Census Ci Rate Limits

The Census Management API applies per-workspace request rate limiting on the Bearer-token-authenticated endpoints (sources, destinations, syncs, sync runs, models/datasets, connectors, segments). Requests that exceed the limit are rejected with HTTP 429. Specific per-endpoint request-per-minute values are not published as fixed public numbers and are not reconciled in this artifact.

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

It captures 3 rate-limit definitions, measuring requests and records.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Reverse ETL, Data Activation, Syncs, Rate Limiting, and Quotas.
