Installing Stripe as a payment processor in CiviCRM 4.x
Folder structure is left in tact, but there is only 1 file and this is where it goes: Stripe.php in civicrm/CRM/Core/Payment/Stripe.php
Copy Stripe's PHP library folder 'stripe-php' to civicrm/packages/stripe-php You can get Stripe's PHP library here: https://github.com/stripe/stripe-php
Run the included SQL file "civicrm_stripe.sql" to: Insert Stripe into civicrm_payment_processor_type (makes it available as an option within CiviCRM's payment processor settings) Create table civicrm_stripe_customers Create table civicrm_stripe_plans Create table civicrm_stripe_subscriptions
