Thanks for the quick and detailed reply! I don’t know how I missed the notification.
when you authorise with this flow you will receive an ID Token and Access Token, you can use the Access Token received here for access to your API
Actually, I have already tried to use the access token from the native application to authorize the API but I got no success in that. The API would not accept the token (401 unauthorized error).
The application is built with Flutter and I have referenced this and this. I got the authentication working in the app (was able to login with google) but the access token somehow had invalid signature (checked on jwt.io).
It’s confusing because if any credentials or configuration was misconfigured I would not be able to login in the first place. Could you please give me an idea how to approach this?
