Bis correct — theArgumentinput method is used when you want a field in an activity (such as a tool, API call, or process input) to dynamically receive a valueat runtime, passed viaagent input argumentsdefined earlier in the flow.
This setup is critical for:
Contextual automation: e.g., if the user or upstream system provides a value like Customer_ID, that same value can be used in downstream tools.
Reusability: One workflow can behave differently based on argument values passed at runtime (e.g., from Orchestrator triggers, API calls, or user prompts).
Maintainability: Centralizing inputs allows for consistent data mapping and easier debugging.
Here’s how it works:
You define aninput argumentin the agent's Data Manager (e.g., {{CUSTOMER_EMAIL}})
In the activity, you set the input method toArgument, and reference the same name
At runtime, UiPath automatically maps the values based on the execution context
Option A is describing theStaticinput method.
C refers to thePromptmethod, where the LLM infers values.
D is incorrect — that's thePrompt for user input, not theArgumentflow.
In summary, choosingArgumentenables your agent to behavedynamically and intelligently, using external or user-provided data without hardcoding.
