I want to upload the media via Whatsapp cloud API in order to send the media to WhatsApp, I have followed the link below, but having the stated issue.
https://developers.facebook.com/docs/whatsapp/cloud-api/reference/media#get-media-id
Array ( [error] => Array ( [message] => (#100) The parameter messaging_product is required. [type] => OAuthException [code] => 100 [fbtrace_id] => AQPftb9Bf343375gQ_QytxNen ) ) 400
My Code is
// @1640191015925.jpg on my root folder
$post = [
'file' => '@1640191015925.jpg;type=image/jpeg',
'messaging_product' => 'whatsapp'
];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/v13.0/Phone-Number-ID/media');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$headers = array();
$YOUR_WHATSAPP_ACCESS_TOKEN = '+++++++';
$headers[] = "Authorization: Bearer $YOUR_WHATSAPP_ACCESS_TOKEN";
$headers[] = "Content-Type: image/jpeg";
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = json_decode(curl_exec($ch), true);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
//$MEDIA_OBJECT_ID = $result['media'][0]['id']; //MEDIA OBJECT ID
print_r($result);
print_r($httpcode);
?> ```
I had the same issue, after some digging around I wrote this function to upload a file and return the id.
function waFileUploader($token, $file, $senderid){
$mime = mime_content_type($file);
$info = pathinfo($file);
$name = $info['basename'];
$curlfile = new CURLFile($file, $mime, $name);
$filedata = array("messaging_product"=>"whatsapp", "file" => $curlfile);
$url = 'https://graph.facebook.com/v13.0/' . $senderid . '/media';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER,array("Authorization: Bearer $token", "Content-Type: multipart/form-data"));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $filedata);
$r = curl_exec($ch);
curl_close($ch);
$id = json_decode($r, true);
return $id["id"];
}
