Today we are going to talk about how to get params data in Magento 2 api.

You can use this class for this MagentoFrameworkWebapiRestRequest

And below code.

<?php
namespace MagemonkyesParamsModel;
use MagentoFrameworkWebapiRestRequest;
class GetpostParams
{
    public function __construct(
        Request $requestparam
    ) {
        $this->requestparam = $requestparam;
    }

    public function getParampostgetValue()
    {
        $filter = $this->requestparam->getParam('name');
    }
}
