What is the difference between an action and a trigger in MS-Flow?
Answer»
Action:CHANGES guided by a User are referred to as actions. For example, you can utilise an action to do SQL Database operations such as lookup, update, and remove data. All actions will have direct mappings to SWAGGER operations.
Trigger:SEVERAL connectors have triggers that can be used to notify your app when certain events occur. Let's look at an FTP CONNECTOR with the OnUpdatedFile trigger as an example. You can create a Logic App or a flow that listens for this trigger and takes action whenever it occurs.
Polling Trigger: These triggers can check for new data by calling your service at a specific interval. When fresh data becomes available, your workflow instance will be restarted with the new data as input.
Push Trigger: These triggers can listen for data on an endpoint, which implies they'll wait for something to happen. The event triggers a fresh execution of your workflow instance whenever it occurs.
