remove_cards_on_stripe_customers.rb

# Michael Bianco <mike@suitesync.io>
# Description: An example script demonstrating how to remove customer cards. This
#              is helpful for keeping a card around temporarily for reauthorizing a
#              expired card authorization. More information:
#              https://dashboard.suitesync.io/docs/auth-fulfill-capture#id-like-to-create-an-authorization-for-more-than-7-
