Use Access Token for Graph API in AAD B2C

The access token that the app receives after successful authentication, can we use the same token for invoking GRAPH APIs for /me.

I tried to use the access token that I received in POSTMAN for /me but got an invalid token error. If I explicitly generate the token in POSTMAN, I am able to use it for /me.

What am I doing wrong here?enter image description here!

Solution

  • I tested it.The access token you get after successful authentication of the app you use should be b2c, while b2c cannot be used to request a graph endpoint. See reference from Azure AD B2C auth code flow. enter image description here

    enter image description here You can successfully request /me endpoint with the explicitly generated access token in POSTMAN because you are using an access token from Azure AD auth code flow.
