I'm getting this:
"An error occurred. Please try again later.
API Error Code: 191
API Error Description: The specified URL is not owned by the application
Error Message: Invalid redirect_uri: Given URL is not allowed by the Application configuration."
Now this is when previewing it from CS2 not an uploaded version if that makes a difference or not.
I have the App kkey in place as well as the secret key.
I place the plug in on the page and added the action as in the capx file.
