Basics
A minimal webhook handler that receives HTTP GET requests and responds with a personalized greeting. Great for learning how HTTP Endpoint blocks produce request events and expect response events back.

You can see that the **HTTP Endpoint** block produces events on its `requests` output, and expects a response to arrive at its input.
 To test this Flow, first click on the **Sample Endpoint** block, then click on the copy button next to the **Path** field. You can navigate to the copied URL using your browser, or curl it.
 Once you do that and get a response, you will also see events appear on the canvas next to various outputs. Click on an output to see the events it produced!
 You can **re-emit** those events, in order to replay parts of your flow - great for debugging, or just building up your flow piece by piece!
