Create user with other mail provider in Azure AD B2C (gmail,etc...)

Question

I used Microsoft Graph API PHP SDK to add user in my Azure Active Directory B2C. I managed to create users with a userPrincipalName like [email protected].

I wasn't able to add users with a GMail address such as [email protected].

I tried to add the signInNames collection but I got the following response:

Fatal error: Uncaught GuzzleHttp\Exception\ClientException: Client error:
POST https://graph.microsoft.com/v1.0/users resulted in a 400 Bad Request
response: 
   { "error": { 
       "code": "Request_BadRequest", 
       "message": "Invalid property 'signInNames'.", 
       "innerError": (truncated...)

Here is my JSON request body :

{
    "accountEnabled": true,
    "displayName": "John Doe",
    "userPrincipalName": "[email protected]",
    "creationType": "LocalAccount",  
    "passwordProfile" : {
        "forceChangePasswordNextSignIn": true,
        "password": "P@!ssWor?D"
    },
    "signInNames": [
        {
            "type": "emailAddress",
            "value": "[email protected]"
        }
     ]
}

In case if someone will still have the same problem, in MS Graph Api you can use "identities" instead of "signInNames" and your JSON will look like

{
   "accountEnabled":true,
   "displayName":"John Doe",
   "userPrincipalName":"[email protected]",
   "creationType":"LocalAccount",
   "passwordProfile":{
      "forceChangePasswordNextSignIn":true,
      "password":"P@!ssWor?D"
   },
   "identities":[
      {
         "signInType":"emailAddress",
         "issuer":"<your tenant domain name>",
         "issuerAssignedId":"[email protected]"
      }
   ]
}
