Steps on how to create your Slack App can be found here
After it's all set up you can add the bot to a channel in your slack workspace.
To use it just type any symbol prefixed by the $ sign and the bot will reply with the stock information. (i.e $TSLA, $SBUX)
Like this:
It supports pre/post market notifications as well!
Export the token and signing keys as environment variables:
export SLACK_BOT_TOKEN='YOUR_BOT_TOKEN_HERE'
export SLACK_SIGNING_SECRET='YOUR_SIGNING_KEY_HERE'
Configure ngrok (you could use other service if you prefer) to create a public URL that tunnels the requests to your machine. Steps to configure ngrok can be found here
Make sure you run ngrok specifying the same port as defined in bot.py
Run the bot:
$ python3 bot.py
* Serving Flask app "bot" (lazy loading)
* Environment: production
WARNING: This is a development server. Do not use it in a production deployment.
Use a production WSGI server instead.
* Debug mode: off
* Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
After it's all up and running you need to go to Slack Apps -> Features -> Event Subscriptions and enable events as well as adding the ngrok url and include message.channels in the list Subscribe to bot events
If you don't want to host the bot locally you can use the free tier of Heroku to host it. This repo includes the requirements.txt and Procfile needed for Heroku to identify this project as Python app and run it after building it.
More details on how to setup Heroku, push the code, etc can be found here
Don't forget to configure the environment variables:
If you have heroku cli, configure environment variables like this:
heroku config:set SLACK_BOT_TOKEN="YOUR_BOT_TOKEN_HERE"
heroku config:set SLACK_SIGNING_SECRET="YOUR_SIGNING_KEY_HERE"
If you don't want to use the cli they can be configured on the app Dashboard -> Settings -> Config Vars
After it's all up and running you need to go to Slack Apps -> Features -> Event Subscriptions and enable events as well as adding the heroku url and include message.channels in the list Subscribe to bot events
