It would be great to have the ability to build flows based on activity/events in VSTS/VSO as a means of monitoring and engaging with engineering workflows.
Why isn't this here already? You've done GitHub, Slack, ... I tried doing it myself with the API, but could not get the authentication to work and there is no Swagger on VSTS to make it easy.
You can see a number of templates for VSTS here: https://flow.microsoft.com/en-us/services/shared_visualstudioteamservices/visual-studio-team-service...
