Paypal Recurring Payment Gateway Process:

PayPal Recurring Payments allows you to bill a buyer for a fixed amount of money on a fixed schedule. The buyer signs up for recurring payments during checkout from your site. Consider the following examples:

A buyer purchases a subscription to a magazine or newsletter from your site and agrees to pay a monthly fee. A buyer agrees to pay an Internet Service Provider a flat fee on a semi-annual basis to host a website. These examples represent payment transactions that reoccur periodically and are for a fixed amount. When you create recurring payments for a buyer, you create a recurring payments profile. The profile contains information about the recurring payments, including details for an optional trial period and a regular payment period. Each of these subscription periods contains information about the payment frequency and payment amounts, including shipping and tax, if applicable.

After a profile is created, PayPal automatically queues payments based on the billing start date, billing frequency, and billing amount, until the profile expires or is canceled by the merchant. The buyer can also cancel the recurring payment profile for profiles creating using Express Checkout.

Note that for profiles created using Express Checkout, the queued payments are funded using the normal funding source hierarchy within the buyer's PayPal account.

After the recurring payments profile is created, you can view recurring payments details or cancel the recurring payments profile from your PayPal account.You can also access recurring payments reports from the PayPal Business Overview page.
