Rate limits

Limits protect the platform and your account. They're generous for normal traffic and you can request higher ceilings for production.

When you're limited

  • You get 429 with code: rate_limited and a Retry-After header (seconds).

  • Honour Retry-After; add jitter so retries don't thunder back at once.

  • Cache your access token (don't fetch one per request) — the single biggest cause of token-endpoint limiting.

Need more headroom?

Request a higher ceiling during go-live from the Developer portal — tell us your expected peak throughput.
