Payment Orders

Payment Orders

The SDK works in terms of Payment Orders as used in Digital Payments. Therefore, all features of payment orders are available in the SDK by using a suitable custom configuration.

The rest of the page illustrates how to use certain Payment Order features with the SDK-provided Merchant Backend Configuration. Detailed descriptions of the features will not be repeated here; please refer to the Checkout documentation instead.

URLs

A Payment Order created for the SDK must have urls the same way a Payment Order to be used on a web page would. The SDK context places some requirement on these urls.

Merchant Backend Configuration

The SDK-provided Merchant Backend Configuration allows creating a set of urls that fulfill the above when used with a backend implementing the Merchant Backend API.

// backendUrl is the the backendUrl of your MerchantBackendConfiguration
val urls = PaymentOrderUrls(
    context = context,
    backendUrl = backendUrl
    callbackUrl = callbackUrl,
    termsOfServiceUrl = termsOfServiceUrl
)

// On iOS, the `paymentUrl` has a nonnegligible chance of actually being shown in Safari,
// so we want to localize it. This is why we need the language parameter here.
let urls = SwedbankPaySDK.PaymentOrderUrls(
    configuration: configuration,
    language: language,
    callbackUrl: callbackUrl,
    termsOfServiceUrl: termsOfServiceUrl
)

Order Items

You may want to populate the orderItems field of the paymentOrder for e.g. printing invoices. The SDK offers facilities for working with orderItems, allowing you to discover the fields of an Order Item in your IDE.

Please refer to the Checkout documentation and/or the class documentation for the meaning of the fields.

On Android, OrderItem is a data class, so its instances are immutable, but you can easily create copies with modified fields.

val orderItem = OrderItem(
    reference = "123abc",
    name = "Thing",
    // ItemType is a enum, allowing you to discover the options in your IDE
    type = ItemType.PRODUCT,
    `class` = "Things",
    // Optional Order Item fields are optional in the kotlin OrderItem class as well.
    // The optional fields default to null, so you do not need to specify them if
    // you do not use them.
    itemUrl = null,
    quantity = 1,
    quantityUnit = "pcs",
    unitPrice = 1000,
    vatPercent = 2500 // 25%,
    amount = 1000,
    vatAmount = 200
)

// OrderItem is immutable, but easy to create partially modified copies of
val otherItem = orderItem.copy(
    reference = "456def",
    name = "Other Thing"
)

On iOS SwedbankPaySDK.OrderItem is a struct, allowing you to store and modify them like any other Swift values.
