Rate limits

Each API key can make 600 requests per minute. Every response tells you where you stand.

Limits

Requests are counted per API key in one-minute windows: up to 600 requests per minute per key. Keys don’t share a budget, so a busy sync can’t slow down your other integrations — another reason to give each integration its own key.

Rate-limit headers

Header	Meaning
`X-RateLimit-Limit`	Requests allowed per window (600).
`X-RateLimit-Remaining`	Requests left in the current window.
`X-RateLimit-Reset`	When the window resets, in Unix seconds.
`Retry-After`	On `429` responses: seconds to wait before retrying.

When you hit the limit

Requests over the limit answer 429 Too Many Requests and do nothing:

429 Too Many Requests

{  "error": {    "retryAfter": 12,    "code": "rate_limited",    "message": "Too many requests. Try again shortly."  }}

Wait Retry-After seconds, then retry. For bulk jobs, slow down before you hit the limit by watching X-RateLimit-Remaining, and prefer webhooks to polling.
