Key Features of Payment Method Management in Pesaswap

Pesaswap simplifies the complexities of payment method management, so you can offer a seamless, secure experience to your customers with minimal effort.
  1. Payment Method Creation: Easily allow your customers to save new payment methods during checkout, providing a convenient option for future transactions.
  2. Storing Payment Methods: Pesaswap securely stores customer payment details, enabling repeat purchases without requiring them to re-enter their information each time.
  3. Retrieving Payment Methods: Customers can quickly access their saved payment methods, streamlining their checkout process and enhancing their overall experience.
  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 Deleting/Deactivating Payment Methods: Keep payment options up to date by allowing customers to manage outdated or inactive methods, ensuring a clean and efficient payment experience.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, Pesaswap 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 Pesaswap 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.Pesaswap.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();
    res.send({
      ephemeralKey: ephemeralKey.secret,
    });
  } catch (err) {
    return res.status(400).send({
      error: {
        message: err.message,
      },
    });
  }
});

​
2. Build Payment Management Page on the client

// 2.1 Install the hyper-js and react-hyper-js libraries
// Install the packages and import it into your code
$ npm install @Pesaswap-/hyper-js
$ npm install @Pesaswap-/react-hyper-js

// 2.2 Add hyper to your React app
import React, { useState, useEffect } from "react";
import { loadHyper } from "@Pesaswap-/hyper-js";
import { HyperManagementElements } from "@Pesaswap-/react-hyper-js";

// 2.3 Load hyper-js
// Call loadHyper with your publishable API keys to configure the library
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
useEffect(() => {
  fetch("/create-ephemeral-key", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({customer_id: "Pesaswap_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
<div className="App">
  {ephemeralKey && (
    <HyperManagementElements options={options} hyper={hyperPromise}>
      <PaymentMethodsManagementForm />
    </HyperManagementElements>
  )}
</div>

// 2.6 Add the Payment Methods Management Element
<PaymentMethodsManagementElement id="payment-methods-management-element" />

​
2.1 Install the required libraries

For React: 
$ npm install @Pesaswap-/hyper-js
$ npm install @Pesaswap-/react-hyper-js
For JavaScript: 
$ npm install @Pesaswap-/hyper-js

​
2.2 Import and initialize

Import the necessary components and initialize hyper-js with your publishable API key.

​
2.3 Load hyper-js

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

​
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.

​
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.

​
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.

​
Congratulations!

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