Fetch premium subscriptions

You need your AfricasTalking username and APIKey for any request to our API. If you don't have an APIKey, please click here to get one.

The C# code snippet below shows how to fetch subscribed numbers from a subscription service using our API.

The code uses our C# gateway class: AfricasTalkingGateway.cs [ Download]

To help decode JSON responses, you will need to add a reference to System.Web.Extensions and System.Microsoft.CSharp

using System;

class MainClass
{
	static public void Main (){
	
		// Specify your login credentials
		string username = "MyAfricasTalkingUsername";
		string apiKey   = "MyAfricasTalkingAPIKey";
		
		// Specify your premium shortcode and keyword
		string shortCode = "XXXXX";
		string keyword   = "myPremiumKeyword";
		
		// Create a new instance of our awesome gateway class
		AfricasTalkingGateway gateway = new AfricasTalkingGateway (username, apiKey);
		
		// Our gateway will return 100 subscription numbers at a time back to you, starting with
		// what you currently believe is the lastReceivedId. Specify 0 for the first
		// time you access the gateway, and the ID of the last message we sent you
		// on subsequent results
		
		int lastReceivedId = 0;

		// Any gateway errors will be captured by our custom Exception class below,
		// so wrap the call in a try-catch block   
		try {
			// Here is a sample of how to fetch all messages using a while loop     
			do {
	        	
				dynamic results = gateway.fetchPremiumSubscriptions(shortCode, keyword, lastReceivedId);

				foreach(dynamic result in results) {
					Console.WriteLine("phoneNumber: " + result["phoneNumber"]);
					lastReceivedId = (int)result["id"];
				}
			} while ( results.Count > 0 );

		} catch (AfricasTalkingGatewayException e) {

			Console.WriteLine ("Encountered an error: " + e.Message);		

		}
}
