API access using own credentials (server to server flow)

This guide will walk you through how to setup OAuth2 for API access using your own credentials using server to server flow. These steps only need to be done once, unless you revoke or delete your OAuth2 credentials.

Step 1 - Creating OAuth2 credentials

Follow the steps for the product you're using to generate a *service account ID and a .p12 file, then come back to this page.

If you're an AdWords user, please note that this flow requires a Google Apps Domain.

Step 2 - Setting up the client library

Under the authentication section of your adwords_api.yml or dfp_api.yml file, insert your service account ID and path to your *.p12 file.

:oauth2_issuer: = INSERT_OAUTH2_SERVICE_ACCOUNT_ID_HERE
:oauth2_keyfile: INSERT_OAUTH2_PATH_TO_P12_HERE
