GroupMe bot/Steam API integration
Currently all configuration is managed by environment variables. These are the important keys; details about getting the values are below.
export STEAM_KEY=1234ABCD...
export STEAM_ENDPOINT=http://api.steampowered.com
export GROUPME_BOT_ID=1234abcd...
export GROUPME_ENDPOINT=https://api.groupme.com/v3/bots/post
export STEAM_IDS=1234,2345,3456,...
Personally I use direnv to manage environments--the above is a sample .envrc file placed in the project root.
Register and get your own API key from Steam.
Comma-delimited list of SteamIDs for the bot to follow (e.g., getting online/offline status).
You can get your own SteamID by logging in to Steam in a browser, then going to your profile. The link should look like:
https://steamcommunity.com/profiles/12345678901234567/
If your profile is public, http://localhost:4567/12345678901234567 or http://doto.lidaka.us/12345678901234567 should show your friend list. From here you can readily get your friends' SteamIDs.
Sign up for an access token on GroupMe, then either read the tutorial or directly create your bot. Also I've already created a test bot ID and GroupMe channel--please email me for details if you don't want to create your own just yet.
When creating your bot, the host for your callback URL should be publicly-accessible, with path /bot/callback; e.g., http://example.com/bot/callback.
bundle install
bundle exec ruby lib/dototime/app.rb
Visit http://localhost:4567 for the web site.
To test the callback locally, simulate posted messages (more fields documented on GroupMe's tutorial):
curl -X POST -d '{"text":"!help"}' -H 'Content-Type: application/json' http://localhost:4567/bot/callback
