How to send an API request to TestRail to update the status as passed .

For that I used Rest Assured with Java and below code snippet.

import io.restassured.RestAssured;
import io.restassured.response.Response;
import org.json.JSONObject; 

public void sendTestResultOfTestCase() {
        String username = "myusername";
        String password = "mypassword";
        String runId = "29798"; //Remove the starting English letter R29798 , so it's 29798
        String testCaseId = "1827330"; // Remove the starting English letter
        String endpoint = "https://skynet.testrail.net/index.php?/api/v2/add_result_for_case/" + runId + "/" + testCaseId;
        JSONObject requestParams = new JSONObject();

        requestParams.put("status_id", "1");    // 1 means pass
        requestParams.put("comment", "Hi, this test was passed via automation."); // optional comment.
        requestParams.put("case_id", testCaseId);
        requestParams.put("run_id", runId);
        Response response = RestAssured.given().auth().preemptive().basic(username, password)
                .contentType("application/json")
                .body(requestParams.toString())
                .when()
                .post(endpoint);
        System.out.println(response.getBody().asString());


    }

1 means pass and two means blocked, 4 means retest and 5 means fail.
