@muthuvel Unfortunately there is no Microsoft Graph API endpoint to get all tenants list and endpoint is available through Management Api's which you mentioned. Please provide this as a feedback at uservoice so that community can upvote and product team can plan to include in future releases.

So as of now we need to use the microsoft graph API & Management API for my app.

I am doing the OAuth 2.0 auth code grant for get the access token. Ref: https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-auth-code-flow

Data needed for my app:
1. Need to list out the tenants for that account
2. Get the list of users in each & every tenant

Questions:

So we need to do separate oauth flow for microsoft graph AP & Management API.

is it possible to use same access token for both endpoints ? Also please suggest to use the both APIs in same token.

Note: Try to use that access token for management API, It's not working. Pls check the reference.

@muthuvel No, it won't work as bearer token is always valid of a single API and you may need to use either of the below two approaches as mentioned in this SO post -

Get two tokens

Use the same app id for both APIs
