Write to file via web interface?

Having trouble finding info on this… is it possible to write to a Figma file via a web interface beyond commenting/getting file lists? i.e. creating frames, pages, etc?

Trying to figure out if this is possible without a plugin UI inside Figma

It’s not entirely clear what you mean. In order for you to make changes to the file, you must use the Plugin API, post comments—REST API.

That answers my question — looks like the REST API won’t do what I’m hoping. Thanks!
