/sys/quotas/rate-limit

The /sys/quotas/rate-limit endpoint is used to create, edit and delete rate limit quotas.

Create or update a rate limit quota

This endpoint is used to create a rate limit quota with an identifier, name. A rate limit quota must include a rate value with an optional path that can either be a namespace or mount, and can optionally include a path suffix following the mount to restrict more specific API paths.

Method	Path
POST	/sys/quotas/rate-limit/:name

Parameters

• name (string: "") - The name of the quota.
• path (string: "") - Path of the mount to apply the quota.
• rate (float: 0.0) - The maximum number of requests in a given interval to be allowed by the quota rule. The rate must be positive.
• interval (string: "") - The duration to enforce rate limiting for (default "1s").
• block_interval (string: "") - If set, when a client reaches a rate limit threshold, the client will be prohibited from any further requests until after the 'block_interval' has elapsed.
• role (string: "") - If set on a quota where path is set to an auth mount with a concept of roles (such as /auth/approle/), this will make the quota restrict login requests to that mount that are made with the specified role. The request will fail if the auth mount does not have a concept of roles, or path is not an auth mount.
