Take Payment via Stripe for Appointment

[kchapple]

0- Install PHP stripe integration via composer. https://stripe.com/docs/libraries#php-library

1- Upon /register, when we create a new patient in the EHR, we need to also create a Strip customer, using the token passed extension to the Patient resource. https://stripe.com/docs/api/php#create_customer

2- We need to store the Stripe Customer ID in the patient_data table (so we can make charges and retrieve customers)

3- Upon GET request to Patient, we need to retrieve Card-Holder, last-4-digits of card, and exp date (month and year.) The card details should come from the "master" patient. There is a goup_id field in patient_data that is the pid of the "master" patient. We should get the Stripe customer ID from that patient and retrieve Stripe Customer data. https://stripe.com/docs/api/php#retrieve_customer

4- Upon clicking a "charge" button (yet to be specified) the system will apply a charge to the card on file. https://stripe.com/docs/api/php#create_charge
