The best way to implement a SOAP client is using Symfony Framework. You can follow these easy steps:


Step 1: Install the required dependencies

Make sure you have the required dependencies installed in your Symfony project. You'll need the symfony/http-client and symfony/serializer components. If you don't have them installed, you can use Composer to install them:

$ composer require symfony/http-client symfony/serializer


Step 2: Create a SOAP service class
Create a new class that will act as your SOAP service client. This class will handle the communication with the SOAP server. Here's an example:

namespace App\Service;

use Symfony\Contracts\HttpClient\HttpClientInterface;
use Symfony\Component\Serializer\SerializerInterface;

class SoapService
    private $httpClient;
    private $serializer;
    private $soapEndpoint;

    public function __construct(HttpClientInterface $httpClient, SerializerInterface $serializer)
        $this->httpClient = $httpClient;
        $this->serializer = $serializer;
        $this->soapEndpoint = '';

    public function callSoapOperation($param1, $param2)
        $soapRequest = $this->serializer->serialize(['param1' => $param1, 'param2' => $param2], 'xml');

        $response = $this->httpClient->request('POST', $this->soapEndpoint, [
            'headers' => ['Content-Type' => 'text/xml'],
            'body' => $soapRequest

        if ($response->getStatusCode() === 200) {
            $soapResponse = $response->getContent();
            // Process the SOAP response
            // ...
            return $soapResponse;
        } else {
            throw new \Exception('SOAP request failed');

In this example, the SoapService class uses the Symfony HTTP Client and Serializer components. The constructor injects the HttpClientInterface and SerializerInterface to handle the HTTP communication and serialization of the SOAP requests. The callSoapOperation method sends the SOAP request to the server and handles the response.


Step 3: Use the SOAP service

You can now use the SOAP service in your Symfony controllers or services. Inject the SoapService into your class and call the SOAP operation:

namespace App\Controller;

use App\Service\SoapService;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;

class MyController extends AbstractController
    private $soapService;

    public function __construct(SoapService $soapService)
        $this->soapService = $soapService;

     * @Route("/soap-call", methods={"GET"})
    public function soapCall()
        try {
            $result = $this->soapService->callSoapOperation($param1, $param2);
            // Process the SOAP response
            // ...
            return $this->render('soap_call.html.twig', ['result' => $result]);
        } catch (\Exception $e) {
            // Handle SOAP request error
            // ...

In this example, the SoapService is injected into the MyController constructor. The soapCall method calls the SOAP operation by invoking the callSoapOperation method of the SoapService. You can handle the SOAP response and errors according to your application's logic.


Customize the SOAP service class and the controller according to your specific SOAP API requirements.
