In our buddy service you are not restricted to create users with us.
If you want to check that a user exists before sending a friend request you must user our userService. This module allows you to create App Users. It enables User registration, retrieval, state management e.g., Lock, Delete, Authentication and more. Along with User management, the library provides API’s for persistent Session Management.
Currently we are not provide buddy management in our console, if you want to delete your friend request you can use our API reject_friend_request
