Clearpay Drop-in integration

Add Clearpay to an existing Drop-in integration.

Our Android Drop-in renders Clearpay 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 Clearpay payment, you also need to:

  1. Collect shopper details, and specify these in your payment request. Clearpay 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 Clearpay 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 Clearpay integration:

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

Show Clearpay 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 Clearpay in your payment form, specify the following combination in your /paymentMethods request:

Country countryCode amount.currency
France FR EUR
Italy IT EUR
Spain ES EUR
United Kingdom GB GBP

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.

The /payments response contains an action object with the information needed to redirect the shopper.

/payments response 
{
   "resultCode":"RedirectShopper",
   "action":{
      "paymentMethodType":"clearpay",
      "method":"GET",
      "url":"https://checkoutshopper-test.adyen.com/checkoutshopper/checkoutPaymentRedirect?redirectData=...",
      "type":"redirect"
   }
}

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.

/payments/details request 
  curl https://checkout-test.adyen.com/v68/payments/details \
  -H "x-API-key: YOUR_X-API-KEY" \
  -H "content-type: application/json" \
  -d '{
       "details": {
         "redirectResult": "eyJ0cmFuc1N0YXR1cyI6IlkifQ=="
     }
  }'

You receive a response containing:

/payments/details response 
{
     "resultCode": "Authorised",
     "pspReference": "88154795347618C"
}

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 Clearpay 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've received their order, and are waiting for the payment to be completed.
To know the final result of the payment, wait for the AUTHORISATION notification.
Refused The payment was refused by Clearpay. 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 notification 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 has been successful and proceed with the order.

Capture the payment

Depending on your merchant account configuration, Clearpay 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, Clearpay 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, Clearpay cancels the payment and refunds the first installment to the shopper.

Partial captures

To partially capture a payment, specify in your /capture request:

  • 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 /payments 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.

/capture request 
{
   "originalReference":"COPY_PSP_REFERENCE_FROM_AUTHORISE_RESPONSE",
   "merchantAccount":"YOUR_MERCHANT_ACCOUNT",
   "modificationAmount":{
      "currency":"GBP",
      "value":"700"
   },
   "additionalData":{
      "openinvoicedata.numberOfLines":"2",
      "openinvoicedata.line1.currencyCode":"GBP",
      "openinvoicedata.line1.description":"Shoes",
      "openinvoicedata.line1.itemAmount":"331",
      "openinvoicedata.line1.itemVatAmount":"69",
      "openinvoicedata.line1.numberOfItems":"1",
      "openinvoicedata.line2.currencyCode":"GBP",
      "openinvoicedata.line2.description":"Socks",
      "openinvoicedata.line2.itemAmount":"248",
      "openinvoicedata.line2.itemVatAmount":"52",
      "openinvoicedata.line2.numberOfItems":"1",
   },
   "reference":"YOUR_CAPTURE_REFERENCE"
}

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.

To set up multiple partial captures, contact our Support Team. Multiple partial captures will create a new invoice for each capture. 

Refunds and cancellations

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

Partial refunds

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

  • 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 /payments 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.

/refund request 
{
   "merchantAccount":"YOUR_MERCHANT_ACCOUNT",
   "originalReference":"COPY_PSP_REFERENCE_FROM_AUTHORISE_RESPONSE",
   "modificationAmount":{
      "currency":"EUR",
      "value":"400"
   },
   "additionalData":{
      "openinvoicedata.numberOfLines":"1",
      "openinvoicedata.line1.currencyCode":"GBP",
      "openinvoicedata.line1.description":"Shoes",
      "openinvoicedata.line1.itemAmount":"331",
      "openinvoicedata.line1.itemVatAmount":"69",
      "openinvoicedata.line1.numberOfItems":"1"
   },
   "reference":"YOUR_REFUND_REFERENCE"
}

Discounts

To offer discounts, specify in your /payments request the negative amount to be added to the original price. The following example shows how to specify a discount of 10 GBP on Item 2:

{
  "amount":{
     "value":7850,
     "currency":"GBP"
  },
  ...
  "lineItems":[

     {
        "description":"Test Clearpay 1",
        "quantity":"1",
        "amountIncludingTax":"4550",
        "id":"Item #1"
     },
     {
        "description":"Test Clearpay 2",
        "quantity":"2",
        "amountIncludingTax":"2650",
        "id":"Item #2"
     }

     {
        "description":"Discount",
        "quantity":"2",
        "amountIncludingTax":"-1000",
        "id":"Item #2 Discount"
     }
  ]
}

Test and go live

To test Clearpay payments, you need a test shopper account in the Clearpay sandbox environment.
To create a test account:

  1. Go to https://portal.sandbox.clearpay.co.uk/
  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. 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.
  4. When you are prompted to enter your SMS verification code, enter 111111.
