I want to make order id as Transaction id for Order via credit card/debit card.

Now, random ID generated. Below is the code.

namespace PayUIndia\Payu\Model;

use Magento\Sales\Api\Data\TransactionInterface;

class Payu extends \Magento\Payment\Model\Method\AbstractMethod {

    const PAYMENT_PAYU_CODE = 'payu';
    const ACC_BIZ = 'payubiz';
    const ACC_MONEY = 'payumoney';

    protected $_code = self::PAYMENT_PAYU_CODE;

    /**
     *
     * @var \Magento\Framework\UrlInterface 
     */
    protected $_urlBuilder;
    protected $_supportedCurrencyCodes = array(
        'AFN', 'ALL', 'DZD', 'ARS', 'AUD', 'AZN', 'BSD', 'BDT', 'BBD',
        'BZD', 'BMD', 'BOB', 'BWP', 'BRL', 'GBP', 'BND', 'BGN', 'CAD',

I guess that you need to change

$params["txnid"] = substr(hash('sha256', mt_rand() . microtime()), 0, 20);

to

$params["txnid"] = $order->getIncrementId();

Change below code:

$params["txnid"] = substr(hash('sha256', mt_rand() . microtime()), 0, 20);

By

$params["txnid"] = $this->checkoutSession->getLastRealOrderId();
