JSM - Create SLA Programmatically

[Marina Ferraz McCashin]

Hi folks

I have been working through this tutorial here: https://developer.atlassian.com/server/jira/platform/creating-automation-rule-components/ but I am now at the next point where I want to create my own SLA. 

However, for all my research and poking around I don't believe this is possible. 

Can anyone confirm if I can programmatically create/install an SLA for projects in an addon? 

Is it possible to create an SLA using the REST API? 

Any feedback is appreciated. 

Thanks in advance

Marina.
