Use the OAuth authentication standard to connect to Google Ads. You can authenticate with a user account or with a service account. A service account is required to grant organization-wide access scopes to the adapter. The adapter facilitates these authentication flows as described below.

Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes to the adapter.

You need to create an OAuth application in this flow. See Creating a Custom OAuth App in the Getting Started section to create and authorize an app. You can then connect to Google Ads data that the service account has permission to access.

After setting the following connection properties, you are ready to connect:

InitiateOAuth: Set this to GETANDREFRESH.

OAuthClientId: Set this to the Client Id in your app settings.

OAuthClientSecret: Set this to the Client Secret in your app settings.

OAuthJWTCertType: Set this to "PEMKEY_FILE".

OAuthJWTCert: Set this to the path to the .pem file you generated.

OAuthJWTCertPassword: Set this to the password of the .pem file.

OAuthJWTCertSubject: Set this to "*" to pick the first certificate in the certificate store.

OAuthJWTSubject: Set this to the email address of the user for whom the application is requesting delegate access. Note that delegate access must be granted by an administrator.

DeveloperToken: Set this to the developer token of the AdWords account. You can get a developer token by signing up for the AdWords API. To do this, log in to the AdWords site with your MMC account and navigate to Settings -> Account Settings -> AdWords API Center. Apply for API access and wait for Google to contact you via email with more instructions. You should receive a token with a pending status. This token is only for testing and does not allow you to connect to live data. Google should contact you to fill out a questionnaire and once this has been received and approved by Google, you will receive your active developer token.

ClientCustomerId: Set this to the client customer Id of the AdWords account. You can find this value in your AdWords account. This value is not the same as the Id of the MCC account. You need to provide the lowest-level Ids to retrieve data.

When you connect the adapter completes the OAuth flow for a service account.
