Additionally, some endpoints have special rate limits or account-level locks to prevent abuse of bulk endpoints. ### Per-api-key limits You are limited to 2 requests per second per API key. ## Per-account limits You are limited to your plan's associated rate limit, broken up into hourly buckets. As of August 2024: * Basic - 1000/day in buckets of 41/hour * Premium - 100 000/day in buckets of 4 166/hour * Enterprise - 300 000/day in buckets of 12 500/hour * Enterprise 2X (Paid) in buckets of 25 000/hour * Enterprise 4X (Paid) in buckets of 50 000/hour ## Endpoint limits It is rare, but certain endpoints have custom rate limits, you may need to dynamically wait in these cases. ## Endpoint locks Some endpoints have locks that prevent multiple requests from being processed simultaneously by API for the entire account. These are typically actions like bulk\_reconcile, bulk\_delete, or bulk\_receive. You should queue and wait for each request to finish or implement an exponential fallback algorithm and resubmit your requests until you receive a 200, 202, or 203 status code. ## Dynamically waiting for rate limit resets. If your 429 error contains an error object, you can wait `error.data.wait_seconds` seconds for your rate limit bucket to reset. ``` { "error": { "message": "Rate limited. You are allowed etc...", data: { "wait_seconds": 8 } } } ``` This number can be up to an hour or longer. Do not arbitrarily sleep your program in response to this error.
