The InvoiceService is now available for all API users starting with version 6 of the Google Ads API. Earlier API versions will continue to only support this service for allowlisted accounts.
This service retrieves the monthly invoices of Google Ads accounts. Each returned Invoice comes loaded with data (for example: adjustments, regulatory costs, taxes, account budgets) and can be downloaded as a PDF file. Google Ads manager accounts can use the data to automatically reconcile customer invoices. To get started, read through our dedicated guide.
