Is there any plan to expand the Workflow API to support other objects besides contacts?
If so, is there a rough timeline as to when this might be supported?
Hey, @MR71 
My recommendation is to subscribe to the developer changelog here HubSpot Developer Changelog It highlights upcoming dev-related updates, betas, and breaking change announcements. We also have our public roadmap pages here What's New in HubSpot's Software Outside of this, I do not have an additional public resource to share.
Best,
Jaycee
I heard it is coming within the year
