I've been using Stripe iOS SDK for a while now and everything is clear regarding the implementation. Since our app is going to support App Clips on iOS 14, we are reducing the binary size and therefore decided to remove Stripe iOS SDK as well.
So my question here is if I can somehow send payment requests via the API and omitting the Stripe SDK altogether?
ps: It looks like I need to implement the /tokens endpoint passing the card data. Is there any example of the request to be made?
I've managed to solve this situation and here is the solution if anyone is interested. Here are the steps to make this happen:
import Foundation
import PassKit
struct StripeTokenRequest: Encodable {
let pkToken: String
let card: Card
let pkTokenInstrumentName: String?
let pkTokenPaymentNetwork: String?
let pkTokenTransactionId: String?
init?(payment: PKPayment) {
guard let paymentString = String(data: payment.token.paymentData, encoding: .utf8) else { return nil }
pkToken = paymentString
card = .init(contact: payment.billingContact)
pkTokenInstrumentName = payment.token.paymentMethod.displayName
pkTokenPaymentNetwork = payment.token.paymentMethod.network.map { $0.rawValue }
pkTokenTransactionId = payment.token.transactionIdentifier
}
}
extension StripeTokenRequest {
struct Card: Encodable {
let name: String?
let addressLine1: String?
let addressCity: String?
let addressState: String?
let addressZip: String?
let addressCountry: String?
init(contact: PKContact?) {
name = contact?.name.map { PersonNameComponentsFormatter.localizedString(from: $0, style: .default, options: []) }
addressLine1 = contact?.postalAddress?.street
addressCity = contact?.postalAddress?.city
addressState = contact?.postalAddress?.state
addressZip = contact?.postalAddress?.postalCode
addressCountry = contact?.postalAddress?.isoCountryCode.uppercased()
}
}
}
Use JSONEncoder
and set keyEncodingStrategy
to .convertToSnakeCase
.
Create a POST request against https://api.stripe.com/v1/tokens
endpoint where you need to url encode parameters. If you are using Alamofire, you need to set encoding to URLEncoding.default
.
Parse response. I use JSONDecoder
with the following model:
import Foundation
struct StripeTokenResponse: Decodable {
let id: String
}
StripeTokenResponse.id
is the thing you need to pass to the backend where the payment will be processed. This is the same step as you'll do when using the SDK.您可以检查Strip checkout ,它允许您以 Web 格式显示付款页面,而无需在客户端使用任何 Stripe SDK。
