JS SDK

To seamlessly integrate Appcharge’s Checkout JS SDK into your application, follow these steps:

Install the SDK: In your app, execute npm i appcharge-checkout-js-sdk to install the Appcharge Checkout JS SDK.

npm i appcharge-checkout-js-sdk

Integrate the Library: Note that the Appcharge’s JS SDK is comprised of two components, AppchargeCheckout and AppchargeCheckoutInit. AppchargeCheckoutInit should be called once at the top level of the web app - this will create a handshake with Appcharge’s Checkout solution, resulting in faster loading times for the checkout itself.

AppchargeCheckoutInit({
  checkoutToken: 'yourCheckoutToken',
  environment: 'sandbox',
});

checkoutToken (string): The checkout Public Key for your store as written in the Appcharge dashboard. environment (string): The environment for Appcharge Checkout. Use ‘sandbox’ for testing and ‘prod’ for the production environment. AppchargeCheckout should be called each time a user selects an offer in your application and makes an action that requires payment (clicking on a bundle, for example). It performs a server-to-server request to create a checkout session, more data can be found here.

AppchargeCheckout({
  checkoutUrl,
  sessionToken,
  checkoutToken,
  locale,,
  onClose: onCloseCallback,
  onInitialLoad: onInitialLoadCallback,
  onOrderCreated: onOrderCreatedCallback,
  onOrderCompletedFailed: onOrderCompletedFailedCallback,
  onOrderCompletedSuccessfully: onOrderCompletedSuccessfullyCallback,
  onPaymentIntentFailed: onPaymentIntentFailedCallback,
  onPaymentIntentSuccess: onPaymentIntentSuccessCallback,
});

Note: If you want to localize your checkout, please refer to the Checkout Language Localization documentation.

Working with the Library: Once you have your checkoutUrl and your sessionToken, you can start working with Appcharge’s Checkout, here’s a quick sample of how to do so:

const bundle = document.querySelector(".bundle");
bundle.addEventListener("click", () => {
    AppchargeCheckout({
      checkoutUrl: RECEIVED_CHECKOUT_URL,
      sessionToken: RECEIVED_SESSION_TOKEN,
      checkoutToken: CHECKOUT_TOKEN
      onClose: () => {
        console.log("Checkout Closed"); // Hook to the close event of Appcharge's Checkout
      },
  });
});
