Fetch premium subscriptions

You need your AfricasTalking username and APIKey for any request to our API. If you don't have an APIKey, you can generate one from your applications settings page.

The VB code snippet below shows how to add a number to a subscription service using our API.

The code uses our VB gateway class: AfricasTalkingGateway.vb [ Download]

Imports System.IO
Imports System.Collections
Imports System.Collections.Generic

Public Class Application
	Public Shared Sub Main()
			' Specify your login credentials
			Dim username As String = "MyAppUsername"
			Dim apikey As String   = "myAPIKey"
			' Specify your premium shortcode and keyword
			Dim shortCode As String = "XXXXX";
			Dim keyword As String = "myPremiumKeyword";
			' Create a new instance of our awesome gateway class
			Dim gateway As 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 number we sent you
			' on subsequent results
			Dim lastReceivedId As Integer = 0;
			' Any gateway errors will be captured by our custom Exception class below,
			' so wrap the call in a try-catch block
			 Dim subscriptions As Object() = gateway.fetchPremiumSubscriptions(shortCode, keyword, lastReceivedId)
			 While subscriptions.Length > 0
			 	Dim result As Object
			 	for each result in subscriptions
			 		System.Console.WriteLine("Phone number: " + result("phoneNumber"))
			 		lastReceivedId = result("id")
			 	subscriptions = gateway.fetchPremiumSubscriptions(shortCode, keyword, lastReceivedId)
			 End While
		catch ex As AfricasTalkingGatewayException
		End Try 
	End Sub
End Class
