1. Create a GraphQL Schema file schema.graphqls in your module directory.

Here is the code.

type Mutation {
    createShipment(input: ShipmentInput!): ShipmentOutput
}

input ShipmentInput {
    order_id: Int!
    items: [ShipmentItemInput]
}

input ShipmentItemInput {
    order_item_id: Int!
    qty: Float!
}

type ShipmentOutput {
    shipment: Shipment
}

type Shipment {
    increment_id: String
    trackings: [Tracking]
}

type Tracking {
    track_number: String
    carrier_code: String
}

Here's an example of how you can create a resolver class that handles the createShipment mutation in Magento 2:

<?php
namespace Vendor\Module\Model\Resolver;

use Magento\Framework\GraphQl\Config\Element\Field;
use Magento\Framework\GraphQl\Exception\GraphQlInputException;
use Magento\Framework\GraphQl\Query\ResolverInterface;
use Magento\Framework\GraphQl\Schema\Type\ResolveInfo;

class CreateShipmentResolver implements ResolverInterface
{
    /**
     * @var \Magento\Sales\Api\ShipmentRepositoryInterface
     */
    private $shipmentRepository;

    /**
     * @var \Magento\Sales\Api\OrderRepositoryInterface
     */
    private $orderRepository;

    public function __construct(
        \Magento\Sales\Api\ShipmentRepositoryInterface $shipmentRepository,
        \Magento\Sales\Api\OrderRepositoryInterface $orderRepository
    )
    {
        $this->shipmentRepository = $shipmentRepository;
        $this->orderRepository = $orderRepository;
    }

    public function resolve(Field $field, $context, ResolveInfo $info, array $value = null, array $args = null)
    {
        $shipmentDatas = [];
        $order = $this->orderRepository->get($args['input']['order_id']);
        if (!$order->canShip()) {
            throw new GraphQlInputException(__('Order cannot be shipped.'));
        }

        $items = $args['input']['items'];
        $data = [];
        foreach ($items as $item) {
            $data[$item['order_item_id']] = $item['qty'];
        }

        $shipment = $this->shipmentRepository->create(
            $order,
            $data,
            __('Shipment Created from GraphQL')
        );

        $this->shipmentRepository->save($shipment);

        $increment_id = $shipment->getIncrementId();
        $trackings = $shipment->getAllTracks();

        $trackingData = array();
        foreach ($trackings as $tracking) {
            $trackingData[] = [
                'track_number' => $tracking->getNumber(),
                'carrier_code' => $tracking->getCarrierCode()
            ];
        }
        
        $shipmentDatas = [
            'increment_id' => $increment_id,
            'trackings' => $trackingData
        ];

        return $shipmentDatas;
    }
}

Let me know if any query.

THANKS.
