Embedded flow

Overview

Embedded components for checkout refer to a collection of ready-made user interface elements designed to facilitate the construction of your checkout process..

Usage example

Set up the server:

  • Install the packages (axios, express in example code) and import them in your code.
npm install axios express
  • Add an endpoint on your server that creates a checkout. Setup checkout parameters and set success_url and failure_url for redirect customer. Create index.js file with code bellow:
const express = require("express");
const axios = require("axios");
const PORT = 5000;
const YOUR_DOMAIN = `http://localhost:${PORT}`;
const API_KEY = "X-api-key";
const app = express();
app.use(express.static("public"));

app.post("/checkout", async (req, res) => {
  const result = await axios.post(
    "https://api.sandbox.upgate.com/v1/checkout",
    {
      payment_data: {
        ui_mode: "EMBEDDED",
        type: "SALE",
        methods: ["CARD", "GIROPAY", "MBWAY"],
        amount: "20.03",
        currency_code: "EUR",
      },
      customer: {
        merchant_customer_id: "test",
      },
      callback: {
        success_url: `${YOUR_DOMAIN}/index.html?success=true`,
        failure_url: `${YOUR_DOMAIN}/index.html`,
      },
      products: [
        {
          type: "SALE",
          price: 55,
          name: "Test product name for SALE",
          description: "Test product description for SALE",
        },
      ],
    },
    {
      headers: {
        "X-Api-Key": API_KEY,
        "Content-Type": "application/json",
      },
    }
  );
  res.json({ url: result.data.session.redirect_url });
});
app.listen(PORT, () => console.log(`Running on port ${YOUR_DOMAIN}`));

Build a checkout page on the client

  • Load Upgate.js

    Leverage Upgate.js to maintain PCI compliance by ensuring that payment information is transmitted directly to Upgate without accessing your server. To stay compliant, consistently load Upgate.js from js.upgate.com. Avoid incorporating the script into a bundle or hosting it independently. Create ./public folder and create index.html with code below:
<html lang="en">
  <head>
    <script type="module" src="https://js.upgate.com/upgate.js"></script>
    <script type="module" src="/main.js"></script>
    <style>
      body {
        min-height: 100vh;
        justify-content: center;
        width: 350px;
        margin: 0 auto;
        display: flex;
        flex-direction: column;
        gap: 32px;
      }
    </style>
  </head>
  <body>
    <div id="payment"></div>
    <button id="buy" onclick="submit()">Buy</button>
  </body>
</html>

  • Mount Checkout element

    Upon loading your checkout page, promptly initiate a request to the endpoint on your server to generate a new Checkout. The URL provided by your endpoint is utilized for rendering the embedded checkout element. Create a CheckoutElement and mount it to the element <div id="payment"> in your payment form. This incorporates an iframe containing a dynamic form that showcases configured payment method types available from the Checkout, enabling your customer to choose a payment method. The form autonomously gathers the relevant payment details for the chosen payment method type. Create main.js file with code below in ./public folder:
let upgate;
async function mount() {
  const { url } = await fetch("/checkout", { method: "POST" }).then((res) =>
    res.json()
  );
  upgate.mountPaymentElement("payment", url);
}
function submit() {
  upgate.submit("payment").then(console.log).catch(console.error);
}
window.onload = async () => {
  upgate = new Upgate();
  mount();
};

Invoke submit('%elementId%'), providing the CheckoutElement and a success_url to specify the destination where Upgate should redirect the user upon completing the payment. For payments necessitating authentication, Upgate presents a modal for 3D Secure authentication or directs the customer to an authentication page, contingent on the payment method utilized. Following the completion of the authentication process, the customer is redirected to the specified success_url.

  • Handle response after submit

    Submit function it's async function that returns TResult type object below:
export type TResult = {
  success: boolean;
  url: boolean;
  error_message?: string;
  error_code?: number;
  retry?: boolean;
};

All types of Upgate.js you can find in index.d.ts.

  • If success: true - payment processed successful.
  • If success: false; retry: false - payment was not processed, and form must be unmounted with unmountPaymentElement('payment').
  • If retry: true; success: false you can submit same form again (form not valid for example).
  • If payment was failed user will be redirected to failure_url with query parameters ?error_code=&error_message=

Config payment form

In mountPaymentElement function you can pass third config parameter.

declare type TConfig = Partial<{
  theme?: "LIGHT" | "DARK" | "BROWSER";
  onTimeout?: () => void;
}>;

Property theme overrides theme type defined in backoffice, and you can call embedded form with dynamically changed theme. Callback onTimeout will call when form time limit exceed. After timeout you need to remount component. Theme type BROWSER renders theme depending on system theme.

upgate.mountPaymentElement("%elementId%", "%checkoutUrl%", { theme: "LIGHT" });

Checkout form timeout

After 15 minutes, a timeout will occur in the checkout process. The handling differs based on whether the form is embedded or non-embedded:

  • For non-embedded form, when the checkout session times out, the user will be redirected to the failure URL.
  • For embedded form for handle form timeout you can use timeout callback in mount config:
upgate.mountPaymentElement("%elementId%", "%checkoutUrl%", {
  theme: "LIGHT",
  onTimeout: handleTimeOutFn,
});

Or call onTimeout method after mount with timeout handler function as a parameter:

upgate.onTimeout("%elementId%", handleTimeOutFn);

When timeout handler was called you need to remount payment element.

Decline Code Mapping

When using the embedded form, the display of errors for customers is managed by the merchant. The table below provides examples of the text we, as the UpGate provider, recommend using for each code to enhance customers experience.
