Overview
A workflow is typically composed of several connected operational steps. Each node represents one of these steps and serves as a basic logical unit in the process. Just like in a programming language, different types of nodes represent different instructions, which determine the node's behavior. When the workflow runs, the system enters each node sequentially and executes its instructions.
Note
A workflow's trigger is not a node. It is only displayed as an entry point in the flowchart, but it is a different concept from a node. For details, please refer to the Triggers content.
From a functional perspective, the currently implemented nodes can be divided into several major categories (28 types of nodes in total):
