Google Identity Platform Rate Limits

Google Identity Platform inherits Google Cloud's standard quota and rate-limit model. Limits are enforced per-project and per-API-method; defaults are documented in the Google Cloud Console quotas page and can be increased on request. Per-project request quotas apply to the Identity Toolkit API and related Identity Platform endpoints. SMS phone-auth has separate per-project verification quotas.

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

It captures 3 rate-limit definitions, measuring requests_per_minute, requests_per_day, and varies.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled, quotaExceeded, and serviceUnavailable.

Tagged areas include Rate Limiting, Authentication, Google Cloud, and Identity.

Policies

Backoff Strategy
Clients should implement exponential backoff with jitter when receiving 429 or 503, honoring the Retry-After header when present.
Quota raise via support
Default project quotas can be increased through the Google Cloud Console quota request flow; SLA-backed limits available on enterprise contracts.
Per-project scoping
Quotas are scoped to the Google Cloud project; multi-tenant deployments share the same project quota across tenants.
