Chatbot Workshop @ DecompileD 2018

A lot of companies are investing in chat bots. In this workshop, we will develop a fully functional chat bot from scratch with support for formatted messages, photos, documents, locations, buttons, custom keyboards and more. No slides, just code – and a lot of fun…

Do you understand the user interface of every website and every application? I don’t! Do you understand how to use a chat application like WhatsApp, Telegram, Threema, Signal, Facebook Messenger, etc? I do! If everyone knows how to chat, what if we provide our business services using a chat bot as a user interface? Let’s have some fun and create a chat bot live on stage as an introduction to this very interesting topic! In this workshop we will start a new empty project and write a complete and working chat bot from scratch for Telegram. Our bot will receive messages from other Telegram users, analyze them and send an appropriate answer. The messages can be formatted and contain photos, documents and locations. We will use custom and inline keyboards, callback buttons and much more. Be prepared: After this workshop you will have an own working chat bot on your notebook and there will be nothing to stop you from writing more and amazing chat bots!

To fully understand this workshop the attendees should have basic knowledge of Java.

    Code Warriors wanted!
    About you
    ● You are frighteningly awesome at what you do.
    ● You can perform quick and deadly tactical
    strikes, as well as feats of epic badassery.
    Sometimes both at the same time.
    ● You would rather refactor existing, mostly
    working, ugly code instead of rewriting it from
    scratch. OK nobody would really rather do that,
    but you know it's the right and honorable thing
    to do most of the time.
    ● You know where your towel is.
