REST API

Unravel's REST API allows you to query and collect data from your cluster, using either HTTP or HTTPS protocol. The API returns information similar to what you see in Unravel UI. All requests and responses are in JSON format.

Authentication

  • If you're running the API through Unravel UI's Manage | API, authenticate through the UI; be sure to select the correct protocol (HTTPS or HTTP).

  • Authenticate through the /signIn request.

Your access level is determined by your RBAC role. Unravel Server returns a session token which you then include in all subsequent requests.RBAC roles

Base URL

All endpoints are relative to the base URL, http://unravel-host:3000/api/v1 or https://unravel-host:3000/api/v1

The API adheres to the standard create-read-update-delete (CRUD) semantics in which the request path defines the endpoint, and the method specifies the action to perform on the resource.
