I'm trying to make a call to add multiple users to a list using the format http://api.twitter.com/1/<owner_id>/<list_id>/create_all.xml?user_id=<user_id_1>,<user_id_2>,<user_id_3>
This seems to be failing and returning an HTML page from Twitter. My calls to add the same users to the same list one at a time using <list_id>/members.xml works fine. -- Twitter developer documentation and resources: http://dev.twitter.com/doc API updates via Twitter: http://twitter.com/twitterapi Issues/Enhancements Tracker: http://code.google.com/p/twitter-api/issues/list Change your membership to this group: http://groups.google.com/group/twitter-development-talk
