Authorization and Token endpoints in Sharepoint

Question

Hi Guys,
I am trying to authenticate to sharepoint rest api. These are the steps I did.

1. Created app registration in azure active directory and I gave permission to Site.ReadAll, Site.ManageAll .etc
2. Generated client credentials, and copied client ID,
3. Send the token request to the following url
   https://login.microsoftonline.com/\*\*\*\*\*-***-***-\*\*/oauth2/v2.0/token
   with the scope
   https://**********.sharepoint.com/.default
4. I got the token and use that as bearer token, and send the request to get a sharepoint resource, And it fails with 401 unauthorized.

Anyone has any idea why it is failing. If you can point me to a right direction, that will great. I appreciate your help.

Thanks

Hi @codeninja12 ,
You need to create self signed certificate if you are using azure app. You can refer to the document to upload certificate. So I will recommend you to grant access using SharePoint App-Only. grant permission to your client id by steps and then you can get bearer token by https://login.microsoftonline.com/---/oauth2/v2.0/token
