Hi All,

I am new to B2C and AD, please excuse if this is a lame question.

I am calling a REST API to create a record in the third-party system during user signup using custom policy. This part works fine without any issue and I am getting the record ID as output claim. Now I need to to set this ID in a string attribute the AD user record. How can I achieve this?

I understand that REST API call happens before user creation in the AD, so I have the ID when the user record is created in AD.

Many thanks

    You have to declare the claim in a PersistedClaim element of the Azure AD technical profile (usually used as a validation technical profile) being called by your REST API. E.G. AAD-UserWriteProfileUsingObjectId
