Completion of the module LiqPay for OpenCart

You need to configure the plugin for liqpay store in opencart

We need to implement the possibility of payment through liqpay in the store on opencart version 1.5.4.1.

At the moment we have a plugin https://github.com/liqpay/plugin-opencart . Support liqpay said that the plugins are no longer supported and no longer developed. Therefore, it is recommended to use the API https://www.liqpay.ua/documentation/uk/api/aquiring/checkout/doc . In the plugin, implemented part of the code.

We want the options refinement of an existing plugin or install a working solution.
