  title: Calm Partner Authentication API
  version: v0
  description: The Calm Partner API is the OAuth 2.0 client-credentials REST surface that powers Calm Business and Calm Health B2B integrations. Partner systems (HR platforms, benefits administrators, and health plans) use it to authenticate, provision and link a Calm subscription for one of their users, and cancel that subscription to prevent auto-renewal. It complements Calm's SAML 2.0 IdP-initiated SSO and SFTP eligibility-file mechanisms documented in the Partner Portal.
