The VeriSign® gateway consists of two Payflow product options (Payflow Link® and Payflow Pro®, respectively), and each product offering is based on the specific requirements associated with a merchant's business needs and technical expertise. Regardless of which product a merchant chooses, merchants are given access to the VeriSign Manager and the Payflow Recurring Billing module, which allow a merchant to charge a customer's credit card on a periodic and pre-determined basis. Below you will find a brief description of each VeriSign gateway product offering:
VeriSign Manager - is a Web-based tool that allows merchants to process manual transactions (i.e., sales, authorization only, voids and returns), to set up recurring billing, and complete administration functions, i.e., configure security settings, run reports, and download software and documentation. VeriSign Manager is included with both Payflow Link and Payflow Pro products.
Payflow Link - is a payment module designed to meet the needs of a merchant who does not require a complex solution with high-level functionality. Merchants who have an existing brochureware Web site and want to add the "Buy Now" button and accept credit cards online are encouraged to purchase Payflow Link. By adding the payment button, customers are sent to VeriSign's secure server to collect the credit card data. Payflow Link supports all major credit and check cards and purchasing card Level I (Level II is supported with the use of the tax calculation offered by a shopping cart vendor) and recurring billing.
Integration consists of incorporating hypertext markup language (HTML) to a new or existing Web site. Merchants may contact shopping cart vendors who have integrated the Payflow Link into their shopping cart and utilize the vendor's expertise and benefit from the functionality of the shopping cart.
Payflow Pro - is a scalable and fully customizable payment module that is recommended for merchants who have a secure server and who want direct control over the payment functionality. Payflow Pro involves the downloading of the software development kit (SDK) and implementation of applied programming interface (API). Payflow Pro supports all major credit and check cards, as well as automated clearing house (ACH) check service via TeleCheck®, purchasing card Levels I and II and recurring billing. Merchants may contact shopping cart vendors who have integrated the Payflow Pro into their shopping cart and utilize the vendor's expertise and benefit from the functionality of the shopping cart.
