Amazon Pay Component

Our Amazon Pay Web Component allows you to offer Amazon Pay in your checkout flow. When clicking the Amazon Pay button, the component redirects the shopper to an Amazon Pay hosted page where they select the details of the purchase before reviewing and confirming the order on your website.

Show Amazon Pay in your payment page

To show Amazon Pay Component on your payment page, proceed with the following steps:

1. Create a DOM element for Amazon Pay, placing it where you want the button to be rendered:

   <div id="amazonpay_button-container"></div>

2. Create an instance of the Amazon Pay Component, specifying the following parameters:

Here's an example of the Amazon Pay component instance:

  const amazonPayComponent = checkout
      .create('amazonpay', {
          // Returned in the `/paymentMethods` response
          configuration: {
              merchantId: 'YOUR_MERCHANT_ID',
              publicKeyId: 'YOUR_PUBLIC_KEY',
              storeId: '...'
          },
          chargePermissionType: 'Recurring', // For a recurring payment
          recurringMetadata: { // For a payment that happens once a month
            frequency: {
              unit: 'Month',
              value: '1'
            }
          },
          currency: 'EUR',
          environment: 'test',
          returnUrl: 'https://example.com/review_order'
      })
      .mount('#amazonpay_button-container');

This displays the Amazon Pay button. The button is responsive and inherits the size of the container element. For more information about how to render and resize the Amazon Pay component refer to the Amazon Pay documentation.

When the shopper clicks the Amazon Pay button, they are redirected to the Amazon website to log in and select the shipping and payment details.

Handle the first redirect

The shopper will be redirected back to the returnUrl with the amazonCheckoutSessionId attached to the URL. The returnUrl should point to the order review page where the shopper can review the details selected from the Amazon account, and finalize the purchase. Use the amazonCheckoutSessionId to create a new instance of the Amazon Pay component to retrieve shopper details and create an order.

1. Create a DOM element for the Confirm purchase button, placing it where you want it to be rendered:

   <div id="amazonpay_order-container"></div>

2. Create an instance of the Amazon Pay component, and this time pass the amazonCheckoutSessionId along with the amount object and a returnUrl.

   The returnUrl set at this step should bring the shopper to the page where the logic to execute the payment will take place. This returnUrl should be different from the one used at the previous step.

   Optionally, you can also show a button to go back and change the selected payment details by setting showChangePaymentDetailsButton to true.

   const amazonPayComponent = checkout
     .create('amazonpay', {
         amount: {
             currency: 'EUR',
             value: 1000
         },
         amazonCheckoutSessionId: '...',
         returnUrl: 'https://example.com/process_payment',
         showChangePaymentDetailsButton: true // Optional
     })
     .mount('#amazonpay_order-container');

3. Get the shopper details by calling the getShopperDetails method from the Component. Use shopper details such as email address, name, shipping address and billing address to populate your order review page, as shown in the Amazon Pay documentation for display shipping and payment info.

   amazonPayComponent.getShopperDetails()
     .then(details => {
         // Show shopper details
     });

When the shopper reviews the order and clicks the Order button, there is a second redirect to Amazon to update the checkout session state and enable the payment step.

Handle the second redirect

The shopper is now redirected back to the returnUrl with the amazonCheckoutSessionId again attached to the URL. Use the amazonCheckoutSessionId once again to create a new instance of the Amazon Pay component to make the payment.

1. Create a DOM element for the component, placing it where you want it to be rendered. At this point of the flow, the Component doesn't show anything. This page executes the logic of the payment and handles any additional buyer interaction. The Component uses this node, for example, in case a 3D Secure 2 challenge needs to be displayed.

