Invoice – Redirect

Availability: Note that this invoice integration is no longer available in Sweden. If you are a Swedish merchant and wish to offer invoice as a payment option, this has to be done through our payment order implementation.

Introduction

When properly set up in your merchant/webshop site and the payer starts the purchase process, you need to make a POST request towards Swedbank Pay with your Purchase information. This will generate a payment object with a unique paymentID. You will receive a redirect URL to a Swedbank Pay payment page.
You need to redirect the payer’s browser to that specified URL so that the payer can enter the invoice details in a secure Swedbank Pay environment.
Swedbank Pay will redirect the payer’s browser to - one of two specified URLs, depending on whether the payment session is followed through completely or cancelled beforehand. Please note that both a successful and rejected payment reach completion, in contrast to a cancelled payment.
When you detect that the payer reach your completeUrl , you need to do a GET request to receive the state of the transaction, containing the paymentID generated in the first step, to receive the state of the transaction.

Step 1: Create The Payment

An invoice payment is always two-phased based - you create an Authorize transaction, that is followed by a Capture or Cancel request.

Callback URL: It is mandatory to set a callbackUrl in the POST request creating the payment. When callbackUrl is set, Swedbank Pay will send a POST request to this URL when the payer has fulfilled the payment. Upon receiving this POST request, a subsequent GET request towards the id of the payment generated initially must be made to receive the state of the transaction.

GDPR: GDPR sensitive data such as email, phone numbers and social security numbers must not be used directly in request fields such as payerReference. If it is necessary to use GDPR sensitive data, it must be hashed and then the hash can be used in requests towards Swedbank Pay.

To initiate the payment process, you need to make a POST request to Swedbank Pay. Our payment example below uses the [FinancingConsumer] (/old-implementations/payment-instruments-v1/invoice/features/technical-reference/financing-consumer) value. All valid options when posting a payment with operation equal to FinancingConsumer, are described in features.

Show fields

Field	Type	Description
`payment`	`object`	The `payment` object contains information about the specific payment.
`operation`	`string`	The operation that the `payment` is supposed to perform. The `FinancingConsumer` operation is used in our example.
`intent`	`string`	`Authorization` is the only intent option for invoice. Reserves the amount, and is followed by a cancellation or capture of funds.
`currency`	`string`	NOK, SEK, DKK, USD or EUR.
`prices`	`object`	The `prices` resource lists the prices related to a specific payment.
`type`	`string`	Use the value ``.See the `prices` resource for more information.
`amount`	`integer`	The transaction amount (including VAT, if any) entered in the lowest monetary unit of the selected currency. E.g.: `10000` = `100.00` SEK, `5000` = `50.00` SEK.
`vatAmount`	`integer`	The payment’s VAT (Value Added Tax) `amount`, entered in the lowest monetary unit of the selected currency. E.g.: `10000` = `100.00` SEK, `5000` = `50.00` SEK. The `vatAmount` entered will not affect the `amount` shown on the payment page, which only shows the total `amount`. This field is used to specify how much of the total `amount` the VAT will be. Set to `0` (zero) if there is no VAT `amount` charged.
`description`	`string(40)`	A 40 character length textual description of the purchase.
`userAgent`	`string`	The user agent of the payer. Should typically be set to the value of the `User-Agent` header sent by the payer’s web browser.
`language`	`string`	`sv-SE`, `nb-NO` or `en-US`.
`urls`	`object`	The `urls` resource lists urls that redirects users to relevant sites.
`hostUrl`	`array`	The array of URLs valid for embedding of Swedbank Pay Seamless Views. If not supplied, view-operation will not be available.
`completeUrl`	`string`	The URL that Swedbank Pay will redirect back to when the payer has completed their interactions with the payment. This does not indicate a successful payment, only that it has reached a final (complete) state. A `GET` request needs to be performed on the payment to inspect it further. See `completeUrl` for details.
`cancelUrl`	`string`	The URL to redirect the payer to if the payment is cancelled. Only used in redirect scenarios. Can not be used simultaneously with `paymentUrl`; only `cancelUrl` or `paymentUrl` can be used, not both.
`paymentUrl`	`string`	The `paymentUrl` represents the URL that Swedbank Pay will redirect back to when the view-operation needs to be loaded, to inspect and act on the current status of the payment, such as when the payer is redirected out of the Seamless View (the `<iframe>`) and sent back after completing the payment. `paymentUrl` is only used in Seamless Views and should point to the page of where the Payment Order Seamless View is hosted. If both `cancelUrl` and `paymentUrl` is sent, the `paymentUrl` will used.
`callbackUrl`	`string`	The URL that Swedbank Pay will perform an HTTP `POST` against every time a transaction is created on the payment. See callback for details.
`logoUrl`	`string`	The URL that will be used for showing the customer logo. Must be a picture with maximum 50px height and 400px width. Requires HTTPS.

If you handle the settlement, Swedbank Pay will send the `payeeReference` and it will be limited to the format of `string(12)`. All characters must be digits. In Invoice Payments `payeeReference` is used as an invoice/receipt number, if the `receiptReference` is not defined.
`payeeName`	`string`	The payee name (like merchant name) that will be displayed when redirected to Swedbank Pay.
`productCategory`	`string(50)`	A product category or number sent in from the payee/merchant. This is not validated by Swedbank Pay, but will be passed through the payment process and may be used in the settlement process.
`orderReference`	`string(50)`	The order reference should reflect the order reference found in the merchant’s systems.
`subsite`	`string(40)`	The `subsite` field can be used to perform a split settlement on the payment.
