Calm

Calm is a leading consumer mental-wellness company whose app offers guided meditations, Sleep Stories, breathing programs, mindfulness masterclasses, and soundscapes.

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 1 API on the APIs.io network: Partner 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.
