What are you trying to achieve? Please describe it in detail.

We have created a custom widget where we want to control all of our devices alarms. like get all the alarms, exclate, or event create a alarm on trigger.

We are able to get all the alarms in our widget, but struggling with creating of alarms on threshold trigger.

We know we can create the alarms using smart rule and analytics builder.

But in our case we don’t want to use the out of box application and instead we want to use these apps API and integrate in our custom build widget UI.

So, Can we ask user to give us the device id and threshold value in our widget and UI will call the API which create the EPL workflow in analytics builder?

Thanks

if you are trying to re-build an existing Smart Rule (on threshold alarm) you can just check what API is called under Network tab inside you browser when creating a rule like this in standard UI and simply re-use it
