I would like to send Drafts to Dropbox locally and without a network connection which the Dropbox API requires.
Currently I use 1Writer’s x-callback-url which works well enough but the app is stagnant and I would prefer to use Drafts rather than rely on another app.
@sylumer is correct, Bookmarks are you option to write directly to Dropbox while offline. You will, of course, need to have the Dropbox app installed. More overview of the options for working with Dropbox (and sample actions) in our integration guide:
