Create External B2c Users With Microsoft Graph: Password And Email Method

Creating external B2C users with Microsoft Graph using the password and email method can be a bit tricky if you’re not familiar with the ins and outs of the process. But don’t worry! This guide will help you step-by-step, ensuring that you can effectively manage external users in your applications.

Understanding External B2C Users

Before diving into the creation process, it's crucial to understand what external B2C (Business to Consumer) users are. These users typically represent clients or consumers who interact with your application but are not part of your organizational Azure Active Directory (Azure AD).

With Microsoft Graph, you can easily manage and create these users, allowing them to authenticate through various methods, including email and password.

Prerequisites

1. Azure AD B2C Tenant: Ensure you have an Azure AD B2C tenant set up.
2. Microsoft Graph Permissions: You’ll need appropriate permissions (like User.ReadWrite.All) to create users.
3. Graph Explorer or SDK: Use Microsoft Graph Explorer for manual testing or the SDK for programmatic access.

Steps to Create External B2C Users

1. Set Up the Request

To create an external user using the password and email method, you will need to construct your request correctly.

Here's the typical format of the JSON body you need to send:

{
  "accountEnabled": true,
  "displayName": "John Doe",
  "mailNickname": "johndoe",
  "userPrincipalName": "johndoe@yourtenant.onmicrosoft.com",
  "passwordProfile": {
    "forceChangePasswordNextSignIn": false,
    "password": "YourP@ssword123"
  }
}

2. Make the API Call

Using Microsoft Graph, you will be making a POST request to the /users endpoint. Here's how it generally looks:

• Endpoint: POST https://graph.microsoft.com/v1.0/users
• Headers:
  • Authorization: Bearer {token}
  • Content-Type: application/json

You can use tools like Postman, or if you're in a coding environment, use libraries like requests in Python or HttpClient in .NET to perform the API call.

Example in Postman

1. Open Postman and set the method to POST.
2. Enter the URL: https://graph.microsoft.com/v1.0/users.
3. Set your headers with the authorization bearer token and content type.
4. Paste the JSON body into the body section of the request.
5. Click "Send" and check the response.

3. Handling the Response

If the creation is successful, you’ll receive a response with a 201 status code and the details of the created user. If there's an error, the response will help you troubleshoot the issue.

Common Mistakes to Avoid

• Incorrect JSON Format: Ensure your JSON is properly structured and validated.
• Authorization Issues: Make sure you have valid authentication and necessary permissions.
• Using an Already Existing User Principal Name: Each user must have a unique userPrincipalName.

Troubleshooting Tips

If you encounter issues during the user creation process, here are some common troubleshooting steps:

• Check Azure AD B2C Settings: Ensure that your Azure AD B2C configuration is properly set up to allow the creation of users.
• Examine API Permissions: Review and confirm that your app has the required API permissions.
• Read Error Messages: Microsoft Graph API returns error messages that provide hints about what went wrong. Use this information for debugging.
