Ensure entered api ID is int

Auth accepts these values in either order for building the model, but incorrectly assigns the vcode instead of ID to character models if entered incorrectly which can break certain functions.

This is an added layer of stupid-protection to make sure they put the API ID (a number) in the right field.
