The Create User API allows you to create a new user in the system. Upon successful creation, the API returns an
user_external_id, which can be used to initiate the Sunlight Connect SDK.
As a general approach, Sunlight doesn’t need to know any information about your users, that’s why Sunlight expects you to store the
user_external_id on your side and attach it to your own user base. If you want to have the same user entity performing multiple actions within the Sunlight SDK, we expect you to pass us the same
user_external_id as part of the SDK Initialization.
