Not able to authenticate with API Key

I am expecting authentication process to zephyr squad public api server, tried with Java or Typescript still getting unauthorized error. Do we need JWT or API access key can help in authentication

TypeScript code used for JWT

import { chromium } from 'playwright';
import jwt from 'jsonwebtoken';
import * as fs from 'fs';
import * as path from 'path';

async function generateJwt() {
    // Replace Zephyr BaseUrl with the <ZAPI_CLOUD_URL> shared with ZAPI Cloud Installation
    const zephyrBaseUrl = '<ZAPI_CLOUD_URL>';
    // zephyr accessKey and secretKey, obtained from Addons >> zapi section
    const accessKey = 'YjE2MjdjMGEtNzExNy0zYjY1LWFkMzQtNjcwMDM3IGI0NjI3YzBhLTUxMTctMzM2NS1hZDM0IGFkbWlu';
    const secretKey = 'qufnbimi96Ob2hq3ISF08yZ8nUvDRHmQwHGeGlk';
    const accountId = 'accountId'; // Jira accountId

    // Create a JWT token
    const expirationInSec = 360; // Token expiration time in seconds
    const createCycleUri = `${zephyrBaseUrl}/public/rest/api/1.0/cycle?expand=&clonedCycleId=`;

    const payload = {
        // JWT payload can include any required data
        accountId,
        uri: createCycleUri,
    };

    const token = jwt.sign(payload, secretKey, { expiresIn: expirationInSec });

    // Print the URL and JWT token to be used for making the REST call
    console.log('FINAL API : ' + createCycleUri);
    console.log('JWT Token : ' + token);
}

// Run the function
generateJwt().catch(err => console.error('Error generating JWT:', err));
