Ways to work with AosEdge

You can work with AosEdge in three ways: via AosEdge UI, AosEdge API, and the AosEdge SDK tools.

• AosEdge API — the primary communication interface with the cloud. It is a REST API that allows performing any actions. Documentation about API can be found here: Aos API (aoscloud.io)
• UI — is a web application that uses AosEdge API and allows users to perform actions on AosEdge with GUI. It is designed to allow users to perform basic tasks without API.
• SDK — a set of command-line tools to help users perform AosEdge-related tasks on the client machine. Such as receiving user certificates, provisioning new units, and working with services.
