You can buy Premium Modules for Your OpenCart Store. But here I just give you a simple way of integrating Zaakpay With your OpenCart Online store. First and before going to initiate the tutorials Please feel free to donate some money for my time to prepare this tutorial to you.

And now, you are going to integrate Zaakpay to your opencart store. The very first step is to creating required files for your our new payment module.

/admin/controller/payment/zaakpay.php

/admin/language/english/payment/zaakpay.php

/admin/view/template/payment/zaakpay.tpl

/catalog/controller/payment/zaakpay.php

/catalog/controller/common/zaakpay.php

/catalog/model/payment/zaakpay.php

/catalog/language/english/payment/zaakpay.php

/catalog/language/english/common/zaakpay.php

/catalog/view/theme/default/template/payment/zaakpay.tpl

/catalog/view/theme/default/template/common/zaakpay.tpl

These are all the necessary files for our payment gateway integration. Than as-usual start writing of coding’s one by one.

First we are going to write admin sections, than followed to catalog(Front-End ) section. Open controller class file
