Creating an instance variable that represents other variables with same names but unique values in different classes (Java)

I am currently attempting to integrate automated tests with our test management tool with the use of APIs. Each test(which is contained in a single class) has a unique id which needs to be referenced in the API call. I can either declare the Test IDs in the tests themselves (preferred) or create a separate class that contains all of the IDs for reference. The issue I am having is coming up with a good way to represent these IDs as a variable when the particular test is run, so I do not a have to repeat the API framework for each unique ID.

Here is the general set up of the API class/listener class.

  package testPackage;

import java.io.IOException;
import java.net.MalformedURLException;
import java.util.HashMap;
import java.util.Map;

import org.json.simple.JSONObject;
import org.testng.ITestResult;
import org.testng.TestListenerAdapter;

import com.gurock.testrail.APIClient;
import com.gurock.testrail.APIException;


public class MyTestResultsListener extends TestListenerAdapter {

    public final APIClient client = new APIClient("https://api.url/");
    public final Map data = new HashMap();

    public final void APISendCredentials() {
        client.setUser("username");
        client.setPassword("password");


    }

    @Override
    public void onTestFailure(ITestResult result) {
        APISendCredentials();
        data.put("status_id", new Integer(5));
        data.put("comment", "This test failed");
        try {
            JSONObject r = (JSONObject) client.sendPost("add_result_for_case/" + "Unique ID", data);
        } catch (MalformedURLException e) {

            e.printStackTrace();
        } catch (IOException e) {

            e.printStackTrace();
        } catch (APIException e) {

            e.printStackTrace();
        }
    }

    @Override
    public void onTestSuccess(ITestResult result) {
        APISendCredentials();
        data.put("status_id", new Integer(1));
        data.put("comment", "This test passed");
        try {
            JSONObject r = (JSONObject) client.sendPost("add_result_for_case/" + TestClass.AutomationID, data);
        } catch (MalformedURLException e) {

            e.printStackTrace();
        } catch (IOException e) {

            e.printStackTrace();
        } catch (APIException e) {

            e.printStackTrace();
        }

    }

    @Override
    public void onTestSkipped(ITestResult result) {
        APISendCredentials();
        data.put("status_id", new Integer(2));
        data.put("comment", "This test was blocked or skipped");
        try {
            JSONObject r = (JSONObject) client.sendPost("add_result_for_case/" + TestClass.AutomationID, data);
        } catch (MalformedURLException e) {

            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (APIException e) {
            e.printStackTrace();
        }

    }
}

Test class

package testPackage;

import java.io.IOException;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import java.lang.reflect.Method;
import java.net.MalformedURLException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.Assert;
import org.testng.annotations.AfterTest;
import org.testng.annotations.Listeners;
import org.testng.annotations.Test;
import com.gurock.testrail.APIException;

@Listeners(MyTestResultsListener.class)

public class TestClass {

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface TestData {
    String testId() default "0";

}

public static String AutomationID = "236/50819";

@Test
@TestData(testId = "236/50819")
public void test1() {
    //sometest 

}

@AfterTest
public void aftertest() {
    //This was my initial blind attempt at reflection. I am getting 
    //an error below stating "test1" cannot be resolved to a variable 
    //also unclear on how to feed this to the APIclass 
    Method testMethod = getClass().getMethod(test1);
    if (testMethod.isAnnotationPresent(TestData.class)) {
        TestData testData = testMethod.getAnnotation(TestData.class);
        //stuck at this point 
    }
}

}

As you can see on the lines that start with JSONobject r I have a place holder for the uniqueID variable. What would be the best way/most efficient way to create a variable that could take these unqiue IDs from the different test classes ?

Thx, let me know if there is any additional information needed that would be helpful !
