How to register a Google developer app and get OAuth 2 credentials

Registering a Google developer app and obtaining OAuth 2 credentials involves several key steps within the Google Cloud Platform. Initially, users must create a new project or select an existing one in the Google Cloud Console, then enable the necessary APIs that their app will require, such as Gmail or Google Drive. Following this, configuring the OAuth Consent Screen is crucial, where users specify the scopes needed for app permissions and fill out necessary information for Auth Branding. Depending on the type of scopes chosen, particularly Restricted or Sensitive ones, it may be necessary to contact Unified's Support for setting up a CNAME for the API URL to secure Google’s approval. Afterward, OAuth 2.0 credentials must be created by configuring authorized redirect URIs, and the Client ID and Secret obtained need to be entered into the integrations. Finally, publishing the application involves going through potential verification processes to make the app publicly available, during which the app name will appear on the authorization consent screen once approved.
