Solarwinds with SMS API for Alert Notification

Hi,

There is a requirement to integrate SMS API for sending the alert SMS to users. For integrating SMS API service for this purpose need help on below doubts- 

1> What changes I need to do in my Solarwinds settings? 

2> What all details I need to implement this? 

3> How can we leverage this functionality at it's best with SolarWinds? 

4> Any article or documentation on this? (I tried to search but could not find a good one)

Thanks!
