Mobile Integration Guide

Quick Start

Get your mobile payment integration running in 4 simple steps

Platform Examples

Complete code examples for Android, iOS, React Native, and Flutter

Prerequisites

Before integrating Dodo Payments into your mobile app, ensure you have:

Dodo Payments Account: Active merchant account with API access
API Credentials: API key and webhook secret key from your dashboard
Mobile App Project: Android, iOS, React Native, or Flutter application
Backend Server: To securely handle checkout session creation

Integration Workflow

The mobile integration follows a secure 4-step process where your backend handles API calls and your mobile app manages the user experience.

Backend: Create Checkout Session

Checkout Session API Docs

Learn how to create a checkout session in your backend using Node.js, Python, and more. See complete examples and parameter references in the dedicated Checkout Sessions API documentation.

Security: Checkout sessions must be created on your backend server, never in the mobile app. This protects your API keys and ensures proper validation.

Mobile: Get Checkout URL

Your mobile app calls your backend to get the checkout URL:

iOS (Swift)
Android (Kotlin)
React Native (JavaScript)

func getCheckoutURL(productId: String, customerEmail: String, customerName: String) async throws -> String {
    let url = URL(string: "https://your-backend.com/api/create-checkout-session")!
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    
    let requestData: [String: Any] = [
        "productId": productId,
        "customerEmail": customerEmail,
        "customerName": customerName
    ]
    request.httpBody = try JSONSerialization.data(withJSONObject: requestData)
    
    let (data, _) = try await URLSession.shared.data(for: request)
    let response = try JSONDecoder().decode(CheckoutResponse.self, from: data)
    return response.checkout_url
}

suspend fun getCheckoutURL(productId: String, customerEmail: String, customerName: String): String {
    val client = OkHttpClient()
    val requestBody = JSONObject().apply {
        put("productId", productId)
        put("customerEmail", customerEmail)
        put("customerName", customerName)
    }.toString().toRequestBody("application/json".toMediaType())
    
    val request = Request.Builder()
        .url("https://your-backend.com/api/create-checkout-session")
        .post(requestBody)
        .build()
    
    val response = client.newCall(request).execute()
    val responseBody = response.body?.string()
    val jsonResponse = JSONObject(responseBody ?: "")
    return jsonResponse.getString("checkout_url")
}

const getCheckoutURL = async (productId, customerEmail, customerName) => {
  try {
    const response = await fetch('https://your-backend.com/api/create-checkout-session', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        productId,
        customerEmail,
        customerName
      })
    });
    
    const data = await response.json();
    return data.checkout_url;
  } catch (error) {
    console.error('Failed to get checkout URL:', error);
    throw error;
  }
};

Security: Mobile apps only communicate with your backend, never directly with Dodo Payments API.

Mobile: Open Checkout in Browser

Open the checkout URL in a secure in-app browser for payment processing.

Android Integration

Chrome Custom Tabs Implementation

// Add Chrome Custom Tabs dependency to build.gradle
implementation 'androidx.browser:browser:1.5.0'

// In your Activity
class PaymentActivity : AppCompatActivity() {
    private var customTabsSession: CustomTabsSession? = null
    private var customTabsClient: CustomTabsClient? = null
    private var customTabsServiceConnection: CustomTabsServiceConnection? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        // Initialize Custom Tabs
        customTabsServiceConnection = object : CustomTabsServiceConnection() {
            override fun onCustomTabsServiceConnected(name: ComponentName, client: CustomTabsClient) {
                customTabsClient = client
                customTabsClient?.warmup(0L)
                customTabsSession = customTabsClient?.newSession(object : CustomTabsCallback() {
                    override fun onNavigationEvent(navigationEvent: Int, extras: Bundle?) {
                        // Handle navigation events
                    }
                })
            }
            override fun onServiceDisconnected(name: ComponentName) {
                customTabsClient = null
            }
        }
        CustomTabsClient.bindCustomTabsService(
            this,
            "com.android.chrome",
            customTabsServiceConnection!!
        )
        // Get checkout URL from backend and launch
        lifecycleScope.launch {
            try {
                val checkoutURL = getCheckoutURL("prod_123", "customer@example.com", "Customer Name")
                val customTabsIntent = CustomTabsIntent.Builder(customTabsSession)
                    .build()
                customTabsIntent.launchUrl(this@PaymentActivity, Uri.parse(checkoutURL))
            } catch (e: Exception) {
                // Handle error
                Log.e("PaymentActivity", "Failed to get checkout URL", e)
            }
        }
    }
}

iOS Integration

SFSafariViewController Implementation

import SafariServices
class PaymentViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        Task {
            do {
                let checkoutURL = try await getCheckoutURL(
                    productId: "prod_123",
                    customerEmail: "customer@example.com",
                    customerName: "Customer Name"
                )
                if let url = URL(string: checkoutURL) {
                    let safariVC = SFSafariViewController(url: url)
                    present(safariVC, animated: true, completion: nil)
                }
            } catch {
                // Handle error
                print("Failed to get checkout URL: \(error)")
            }
        }
    }
}

