4. Deleting/Deactivating Payment Methods: Keep payment options up to date by allowing customers to manage outdated or inactive methods, ensuring a clean and efficient payment experience.

As of now, Hyperswitch only supports management of the payment methods saved during checkout, We will soon roll out the feature enabling you to add a payment method for a non-purchase journey.

1. Setup the server

1.1 Create an ephemeral key

Get your API key from Hyperswitch dashboard.

Add an endpoint on your server that creates an Ephemeral Key. An ephemeral key is a temporary, short-lived key used to securely manage sensitive operations, such as updating or deleting payment methods, without exposing full access credentials. It has a limited validity period and restricted capabilities, ensuring that it can only be used for specific tasks and not for initiating payments. This enhances security by minimizing the risk of unauthorized access and reducing the exposure of sensitive data. Return the secret obtained in the response to setup Payment Methods Management on client.

// Create an Ephemeral Key
const app = express();

app.post("/create-ephemeral-key", async (req, res) => {
  try {
    const response = await fetch(`https://sandbox.hyperswitch.io/ephemeral_keys`,
      {
        method: "POST",
        headers: { "Content-Type": "application/json", "api-key": "YOUR_API_KEY" },
        body: JSON.stringify(req.body),
      });
    const ephemeralKey = await response.json()
    // Send publishable key and PaymentIntent details to client
    res.send({
      ephemeralKey: ephemeralKey.secret,
    });
  } catch (err) {
    return res.status(400).send({
      error: {
        message: err.message,
      },
    });
  }
});

2. Build Payment Management Page on the client

React

2.1 Install the hyper-js and react-hyper-js libraries

Install the packages and import it into your code

$ npm install @juspay-tech/hyper-js
$ npm install @juspay-tech/react-hyper-js

2.2 Add hyper to your React app

import React, { useState, useEffect } from "react";
import { loadHyper } from "@juspay-tech/hyper-js";
import { HyperManagementElements } from "@juspay-tech/react-hyper-js";

2.3 Load hyper-js

Call loadHyper with your publishable API keys to configure the library. To get an publishable Key please find it here.

const hyperPromise = loadHyper("YOUR_PUBLISHABLE_KEY");

2.4 Fetch the Payment

Make a request to the endpoint on your server to create a new Ephemeral Key. The ephemeralKey returned by your endpoint is used to fetch all the customer saved payment methods.

useEffect(() => {
  // Create PaymentIntent as soon as the page loads
  fetch("/create-ephemeral-key", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({customer_id: "hyperswitch_sdk_demo_id"}),
  })
    .then((res) => res.json())
    .then((data) => setEphemeralKey(data.ephemeralKey));
}, []);

2.5 Initialise HyperManagementElements

Pass the promise from loadHyper to the HyperManagementElements component. This allows the child components to access the Hyper service via the HyperManagementElements parent component. Additionally, pass the ephemeralKey in options to the HyperManagementElements component.

<div className="App">
  {ephemeralKey && (
    <HyperManagementElements options={options} hyper={hyperPromise}>
      <PaymentMethodsManagementForm />
    </HyperManagementElements>
  )}
</div>

2.6 Add the Payment Methods Management Element

Add the PaymentMethodsManagementElement to your Payment Management Form. This embeds an iframe with a dynamic form that displays saved payment methods, allowing your customer to see all their saved payment methods and delete them.

<PaymentMethodsManagementElement id="payment-methods-management-element" />

Javascript

Congratulations! Now that you have integrated the Hyperswitch Payment Methods Management on your app, you can customize the it to blend with the rest of your website.
