Authorization

Google Search Ads 360
Prerequisites
Before creating a Google Search Ads 360 credential, you need to have a Google account with access to Google Search Ads 360 and have OAuth2 credentials (Client ID and Client Secret) configured in the Google Cloud Console. The OAuth2 credentials are required to authenticate with the Google Search Ads 360 API.
To obtain OAuth2 credentials, you need to create a project in the Google Cloud Console and enable the Google Search Ads 360 API (DoubleClick Search API) for that project. Once the API is enabled, you can create OAuth2 credentials (OAuth 2.0 Client ID) in the Credentials section of the Google Cloud Console. The OAuth2 credentials include a Client ID and Client Secret that are used to authenticate API requests. The required access scopes are https://www.googleapis.com/auth/doubleclicksearch and https://www.googleapis.com/auth/userinfo.email, which provide access to your Search Ads 360 data and user email information. For detailed information about setting up OAuth2 credentials and enabling the Google Search Ads 360 API, refer to the Google Ads API documentation.

OAuth2 Authentication
Google Search Ads 360 uses OAuth2 authentication to securely access the Google Search Ads 360 API. OAuth2 is an industry-standard authorization protocol that allows applications to access user data without requiring users to share their passwords.
-
Click the Authorize button to begin the OAuth2 authorization flow. This will redirect you to Google's authorization page where you will be asked to sign in with your Google account and grant permissions to Nexla to access your Google Search Ads 360 data.
During the OAuth2 authorization flow, you will be redirected to Google's authorization page. You must sign in with a Google account that has access to the Google Search Ads 360 account you want to connect. After signing in, you will be asked to grant permissions to Nexla to access your Google Search Ads 360 data. The required scopes are
https://www.googleapis.com/auth/doubleclicksearchandhttps://www.googleapis.com/auth/userinfo.email, which provide access to your Search Ads 360 data and user email information. Once you grant permissions, you will be redirected back to Nexla, and the authorization will be completed automatically. -
After completing the OAuth2 authorization flow, Nexla will automatically obtain and store the access token and refresh token needed to authenticate API requests. The access token is used to authenticate each API request, and the refresh token is used to obtain new access tokens when the current access token expires.
OAuth2 access tokens expire after a certain period for security reasons. Nexla automatically refreshes expired access tokens using the refresh token, so you typically do not need to re-authorize unless you revoke access or the refresh token expires. The access token is sent in the
Authorizationheader with theBearerprefix for all API requests to the Google Search Ads 360 API. For detailed information about OAuth2 authentication and token management, see the Google Ads API documentation.
Save the Credential
-
Once all of the relevant steps in the above sections have been completed, click the Save button at the bottom of the overlay to save the configured credential.
-
The newly added credential will now appear in a tile on the Authenticate screen during data source/destination creation and can be selected for use with a new data source or destination.
