How can one set the edgeColor property for an attachment? Seems like there is not PUT for the nested card resource, only GET and DELETE . And it’s not a property of the attachments endpoint either (unless I’m overlooking it in the docs). However, I’ve seen some libraries that allow it, so it’s got to be possible, right?
Can you point to some of the libraries that allow it?
A brief look at the API endpoints and I’m not seeing an obvious way to update it. It looks like it is derived from an attachment object that has been generated by the attachment preview service (which is responsible for generating the smaller preview images used on the card back).
