Create subscription

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

The code uses our Java gateway class: AfricasTalkingGateway.java [ Download]

To help decode JSON responses, you will need to add one of the available JAVA libraries as a dependency. For this tutorial we chose to use json-20090211.jar which you can download from this repository.

Note On SSL Certificate Validation Issues

Some of our users have experienced SSL Certificate validation issues when connecting to our website due to our use of https. The error you see may look something like this:

Unable to find valid certification path to requested target

Please do not panic! Our certificate is perfectly valid (as evidenced by these verification tests), and the error you are seeing is quite common amongst Java clients connecting to secure websites. Here is how to fix the issue:

  • Download and compile InstallCert.java (you can find the code here).
  • On the CMD prompt(Windows) or Terminal(*nix), run: java InstallCert api.africastalking.com
    This will download a copy of our Certificate and create a file named jssecacerts in the current directory.
  • You can now add our Certificate to your trusted store by copying the created jssecacerts file to the Java security directory under $JAVA_HOME/jre/lib/security
// Make sure the downloaded jar file is in the classpath
public class TestCreateSubscription
{
	public static void main(String[] args) 
	{
		//Specify your credentials
		String username = "myAfricasTalkingUsername";
		String apiKey   = "myAfricasTalkingAPIKey";

		// Specify the number that you want to subscribe
		// Please ensure you include the country code (+254 for Kenya in this case)
		String phoneNumber   = "+254711XXXYYY";
		
		//Specify your Africa's Talking short code and keyword
		String shortCode = "myAfricasTalkingShortCode";
		String keyword   = "myAfricasTalkingKeyword";

		//Create an instance of our awesome gateway class and pass your credentials
		AfricasTalkingGateway gateway = new AfricasTalkingGateway(username, apiKey);

		/*************************************************************************************
			NOTE: If connecting to the sandbox:

			1. Use "sandbox" as the username
			2. Use the apiKey generated from your sandbox application
				https://account.africastalking.com/apps/sandbox/settings/key
			3. Add the "sandbox" flag to the constructor

			AfricasTalkingGateway gateway = new AfricasTalkingGateway(username, apiKey, "sandbox");
		**************************************************************************************/

		// Thats it, submit data and we'll take care of the rest. Any errors will
		// be captured in the Exception class as shown below
		try {
			JSONObject result = gateway.createSubscription(phoneNumber, shortCode, keyword);
			//Only status Success signifies the subscription was successfully
			System.out.println(result.getString("status"));
			System.out.println(result.getString("description"));
		} catch(Exception e){
			System.out.println(e.getMessage());
		}
	}
}
