Github is the place to be for open source and collaboration! But we wouldn't want to invite everyone by hand in the GitHub organization of DO!Hack. So for the most part our Github bot handles the things that are possible with the Github API. Only some team configuration needs to be done by yourself. So try it out and give us feedback, if any problems occure - our mentors are there to help you! ;)

  1. Before using the Bot:
    1. Every team member needs an account at Github. If you don't have one, you can register yourself at:
    2. Don't forget to activate your account.
  2. Using the bot
    1. Only your team captain visits and follows the on screen instructions.
      Be aware: Github names are case-sensitive, so double check the spelling.
  3. After using the bot
    1. All team members should have an invite to join the GitHub organization of DO!Hack. You can check your invites via or email
    2. All team members should also have an invite to join your created repository. You can check your invites via{myRepoName}/invitations or email
    3. Additional Steps for your team captain:
      1. Create a team on the GitHub organization of DO!Hack you just joined:
        (Button "new team")
      2. Invite your teammates to the team:{myTeamName}/members
        (Button "Add a member")
      3. Configure your desired permission level of the team on your repository:{myRepoName}/settings/collaboration
        (Button "Add a team" and choose your team and on the right a permission level - we recommend the "write" level for newbies and higher permissions ("maintainer" or "admin") for advanced users))
  4. Nice! Now you have: - Your own team and repository. Welcome in our Github organization! Happy Coding!

Together with the city of Dortmund we provide you with some APIs to get data for your projects. These interfaces can provide different sets of data, for example JSON, XML or CSV. If you have questions to one of the endpoints feel free to ask one of our mentors on the event.

If you want to work with the CIRC API please contact us and we'll provide you with the credentials. The API produces links which are not working at the moment. Please use URLs like '' instead of the generated URLs like ''. If there are any problems please contact a mentor.
