The SmugMug API. Hack - apikeys. To use SmugMug's API, you need an API key.
Each individual application or use of the API should use its own key. That means you'll have multiple keys if you're building multiple SmugMug applications. This provides us the ability to deal with API abuse and unapproved use. It also helps us track how it's being used so we can improve it. Commercial applications are not only allowed, but encouraged!
