OpenCart Plugin

Objective

We want to install and configure the PhonePe plugin in the Opencart environment which is
developed in PHP language and we have also used some functionality of curl in order to call the
“/pg/v1/pay” API through HTTP requests

Note: We will first share the test credentials with the merchant so that they can perform the
transactions in the test environment. For this, the merchant needs to select “PreProd Environment”
in the “settings” option and the merchant can pay using the PhonePe PreProd app. After checking
all the scenarios, we will give sign-off to the merchant and the merchant can go live with the prod
credentials.
