I want to build a Slack bot that can answer support queries. I've designed the conversation in Watson Conversation, but now I want to deploy it to Slack channels.
Ideally I don't want to have to develop and host an application to broker messages between the two systems.
Is there any platform or solution that I can use?
There are two possible solutions that I can think of.
Watson Conversation offers some basic integration with Slack through an application you can deploy yourself in a container. I believe they have a repo in their github (https://github.com/IBM/slack-watson-bot). You'll have to host this somewhere, though Bluemix offers some basic free hosting for a limited time. There are plenty of tutorials out there for spinning up containers in Bluemix.
An alternative solution (disclosure - this is my company) that wouldn't require hosting or development would be to use Bothaus (https://bothaus.io). Bothaus lets you configure integration between Slack and Watson Conversation without hosting or coding anything.
