1) One way messages ,2) Two way messages, 3) Both ways messages . Here one ways only allow to send message to customer but two way also allow to receive reply messages
from customers .Depending upon SMS Gateway provider , API may quite from each other . Generally we have to pass some parameters to there callback url of API to send messages .
