Zappa creates a Lambda function containing your Flask app and sets up a wildcard API Gateway route to proxy requests from Slack to the app. Then, just like before, navigate back to your app’s “Slash Commands” section in your browser and edit the configuration of the /hello-there command, replacing the ngrok forwarding URL with the API Gateway URL. To be more faithful to the scene from Revenge of the Sith, you now want your /hello-there command to respond with “General Kenobi!”, followed 5 seconds later by “You are a bold one.” Your command’s backend has to do more work now: receive a POST request, verify that the request was issued by Slack, schedule a task that will issue the second message 5 seconds in the future, and respond immediately with the first message.
