Calling APIs on Connect from Java


To call APIs hosted in Connect from Java, you’ll need:

  1. URL for the API endpoint hosted on Connect
  2. API key (if your API requires authorization)

Java example

You can use the url.openConnection method in Java to call APIs from Java applications:


public class RestApi {

    public static void main(String[] args) throws IOException {

        String CONNECT_API_URL = "";
        String CONNECT_API_KEY = "YfB5XBRB7slkkBSEi5qr93mWJvbpXQQy";

        URL url = new URL(CONNECT_API_URL);
        URLConnection urlc = url.openConnection();
        urlc.setRequestProperty("Authorization", "Key " + CONNECT_API_KEY);

        BufferedReader br = new BufferedReader(new InputStreamReader(urlc.getInputStream()));
        String l = null;
        while ((l=br.readLine())!=null) {

You can replace the values of CONNNECT_API_URL and CONNECT_API_KEY with your API URL and API key from Connect.


The code examples assume that you are calling a published API in Connect that is:

  • Hosted on a secure server with TLS/SSL at an HTTPS endpoint
  • Using an API key to make an authorized call to an API
  • Making an HTTP GET request to the API

If your use case is different, then you can modify the example code accordingly.
