Droplock, a Dropbox hack, wins BattleHack LA!

I spent the weekend at BattleHack LA, a hackathon put on by Braintree, and I had a great time working with a number of teams who integrated Dropbox into their projects.

How Cloud Cannon uses webhooks

NOTE: This is a guest post by Mike Neumegen, co-founder of Cloud Cannon, a CMS built on top of Dropbox syncing.

With the addition of webhooks to the Dropbox API, there’s a faster way. Now you can receive instant notification when a user changes files in their Dropbox.

We’ve been using webhooks at Cloud Cannon since its beta in April and have learned how to really leverage them.
