This document describes the limits and quotas for the Google Tag Manager API.
Overview
Google Tag Manager is used by millions of sites. To protect the system from receiving more data than it can handle, and to ensure an equitable distribution of system resources, certain limits have been put in place. Our policies are as follows and are subject to change.
Obtaining Quota
You must register your application in the Google API Console to receive any quota; no unregistered quota will be allowed. When you register a new application, you are given a unique client ID to identify each application under that project. Read the Keys, access, security, and identity section of the API Console guide to learn more about how client IDs identify applications.
General Quota Limits
The following quota limits apply to all requests made to the Tag Manager API:
- 10,000 requests per project per day.
- 0.25 queries per second (QPS) per project.
These quotas are independent of those you can set in the API Console. If the you set the project's per-user limit above 0.25 QPS, the Google Tag Manager quota policy will still take effect and limit per-project requests to 0.25 QPS.
Exceeding Quota Limits
If quota is exceeded, Google Tag Manager API returns an error for
additional requests: HTTP status code 403 Forbidden
and
a message indicating that the specific account has insufficient
quota to proceed.
