Prerequisites and setup

Slack app setup

Note that you will need your application to be exposed in order to setup correctly the requested callback URLs and so on

Setup bot config file

The config file is handled here

slack:
  appURL:               # Base URL of the bot
  signingSecret:        # Slack signing secret (https://api.slack.com/apps/${APP_ID}/general)
  clientID:             # Slack client ID (https://api.slack.com/apps/${APP_ID}/general)
  clientSecret:         # Slack client secret (https://api.slack.com/apps/${APP_ID}/general)
  callbackURL:          # Callback URL (https://${APP_URL}/auth/slack/callback)
  token:                # Slack verification token (https://api.slack.com/apps/${APP_ID}/general)
server:
  port:                 # Bot webserver port
database:
  name:                 # Database name
  host:                 # Database host/address
  username:             # Database user
  password:             # Database password
core:
  cryptoKey:            # Message hashing string
  expirationTime:       # Expiration time of message in database (in seconds)

Build and run the app

Build requires GNU Make and golang (tested using go 1.18.4)
The application requires also a Postgres database.

  • Build the app make build
  • Run the app ./secretmessage

For Slack to be able to send data thru application callbacks, the application must be publicly hosted. It can be tested using tools such as ngrok for TCP tunneling.

Send a secret message

Just type /secret and your message, such as /secret I'm scared of heights
