+# Rate limits on pipeline creation **(FREE SELF)**
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/362475) in GitLab 15.0.
+
+You can set a limit so that users and processes can't request more than a certain number of pipelines each minute. This limit can help save resources and improve stability.
+
+For example, if you set a limit of `10`, and `11` requests are sent to the [trigger API](../../../ci/triggers/) within one minute,
+the eleventh request is blocked. Access to the endpoint is allowed again after one minute.
+
+This limit is:
+
+- Applied independently per project, user, and commit.
+- Not applied per IP address.
+- Disabled by default.
+
+Requests that exceed the limit are logged in the `application_json.log` file.
