Which Endpoint/s?

Hey @chamathpali,

Are you submitting other requests to any of the other Users endpoints, or is this the only endpoint you’re hitting? Similarly, are you trying to send several concurrent requests in a short amount of time? This can cause this error message as well.

Let me know—thanks,
Will
