This guide will walk you through how to setup OAuth2 for API access using your own credentials using service accounts. These steps only need to be done once, unless you revoke or delete your OAuth2 credentials.
Create OAuth2 credentials
Generate a service (delegate) account ID and a *.JSON
file
by following the linked instructions, then come back to this page.
Set up client library
Set the private key JSON file path and delegate account ID in your
configuration. If you're using a googleads.properties file, add the following:
jsonKeyFilePath=PRIVATE_KEY_FILE_PATH
impersonatedEmail=DELEGATE_ACCOUNT
If you're using environment variables, add the following to your Bash configuration or environment:
export GOOGLE_ADS_JSON_KEY_FILE_PATH=PRIVATE_KEY_FILE_PATH
export GOOGLE_ADS_IMPERSONATED_EMAIL=DELEGATE_ACCOUNT_ID
