Microsoft Bookings Graph API gives 500 Internal Server Error when canceling a booking appointment

Question

Hello,
Whenever I try to cancel a booking appointment, I receive a 500 Internal Server Error, but the appointment still gets cancelled.
The API is: POST /solutions/bookingBusinesses/{id}/appointments/{id}/cancel.

Error:

{

  "error": {

"code": "UnknownError",

"message": "",

"innerError": {

  "date": "2024-08-30T08:07:44",

  "request-id": "717fa982-983d-4e87-b589-05b64bd96fe7",

  "client-request-id": "717fa982-983d-4e87-b589-05b64bd96fe7"

}

  }

}

What could be the reason for this?

Hi @sonal khatri

It looks like this is an error thrown by the Graph server and is not directly related to your API request.

I recommend clicking the "feedback" button on the documentation to report this error or opening a support ticket and providing the returned request-id to the support team. They will help you troubleshoot the cause of the issue.

Hope this helps.

Hello sonal khatri,

Thank you for contacting Microsoft Support!

This error is a generic server-side error indicating that something unexpected happened on the server, but it doesn’t provide specific details about what went wrong.

Here are some potential reasons for this issue:

1. Server-Side Bugs: There might be bugs in the server code that handle the cancellation request, causing it to fail after completing the action.
2. Timeouts: If the server takes too long to process the request, it might timeout and return a 500 error.

I tried to cancel an appointment using Graph API and cancelled successfully. Please check below.

After following all the steps and still facing issue, I would recommend you to raise a support case with Microsoft Graph, a Support Engineer will be able to look into this issue and assist you better. You can raise support ticket from New support request - Microsoft Entra admin center or https://admin.microsoft.com/#/support/requests.

Hope this helps.
