Google Ads — How to Obtain Setup Information
1. Open Google’s “First call” guide for the Google Ads API:
https://developers.google.com/

2. Customer ID (Client Account)
Go to https://ads.google.com/, sign in, choose the ad account, and copy the Customer ID (copy the digits only, without dashes).

3. Developer Token (Manager Account required)
Switch to your Manager account (MCC). In Google Ads, go to Admin → API Center to find or request your Developer token.


4. OAuth Client ID & Client Secret
Open Google API Console credentials page:
https://console.cloud.google.com/
Select an existing project or create a new one, then go to Credentials to create/find your OAuth Client ID and Client Secret.




Open Google Auth Platform Clients page:
https://console.cloud.google.com/auth/clients


5. Refresh Token
Use Google OAuth Playground to generate the Refresh token:
https://developers.google.com/oauthplayground




6. Token Expiration & Production Status
After completing the steps above, proceed to your next integration step. Note that tokens generated while the app is in testing can expire after 7 days. To avoid short-lived tokens, change your OAuth app’s publishing status to Production before issuing long-term tokens.
