Hi @Mukesh Kumar Yadav

You just want external users to log in to your B2C application for authentication and don't want to register them into the tenant?

Okay, was this external user created via "Create local or social user"? Do you want to use this user to call the graph API or your customized Web API? https://learn.microsoft.com/en-us/graph/api/user-post-users?view=graph-rest-1.0&tabs=http#example-2-create-a-user-with-social-and-local-account-identities

You can get it directly using the user id. For example:

/users/{user id}

Hi @Mukesh Kumar Yadav

Try calling the following API to get the local user:

https://graph.microsoft.com/v1.0/users?$filter=identities/any(a:c/issuerAssignedId eq '{user name}' and a/issuer eq '{tenant name}.onmicrosoft.com')

Hope this helps.
