Over 2500 Developer Edition orgs were enabled with the REST API festure earlier this week when we launched the REST API Developer Preview!
The recorded webinar is now available for viewing, along with slides and other resources right here. In addition to the webinar page, we have a resources page with code samples and pointers to articles and how to get started using the API. If you have any specific questions or comments, be sure to hit the new REST Integration discussion group.
If you didn't sign up for the initial webinar/preview, you can sign up here to get a Developer Edition account enabled. Get started using this new technology tool in your developer environment!
