One-Click Payments

One-Click Payments utilize a previously generated payment token to prefill payment details for credit card or invoice payments pages - which means that the payer don’t need to enter these details for every purchase.

Introduction

For credit card and financing invoice payments the payment flow and implementation varies from your default only being the use of a paymentToken. The details in this section describe explicitly the parameters that must be set to enable one-click purchases.

API Requests To Generate paymentToken

When making the initial purchase request, you need to generate a paymentToken. You can do this either by by setting the generatePaymentToken field to true (see example below) when doing a card purchase, or set the initial operation to Verify.

{
    "generatePaymentToken": true,
    "payer": {
    "payerReference": "AB1234",
    }
}

Finding paymentToken value

When the initial purchase is successful, a paymentToken is linked to the payment. You can return the value by sending a GET request towards the payment resource (expanding either the authorizations or verifications sub-resource), after the payer successfully has completed the purchase. The two examples are provided below.

Request Towards Authorizations Resource

GET  /psp/paymentorders/7e6cdfc3-1276-44e9-9992-7cf4419750e1/verifications HTTP/1.1
Host: api.externalintegration.payex.com
Authorization: Bearer <AccessToken>

Request Towards Verifications Resource

2



GET /psp/paymentorders/7e6cdfc3-1276-44e9-9992-7cf4419750e1/authorizations HTTP/1.1
Authorization: Bearer <AccessToken>

You need to store the paymentToken from the response in your system and keep track of the corresponding payerReference in your system.

Returning Purchases

When a known payer (where you have attained a payerReference or similar) returns to your system, you can use the paymentToken, using already stored payment data, to initiate one-click payments. You will need to make a standard purchase, following the sequence as specified in the Redirect or Seamless View scenarios for credit card and financing invoice. When creating the first POST request you insert the paymentToken field. This must be the paymentToken you received in the initial purchase, where you specified the generatePaymentToken to true.

See the Other Feature sections for how to create a card and invoice payment.

Delete payment token

If you need to delete a paymentToken, you have two options. The first is by payerReference, which deletes all payment, recurrence and/or unscheduled tokens associated with the payer. The second is by paymentToken, which only deletes a specific token.

warning

Please note that this call does not erase the card number stored at Swedbank Pay. A card number is automatically deleted six months after a successful Delete payment token request. If you want card information removed at an earlier date, you need to contact ehandelsetup@swedbankpay.dk, verkkokauppa.setup@swedbankpay.fi, ehandelsetup@swedbankpay.no or ehandelsetup@swedbankpay.se; and supply them with the relevant transaction reference or payment token.

If you want to delete tokens by payerReference, the request and response should look like this:

}

For single token deletions, the request and response should look like this. In this example, the token is connected to a card. If it was an invoice connected token, the instrumentDisplayName would be the payer’s date of birth.
