How to Use Sharepoint V2.0 API with access token generated without azure portal portal

Question

We want to access sharpoint V2 API using Postman (https://{tenant-name}.sharepoint.com/_api/v2.0/sites).

We don't have access to add application using azure portal. So we are generating access token by method used for V1.0 . Our access token is working for V1 API but giving authentication issue with V2.0 API. Is it possible to use V2.0 API with token generated by given below method.

Step 1: Go to the Register App Add-in page using the URL and create client id and secret id https://one.aon.net/sites/<sitename>/_layouts/15/appregnew.aspx

Step2*:** Grant permission using* https://one.aon.net/sites/<sitename>/_layouts/15/appinv.aspx

Step3*: Generate access token using POST*** https://accounts.accesscontrol.windows.net/TenantId/tokens/OAuth/2

Generated token working fine for V1.0 API. Kindly advice can we access V2.0 API using this token or Azure portal is mandatory here to add application

Hi @Ankur Mittal

You can still use the SharePoint app only to access V2.0 API. You can refer to the following steps to get access token

Then you can use the following api to get the data from SharePoint
