Google Tag Manager Rate Limits

Published request quotas for the Google Tag Manager API v2. Quotas are enforced per Google Cloud project (not per API key or per user), across a rolling window, and exhaustion is signalled with HTTP 403 and a reason code in the Google JSON error envelope - not the more common HTTP 429.

Google Tag Manager Rate Limits is the rate-limit profile for Google Tag Manager on the APIs.io network — every limit transcribed verbatim from the provider’s own documentation on 2026-08-13.

It captures 2 rate-limit definitions, including Requests per project per day — 10,000 requests per project per day; Queries per second per project — 0.25 queries per second (QPS) per project.

Limit state is signalled in the limit, remaining, reset, and retryAfter response headers, and an exhausted limit returns HTTP 403.

The profile also includes response codes documented for throttled, throttled_note, and retryable_reasons.

Tagged areas include Analytics, Conversion Tracking, Marketing, Tag Management, and Tracking.
