  title: Clerk Backend Allowlist & Blocklist Organizations API
  description: 'The Clerk Backend API manages Clerk''s authentication and user management resources server-side: users, organizations and memberships, sessions, clients, sign-ups, JWT templates, JWKS, email/SMS verification and templates, allowlist/blocklist identifiers, invitations, SAML/enterprise connections, OAuth applications, and Svix-powered webhooks. The base URL is https://api.clerk.com/v1 and every request (except GET /jwks and the public interstitial) is authenticated with your instance Secret Key passed as `Authorization: Bearer sk_...`. This description is grounded in Clerk''s published OpenAPI spec (github.com/clerk/openapi-specs, bapi) but is a curated subset covering the primary resource groups; it does not enumerate every parameter or schema property. Verify the current version-dated spec on GitHub for the authoritative contract.'