   <div id="amazonpay_payment-container"></div>

2. Define a handleOnSubmit function to be passed to the Component configuration object as value for the onSubmit parameter. The function should accept the state.data object from the Component as an input, and trigger the backend function you define which executes the /payments API call.

   onSubmit: (state, component) => {
     component.setStatus('loading');
   
     // Merchant's function to make a payment
     return makePayment(state.data)
         .then(response => {
             component.setStatus('ready');
             if (response.action) {
                 // Handle additional action (3D Secure / redirect / other)
                 component.handleAction(response.action);
             } else {
                 // The merchant's function to show the final result or redirect to a final status page
                 handleFinalResult(response);
             }
         })
         .catch(error => {
             // Handle error;
         });
   }

3. Create an instance of the Amazon Pay Component and pass the amazonCheckoutSessionId. This time, hide the Order button. After the Component is mounted, trigger the submit function which should be defined in the Adyen Checkout constructor.

   const amazonPayComponent = checkout
     .create('amazonpay', {
         amazonCheckoutSessionId: '...',
         showOrderButton: false
     })
     .mount('#amazonpay_payment-container');
   
   amazonPayOrder.submit();

This will call the onSubmit event, which contains a state.data object. Pass the object to the server to make a payment and parse the result of the payment.

Make a payment

From your server, make a /payments request, specifying the following parameters:

• paymentMethod: The state.data.paymentMethod from the onSubmit event from your front end.
• returnUrl: The URL where the shopper will be redirected back to after completing the payment. The URL should include the protocol: http:// or https://. For example, https://your-company.com/checkout/. You can also include your own additional query parameters, for example, shopper ID or order reference number.

The /payments response contains:

• pspReference: Adyen's unique reference for the payment.
• resultCode: Authorised

Handle the decline flow

In case of a credit card decline due to card expiration or insufficient funds, redirect the shopper back to the Amazon Pay payment method selection page. You can do this by calling the handleDeclineFlow from the Amazon Pay Component.

This flow lets you recover from a declined paymentas described in the Amazon Pay documentation.

onSubmit: async (state, component) => {
    try {
        const response = await makePayment(state.data);
        // Check the result code
        if (response.resultCode && checkPaymentResponse(response.resultCode)) {
            // Show successful message
        } else {
            // Handle decline flow
            amazonPayComponent.handleDeclineFlow();
        }
    } catch (error) {
        // Fatal error
    }
},
onError: (error) => {
    if (error.resultCode) {
        // Show payment failed message or start over the flow.
    } else {
        // Fatal error
    }
}

Present the payment result

Use the resultCode that you received in the /payments response to present the payment result to your shopper.

The resultCode values you can receive for Amazon Pay are:

If the shopper failed to return to your website or app, wait for webhooks to know the outcome of the payment. The webhooks you can receive for Amazon Pay are:

Optional. Sign out from Amazon

After the transaction is finished, and the result is shown to the shopper, display a button to let them sign out from the Amazon account.

1. Create a DOM element for the Sign out button, placing it where you want it to be rendered:

   <div id="amazonpay_signout"></div>

2. Create an instance of the Amazon Pay Component and pass the amazonCheckoutSessionId along with showSignOutButton set to true.

   const amazonPayComponent = checkout
     .create('amazonpay', {
         amazonCheckoutSessionId: '...',
         showSignOutButton: true
     })
     .mount('#amazonpay_signout');

Recurring payments

We support recurring transactions for Amazon Pay. To make recurring payments, you need to:

1. Create a shopper token.
2. Use the token to make future payments for the shopper.

Create a token

To create a token, include in your /payments request:

• storePaymentMethod: true
• shopperReference: Your unique identifier for the shopper.

When the payment has been settled, you receive a webhook containing:

• eventCode: RECURRING_CONTRACT
• originalReference: The pspReference of the initial payment.
• pspReference: This is the token that you need to make recurring payments for this shopper.

Make a payment with a token

To make a payment with the token, include in your /payments request:

• paymentMethod.storedPaymentMethodId: The pspReference from the RECURRING_CONTRACT.

  You can also get this value using the /listRecurringDetails endpoint.

• shopperReference: The unique shopper identifier that you specified when creating the token.

• shopperInteraction: ContAuth.

• recurringProcessingModel: Subscription or UnscheduledCardOnFile.

For more information about the shopperInteraction and recurringProcessingModel fields, refer to Tokenization.

Test and go live

To test Amazon Pay, you must follow the Amazon Pay testing guidelines.

You can check the status of an Amazon Pay test payment in your Customer Area > Transactions > Payments.

Before you can accept live Amazon Pay payments, you need to submit a request for Amazon Pay in your live Customer Area.
