What is the main purpose of a Webhook URL?

• A. To allow another application to run a workspace programmatically.
• B. To send a workspace to a user and allow them to configure parameters without logging into FME Server.
• C. Webhook URLs provide a way for users with login credentials to FME Server to run workspaces easily.
• D. Webhooks URLs can be used to run a workspace without using engine time.

Answer: (A)

A webhook URL is an endpoint that external systems can call to start a workspace on FME Server automatically. The main idea is to enable programmatic execution: when something happens in another app, it can trigger a run in FME Server without someone logging into the server UI. This makes it easy to integrate FME workspaces into automated workflows, dashboards, or CI/CD pipelines by sending parameters as needed through the webhook call. The other options describe scenarios involving delivering a workspace to a user, requiring login, or bypassing engine time, which aren’t how webhooks function. In reality, triggering a workspace via a webhook still uses engine time to run the workflow.
