Which automation is designed to run when a user interacts with buttons or links?

The correct answer is autolaunched flow. This type of flow is specifically designed to be invoked programmatically, which includes being triggered by user interactions such as clicking buttons or links in the Salesforce interface. Autolaunched flows can be run from various points within Salesforce, including Lightning components or through Quick Actions, making them highly versatile for situations where user engagement prompts a need to automate a series of tasks or calculations.

In contrast, screen flows are designed for direct user interaction and involve user input through screens, which makes them unsuitable for scenarios where they are triggered solely by button clicks without additional user feedback. Record-triggered flows activate automatically based on specific changes to record data, rather than user actions directly. Lastly, approval processes are used for handling approval requests and workflows based on record changes, which do not fit the description of being triggered simply by a button click. Each of these other options serves different purposes within Salesforce automation, highlighting the unique capabilities of autolaunched flows to respond to user interactions effectively.
