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"];
}
