Slack bot: Car Lookup

Slackbot to scan images for licence plates and report the known car details. The car owners are fetched from a csv-file on a fileshare.

Hosting

• Create an app in api.slack.com
  • configure /car slack commmand
  • configure event-api on file_created / file_shared events in channel-scope
• Host as a docker container in the cloud, or use nGrok while testing.
  • Pass environment variables from Slack and/or opendata.rdw.nl
    • ACTIVE_TOKEN OAuth Bot User OAuth Access Token (xoxb-***)
      • CLIENT_ID + CLIENT_SECRET and perform OAuth by '(Re)install app' in Slack API.
    • RWD_APPTOKEN (optional) the opendata.rdw.nl api-token

Components:

• Open data: RWD gekentekende voertuigen
• Github project: Open Automated LicencePlate Recogniser

Testing locally

Only if Flask is running in debug mode:

• http://localhost:5000/test?kenteken=28-ZTP-6
• http://localhost:5000/test?file=someimage.jpg

TODO's:

• Make the bot Workspace independend: Its now for a single Workspace (Xebia) using one fileshare with a single csv-file.
• Make API calls in parallel to reduce total time for a request. (A slack command must answer in 3 sec.)
• Security:
  • Limit the incoming traffic from Slack or validate event hashes.
  • Add an TSL-certificate using letsencrypt
  • Pin Slack SSL certification.
