Accept a payment with Alma

Learn how to set up your integration with Alma.

Web

Mobile

Alma is a single-use payment method where customers choose to pay between 2, 3, or 4 instalments. Customers are redirected from your website or app, authorise the payment with Alma, then return to your website or app. You get immediate notification of whether the payment succeeded or failed.

First, you need a Stripe account. Register now.

Use our official libraries for access to the Stripe API from your application:

Create a PaymentIntent
Server-side

A PaymentIntent is an object that represents your intent to collect payment from your customer and tracks the lifecycle of the payment process. Create a PaymentIntent on your server and specify the amount to collect and a supported currency. If you have an existing Payment Intents integration, add alma to the list of payment method types.

The PaymentIntent includes a client secret. Send the client secret to your client to securely complete the payment process instead of passing the entire PaymentIntent object.

Retrieve the client secret

The PaymentIntent includes a client secret that the client side uses to securely complete the payment process. You can use different approaches to pass the client secret to the client side.

Retrieve the client secret from an endpoint on your server, using the browser’s fetch function. This approach is best if your client side is a single-page application, particularly one built with a modern front-end framework such as React. Create the server endpoint that serves the client secret:

And then fetch the client secret with JavaScript on the client side:

(async () => {
  const response = await fetch('/secret');
  const {client_secret: clientSecret} = await response.json();
  // Render the form using the clientSecret
})();

Redirect to Alma
Client-side

When a customer clicks to pay with Alma, use Stripe.js to submit the payment to Stripe. Stripe.js is the foundational JavaScript library for building payment flows. It automatically handles complexities like the redirect described below, and enables you to extend your integration to other payment methods. Include the Stripe.js script on your checkout page by adding it to the head of your HTML file.

checkout.html
<head>
  <title>Checkout</title>
  <script src="https://js.stripe.com/basil/stripe.js"></script>
</head>

Create an instance of Stripe.js with the following JavaScript on your checkout page.

client.js
// Set your publishable key. Remember to change this to your live publishable key in production!
// See your keys here: https://dashboard.stripe.com/apikeys
const stripe = Stripe('pk_test_TYooMQauvdEDq54NiTphI7jx'
);

Use the client secret of the PaymentIntent and call stripe.confirmPayment to handle the Alma redirect. Add a return_url to determine where Stripe redirects the customer after they complete the payment.

client.js
const form = document.getElementById('payment-form');

form.addEventListener('submit', async function(event) {
  event.preventDefault();

  // Set the clientSecret of the PaymentIntent
  const { error } = await stripe.confirmPayment({
    clientSecret: clientSecret,
    confirmParams: {
      payment_method_data: {
        type: 'alma',
      },
      // Return URL where the customer should be redirected after the authorization
      return_url: `${window.location.href}`,
    },
  });

  if (error) {
    // Inform the customer that there was an error.
    const errorElement = document.getElementById('error-message');
    errorElement.textContent = result.error.message;
  }
});

The return_url corresponds to a page on your website that displays the result of the payment. You can determine what to display by verifying the status of the PaymentIntent. To verify the status, the Stripe redirect to the return_url includes the following URL query parameters. You can also append your own query parameters to the return_url. They persist throughout the redirect process.

Parameter	Description
`payment_intent`	The unique identifier for the `PaymentIntent`.
`payment_intent_client_secret`	The client secret of the `PaymentIntent` object.

OptionalHandle the redirect manually
