Calm

Calm is a leading consumer mental-wellness company whose app offers guided meditations, Sleep Stories, breathing programs, mindfulness masterclasses, and soundscapes. Beyond the direct-to-consumer app, Calm sells two B2B products: Calm Business, which delivers the Calm experience to employers as an employee wellness benefit, and Calm Health, a clinical mental-health offering for health plans and large self-insured employers. Both are powered by the Calm Partner API, an OAuth 2.0 client-credentials REST surface that partner HR and benefits systems use to provision, link, and cancel Calm subscriptions for their members, alongside SAML 2.0 IdP-initiated SSO and SFTP eligibility-file uploads. Calm is a portfolio company of Lightspeed Venture Partners.

Calm publishes 2 APIs on the APIs.io network: Authentication API and Subscriptions API. Tagged areas include Company, Mental Health, Wellness, Meditation, and Mindfulness.

Calm’s developer surface includes documentation, API reference, getting-started guide, support, pricing, authentication, sandbox, and 16 more developer resources.
