Update Plugin Marketplace
Set the default installation setting of one of the organization's own plugin marketplaces. Every Plugin in it without a setting of its own gets this default as its organization-wide setting, including Plugins added later.
Pass it as default_installation_preference. A member's personal marketplace
cannot be updated here (403).
Accepted credentials: an Admin API key with the write:plugins scope.
Every request must include the beta header anthropic-beta: ce-plugins-2026-09-01. A request without it returns 404, exactly as if the endpoint did not exist. The Plugins API is in beta and is available to Claude Enterprise organizations only. It is not available to Claude Platform (Claude Console) organizations, or to organizations with HIPAA readiness enabled.
