## OpenAPI

````yaml api-reference/rbac/openapi.yaml POST /roles
openapi: 3.0.3
info:
  title: StarTree RBAC Manager API
  description: >
    Manage role-based access control (RBAC) in StarTree Cloud: policies, roles,
    the policies attached to each

    role, the subjects (users, groups, domains, service tokens) assigned to each
    role, and service tokens.


    Every request needs an `Authorization: Bearer <token>` header. See

    [Generating an API
    Token](/corecapabilities/security/manage-api-tokens#generating-an-api-token).


    Resources are identified by StarTree Resource Names (SRNs), for example
    `srn2:policy#my-policy` or

    `srn2:role#table-reader`. When an SRN appears in a URL path, encode the `#`
    as `%23`

    (`/policies/srn2:policy%23my-policy`).


    For a guided walkthrough of these endpoints, see

    [Using the RBAC API](/corecapabilities/security/using-rbac-api).
