Google Ads OAuth is a product workflow, not a settings screen_

The Google Ads API uses OAuth 2.0 so applications can act on an account without collecting Google credentials. The authorization flow still has to explain which account is connected and what the application will do.

A technically valid token can still create a poor product: wrong account selection, confusing consent, stale refresh credentials, or no way for a customer to disconnect.

What changes in practice_

Model connection state explicitly, store credentials server-side, verify the selected customer, and expose reauthorization and revocation paths.

• Never collect account passwords.
• Keep tokens out of the client.
• Show account identity and connection health.

Our take_

The durable advantage is not adopting the newest tool first. It is building the identity, state, evidence, and operating boundaries that let a real team own the system after launch.
