In Google Ads API, the “long-lived token” you want is the OAuth2 refresh token. It doesn’t have a fixed expiry (it lives until revoked or unused for a long time). Here’s the fastest, reliable way to get one and use it in Laravel.

OAuth Playground (fastest)

  • Go to the OAuth Playground
  • Click the gear (⚙️) → Use your own OAuth credentials → paste your Client ID and Client Secret.
  • In Step 1, select the scope: https://www.googleapis.com/auth/adwords
  • Click Authorize APIs and sign in with the Google account that owns your Google Ads (or MCC).
  • Click Exchange authorization code for tokens.
  • Copy the Refresh token shown. That’s your long-lived token.
  • Save it in your adsapi_php.ini or .env and you’re done.

If you don’t see a refresh token, you probably missed these parameters. Make sure the auth request includes:

  • access_type=offline
  • prompt=consent

If you git rejected by Google, make sure that redirect url is correctly set.

Go to: https://console.developers.google.com/auth/clients

and make sure "Aithorized redirect URIs" contains this uri:
https://developers.google.com/oauthplayground

And that is it!
