Zendesk Rate Limits

Zendesk publishes per-plan account-wide API rate limits in requests per minute, with additional endpoint-specific limits, a job-queue cap, and an account-wide spike-protection ceiling. Limits scale with the Suite / Support tier; the High Volume API add-on lifts qualifying plans to 2,500 req/min.

Zendesk Rate Limits is the machine-readable rate-limit profile for Zendesk on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 17 rate-limit definitions, measuring requests_per_minute and concurrent_requests.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Customer Service, Help Center, Ticketing, CRM, and Rate Limiting.

Policies

429 + Retry-After
When the limit is exceeded the API returns 429 Too Many Requests with a Retry-After header indicating how many seconds to wait before retrying.
X-Rate-Limit header
Responses include an X-Rate-Limit header reflecting the account's current per-minute ceiling (e.g. X-Rate-Limit: 700).
Plan-tier scoping
Limits are account-wide and scale with the Suite / Support plan tier. Endpoint-specific limits apply on top of the per-plan ceiling.
High Volume API uplift
The High Volume API add-on lifts qualifying plans to 2,500 req/min and also boosts incremental-exports throughput.
