How to know if my notifications-delivery-webhooks are throttled?

There are conditions that Microsoft Graph throttles notifications sent to endpoints that become slow or unresponsive. It may include dropping notifications in a way that they can't be recovered.

How can I find out if my endpoint has been throttled?

Hi @Tsai Yunda ,

Thanks for reaching out to Microsoft!

Microsoft Graph change notifications service receives a 2xx class code from your endpoint, the notification is considered sent.

Please check the HTTP status codes returned by your endpoint. If your endpoint frequently returns 5xx status codes or takes longer than 10 seconds to respond, it may be throttled.

Microsoft Graph includes retry headers in its responses when throttling occurs. Look for these headers in the responses to understand the retry logic and intervals.
