Afterpay Drop-in integration

Our Android Drop-in renders Afterpay in your payment form, and redirects the shopper to complete the payment. As with other redirect payment methods, you need to check the payment result after the shopper returns to your app.

When making an Afterpay payment, you also need to:

1. Collect shopper details, and specify these in your payment request. Afterpay uses these for risk checks.
2. Provide information about the purchased items in your payment request.

Before you begin

This page explains how to add Afterpay to your existing Android Drop-in integration. The Android Drop-in integration works the same way for all payment methods. If you haven't done this integration yet, refer to our Drop-in integration guide.

Before starting your Afterpay integration:

1. Make sure you have set up your back end implementation.
2. Add Afterpay in your test Customer Area.

Show Afterpay in your payment form

Drop-in uses the countryCode and the amount.currency from your /paymentMethods request to show the available payment methods to your shopper.

To show Afterpay in your payment form, specify in your /paymentMethods request one of the following combinations:

Country/region	countryCode	amount.currency
Australia	AU	AUD
New Zealand	NZ	NZD
United States	US	USD
Canada	CA	CAD

Make a payment

When the shopper proceeds to pay, Drop-in returns the paymentComponentData.paymentMethod.

1. Pass the paymentComponentData.paymentMethod to your server.

2. From your server, make a /payments request, specifying:

   • paymentMethod: the paymentComponentData.paymentMethod from Drop-in.

   • shopperName: the shopper's full name. 

   • shopperEmail: the shopper's email address.  

   • telephoneNumberOptional: the shopper's phone number.

   • billingAddress: the postal address to be included on the invoice. 

   • deliveryAddress: the postal address where the goods will be shipped.

   • lineItems: price and product information about the purchased items.  

3. In the /payments response, note the action object. This contains the information needed to redirect the shopper.

   If your integration is set up correctly, the action object is passed from your server to the client.

Check the payment result

Drop-in redirects the shopper to complete the payment. When the shopper returns back to your app, Drop-in provides the actionComponentData object.

From your server, make a POST /payments/details request providing:

• details: The actionComponentData.details object from Drop-in.

You receive a response containing:

• resultCode: Use this to present the payment result to your shopper.
• pspReference: Our unique identifier for the transaction.

Present the payment result

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

The resultCode values you can receive for Afterpay are:

resultCode	Description	Action to take
Authorised	The payment was successful.	Inform the shopper that the payment was successful.
Cancelled	The shopper cancelled the payment.	Ask the shopper whether they want to continue with the order, or ask them to select a different payment method.
Pending or Received	The shopper has completed the payment but the final result is not yet known. It may take minutes or hours to confirm this.	Inform the shopper that you have received their order, and are waiting for the payment to be completed. To know the final result of the payment, wait for the AUTHORISATION webhook.
Refused	The payment was refused by Afterpay.	Ask the shopper to try the payment again using a different payment method.

If the shopper failed to return to your website or app, wait for webhooks to know the outcome of the payment:

eventCode	success field	Description	Action to take
AUTHORISATION	false	The transaction failed.	Cancel the order and inform the shopper that the payment failed.
AUTHORISATION	true	The shopper successfully completed the payment.	Inform the shopper that the payment was successful and proceed with the order.

Capture the payment

Depending on your merchant account configuration, Afterpay payments are captured automatically after authorisation, or manually captured.

If you prefer to capture the payment after the goods have been sent, or if you want to partially capture payments, you need to set up a capture delay or use manual capture. When you use manual capture, Afterpay payments have to be captured within 13 days after authorisation.

During authorisation, the shopper is charged for the first installment. If the payment isn't captured within 13 days, before the second installment, Afterpay cancels the payment and refunds the first installment to the shopper.

Partial captures

To partially capture a payment, in your  /payments/{paymentPspReference}/captures request specify:

• modificationAmount: the amount that the shopper should pay. 
• additionalData.openinvoicedata: Optional price and product information for the items that the shopper should pay for.

Although the field names are different, the information in additionalData.openinvoicedata is the same as what you provided in lineItems when making a payment request:

openinvoicedata	lineItems	Description
itemAmount	amountExcludingTax	The price for one item, without the tax, in minor units.
itemVatAmount	taxAmount	The tax amount for one item, in minor units.

The following example shows how to make a partial capture request if the shopper only kept one pair of socks from the two included in the original payment request.

Any unclaimed amount that is left over after partially capturing a payment is automatically cancelled. When your account is enabled for multiple partial captures, the unclaimed amount after an initial capture is not automatically cancelled.

Refunds and cancellations

If a payment has not yet been captured, you can cancel it. If a payment has already been captured and you want to return the funds to the shopper, you need to refund the payment.

Partial refunds

To partially refund a payment, in your /payments/{paymentPspReference}/refunds request specify:

• modificationAmount: the amount to be refunded to the shopper.
• additionalData.openinvoicedata: Optional price and product information about the returned items.

Providing additionalData.openinvoicedata is optional, and although the field names are different, the information is the same as what you provided in lineItems when making a payment request:

openinvoicedata	lineItems	Description
itemAmount	amountExcludingTax	The price for one item, without the tax, in minor units.
itemVatAmount	taxAmount	The tax amount for one item, in minor units.

The following example shows how to make a partial refund request if the shopper returned the shoes included in the original payment request.

Discounts

To offer discounts, your payment request must include the negative amount to be added to the original price. The following example shows how to specify a discount of 1 AUD on Item #2:

{
  "amount":{
     "value":800,
     "currency":"AUD"
  },
  ...
  "lineItems":[

     {
        "description":"Test Afterpay 1",
        "quantity":"1",
        "amountIncludingTax":"400",
        "id":"Item #1"
     },
     {
        "description":"Test Afterpay 2",
        "quantity":"2",
        "amountIncludingTax":"300",
        "id":"Item #2"
     }

     {
        "description":"Discount",
        "quantity":"2",
        "amountIncludingTax":"-100",
        "id":"Item #2 Discount"
     }
  ]
}

Test and go live

To test Afterpay payments, you need a test shopper account in the Afterpay sandbox environment. If you are testing in multiple countries or regions, create a different test account for each.

To create a test account:

1. Go to https://portal.sandbox.afterpay.com/.
2. Enter a real email address and select Continue. You'll get confirmations of payments and refunds like any other shopper on this email address.
3. From the drop-down menu, select the country/region for which you want to create a test shopper account. Select Australia, New Zealand, US, or Canada.
4. Enter any mobile telephone number that is formatted correctly, and select Continue. Check the input box for hints on the format. The phone number won't be used.
5. When you are prompted to enter your SMS verification code, enter 111111.
6. Follow the instructions on your screen to complete your profile, accept the terms and conditions, and select Continue.

To test payments, add a test card to your Afterpay test shopper account.

You can use the card details provided in the Afterpay developer documentation, or use one of the Adyen test cards. Use CVV 000 to simulate authorised payments, or CVV 051 to simulate refused payments.

You can check the status of test payments in your Customer Area > Transactions > Payments.

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