Code Examples | Pushblitz Docs

Here are examples of how to send the subscription request from various environments once you have successfully obtained the device token.

cURL

curl -X POST https://api.pushblitz.com/subscribe \
  -H "Content-Type: application/json" \
  -H "X-Channel-ID: 123e4567-e89b-12d3-a456-426614174000" \
  -d '{
    "platform": "ios",
    "provider_token": "a1b2c3d4e5f6g7h8i9j0...",
    "attributes": {
        "user_language": "en"
    }
  }'

Swift (iOS Native)

Once you receive the APNS deviceToken in didRegisterForRemoteNotificationsWithDeviceToken, convert it to a hex string and send it to Pushblitz.

func registerPushblitzToken(apnsToken: String) {
    let url = URL(string: "https://api.pushblitz.com/subscribe")!
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    request.setValue("123e4567-e89b-12d3-a456-426614174000", forHTTPHeaderField: "X-Channel-ID")
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    
    let payload: [String: Any] = [
        "platform": "ios",
        "provider_token": apnsToken
    ]
    
    request.httpBody = try? JSONSerialization.data(withJSONObject: payload)
    
    URLSession.shared.dataTask(with: request) { data, response, error in
        if let error = error {
            print("Pushblitz registration failed: \(error)")
            return
        }
        print("Pushblitz registration successful!")
    }.resume()
}

Kotlin (Android Native)

Once you retrieve the FCM token via FirebaseMessaging.getInstance().token, send it to Pushblitz.

fun registerPushblitzToken(fcmToken: String) {
    val url = URL("https://api.pushblitz.com/subscribe")
    val connection = url.openConnection() as HttpURLConnection
    connection.requestMethod = "POST"
    connection.setRequestProperty("X-Channel-ID", "123e4567-e89b-12d3-a456-426614174000")
    connection.setRequestProperty("Content-Type", "application/json")
    connection.doOutput = true
    
    val payload = """
        {
            "platform": "android",
            "provider_token": "$fcmToken"
        }
    """.trimIndent()
    
    connection.outputStream.use { os ->
        val input = payload.toByteArray(Charsets.UTF_8)
        os.write(input, 0, input.size)
    }
    
    val responseCode = connection.responseCode
    println("Pushblitz Response Code: $responseCode")
}

React Native (Fetch API)

If you are using a cross-platform framework, your code handles both conditionally.

const registerWithPushblitz = async (token, platform) => {
  // 'token' is your FCM or APNS token
  // 'platform' should be 'ios' or 'android'
  
  try {
    const response = await fetch('https://api.pushblitz.com/subscribe', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'X-Channel-ID': '123e4567-e89b-12d3-a456-426614174000',
      },
      body: JSON.stringify({
        platform: platform,
        provider_token: token,
      }),
    });
    
    const data = await response.json();
    console.log('Pushblitz registration:', data);
  } catch (error) {
    console.error('Error registering to Pushblitz:', error);
  }
};

Flutter (Dart)

In Flutter, after obtaining the device token via firebase_messaging or apns, you can send it to Pushblitz using the standard http package.

import 'dart:convert';
import 'package:http/http.dart' as http;

Future<void> registerWithPushblitz(String token, String platform) async {
  // 'token' is your FCM or APNS token
  // 'platform' should be 'ios' or 'android'
  
  final url = Uri.parse('https://api.pushblitz.com/subscribe');
  
  try {
    final response = await http.post(
      url,
      headers: {
        'Content-Type': 'application/json',
        'X-Channel-ID': '123e4567-e89b-12d3-a456-426614174000',
      },
      body: jsonEncode({
        'platform': platform,
        'provider_token': token,
      }),
    );
    
    if (response.statusCode == 200 || response.statusCode == 201) {
      print('Pushblitz registration successful: ${response.body}');
    } else {
      print('Pushblitz registration failed: ${response.statusCode} - ${response.body}');
    }
  } catch (e) {
    print('Error registering to Pushblitz: $e');
  }
}
