I want to set custom pricing for magento2 product through API . I googled for the same and tried to implement the solutions one by one. But no solution is worked out.

$cartId = $this->cartManagementInterface->createEmptyCartForCustomer($customer_id); //Create empty cart
$quote = $this->cartRepositoryInterface->get($cartId);

I am getting error on creating empty cart for customer.

"Warning: Illegal offset type in isset or empty in /var/www/html/mypro/vendor/magento/module-quote/Model/QuoteRepository.php on line 133"

Can any one help me on this? I am adding complete code that i am trying. Please help me on this.

class PoApi implements PosApiInterface

 public function __construct(
 MagentoFrameworkAppRequestInterface $request,
 MagentoFrameworkObjectManagerInterface $objectManager,
 MyRequestToQuoteModelQuote $quote,
 MyRequestToQuoteModelQuoteDetail $qdetails,
 MyRequestToQuoteModelPo $po,
 MyVincrequestModelVpo $vpo,
 MyRequestToQuoteModelPoDetail $podetails,
 MagentoQuoteApiCartRepositoryInterface $cartRepositoryInterface,
 MagentoQuoteApiCartManagementInterface $cartManagementInterface,
 MagentoFrameworkRegistry $registry,
 MagentoFrameworkUrlInterface $urlinterface,
 MagentoCustomerApiCustomerRepositoryInterfaceFactory $customerRepositoryFactory
 ) 
 $this->_request = $request;
 $this->_objectManager = $objectManager;
 $this->_quote = $quote;
 $this->_quotedetails = $qdetails;
 $this->_po = $po;
 $this->_vpo = $vpo;
 $this->_podetails = $podetails;
 $this->_coreRegistry = $registry;
 $this->_urlBuilder = $urlinterface;
 $this->_customerRepository = $customerRepositoryFactory;
 $this->cartRepositoryInterface=$cartRepositoryInterface;
 $this->cartManagementInterface=$cartManagementInterface;
 

 public function poToCart($poid)
 
 try $status == '0') 
 $poData->setData('status', '1');
 $poData->save();

 $podetail = $poData->getCollection()->addFieldToFilter('po_increment_id', $po_incId)->addFieldToFilter('status', '1')->getData();

 if (sizeof($podetail)>0) 
 $poProd=$this->_objectManager->create('MyCrequestModelPoDetail')->getCollection()->addFieldToFilter('po_id', $po_incId)->getData();


 $cartId = $this->cartManagementInterface->createEmptyCart(); //Create empty cart
 $quote = $this->cartRepositoryInterface->get($cartId); // load empty cart quote
 $quote->setStore($store);
 // if you have allready buyer id then you can load customer directly
 $customer= $this->customerRepository->getById($customer->getEntityId());
 $quote->setCurrency();
 $quote->assignCustomer($customer); //Assign quote to customer

 //add items in quote
 foreach ($poProd as $item) 
 $product=$this->_product->load($item['product_id']);
 $product->setPrice($item['po_price']);
 $quote->addProduct($product, intval($item['product_qty']));
 

 $quote->save(); //Now Save quote and your quote is ready

 return "Added Cart";
 
 
 catch (Exception $ex) 
 return $ex->getMessage();
 
 

When i tried to call this API. I am getting below error message.

MagentoFrameworkExceptionCouldNotSaveException: Cannot create quote in /var/www/html/myproj/vendor/magento/module-quote/Model/QuoteManagement.php:239
Stack trace:
#0 /var/www/html/myproj/app/code/My/Crequest/Model/PoApi.php(316): MagentoQuoteModelQuoteManagement->createEmptyCart()
#1 [internal function]: MyCrequestModelPoApi->poToCart('PO000101')

I tried another code as well by hitting API programmatically.

$store=$this->_storeManager->getStore();
$repository = $this->_objectManager->create(MagentoCustomerApiCustomerRepositoryInterface::class);
/** @var $customer MagentoCustomerApiDataCustomerInterface */
$customer = $repository->getById(2);
$customerId = $customerObj->getId();

$serviceInfo = [
 'rest' => [
 'resourcePath' => '/V1/customers/' . $customerId . '/carts',
 'httpMethod' => MagentoFrameworkWebapiRestRequest::HTTP_METHOD_POST,
 ]
];

echo $quoteId = $this->_webApiCall($serviceInfo, ['customerId' => $customerId]);

But this is also giving an error like below.

 Uncaught Error: Call to undefined method MyCrequestModelPoApi::_webApiCall() in

Try this:

$customer = $this->_customerRepository->getById($customerId);
$quote = $this->_quoteFactory->create();
$quote->setStoreId($storeId);
$quote->assignCustomer($customer);

I tried below code , Now i am able to add product to customer cart finely but it is showing price as 0.

 $store=$this->_storeManager->getStore();
 $cartId = $this->cartManagementInterface->createEmptyCartForCustomer($poData->getPoCustomerId()); //Create empty cart
 $quote = $this->cartRepositoryInterface->get($cartId); // load empty cart quote
 $quote->setStore($store);
 // if you have allready buyer id then you can load customer directly 
 $customer= $this->_customerRepository->getById($poData->getPoCustomerId());
 $quote->setCurrency();
 $quote->assignCustomer($customer); //Assign quote to customer

 //add items in quote
 foreach($poProd as $item)
 //$product=$this->_product->load($item['product_id']);
 $product = $this->_objectManager->create ( 'MagentoCatalogModelProduct' )->load ( $item['product_id']);
 $product->setPrice($item['po_price']);
 $quote->addProduct($product, intval($item['product_qty']));
 

 $quote->save(); //Now Save quote and your quote is ready

 return "Added Cart";

I am getting the below response from post man when i access V1/carts/mine/items
