Onboarding endpoints are rate limited to keep the platform stable for everyone. Build your integration to handle limits gracefully: space out bulk calls, and back off and retry when you're throttled.

Because creates carry an externalId, a retry after a throttled call is safe: PCE returns the resource it already created rather than duplicating it. See Idempotent Requests.

🚧

PENDING-PUBLISH

The exact rate limits (the per-key request budget and window), the response returned when a limit is exceeded, and any rate-limit response headers are not confirmable while the boarding spec is out of reference/. Confirm the rate-limiting contract against the published API Reference before publish.
