Data Center Rate Limiting

Customizable rate limiting is available to Data Center customers only. For Cloud customers, rate limiting is managed by Atlassian.

Rate limiting controls the number of requests users can make to the API within a specified time frame on a node. Enabling this feature helps prevent excessive usage and ensures fair access to the API for all users in your environment.

Rate limit refill time Defaults to 1 second	Refers to the time interval used to measure the rate limit refill in conjunction with the refill rate. When users reach or exceed the rate limit, they need to wait until the refill time elapses. During this waiting period, users won’t be able to make additional requests.

FAQs

How do I know if the rate limit has been reached?

While the Dashboard is loading, the error message below will appear on Custom Charts gadgets.

Why would I enable rate limiting?

If you have a large Jira instance, or, are using complex JQL queries on your Dashboards, and you are having performance issues, rate limiting is recommended.

Can I impose limits on specific users only?

No, it is not possible to limit only specific users. If an account is a heavy user of the API, they will be limited. As rate-limiting is a per-user limit, only those who are heavy users will be impacted.
