Google Workspace Rate Limits

Google Workspace REST APIs are governed by Google Cloud per-project quotas. Each Workspace API publishes its own service-specific quotas (visible in the Google Cloud Console > IAM > Quotas page) typically expressed as queries per minute per project, queries per minute per user, and per-user-per-second limits. Examples include Admin SDK Reports at 2,400 QPM per user per project with a separate filter-query limit of 250 per minute / 15,000 per hour. Quotas can be raised via Google Cloud support.

Google Workspace Rate Limits is the machine-readable rate-limit profile for Google Workspace on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 7 rate-limit definitions, measuring requests_per_minute, varies, requests_per_second, and records_per_page.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled, quotaExceeded, and serviceUnavailable.

Tagged areas include Rate Limiting, Calendar, Collaboration, Email, and Productivity.

Policies

Backoff Strategy
Use exponential backoff with jitter on 429 / 503; respect Retry-After when present.
Quota raise via support
Default project-level quotas can be increased through the Google Cloud Console quota request flow.
Per-user vs per-project scoping
Most Workspace APIs enforce both per-authenticated-user and per-project quotas; either ceiling can throttle.
Use of audit log exports
For high-volume Reports API consumers, Google recommends BigQuery audit log export instead of polling activities.list.
