Azure AD B2C: Add Custom Field when creating a User

Question

I added a custom field, which is one of my internal identifiers.

Now, when I create users, I would like to set the value of that custom field by myself.

I don't see an option to do it. How can I proceed?

Hello @AIMus-3998 ,

You could achieve this via following graph API for Azure B2C

1. identityUserFlowAttribute
2. Update or delete directory extension properties

Here are the steps you could follow:

• Validate your custom attribute: GET https://graph.microsoft.com/v1.0/identity/userFlowAttributes/{id}

• Validate your user: GET https://graph.microsoft.com/beta/users?$select=id,displayName,extension\_{attribute id}
• Patch the user properties with custom attribute value: PATCH https://graph.microsoft.com/v1.0/users/ {user-id}
  {
  "extension_{attribute id}": "{value}",
  }

• Validate the user again to see if the extension property value has been updated or not:
  https://graph.microsoft.com/beta/users/{User-id}

Please do let me know if you have any queries by posting them in the comments section.
