I am looking to setup a self-service signup portal for Azure AD B2B. Only information that's populated during the sign up is Email, Given Name and Surname.
I am looking to auto-fetch some other field like manager, job title, etc. Is there a way I can do this.
Created a user flow in Azure AD:
To populate the custom attributes during sign up, you can add custom attributes refer this MsDoc:
Go to Microsoft Entra ID -> External Identities -> Custom user attributes -> Add
Now go to User flows -> Select your User flow -> User attributes -> Select the custom attribute
I used Postman to test the same:
When I clicked on Create account, I got the custom attribute populated during sign in like below:
The user got created successfully like below:
