API Running for one user and not for other

API Running for one user and not for other

Hello, I created a WordPress plugin using the PHP SDK provided by Zoho, and everything works fine with my account. However, when I change the details like Client ID, Client Secret, refresh token, and User Email, the plugin stops working. I checked my entire code, and I only need to change these details. Also, if there is an issue with my code, I don't think it should be working with my details, so please let me know what I'm missing 

And here is my code 

use com\zoho\api\authenticator\OAuthBuilder;
use com\zoho\crm\api\dc\USDataCenter;
use com\zoho\crm\api\InitializeBuilder;
use com\zoho\crm\api\UserSignature;
use com\zoho\crm\api\record\APIException;
use com\zoho\api\authenticator\store\TokenStore;
use com\zoho\api\authenticator\store\FileStore;
use com\zoho\crm\api\record\BodyWrapper;
use com\zoho\crm\api\record\RecordOperations;
use com\zoho\crm\api\record\Record;
use com\zoho\crm\api\users\User;

require_once "vendor/autoload.php";

add_action('user_register', 'send_data_to_zoho_crm', 10, 1);

// Create directory for token storage
register_activation_hook(__FILE__, 'zoho_crm_integration_activate');

function zoho_crm_integration_activate() {
    $token_directory = plugin_dir_path(__FILE__) . 'tokens.txt';

    if (!file_exists($token_directory)) {
        wp_mkdir_p($token_directory);
    }
}

function send_data_to_zoho_crm($user_id) {
    // Schedule the function to run 5 seconds later
    wp_schedule_single_event(time() + 5, 'zoho_crm_integration_send_data', [$user_id]);
}

add_action('zoho_crm_integration_send_data', 'zoho_crm_integration_send_data_now', 10, 1);

function zoho_crm_integration_send_data_now($user_id) {
    $moduleAPIName = "Accounts";
    $user_info = get_userdata($user_id);
    $phone = get_user_meta($user_id, '___META FIELD_____', true);

   


    $createRecords = new CreateRecords();
    $createRecords->createRecords($moduleAPIName,
        $user_info->first_name,
        $user_info->last_name,
        $user_info->user_email,
        $phone
    );

}

class CreateRecords
{
    public function __construct()
    {
        $user = new UserSignature('_____User Email ID_____');
        $environment = USDataCenter::PRODUCTION();
        $token = (new OAuthBuilder())
            ->clientId("_____Client Id_____")

            ->build();
        $tokenstore = new FileStore(plugin_dir_path(__FILE__) . 'tokens.txt'); // File storage for tokens
        (new InitializeBuilder())
            ->user($user)
            ->environment($environment)
            ->token($token)
            ->store($tokenstore)
            ->initialize(); // Use the initialize() method
    }

    public function createRecords(
        string $moduleAPIName,
        string $first_name,
        string $last_name,
        string $user_email,
        string $phone
    ) {
        $recordOperations = new RecordOperations();
        $bodyWrapper = new BodyWrapper();
        $recordInstance = new Record();
        $current_datetime = date('Y-m-d\TH:i:sP');
        $recordInstance->addKeyValue("First_Name", $first_name);
        $recordInstance->addKeyValue("Last_Name", $last_name);
        $recordInstance->addKeyValue("Phone_1", $phone);


        $bodyWrapper->setData([$recordInstance]);
        try {
            $response = $recordOperations->createRecords($moduleAPIName, $bodyWrapper);
            error_log("API response: " . print_r($response, true));
        } catch (APIException $exception) {
            error_log("APIException: " . print_r($exception, true));
        } catch (\Exception $exception) {
            error_log("Exception: " . $exception->getMessage());
        }
    }
}
