When I try it to use the CPO activity Web HTTP Request it fails with the following error
Cannot send a content-body with this verb-type.
I think the issue here is the content type. The default value is application/xml; charset=utf-8 in the activity, I tried changing it to text, html and json but still did not work. I cannot leave the content type emty either in the activity.
Does anyone has any suggestion how to make a REST call from CPO using the activity Web HTTP Request
