Using the Cloud Billing Budget API

Learn how to send a few simple requests to the Cloud Billing Budget API.

For a full list of methods, see the REST API or RPC API reference documentation.

Before you begin

You should do the following before reading this guide:

1. Read Cloud Billing Budget API Overview.
2. Read Cloud Billing Budget API Prerequisites.
3. Perform setup steps.

Identify your Billing Account ID

For every Cloud Billing Budget API call, you will need your Billing account ID.

1. Go to the Google Cloud Console Manage billing accounts page.
2. On the My billing accounts tab, you will see the list of billing accounts by name and ID. Locate the Billing account ID for the account where you will be managing budgets.

Calling the API

The following samples show how to send a few simple requests to the Cloud Billing Budget API.

A budget can be applied to an entire billing account, or scoped (filtered) to a subset of projects and/or products using granular budget filters to monitor specific slices of your costs across groups of projects and services.

Note: A single Cloud Billing Account cannot have more than 5,000 budgets associated with it at a time. See Quotas and Limits for additional information.
