Hello. I am a theme developer and wish to bundle Toolset functionality with my theme. Does the WP Toolset Developer API still exist? If so, how do I request a developer API key? Thank you
That was an experiment that didn't work, and the expectation is that you create websites for clients include Toolset plugins and functionality which you manage, there isn't a model whereby you distribute Toolset plugins with a theme that you sell on to others.
