Creating a helpdesk ticket using a Slash Command and a ~~Dialog~~ Modal

Use a slash command and a dialog to create a helpdesk ticket in a 3rd-party system. Once it has been created, send a message to the user with information about their ticket.

Setup

Create a Slack app

1. Create an app at https://api.slack.com/apps
2. Add a Slash command (See Add a Slash Command section below)
3. Enable Interactive components (See Enable Interactive Components below)
4. Navigate to the OAuth & Permissions page and select the following bot token scopes:
   • commands
   • chat:write
   • users:read
   • users:read.email
   • im:write
5. Click 'Save Changes' and install the app (You should get an OAuth access token after the installation)

Add a Slash Command

1. Go back to the app settings and click on Slash Commands.
2. Click the 'Create New Command' button and fill in the following:
   • Command: /helpdesk
   • Request URL: Your server or Glitch URL + /command
   • Short description: Create a helpdesk ticket
   • Usage hint: [the problem you're having]

If you did "Remix" on Glitch, it auto-generate a new URL with two random words, so your Request URL should be like: https://fancy-feast.glitch.me/command.

Enable Interactive Components

1. Go back to the app settings and click on Interactive Components.
2. Set the Request URL to your server or Glitch URL + /interactive.
3. Save the change.

Set Your Credentials

1. Set the following environment variables to .env (see .env.sample):
   • SLACK_ACCESS_TOKEN: Your bot token, xoxb- (available on the OAuth & Permissions once you install the app)
   • SLACK_SIGNING_SECRET: Your app's Signing Secret (available on the Basic Information page)
2. If you're running the app locally, run the app (npm start). Or if you're using Glitch, it automatically starts the app.

Run the app

1. Get the code
   • Clone this repo and run npm install
2. Set the following environment variables to .env (see .env.sample):
   • SLACK_ACCESS_TOKEN: Your bot token, xoxb- (available on the OAuth & Permissions once you install the app)
   • SLACK_SIGNING_SECRET: Your app's Signing Secret (available on the Basic Information page)
3. If you're running the app locally, run the app (npm start).

If you want to run it locally, I recommend creating a localhost tunnel with ngrok!