Deep Link Handling

Configure URL schemes to handle payment completion redirects:1. Set up URL schemes in Info.plist:

<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleURLName</key>
    <string>myapp</string>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>myapp</string>
    </array>
  </dict>
</array>

2. Handle redirects in AppDelegate:

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    if url.scheme == "myapp" && url.host == "payment-status" {
        NotificationCenter.default.post(name: .paymentCompleted, object: url)
        return true
    }
    return false
}

3. Listen for payment completion:

NotificationCenter.default.addObserver(self, selector: #selector(handlePaymentCompletion(_:)), name: .paymentCompleted, object: nil)

@objc func handlePaymentCompletion(_ notification: Notification) {
    if let url = notification.object as? URL {
        safariVC?.dismiss(animated: true)
        // Parse payment status from URL parameters
        let components = URLComponents(url: url, resolvingAgainstBaseURL: false)
        let paymentId = components?.queryItems?.first(where: { $0.name == "payment_id" })?.value
        let status = components?.queryItems?.first(where: { $0.name == "status" })?.value
        // Handle payment completion
    }
}

React Native Integration

Using Checkout Links (InAppBrowser)

Open Dodo’s hosted checkout page in an in-app browser.

InAppBrowser Implementation

import React from 'react';
import { View, TouchableOpacity, Text, Alert } from 'react-native';
import { InAppBrowser } from 'react-native-inappbrowser-reborn';

const PaymentButton = ({ productId, onPaymentComplete }) => {
  const openPaymentLink = async () => {
    try {
      // Get checkout URL from backend
      const checkoutURL = await getCheckoutURL(
        productId,
        'customer@example.com',
        'Customer Name'
      );
      
      const result = await InAppBrowser.open(checkoutURL, {
        // iOS options
        dismissButtonStyle: 'cancel',
        preferredBarTintColor: '#453AA4',
        preferredControlTintColor: 'white',
        readerMode: false,
        animated: true,
        modalPresentationStyle: 'fullScreen',
        modalTransitionStyle: 'coverVertical',
        modalEnabled: true,
        enableBarCollapsing: false,
        // Android options
        showTitle: true,
        toolbarColor: '#453AA4',
        secondaryToolbarColor: 'black',
        navigationBarColor: 'black',
        navigationBarDividerColor: 'white',
        enableUrlBarHiding: true,
        enableDefaultShare: true,
        forceCloseOnRedirection: false,
        animations: {
          startEnter: 'slide_in_right',
          startExit: 'slide_out_left',
          endEnter: 'slide_in_left',
          endExit: 'slide_out_right'
        },
        headers: {
          'my-custom-header': 'my custom header value'
        }
      });

      // Handle payment completion based on result
      if (result.type === 'dismiss') {
        // User dismissed the browser
        console.log('Payment browser dismissed');
      }
    } catch (error) {
      Alert.alert('Error', 'Failed to open payment page');
      console.error('InAppBrowser error:', error);
    }
  };

  return (
    <View style={{ padding: 20 }}>
      <TouchableOpacity
        style={{
          backgroundColor: '#007AFF',
          padding: 15,
          borderRadius: 8,
          alignItems: 'center'
        }}
        onPress={openPaymentLink}
      >
        <Text style={{ color: 'white', fontSize: 16, fontWeight: 'bold' }}>
          Pay Now
        </Text>
      </TouchableOpacity>
    </View>
  );
};

export default PaymentButton;

Deep Link Handling for Payment Callbacks

// App.js or your main component
import React, { useEffect } from 'react';
import { Linking } from 'react-native';

const App = () => {
  useEffect(() => {
    // Handle deep links when app is already running
    const handleDeepLink = (url) => {
      if (url.includes('payment-status')) {
        const urlParams = new URLSearchParams(url.split('?')[1]);
        const paymentId = urlParams.get('payment_id');
        const status = urlParams.get('status');
        
        // Handle payment completion
        handlePaymentCallback(paymentId, status);
      }
    };

    // Listen for deep links
    const subscription = Linking.addEventListener('url', ({ url }) => {
      handleDeepLink(url);
    });

