Setting up the Paypal Payment Gateway in OpenCart 1.5

Paypal is one of the more popular online payment systems available on the internet. It enables you to accept and process credit card payments over the web. OpenCart allows you to integrate this option into the application. By default, OpenCart includes three Paypal options when OpenCart is installed.  However, only the UK version is enabled by default.  The following article shows you how to setup and configuret the Paypal Standard option in OpenCart 1.5.

Installing the Paypal Payment Gateway in OpenCart 1.5

1. Login to the Administrator Dashboard
2. Hover over the menu bar where it shows EXTENSIONS. Click on PAYMENTS when the drop-down menu appears.  You will see the following:
   
   
   
   There are three different versions of the Paypal extension, but only one of them is installed by default (the UK version).  If you want to find out more information about the differences in the available Paypal solutions, please go to: Paypal Payments Solutions Comparison Chart.
   
   
3. Click on the EDIT option in the right column for the PayPal Standard version and you will see the following:
   
   
   
   
   Note that the EMAIL field at the top of the screen is the only mandatory field in the configuration screen for the payment option. 
   
   The following table explains each option in the configuration options (the non-status items):
   
   

   Sandbox mode	Allows you to test the payment gateway
   Transaction method	This is either an authorization of a payment or the completion of a sale (Paypal can be just a payment authorizer, or also track and process the sale)
   Debug Mode	Provides more text to help troubleshoot issues
   Total	This is total amount that the order must meet before the payment method can be used
   Geo Zone	Indicates the zone that this payment method will be active
   Status	Indicates if the option is active and available for use
   Sort Order	Allows you to determine the order in which payment options will appear for the customer

   
   
   Go through each of these options and determine the setting by clicking on each item's drop down menu.
   
   
   
4. There are also 10 different order statuses that can be set in the configuration.  These options include the following selection in the drop-down menu:
   
   

   Each of these order states can be selected as the default selection status of the ten listed order statuses.  These definitions depend on the items you allow to be processed in your store (and if they are processed a particular way).  For example, it possible that you have a failed status and the default order status would be VOIDED.  This same process maybe different with other stores, but it depends on how you process these situations.

   
   Here is a quick breakdown of each field:
   
   

   Canceled Reversal	Canceled charge reversal
   Completed	Completed charge
   Denied	Charge denied
   Expired	Expired card- could not be charged
   Failed	Failed charge
   Pending	Awaiting processing of charge
   Processing	Charge in the middle of being processed
   Refunded	Amount being refunded to customer
   Reversed	Charge being reversed on order
   Voided	Charge voided - meaning it no longer exists

   
   Click on the drop-down to select the default status of each order field.
5. Once you have completed determining the status defaults and the other configuration options in Step 4, click on SAVE in the top right hand corner to complete the process and save the entries.
