Assistance Request: Implementing Microsoft Graph Email Change Notifications in Python

Question

I am writing to seek your assistance with a particular issue I am facing while trying to implement Microsoft Graph email change notifications in Python.

 

Firstly, let me assure you that I have carefully reviewed the Microsoft Graph documentation and watched video tutorials related to this topic. While I have successfully used Microsoft Graph to perform GET requests for emails, I am encountering challenges when it comes to setting up change notifications using subscriptions.

 

All the necessary permissions have been granted, and I have verified that my credentials are correct. Despite this, I have encountered some difficulties while attempting to implement the subscription feature in Python.

 

I have tried to adapt the documentation and video tutorial examples to my Python environment, but I am encountering some errors that I'm unable to resolve on my own. To give you a better understanding, I have attached screenshots of my code implementations along with the error messages.

Implementation Code 1:

Implementation Code 2:

Result:

Error creating subscription:

400 {"error":{"code":"InvalidRequest","message":"Subscription validation request failed. Notification endpoint must respond with 200 OK to validation request.","innerError":{"date":"2023-08-30T10:26:01","request-id":"eec3244b-8b21-47fe-a540-7de9d1feba8f","client-request-id":"eec3244b-8b21-47fe-a540-7de9d1feba8f"}}}

 

 

My primary goal is to receive email change notifications in real-time as emails are received. This real-time functionality is critical for my project, which is why I am eager to implement subscriptions.

 

I genuinely appreciate any assistance or guidance you can provide in resolving the issues I am facing. If there are any specific code examples or approaches in Python that you could recommend, it would be immensely helpful.

 

Thank you for taking the time to consider my request, and I am looking forward to your valuable guidance.
