Capability of Plugins to handle activity and inventory related events

Hi Team,

We are looking for the capability for plugins to handle following scenarios. Please let us know what all feasible and not feasible .

1 - When any of these events occur, technician start the travel / start the activity / change activity statuses / end the activity / activity not started then execute the plugin and call an external API

2 - A new inventory get assigned to the resource then execute the plugin and call an external API

3- If these are feasible , would the integration work in offline scenario?
