$payload = $single_message->getPayload();
$body = $payload->getBody();
$FOUND_BODY = $this->decodeBody($body['data']);

You'll probably want to use the SENT system label (instead of the Label_56 one) in your curl_init() call:
SENT
Applied automatically to messages that are sent with drafts.send
or messages.send, inserted with messages.insert and the
user's email in the From header, or sent by the user through the
web interface.
