Is there any way to create multiple Customers with the same email address? There’s no reason for my application to disallow two users with the same email address, and requiring unique email addresses would complicate my code.
If not, would you consider changing your API to allow it? FWIW, Stripe allows it.
EDIT: Alternatively, if I could not specify an email address–or a name, for that matter–when creating a Customer, that would be ideal.
