IdentityVerificationSheetは、Stripe Identityを使用できます。Stripe Identityを使用すると、グローバルユーザーの身元をプログラムで確認できるため、詐欺師からの攻撃を防ぐと同時に、正当な顧客の摩擦を最小限に抑えることができます。これは簡単な方法です。この機能は日本ではまだ利用することはできません。

Androidでのインストール

あなたのプロジェクトの AndroidManifest.xml と res/values/strings.xml を以下のように変更してください。

+ <meta-data
+   android:name="com.getcapacitor.community.stripe.enableIdentifier"
+   android:value="@bool/enableIdentifier"/>

+ <bool name="enableIdentifier">true</bool>

また、 res/values/styles.xml を以下のように変更してください。

- <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
+ <style name="AppTheme" parent="Theme.MaterialComponents.DayNight">

parent に指定するMaterialComponentsはどれでも可能です。 詳細はこちらをご覧ください。.

使い方

import { Stripe } from '@capacitor-community/stripe';

await Stripe.createIdentityVerificationSheet({
  ephemeralKeySecret,
  verificationId,
});
const result = await Stripe.presentIdentityVerificationSheet();

🐾 Implements Guide

1. createIdentityVerificationSheet

Props ephemeralKeySecret and verificationId is required. This requires to generate at server side. See Stripe Identity for more details.
https://stripe.com/docs/identity/verify-identity-documents?platform=ios&type=new-integration#create-a-verificationsessionhttps://stripe.com/docs/identity/verify-identity-documents?platform=ios&type=new-integration#create-a-verificationsession

import { Stripe } from '@capacitor-community/stripe';

(async () => {
  // Connect to your backend endpoint, and get every key.
  const { verficationSessionId, ephemeralKeySecret } = await this.http.post<{
    verficationSessionId: string;
    ephemeralKeySecret: string;
  }>(environment.api + 'identify', {}).pipe(first()).toPromise(Promise);

  // prepare IdentityVerificationSheet with createIdentityVerificationSheet.
  await Stripe.createIdentityVerificationSheet({
    ephemeralKeySecret,
    verificationId: verficationSessionId,
  })
})();

You can use options of CreateIdentityVerificationSheetOption on createIdentityVerificationSheet.

method createIdentityVerificationSheet(...)

createIdentityVerificationSheet(options: CreateIdentityVerificationSheetOption) => Promise<void>

Props ephemeralKeySecret and verificationId is required.

interface CreateIdentityVerificationSheetOption

Prop	Type
verificationId	string
ephemeralKeySecret	string

2. presentIdentityVerificationSheet

When you do presentIdentityVerificationSheet method, plugin present PaymentSheet and get result. This method must do after createIdentityVerificationSheet.

(async () => {
  // present IdentityVerificationSheet and get result.
  const result = await Stripe.presentIdentityVerificationSheet()
  if (result.identityVerificationResult === IdentityVerificationSheetEventsEnum.Completed) {
    // Happy path
  }
})();

You can get IdentityVerificationSheetResultInterface from presentIdentityVerificationSheet.

method presentIdentityVerificationSheet()

presentIdentityVerificationSheet() => Promise<{ identityVerificationResult: IdentityVerificationSheetResultInterface; }>

IdentityVerificationSheetResultInterface is created from Enum of IdentityVerificationSheetEventsEnum. So you should import and check result.

type alias IdentityVerificationSheetResultInterface

IdentityVerificationSheetEventsEnum.Completed | IdentityVerificationSheetEventsEnum.Canceled | IdentityVerificationSheetEventsEnum.Failed

enum IdentityVerificationSheetEventsEnum

Members	Value
Loaded	"identityVerificationSheetLoaded"
FailedToLoad	"identityVerificationSheetFailedToLoad"
Completed	"identityVerificationSheetCompleted"
Canceled	"identityVerificationSheetCanceled"
Failed	"identityVerificationSheetFailed"

3. addListener

Method of IdentityVerificationSheet notify any listeners. If you want to get event of IdentityVerificationSheet process is 'Completed', you should add IdentityVerificationSheetEventsEnum.Completed listener to Stripe object:

// be able to get event of IdentityVerificationSheet
Stripe.addListener(IdentityVerificationSheetEventsEnum.Completed, () => {
  console.log('IdentityVerificationSheetEventsEnum.Completed');
});

The event name you can use is IdentityVerificationSheetEventsEnum.

enum IdentityVerificationSheetEventsEnum

Members	Value
Loaded	"identityVerificationSheetLoaded"
FailedToLoad	"identityVerificationSheetFailedToLoad"
Completed	"identityVerificationSheetCompleted"
Canceled	"identityVerificationSheetCanceled"
Failed	"identityVerificationSheetFailed"
