Calling APIs on Connect from Java
Requirements
To call APIs hosted in Connect from Java, you’ll need:
- URL for the API endpoint hosted on Connect
 - API key (if your API requires authorization)
 
Java example
You can use the url.openConnection method in Java to call APIs from Java applications:
import java.io.*;
import java.net.*;
public class RestApi {
    public static void main(String[] args) throws IOException {
        String CONNECT_API_URL = "https://connect.yourcompany.com/rest-api-example/endpoint";
        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) {
            System.out.println(l);
        }
        br.close();
    }
}You can replace the values of CONNNECT_API_URL and CONNECT_API_KEY with your API URL and API key from Connect.
Scope
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.
