Sms id send to gateway URL

I use version 1.4 of PlaySMS. I need to send the message id to the gateway in the URL. How do I do? I’ve tried a few things, but nothing solved.{GENERIC_API_USERNAME}&password={GENERIC_API_PASSWORD}&sender={GENERIC_SENDER}&recipients={GENERIC_TO}&message={GENERIC_MESSAGE}&msgid={GENERIC_IDMSG}

By default, seems doensn´t have. But you always can modify generic plugin to send smslog_id, for example.

I had seen that it has how to add a few instants. Thanks for the answer. I will do the modification and I will post here to help others. Well that Anton could already leave it fixed.
