What happens if I exceed my plan’s REST API daily request limit?

If your plan is subject to the hard limit on REST API, then you will get an HTTP 429 [1] response status code along with an error message if you exceed your daily limit. For the soft-limited agreements if you exceed your limit on a regular basis, then we will contact you and kindly ask you to upgrade.

You may check our Subscription Management API for proper tracking of your usage. [2]
