iOS presentExternalPurchaseLinkIOS

Open an external purchase URL outside the app (iOS 16+).

Opens the URL via UIApplication.open(_:options:completionHandler:) after a canOpenURL guard — the openiap-apple implementation routes through UIKit rather than StoreKit's ExternalPurchaseLink API. The native call must still be gated by the StoreKit external-purchase entitlement on production builds. See the Apple UIApplication.open reference.

Signature

swift

func presentExternalPurchaseLinkIOS(_ url: String) async throws -> ExternalPurchaseLinkResultIOS

struct ExternalPurchaseLinkResultIOS {
    let error: String?
    let success: Bool
}

Kotlin example

suspend fun presentExternalPurchaseLinkIOS(url: String): ExternalPurchaseLinkResultIOS

TypeScript example

presentExternalPurchaseLinkIOS(url: string): Promise<ExternalPurchaseLinkResultIOS>

Dart example

dart

Future<ExternalPurchaseLinkResultIOS> presentExternalPurchaseLinkIOS(String url);

C# (MAUI) example

Task<ExternalPurchaseLinkResultIOS> PresentExternalPurchaseLinkIOSAsync(string url);

GDScript example

func present_external_purchase_link_ios(url: String) -> Variant

Parameters#

url (required, string) — External purchase URL to present.

Promise<ExternalPurchaseLinkResultIOS> — carries the result of opening the external link (success flag + any error message).

Example

swift

let result = try await OpenIapModule.shared.presentExternalPurchaseLinkIOS("https://yourstore.com/checkout")

Kotlin example

import { presentExternalPurchaseLinkIOS } from 'expo-iap';

if (Platform.OS === 'ios') {
  await presentExternalPurchaseLinkIOS('https://yourstore.com/checkout');
}

  await FlutterInappPurchase.instance
      .presentExternalPurchaseLinkIOS('https://yourstore.com/checkout');
