I have created an app and added permissions to use the Marketing API. I am using the Marketing API to retrieve ad performance data.

I am attempting to complete the Data Use Checkup but am unsure what to input for the app URL and access method for app review under the Testing Instructions. When I input the value from My App -> Settings -> Basic -> Website URL into the URL Debugger, I receive the following error:

"The following required properties are missing: fb."

Could you please assist me in proceeding with this?
