Following is my partial code but for some reason image is sending just fine but when I try to download the receiving image it just don't work at all and doing nothing. I expected for it to get downloaded somewhere in my directory and nothing is happening down there. Please let me know how to save the file into the directory?

require 'vendor/autoload.php';

use Netflie\WhatsAppCloudApi\Message\Media\LinkID;
use Netflie\WhatsAppCloudApi\Message\Media\MediaObjectID;

$waimgId = $webhookData["entry"][0]["changes"][0]["value"]["messages"][0]["image"]["id"];
$whatsapp_cloud_api->sendTextMessage($senderNumber,  $waimgId);
$media_id = new MediaObjectID($waimgId);
$whatsapp_cloud_api->downloadMedia($media_id);

Following is the code for Downloading any type of media received by whatsapp and then saving it into the directory:

// Get the message type
$messageType = $webhookData['entry'][0]['changes'][0]['value']['messages'][0]['type'];

//Get the id of the media received 
$waimgId = $webhookData["entry"][0]["changes"][0]["value"]["messages"][0][$messageType]["id"];
       
//For testing purpose send the id in text messageon whatsapp
$response = $whatsapp_cloud_api->sendTextMessage($senderNumber,  $waimgId);

//Get the Media
$response = $whatsapp_cloud_api->downloadMedia($waimgId);
      
// Create a reflection object of the Response class
$reflectionObj = new ReflectionObject($response);

// Get the value of "Content-Type" header
$headers = $reflectionObj->getProperty('headers');
$headers->setAccessible(true);
$contentType = $headers->getValue($response)['Content-Type'][0]; // Extract the content type from headers

// Get the file extension from the content type
$extension = explode('/', $contentType)[1];

// Generate a unique ID of 5 characters
$uniqid = substr(str_shuffle(str_repeat('0123456789abcdefghijklmnopqrstuvwxyz', 5)), 0, 5);

// Construct the file name with the unique ID and extension
$wafilename = $messageType.'-'.$uniqid.'.'.$extension;

// Get the value of "body" property which contains main media file
$body = $reflectionObj->getProperty('body');
$body->setAccessible(true);
$bodyContent = $body->getValue($response);

// Save the body content to a file with the extension of the content type
file_put_contents('media-received/'.$wafilename, $bodyContent);

You just have to save the content body of the response:

file_put_contents('file-name', $response->getBody());
