Google Merchant Center / API Reference
merchant_register_developer
Merchant Center tool. Register this server's Google Cloud project with a Merchant Center account. Required once per account before any other Merchant API call works -- until then Google answers every request with 401 "GCP project not registered". Must be run by a login with ADMIN access on that account. A project can be registered with one account at a time; ALREADY_REGISTERED means it is linked to a different one. Args: account_id: Merchant Center account id. developer_email: Contact email for API notices. Defaults to the connected Google login.
This is a read-only tool: it returns merchant register developer for your Google Merchant Center account. It changes nothing.
