Create "B2C User" with Microsoft Graph API

Question

We are trying to use B2C for our customer user login flow, but we have decided to use the ROPC flow for the basic login flow. As a result, we have to implement the user creation during registration ourselves.

We have been creating users with the Microsoft Graph API but it seems that we can only create users with the email domain "@mytenant.onmicrosoft.com" instead of being able to make a "B2C User" which can have an email with any domain.

Is there a way to create "B2C Users" with the Microsoft graph API? (See screenshot showing the "B2C User" template from the "create user" menu in the Azure portal)

Answer 1

Hey Roi,

Please check a similar thread and there is a code shared by the MSFT and also by the creator of the question and this should give you a good start - cannot-create-a-azure-b2c-user-via-ms-graph-api.html

Hope this helps.

Hi @Roei

Make sure you're using Azure AD-specific ROPC flow to get tokens.

Then call the /users endpoint to create a B2C user with social and local account identities:

POST https://graph.microsoft.com/v1.0/users  
Content-type: application/json  
  
{  
  "displayName": "John Smith",  
  "identities": [  
    {  
      "signInType": "userName",  
      "issuer": "contoso.onmicrosoft.com",  
      "issuerAssignedId": "johnsmith"  
    },  
    {  
      "signInType": "emailAddress",  
      "issuer": "contoso.onmicrosoft.com",  
      "issuerAssignedId": "jsmith@yahoo.com"  
    },  
    {  
      "signInType": "federated",  
      "issuer": "facebook.com",  
      "issuerAssignedId": "5eecb0cd"  
    }  
  ],  
  "passwordProfile" : {  
    "password": "password-value",  
    "forceChangePasswordNextSignIn": false  
  },  
  "passwordPolicies": "DisablePasswordExpiration"  
}
