A [429 Too Many Requests] (RFC 6585: Additional HTTP Status Codes) error will be issued when you have exceeded the rate limit for a given API endpoint.
On each request, the Management API will return HTTP Response Headers with the relevant information for the rate limit status:
- X-RateLimit-Limit: The maximum number of requests available in the current time frame.
- X-RateLimit-Remaining: The number of remaining requests in the current time frame.
- X-RateLimit-Reset: A UNIX timestamp of the expected time when the rate limit will reset.
Please check Rate Limit Policy for more information about the rate limits and the endpoints to which they apply.
