How to generate encrypted cartid to access the Rest API guest cart - Magento 2

Question

I get quote id from below code it returns 6 as my quote id

$id=$this->_checkoutSession->getQuoteId();

I used the quote_id=6 in REST api like rest/default/V1/guest-carts/6/estimate-shipping-methods

It throws the below error in Postman

{ "message": "No such entity with %fieldName = %fieldValue", "parameters": { "fieldName": "cartId", "fieldValue": 0 } }

I have checked frontend cart page actual cart id seems encrypted rest/default/V1/guest-carts/6vf0uVP3A3RNBbTDPe4ECKxjDrJw44lO/estimate-shipping-methods

could you please anyone enlighten me? Thanks.

syntax

rest/default/V1/guest-carts/:cartId/estimate-shipping-methods

In the checkout session you can able to find the masked quote in js itself.

window.checkoutConfig.quoteData.entity_id for guest user.

For Examle

if window.checkoutConfig.quoteData.entity_id is digit means

 `customer is logged in` 

else

 `guest session` there you can find the masked quote id

For generating the Masked Quote id

inject the \Magento\Quote\Model\QuoteIdMaskFactory

$quoteIdMask = $this->quoteIdMaskFactory->create()->load(YOUR_QUOTE_ID, 'quote_id'); $id = $quoteIdMask->getMaskedId();
