How to Build a Slack Slash Command App with Rails Discussion
I followed the tutorial and get the following error when I am authenticating the Slack response.
Processing by Slack::CommandsController#create as HTML

If you see 403 Forbidden in ngrok. You have to add ngrok url to whitelist.

Great tutorial!
I'd be interested in learn how to enable a user to publish messages from a Rails App to Slack and the Slack message will be attributed to the user / not a bot.
Hi! great video! I set up my slack app and my first slash command but I am getting an error when typing command in my slack channel: failed with the error "dispatch_failed". The routes seem fine because the request is successful in Postman. My slash command is http://localhost:3000/slack/command. I have tried using ngrok but the error is the same. My routes: post "/slack/command", to: "slack/commands#create". Could you please advise? thanks
