About the Payment Details API

The Payment Details API retrieves the current and upcoming billing details for a site's Google Ads account, including ad spend for the active billing period and any scheduled future payments. The data is calculated from subscription information rather than queried live from Google Ads.

With the Payment Details API, you can:

  • Retrieve the current and upcoming billing periods for the site's Google Ads account, including ad spend for each.
  • Retrieve the account's remaining credit balance and scheduled upcoming payment amounts.

Before you begin

It's important to note the following points before starting to code:

  • A Google Ads account must exist for the site before calling this service. Use the Account API to create one.
  • The response contains the current and, where available, the next upcoming billing period. It is not a historical ledger of past months.
  • The data is calculated from subscription information, not queried live from Google Ads.
  • creditBalance is a single account-level value, not scoped to a billing period. It can be negative, indicating outstanding debt before the charge has been applied. It's only populated for accounts on a weekly billing cycle.
  • Use upcomingPayments to retrieve future billing amounts. The monthlyPayments field is deprecated and currently returns the same data as upcomingPayments.
  • Amounts are expressed as decimal strings in the account's billing currency (for example, "123.45").
  • If the site's billing setup for the Google Ads account isn't complete, this call may fail.

Use cases

Terminology

  • Payment Record: An entry showing the total ad spend and billing details for the current or an upcoming billing period of a site's Google Ads account.
  • creditBalance: The remaining promotional or prepaid credit on the account. A negative value indicates outstanding debt before the charge is applied.
  • upcomingPayments: The list of future scheduled billing amounts, replacing the deprecated monthlyPayments field.
