The API has lovely "read" and "write" actions, but it's not possible to edit or remove existing posts. Is there any chance of an "update" or "delete" action to allow you to do this?
Because Tumblr provides its JSON read output as a Javascript variable (complete with a semicolon at the end) it won't work out of the box with the json-php library--and possibly other json libraries. My quick fix was to use str_replace to remove the non array pieces:
I'd like to bring my Digg posts over to Tumblr with their blog posting system, but it seems like the only way to add Tumblr is through an XML-RPC address. Let me know how I can get to this. If the API is open, I would imagine that this isn't too hard to do.
I've been stymied for awhile about how to best integrate Tumblr into my site. Because I have lower level directories on my domain that I can't move the standard "point your domain at Tumblr servers" method wasn't going to work. The new API gives me all the access I could ask for.
I love how you've provided both XML and JSON output, and the documentation is fab!
