Magento 2 API Get Customer Cart Data using customer ID

Question

I am building custom magento 2 API. I want to get customer CART DATA using CUSTOMER_ID. I am doing this to serve magento data into android and ios customer devices.

I have tried following code but its not working.

$params = $this->request->getPostValue();
$customerId = $params["customer_id"];
        
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$customerData = $objectManager->create('Magento\Customer\Model\Customer')->load($customerId);

//Code to get customer cart data
$quote = $this->quoteFactory->create();
$customerQuote=$this->quoteModel->loadByCustomerId($quote,$customerId); // where `$customerId` is your `customer id`
return $items = $customerQuote->getAllItems();
    

For security concern, I am passing custom permanent token and customer id.

I have also tried many other sample codes but they are not working anyone can help me here. Thanks

I am assuming you are passing customer id into POST method. Can you try following ?

Add following requirements

...
use Magento\Quote\Model\QuoteFactory;
...
protected $quoteFactory;
...


 public function __construct(
 ...
 \Magento\Quote\Model\QuoteFactory $quoteFactory,
 ...
){
 ...
 $this->quoteFactory = $quoteFactory;
 ...
 }

try following function

public function getCart() {

    $params = $this->request->getPostValue();
    $customerId = $params["customer_id"];
    
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $customerObj = $objectManager->create('Magento\Customer\Model\Customer')->load($customerId);
    
    $customerFirstName = $customerObj->getFirstname();
    $customerFirstName = $customerObj->getLastname(); 
    
    $quote = $this->quoteFactory->create()->loadByCustomer($customerObj);
    
    $items = $quote->getAllItems();
    
    $cart_data = array();
    foreach($items as $item)
    {
        $cart_data[] = array(
            'name'=> $item_data['name'],
            'product_id'=> $item_data['product_id'],
            'price'=>$item_data['price'],                               
            'qty'=> $item_data['qty'],
        );
    } 
    
    return $cart_data;
    
}
