The InPost Pay widget offers coupling shopping baskets at stores with the InPost Mobile application. The frontend layer is delivered in the form of a JavaScript plug for embedding on the website, and of this documentation.

A correct integration requires providing a backend layer, html embedding of the plug, and control over the status of the front-end layer by providing the methods described below.

A list of methods to be implemented by the merchant's backend, in order to use the plug:

● iziGetBindingData
● iziGetIsBound
● iziGetOrderComplete
● iziBindingDelete
● iziCanBeBound
● iziAddToCart
● iziGetPayData
● iziMobileLink

function iziMobileLink() {
return Promise.resolve({

})
}

SPA

The plug has been developed for use with SPA applications. For the purpose of integrating the store with InPost Pay, the initiation of the Pay button must be handled within the app's life cycle.
Upon its first loading, the script automatically initiates all the instances of <inpost-izi-button/> W found in the code to initiate the widget after DOM update
use the method:

window.handleInpostIziButtons();

Below is an example for the ReactJs component:

import React, { useEffect } from "react";
import { useLocation } from "react-router-dom";

export...= ({ children }) => {
const location = useLocation();
useEffect(() => {
window.handleInpostIziButtons();
}, [location]);
return <>{children}</>;
};
