  notes: >-
    REST APIs use HTTP Basic authentication. The Account SID is the username (public
    identifier, similar to a public key) and the Auth Token is the password (secret
    credential). The pair is base64-encoded and sent in the Authorization header:
    `Authorization: Basic base64(AccountSID:AuthToken)`. Access tokens support scoped
    permissions ("Scoped Tokens") with per-category read/write toggles for least-privilege
    integrations. The hosted MCP server (mcp.impact.com) uses OAuth 2.1 separately.
