Action

As explained in Microsoft Azure in Action

An action is an executable step in a workflow that performs an operation after the workflow starts.

An action is an executable step in a workflow. In an Azure Logic App, it runs after the trigger starts the workflow, manipulates data, and delivers the useful business outcome. section 8.6 section 2.5

Actions can be chained so that one step supplies data to the next:

  • Choose an operation such as Get Blob Content (V2), then provide its storage connection, blob path, and content-type setting. section 8.3.3
  • Use the retrieved blob data in a later action, such as Post a Tweet. section 8.3.3
  • Authenticate the target service and fill its required parameters, such as tweet text and media. section 8.3.3
  • Build workflows with one action or many; Logic Apps can connect disparate third-party services without writing orchestration code. section 8.6

Blob upload to social post

A blob insertion triggers a Logic App. A Get Blob Content (V2) action retrieves the image, and a Post a Tweet action publishes it using the image as media. The content dialog supplies values from the earlier step—small conveyor belt, useful cargo. section 8.3.3

How Microsoft Azure in Action covers it

How deep it goes
Explains chaining, parameters, dynamic content, and authentication, but stops short of implementation internals.
Examples
Demonstrates retrieving blob content and posting an image-containing tweet through sequential Logic App actions.
What it assumes
Assumes a Logic App workflow and trigger, while demonstrating service connections, authentication, and parameter selection.
What you can do after
Apply it via Azure Logic Apps to construct multi-step workflows that pass data between connected services.
How it connects
Connects actions with triggers, Logic Apps, Blob Storage, dynamic content, service connections, and authentication.
