There are a few scenarios that can cause the "You cannot authorize the app error." Continue reading to find your scenario and the steps to add the app.
Scenarios:
Scenario 1. "An account admin is required to add chatbots. Please contact your account admin or IT administrator to add this bot."
To fix it: Have your admin add the app for you, or have your admin give you the "Marketplace" permission, located here: https://zoom.us/role.
Scenario 2. "An account admin is required to add this type of app. Please contact your account admin or IT administrator to add this app."
To fix it: Have your admin add the app for you, or have your admin give you the "Marketplace" permission, located here: https://zoom.us/role.
Scenario 3. "This app cannot be added outside of the developer's account. Please contact the application developer to get support with adding this application."
To fix it: To share apps outside of your (the developer's) account, you must publish the app to the Zoom App Marketplace. If you are looking to test your app externally before publishing it, you can request a publishable URL. You can also request a publishable URL if you want to enable a limited set of external users to add your app.
Scenario 4. "You cannot add the app because you don't have the required permissions. Please contact your IT administrator for permission and try again."
To fix it: Have your admin add the app for you, or have your admin give you the respective permission to match the scope you set for the app. You can see which permission you need by visiting: https://marketplace.zoom.us/apphelp/{YourAppIDFromUrl}
Have your admin go to https://zoom.us/role and give you the respective permission:
Once you have been granted the respective permission, sign out and back into your Zoom account. You should see a checkmark instead of an X for the permission you were missing.
You should now be able to add the app.
