Adobe Drive client libraries provide check-in option in the illustrator.
Inside illustrator can we add an event listener to the check-in option?
Or is it possible to trigger a check-in using a custom illustrator plug-in?
I do not find any documentaion about the Adobe drive client libraries.
From my knowledge, inside Illustrator, you can't add an event listener to the the check-in option, but I am not sure about that, you can ask help from Illustrator forum.
Regarding how to trigger a check-in using a custom Illustrator plug-in, currently, you can't do it, one option is asking Illustrator to add this functionality in Illustrator SDK. another option is, Adobe Drive adds a helper library, in the custom Illustrator plug-in, you can invoke check-in operation from this library, however, there is a drawback of this option, this will break the check-in logic of Illustrator, how to notify Illustrator and refresh document status is a problem.
