To download an image received from the webhook, first, I retrieve the URL with the call to the media endpoint, I execute a curl call to

https://graph.facebook.com/v14.0/xxxxxxxxxxxxxx 

where xxxxxxxxxxxxxx is the media id.

The code I use to do that is:

$token = 'sdfsfsdfd'; $curl = curl_init(); curl_setopt_array($curl, array(   CURLOPT_URL => 'https://graph.facebook.com/v14.0/xxxxx',   CURLOPT_RETURNTRANSFER => true,   CURLOPT_ENCODING => '',   CURLOPT_MAXREDIRS => 10,   CURLOPT_TIMEOUT => 0,   CURLOPT_FOLLOWLOCATION => true,   CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,   CURLOPT_CUSTOMREQUEST => 'GET',   CURLOPT_HTTPHEADER => array(     'Authorization: Bearer '.$token,     'Content-Type: application/json'   ), ));   $response = curl_exec($curl); curl_close($curl); echo $response."<hr>"; $dati = json_decode($response); 

and the $response is:

(     [url] => https://lookaside.fbsbx.com/whatsapp_business/attachments/?mid=790316572396xxx&ext=1659596318&hash=ATuHn61BbJOBYzugyRcP6O6UnyY2NSVh3Bb8v12OS3OCzQ     [mime_type] => image/jpeg     [sha256] => 1cf4a54f0d86c6603d10ad2e9836bc5a98edfabab4b5b8120822be59cbdcxxx0     [file_size] => 253685     [id] => xxxxx     [messaging_product] => whatsapp ) 

After this, I make a new curl call to the obtained URL

$curl = curl_init(); curl_setopt_array($curl, array(   CURLOPT_URL => $dati->url,   CURLOPT_RETURNTRANSFER => true,   CURLOPT_ENCODING => '',   CURLOPT_MAXREDIRS => 10,   CURLOPT_TIMEOUT => 0,   CURLOPT_FOLLOWLOCATION => true,   CURLOPT_USERAGENT => 'Mozilla/5.0 (Macintosh; Intel Mac OS X 12_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.0.0 Safari/537.36',   CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,   CURLOPT_CUSTOMREQUEST => 'GET',   CURLOPT_HTTPHEADER => array(     'Authorization: Bearer '.$token        ), )); $response = curl_exec($curl); if(curl_errno($curl)){     throw new Exception(curl_error($curl)); } $getstatusCode = curl_getinfo($curl, CURLINFO_HTTP_CODE); if($getstatusCode == 200){          echo 'Downloaded!<hr>';              echo $response;      } else{          echo "Status Code: " . $getstatusCode;      } 

But the $response obtained is the "something went wrong".

I would have expected a binary blob instead.

Where did I go wrong?

Please note, this issue is in Whatsapp Cloud API not the business API.

    I had the issue of getting an error with browser and changed the User-Agent within the header to a postman like one: User-Agent: PostmanRuntime/7.34.0 And it worked Just for future readers (or me if I forget it)

      That's such an odd fix, but thanks, this helped me! I wonder why they still require a user-agent; we're already providing a Bearer token.
