HTTP Response 401 while trying to subscribe Outlook Events - Java

I am using Outlook Rest API to subscribe events. However, I get error code 401 although I include the access token. I get the access token following https://learn.microsoft.com/en-us/outlook/rest/java-tutorial this tutorial. And my payload is like the following:

{

"@odata.type":"#Microsoft.OutlookServices.PushSubscription",

"Resource":"https://outlook.office.com/api/v2.0/me/events",

"NotificationURL":URL,

"ChangeType":"Created"

}

with the header:

authorization: Bearer + access token which I get from the tutorial.

Something like this)

Why do I get 401?

Thank you.

Solution

  • A 401 means that your token isn't valid for what you're trying to do. It could be expired, invalid, etc. Typically the body of the response gives more detail on the reason of the 401.

    I'd recommend going to https://oauthplay.azurewebsites.net/ and playing with the notifications API there to see how it all works.
