How to obtain user email to input it on the developer dashboard

[FrankInasnity]

Hello! I'm implementing the Authorization Code Flow for my app. I can successfully POST the "/api/token" endpoint, but on other endpoints I get the following error:

"User not registered in the Developer Dashboard"

I'm aware that the user needs to be whitelisted on the developer dashboard, but I can't find the user email in the "/api/token" response. Is there a way to obtain the user email before inputting it to the dashboard?

Thanks!

Hey there, help's here!

You can't obtain the user's email address without authentication. You'll need to whitelist user accounts that are going to use your app beforehand. If you'd like to share your app with people that are not involved with the development of the app, you can request a quota extension on your Developer Dashboard. Let me know if you have any questions!

Have a great day and happy coding!
