I’d like to know if there is any way to make web requests as an action and use web request as trigguer in rule engine.
Outbound web requests (REST) are on the short list for the Rule Engine. For using a web request as a trigger, are you referring to a Rule exposing a webhook which you could trigger via a REST call?
Are the outbound endpoints that you want to hit public? (Eg. Not on your local network)
Yes a kind of webhooks service like in ifttt app…
