What are the parameters which PAYPAL and 2Checkout sends for IPN in case for buy without subscription, subscription first payment, subscription not first payment and refund.
I need understand the workflow so I can implement correct. I already checked the documentation and I already build the form for payment with/without subscription.
The full parameter list is located https://www.2checkout.com/documentation/notifications/order-created there for a non-recurring sale, use the sidebar nav on the left to find the recurring INS messages. Each INS link has a description as to when the event is triggered:
e.g. Order creation is a new order placed online by a buyer. You may want to automate inventory management, fulfillment or setup of login credentials based on this message.
Recurring order creation is a special case of order creation; if any item ordered is recurring, the recurring parameter will be set to 1, otherwise, it will be set to 0.
Please note the initial installment billed often differs in price from the installments due to startup fees.
Order Created is an invoice level message; it will be sent once for each new sale and will contain information about all items ordered.
