Magento 2 : How to get Shipping Methods for Specific Customer Group

 To get the available shipping methods for a specific customer group in Magento 2, you can follow these steps:

1. Inject the necessary dependencies in your class constructor or method. You will need the following dependencies:

phpCopy code
use MagentoCustomerApiGroupRepositoryInterface;
use MagentoQuoteApiShippingMethodManagementInterface;
use MagentoQuoteModelQuoteAddressRateCollectorInterface;

2. Create class properties for the injected dependencies:

phpCopy code
protected $groupRepository;
protected $shippingMethodManagement;
protected $rateCollector;

3. Initialize the dependencies in the constructor:

phpCopy code
public function __construct(
    GroupRepositoryInterface $groupRepository,
    ShippingMethodManagementInterface $shippingMethodManagement,
    RateCollectorInterface $rateCollector
) {
    $this->groupRepository = $groupRepository;
    $this->shippingMethodManagement = $shippingMethodManagement;
    $this->rateCollector = $rateCollector;
}

4. Use the following code to retrieve the available shipping methods for a specific customer group:

phpCopy code
$customerGroupId = 1; // Replace with the desired customer group ID

try {
    $group = $this->groupRepository->getById($customerGroupId);
    $rateRequest = $this->rateCollector->createRateRequest();
    $rateRequest->setAllItems([]);
    $rateRequest->setDestCountryId('US'); // Replace with the desired country ID
    $rateRequest->setDestPostcode('12345'); // Replace with the desired postal code
    $rateRequest->setCustomerGroupId($group->getId());

    $shippingMethods = $this->shippingMethodManagement->getList($rateRequest);
    
    foreach ($shippingMethods as $shippingMethod) {
        echo $shippingMethod->getMethodCode(); // Output the shipping method code
    }
} catch (Exception $e) {
    echo $e->getMessage(); // Handle any exceptions that occur
}

Make sure to replace the $customerGroupId, 'US', and '12345' with the appropriate values for your specific use case.

By executing this code, you will retrieve the available shipping methods for the specified customer group in Magento 2.
