I am trying to create data mashup using REST mashup webservice.
The web service is returning code 200 upon simulation (none of the return parameters are visible though). Assuming that code 200 is a sign of successful web service execution, I tried to add it to the data mashup. Nevertheless, once the preview button is clicked, nothing is shown but error message.
The API certificates are installed to the C4C.
Can you please advice where I am going wrong?
