Common questions about the REST API: authentication, rate limits, webhooks, and integrations.

What rate limits apply to the API?

The default rate limit is 2 requests per second per account, applied across all endpoints (not per-endpoint).

If you exceed the limit, requests return 429 Too Many Requests. Respect the Retry-After response header before retrying. The API also sends:

  • X-RateLimit-Limit — the maximum requests in the current window.
  • X-RateLimit-Remaining — the requests left in the current window.

Need higher limits?

Pro and Business customers can request elevated rate limits — contact us with your expected request volume and we'll set it up.
