I have created custom API that excepting 'mixed' type parameter and returning the 'string' as I defined. In interface I define parameter type 'mixed'. As I am trying to pass array as json_encode, it giving me Warning: json_decode() expects parameter 1 to be string, array given in error.` Please let me know how can I pass json array as parameter and return the same.

Here is my code -

etc/webapi.xml

<?xml version="1.0" ?>

<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Webapi:etc/webapi.xsd">

    <route method="POST" url="/V1/managecustomers">

        <service class="NamespaceModulenameApiManageCustomerInterface" method="createUpdate"/>

        <resources>

            <resource ref="anonymous"/>

        </resources>

    </route>

</routes>

etc/di.xml -

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

    <preference for="NamespaceModulenameApiManageCustomerInterface" type="NetzweltCustomerModelManagecustomer"/>

</config>

NamespaceModulenameApiManageCustomerInterface.php :-

namespace NamespaceModulenameApi;

interface ManageCustomerInterface

{

    /**

     * 

     * @param mixed $data

     * @return string

     */

    public function createUpdate($data);

}

NamespaceModulenameModelManagecustomer.php - :

namespace NamespaceModulenameModel;



use NamespaceModulenameApiManageCustomerInterface;



class Managecustomer implements ManageCustomerInterface

{

    /**

     * 

     * @param mixed $data

     * @return string

     */

    public function createUpdate($data) {

        $data = json_decode($data);

        //echo "<pre>"; print_r($data); die;

        return "Hello";



    }

}

If i am passing 'data' parameter as string like -
$customerData = [
'data' => "Abcd"
];

Then its running fine.
But If i am trying to pass 'data' as array like-

$customerData = [

    'data' => [

        "email" => "user@example.com",

        "firstname" => "John",

        "lastname" => "Doe",

        "storeId" => 1,

        "websiteId" => 1,

        "address"=>[

            "street" => "phase-1",

            "phone_no"=> "321654213"

        ]

    ]

];

Then its giving error - Warning: json_decode() expects parameter 1 to be string, array given in error.`

Here is my testapi.php file code -

$ch = curl_init("http://localhost/mage23/index.php/rest/all/V1/managecustomers");

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($customerData));

curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json"));



$result = curl_exec($ch);



echo '<pre>';print_r($result);

Please let me know how can I pass array as parameter in API.
