Download Free Comersus Cart with PayPal

Comersus is pleased to launch this section with detailed information on the options available to use PayPal.

The current version of Comersus Cart supports both PayPal Standard and Web Site Payments Pro.

PayPal Standard (included with Free Distribution)

This easy setup enables merchants to receive payments with PayPal funds or credit card, at a convenient discount rate. PayPal Standard is included in the Free Distribution of Comersus, so any merchant may add this payment option. When PayPal Standard is configured, the customer is redirected to PayPal to place payment. After payment is received, PayPal servers connect to Comersus securely to inform payment. Then the merchant can distribute digital goods, update stock and sales statistics, and maintain synchronized order and payment records.

Instructions to configure PayPal
1. If you don't have a PayPal account, sign up here...
2. After installing Comersus, enter your PayPal e-mail during the execution of the Wizard

3. To configure optional IPN (instant payment notification to update order status and distribute digital goods)
a. Log into your PayPal account
b. Go to the Profile subtab
c. Click on the Instant Payment Notification Preferences link in the Selling Preferences column
d. Click on Edit
e. Check the box and enter http://www.yourdomain.com/comersus/store/comersus_gatewayPayPalSilentResponse.asp to receive your IPN notifications
f. Click on Save

PayPal Express Checkout

This option allows customers to check out at PayPal rather than your Comersus store. After checkout at PayPal, the order and client data are transferred to Comersus.

Express Checkout is very convenient since it provides customers with a single and familiar checkout platform. In addition, first-time customers may feel more comfortable entering their information within PayPal. After implementing Express Checkout, the PayPal checkout button is displayed on the shopping cart page, below the store's regular checkout button. There, customers can choose one or the other checkout method.

Instructions
1. If you don't have a Verified PayPal Business Account, sign up here...
2. Go to Profile, Account Information, API Access, Request API Credentials, select API Signature Radio Button, and copy user, password and signature
3. Open the PayPal Wizard within BackOffice Plus and copy the above data
4. Select Express Checkout

PayPal Web Site Payments Pro

This option enables merchants to accept credit card payments without customers leaving their website. This option also has competitive discount rates and many additional features such as issuing refunds and approving payments from BackOffice Plus. In addition to the Direct Pay credit card payment method, you can also use the popular PayPal Express Checkout system. Under this system, customers select products at your store but check out at PayPal. This is a very convenient option with added security, integrity and privacy for customer data.

The Comersus implementation of PayPal Web Site Payments Pro uses the latest VPN and API Signature specifications. This spares merchants the IT and consulting complexities of installing and assigning permissions to personal certificates.

Instructions
1. If you don't have a Verified PayPal Business Account, sign up here...
2. Go to Profile, Account Information, API Access, Request API Credentials, select API Signature Radio Button, and copy user, password and signature
3. Open the PayPal Wizard within BackOffice Plus and copy the above data
4. Select Express Checkout or Express Checkout plus Direct Pay

You are done! Comersus will configure internally all parameters necessary to add PayPal integration.

Note regarding SandBox

In order to implement payments in a testing environment you should create at least two accounts (one to send payments and a second one to receive them) in the PayPal SandBox. Instead of loading production data in Comersus, load SandBox account data. Finally, select Demo Mode within Comersus. Then you will be able to test the complete purchasing procedure and experience the customer's perspective of your store, risk-free.

Sign up for PayPal and start accepting credit card payments instantly.
