The 100% API architecture of Juniper Mist backs every visible feature in the Juniper Mist portal. Anything that you can do in the portal, you can automate at scale by using the API. Representational State Transfer (REST) is a stateless client/server architecture with a uniform interface. Since machines have no use for a user interface, APIs allow for a defined and faster way for machines to communicate with each other. APIs also enable you and other users to create your own way of interacting with systems and applications. You can even create custom features.
