MMS API attachment endcoding 

Recommendations on how to base64 encode attachments for sending via MMS API

MMS Attachments are required to be base64 encoded.

Below are some examples of how to encode an attachment in different programming languages.

PHP

$path = 'myfolder/myimage.png';
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);

Java

private static String encodeFileToBase64Binary(String fileName) throws IOException {
   File file = new File(fileName);
   byte[] encoded = Base64.encodeBase64(FileUtils.readFileToByteArray(file));
   return new String(encoded, StandardCharsets.US_ASCII);
}
