Sending 2-way-SMS is done the same way as sending Bulk SMS message. Refer to the send Bulk SMS section HERE for more details.
We will asynchronously send a notification to your callback URL whenever a message is received by any of your registered shortcodes.

Setting a username & password on callback (Optional Authentication)

It is possible to predefine an Auth Key for your message callbacks. This value will then be included as parameters in the body to allow your system to authenticate that the request is indeed from Sozuri.
