Which Trigger Type would you choose to start an automation in response to an external web service call?

• A. Webhook
• B. Manual Trigger
• C. Schedule
• D. Directory Watch

Answer: (A)

When you want an automation to start because an external web service calls in, you need a mechanism that exposes an HTTP endpoint and triggers the workflow from that call. A webhook trigger provides exactly that: it gives you a URL that an external system can call (often with a POST payload), and that event starts the automation flow. This makes it the natural fit for event-driven integration with web services. The other options don’t match this scenario. A manual trigger requires someone to start it, not an external service. A schedule trigger runs at predefined times, independent of web requests. A directory watch starts when a file appears or changes in a folder, not in response to an HTTP call from a web service.
