Rate Limits

Requests to specific Zendesk endpoints from the Zendesk mobile SDKs are rate limited.

A certain number of requests are allowed per minute depending on the endpoint.

Zendesk reserves the right to adjust the rate limit for given endpoints to provide a high quality of service for all clients. The following are the endpoints which are rate limited, the maximum number of requests per minute permitted for each endpoint, and how you can interact with these endpoints while using the SDK.

If the rate limit is exceeded, the API responds with a HTTP 429 Too Many Requests response code and a body that details the reason for the rate limiter kicking in. The response has a Retry-After header that tells you for how many seconds to wait before retrying. You should anticipate this in your mobile app for the smoothest possible experience. See Best practices for avoiding rate limiting.

If you anticipate a high volume of requests for a short period of time, Zendesk can enable an emergency limit of 10,000 requests per minute per requested endpoint. Please reach out to your account manager for more details.
