A User Intent manages the lifecycle of the creation of a User, before that User has been fully created. This endpoint retrieves the User Intent details.

Note that the user_id will be returned in the payload if the UserIntent has been successfully converted to a User. Also note that a UserIntent does not need to have an Approved Status to be converted to a User.
