PayPal is an Internet business which allows the transfer of money between email users, avoiding traditional paper methods such as cheques and money orders. PayPal also performs payment processing for e-commerce vendors, auction sites, and other corporate users, for which they charge a fee. It is a web-based service that enables Internet users to send and receive payments electronically. To open a PayPal account, users register and provide their credit card details. When they decide to make a transaction via Pay Pal, their card is charged for the transfer. It is widely used and accepted throughout the world.

To configure PayPal from the top, navigate to Configurations >> Payment Gateways. Configuration process includes the following.

Configuring PayPal

To configure PayPal specify the followings.

• PayPal Email Address: This is the PayPal merchant account email address.
  
• Command Type: Type command type here. Depending on these command types and payment modes, PayPal user interface is shown.
  
  
  For Example - If your command type is simple payment type then just an optional description field is displayed on the PayPal payment form. If command type is purchase request then the PayPal payment form asks for item details also. 
• Amount Multiplier: This multiplies the invoice amount by the multiplier. For e.g. if multiplier is 2 and the invoice amount is 10, the amount is multiplied by the multiplier 10 x 2 = 20. If multiplier is given then amount will be multiplied to it before sending to the gateway. Default value is “1” which means amount will be sent as it is to the gateway.
• Minimum Charge: Payment gateways charge fee for every transaction. Sometimes it’s not feasible to pay extra fee for every small transaction. To avoid these extra charges, the host can specify a minimum charge. While paying customers cannot specify an amount less than this minimum charge.
