Propelauth Rate Limits

Rate-limit posture for the PropelAuth backend APIs and end-user API key validation surface. PropelAuth does not publish explicit per-tenant request-per-second limits for the backend Integration API; production limits are tuned per customer. The end-user API key product enforces customer-configured per-key rate limits (with a 5,000,000-validation Advanced API Keys add-on) returned in the validation response payload.

Propelauth Rate Limits is the machine-readable rate-limit profile for PropelAuth on the APIs.io network, in the API Commons Rate Limits shape.

It captures 4 rate-limit definitions.

Limit state is signalled in the limit, remaining, reset, and retryAfter response headers, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes response codes documented for throttled and quotaExceeded.

Tagged areas include Authentication, Rate Limiting, API Keys, and B2B.
