Appendix B: Registering and Managing Your Messenger Connect Applications
|Current information about Live Connect is now available in the Windows Live Developer Center. The information in the following sections is provided for legacy purposes only.|
All programmatic interaction with Windows Live requires a client ID, which uniquely identifies your application to Windows Live. Your application must include the client ID in every request that it sends to the Messenger Connect API service and in every application-specific Windows Live URL.
You obtain a client ID by registering your application with Windows Live at the application management site (https://manage.dev.live.com). During registration, you supply values for various application properties, such as your application's name, logos, domain name, and other information. You can register your application initially by supplying a minimal set of information. However, if you decide to put your application into production, you must provide all the required application settings.
