A simple Sinatra app to proxy Airbrake webhooks to Cisco Spark Rooms

README.md

Setup

brew install jq # or apt-get install jq (only needed for testing)          
rvm install ruby-2.4.1
rvm gemset create spark
rvm gemset use spark
gem install cisco_spark --no-document
gem install sinatra --no-document

Testing

Open two terminal sessions. In the first run ruby app.rb -b 0.0.0.0

In the second POST webhook.json to the Sinatra endpoint

curl -s -XPOST -H "Content-Type: application/json" \
  -d @webhook.json \
  "http://localhost:4567/event" | jq

app.rb

#!/usr/bin/env ruby

require 'cisco_spark'
require 'sinatra'

CiscoSpark.configure do |config|
  # https://developer.ciscospark.com/getting-started.html#authentication
  config.api_key = 'YOUR_API_KEY_GOES_HERE'
end

# Room ID is a UUID. Either retrieve via the API or https://web.ciscospark.com/rooms/uuid-would-be-here
room = CiscoSpark::Room.fetch('YOUR-UUID-GOES-HERE')

post '/event' do
  status 201

  request.body.rewind
  request_payload = JSON.parse(request.body.read)

  # Expects https://airbrake.io/docs/integrations/webhooks/
  message = CiscoSpark::Message.new(text: request_payload['airbrake_error_url'])
  room.send_message(message)
end
