Hi - @aleung , Thanks for reply. I tried that, but not working. I am kind of stuck.
I have followed below steps -
- I have Register as a Add-In in SharePoint.
- I have granted permission to the Add-In.
- Retrieved the Tenant ID through Postman (Get method).
- Tried to generate the access token using Postman, but getting below error -
“error”: “invalid_request”,
“error_description”: “AADSTS90002: Tenant f12a3f9e-37a5-4551-80f1-e93a20857154 not found. This may happen if there are no active subscriptions for the tenant. Check with your subscription administrator.\r\nTrace ID: 2d277d04-473c-4a21-aa5b-b3a66b740100\r\nCorrelation ID: 921acc97-f0cd-48d3-ae17-1cf88461c6d6\r\nTimestamp: 2018-03-01 10:02:30Z”,
