Notes on using Microsoft Graph SDK to manage users in an Azure AD B2C tenant.

I recently worked on migration users’ accounts in an existing SQL database to azure AD B2C. I found some helpful articles from Microsoft that document different migration approaches and offer example codes on using Microsoft Graph SDK to manage the users. You can find the links to these articles and sample projects in the References section.

For the most part, I did not have much troubles with the basic CRUD operations. However, I had a bit of difficulties working with custom attributes and retrieving a user by email. In this post, I’m going to share some tips and caveats I learned. In particular, I’ll discuss:

• The Microsoft Graph API permissions you need to manage the users.
• Caveat on UserPrincipalName attribute and retrieving a user by email.
• Setting and retrieving custom attributes in Azure ADB2C.
