Branch Action

Branch Action is a flow control action that enables conditional workflow branching based on specified criteria or expressions. It evaluates a given condition and, depending on the result (true or false), directs the automation flow to different subsequent actions. This allows for dynamic decision-making within workflow automations, supporting complex logic and adaptive process execution. Typical use cases include debugging, processing different data types, or responding to varying user inputs within an automated workflow.

Appearance

In Talos, Branch Action appears as a diamond-shaped node, symbolizing a decision point. It visually distinguishes itself from other actions by indicating multiple possible outgoing paths, each corresponding to a different evaluation result (e.g., true/false).
