**On this pageIonicIntegrate the Human Token Journey into your Ionic app using a Capacitor plugin.

The integration uses a local Capacitor plugin that delegates to Custom Tabs on Android and `ASWebAuthenticationSession` on iOS. When the journey finishes, the deep link returns through `@capacitor/app`.
### Prerequisites​

Ionic with Capacitor v4+
`@capacitor/app` installed
Xcode 14+ and Android Studio
A unique URL scheme for your app (e.g. `myapp`)

### Step 1: Define your URL scheme​

Choose a unique scheme (e.g. `myapp`). This is used as the `callbackUri` when creating the process:
```
callbackUri: myapp://callback
```

### Step 2: Create the Capacitor plugin interface​

```
import { registerPlugin } from '@capacitor/core';export interface UnicoPlugin {  openSession(options: { url: string }): Promise<{ callbackUrl: string }>;}const Unico = registerPlugin<UnicoPlugin>('UnicoPlugin');export default Unico;
```

### Step 3: Implement the iOS plugin​

```
import Capacitorimport AuthenticationServices@objc(UnicoPlugin)public class UnicoPlugin: CAPPlugin, ASWebAuthenticationPresentationContextProviding {    private var session: ASWebAuthenticationSession?    @objc func openSession(_ call: CAPPluginCall) {        guard let urlString = call.getString("url"),              let url = URL(string: urlString) else {            call.reject("Invalid URL")            return        }        DispatchQueue.main.async {            let newSession = ASWebAuthenticationSession(                url: url,                callbackURLScheme: "myapp"            ) { callbackURL, error in                self.session = nil                if let callbackURL = callbackURL {                    call.resolve(["callbackUrl": callbackURL.absoluteString])                } else {                    call.reject(error?.localizedDescription ?? "Session cancelled")                }            }            newSession.presentationContextProvider = self            newSession.prefersEphemeralWebBrowserSession = true            newSession.start()            self.session = newSession        }    }    public func presentationAnchor(for session: ASWebAuthenticationSession) -> ASPresentationAnchor {        guard let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene,              let window = windowScene.windows.first else {            return ASPresentationAnchor()        }        return window    }}
```

### Step 4: Implement the Android plugin​

```
import android.content.Intentimport android.net.Uriimport androidx.browser.customtabs.CustomTabsIntentimport com.getcapacitor.Pluginimport com.getcapacitor.PluginCallimport com.getcapacitor.PluginMethodimport com.getcapacitor.annotation.CapacitorPlugin@CapacitorPlugin(name = "UnicoPlugin")class UnicoPlugin : Plugin() {    private var pendingCall: PluginCall? = null    @PluginMethod    fun openSession(call: PluginCall) {        val url = call.getString("url") ?: return call.reject("Missing URL")        pendingCall = call        activity.runOnUiThread {            CustomTabsIntent.Builder().build()                .launchUrl(activity, Uri.parse(url))        }    }    override fun handleOnNewIntent(intent: Intent) {        super.handleOnNewIntent(intent)        intent.data?.let { uri ->            if (uri.scheme == "myapp") {                pendingCall?.resolve(com.getcapacitor.JSObject().put("callbackUrl", uri.toString()))                pendingCall = null            }        }    }}
```

### Step 5: Configure URL schemes​

iOSAndroidAdd to `Info.plist`:```
<key>CFBundleURLTypes</key><array>    <dict>        <key>CFBundleURLSchemes</key>        <array>            <string>myapp</string>        </array>    </dict></array>
```

Add to `AndroidManifest.xml` inside your main `<activity>`:```
<intent-filter>    <action android:name="android.intent.action.VIEW" />    <category android:name="android.intent.category.DEFAULT" />    <category android:name="android.intent.category.BROWSABLE" />    <data android:scheme="myapp" android:host="callback" /></intent-filter>
```

Add to `build.gradle`:```
implementation("androidx.browser:browser:1.5.0")
```

### Step 6: Create the Angular service​

```
import { Injectable } from '@angular/core';import Unico from '../plugins/unico-plugin';@Injectable({ providedIn: 'root' })export class UnicoService {  async openSession(url: string): Promise<string | null> {    try {      const result = await Unico.openSession({ url });      const params = new URL(result.callbackUrl).searchParams;      return params.get('id');    } catch {      return null;    }  }}
```

### Step 7: Listen for deep links​

In your `AppComponent`:
```
import { App } from '@capacitor/app';App.addListener('appUrlOpen', (event) => {  // Handle the callback URL if needed  console.log('Deep link received:', event.url);});
```
