We are integrating 3rd party payment method. When returning from payment channel to return url, the session destroyed.

Any help will be appreciated. Thanks in advanced

Answer 1

You can use this code :

$quote = $objectManager->create('Magento\Quote\Model\QuoteFactory')->create()->load($order->getQuoteId());
 
$quote->setReservedOrderId(null);
$quote->setIsActive(true);
$quote->removePayment();
$quote->save();
$this->checkoutSession->replaceQuote($quote);
$this->cart->setQuote($quote);
$this->checkoutSession->restoreQuote();

NOTE: do not use Object manager, but you need to use the magento standard to implement this code on the place where you want this one.
