Migrating Billing Features from the AdWords API to the Google Ads API

This guide compares the billing terms used in both APIs:

Google Ads API	AdWords API
Payments account	Billing account
Payments profile	Billing customer
Billing setup	n/a
Account budget	Budget order

Payments account (Google Ads API) vs. billing account (AdWords API)

Both represent the same thing and each is indexed by a 16-digit ID (e.g., 1234-5678-9012-3456). This ID is needed to create a new billing setup in the Google Ads API.

• In the Google Ads API, you can retrieve this entity directly using PaymentsAccountService.ListPaymentsAccounts, which will return all available Payments accounts for your authenticated Google Ads account. You can also create a new Payments account at the same time you create a billing setup.

• In the AdWords API, you use BudgetOrderService to get available billing accounts using getBillingAccounts.

Payments profile (Google Ads API) vs. billing customer (AdWords API)

Both represent the same thing and each is indexed by a 12-digit ID (e.g., 1234-5678-9012).

• You need this ID to create a new Payments account in the Google Ads API.

• In contrast, the AdWords API doesn't allow you to manipulate this entity directly, but it appears as a part of BudgetOrder.

Billing setup (Google Ads API)

• A billing setup is a link between a Google Ads account and a Payments account. This entity is needed for creating a new account budget in the Google Ads API.

• The AdWords API doesn't allow you to manipulate this entity directly.

Account budget (Google Ads API) vs. budget order (AdWords API)

Both represent the same thing and each is indexed by an ID.

• In the Google Ads API, you manipulate an AccountBudget via the AccountBudgetProposal. Read more about mutating account budgets.

• In the AdWords API, you use the BudgetOrderService to create a new BudgetOrder. Read more about budget orders.