    // Handle deep link if app was opened from a link
    Linking.getInitialURL().then((url) => {
      if (url) {
        handleDeepLink(url);
      }
    });

    return () => subscription?.remove();
  }, []);

  const handlePaymentCallback = (paymentId, status) => {
    if (status === 'succeeded') {
      // Navigate to success screen or show success message
      console.log('Payment successful:', paymentId);
    } else {
      // Handle payment failure
      console.log('Payment failed:', paymentId);
    }
  };

  // Your app components...
};

export default App;

Package Dependencies

Add this dependency to your package.json:

{
  "dependencies": {
    "react-native-inappbrowser-reborn": "^6.4.0"
  }
}

Installation Commands

# Install InAppBrowser
npm install react-native-inappbrowser-reborn
cd ios && pod install

Android Configuration

Add to android/app/src/main/AndroidManifest.xml:

<activity
  android:name="com.reactnativeinappbrowserreborn.InAppBrowserActivity"
  android:theme="@style/Theme.AppCompat.Dialog"
  android:exported="false" />

iOS Configuration

Add to ios/YourApp/Info.plist:

<key>CFBundleURLTypes</key>
<array>
  <dict>
    <key>CFBundleURLName</key>
    <string>myapp</string>
    <key>CFBundleURLSchemes</key>
    <array>
      <string>myapp</string>
    </array>
  </dict>
</array>

Use InAppBrowser for native browser experience. Handle deep links for payment callbacks.

Alternative: Native Payment SDK

For a more integrated payment experience with native UI and full customization, Dodo Payments offers a React Native SDK.

Regional Compliance: In-app payment SDKs have regional restrictions. On iOS, native payment SDKs are only legal in the EU (under DMA terms). On Android, they’re legal in User Choice Billing (UCB) markets. For other regions, use the checkout links approach above to ensure App Store and Play Store compliance.

React Native SDK Integration Guide

Review the App Store Fee Bypass Guide to understand regional compliance requirements for in-app payment integrations.

Flutter Integration

import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';
import 'package:http/http.dart' as http;
import 'dart:convert';

Future<String> getCheckoutURL(String productId, String customerEmail, String customerName) async {
  final response = await http.post(
    Uri.parse('https://your-backend.com/api/create-checkout-session'),
    headers: {'Content-Type': 'application/json'},
    body: json.encode({
      'productId': productId,
      'customerEmail': customerEmail,
      'customerName': customerName,
    }),
  );
  
  if (response.statusCode == 200) {
    final data = json.decode(response.body);
    return data['checkout_url'];
  } else {
    throw Exception('Failed to get checkout URL: ${response.statusCode}');
  }
}
class PaymentScreen extends StatefulWidget {
  @override
  _PaymentScreenState createState() => _PaymentScreenState();
}
class _PaymentScreenState extends State<PaymentScreen> {
  late WebViewController _controller;
  String? checkoutURL;
  
  @override
  void initState() {
    super.initState();
    _getCheckoutURL();
  }
  
  Future<void> _getCheckoutURL() async {
    try {
      final url = await getCheckoutURL('prod_123', 'customer@example.com', 'Customer Name');
      setState(() {
        checkoutURL = url;
      });
    } catch (e) {
      // Handle error
      print('Failed to get checkout URL: $e');
    }
  }
  
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Payment')),
      body: checkoutURL == null 
        ? Center(child: CircularProgressIndicator())
        : WebView(
        initialUrl: checkoutURL,
        javascriptMode: JavascriptMode.unrestricted,
        onWebViewCreated: (WebViewController webViewController) {
          _controller = webViewController;
        },
        navigationDelegate: (NavigationRequest request) {
          if (request.url.contains('payment_id') && request.url.contains('status')) {
            // Handle payment completion
            final uri = Uri.parse(request.url);
            final paymentId = uri.queryParameters['payment_id'];
            final status = uri.queryParameters['status'];
            handlePaymentCompletion(paymentId, status);
            return NavigationDecision.prevent;
          }
          return NavigationDecision.navigate;
        },
      ),
    );
  }
  void handlePaymentCompletion(String? paymentId, String? status) {
    if (status == 'succeeded') {
      // Payment successful
    } else {
      // Payment failed
    }
  }
}

Use WebView for payment links. Handle the redirect URL to detect payment completion.

Best Practices

Security: Never store API keys in your app code. Use secure storage and SSL pinning.
User Experience: Show loading indicators, handle errors gracefully, and provide clear messages.
Testing: Use test cards, simulate network errors, and test on various devices.

Troubleshooting

Common Issues

WebView not opening payment link: Ensure the payment link is valid and uses HTTPS.
Callback not received: Check your return URL and webhook configuration.
API key errors: Verify that your API key is correct and has the necessary permissions.
