had to modify server side changes to return Content Type as application/json and then it worked fine. Thanks for your help.
