Podemos enviar imágenes, documentos y medios convirtiendo los archivos a base64.
convertir archivo a Base64 usando ultramsg UI
puede convertir cualquier archivo utilizando File to Base64 Tools desde el menú Ultramsg después de iniciar sesión en su cuenta en Ultramsg.
paso 1: convertir la imagen a Base64:
paso 2: Enviar imágenes de WhatsApp como Base64:
Simplemente podemos poner Base64 en lugar del enlace HTTP como se muestra en la siguiente imagen:
Ejemplo para enviar imágenes de WhatsApp como base64 usando PHP
$instance='instance1150';
$token='Token_123456';
$to='14155552671';
///////////
$path="1.jpg";
$data = file_get_contents($path);
// you can convert File to Base64 using ultramsg UI
// https://user.ultramsg.com/app/base64/base64.php
//Encodes data base64
$img_base64 = base64_encode($data);
//urlencode — URL-encodes string
$img_base64 =urlencode($img_base64 );
////////////
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://api.ultramsg.com/$instance/messages/image",

$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {

}
