Diligent

Diligent Corporation is a governance, risk, and compliance (GRC) software company best known for its board management portal (Diligent Boards / Boardbooks) and the broader Diligent One Platform, which unifies board management, enterprise risk, audit, compliance, entity management, and ESG. The board portal itself is a security-hardened product with no public developer API - it is integrated through SSO (SAML 2.0), SCIM provisioning, and packaged connectors (Okta, Microsoft 365/Teams, Zoom, DocuSign). Diligent does, however, publish a real developer portal at developer.diligent.com covering the GRC side of the platform - the HighBond (Diligent One) REST API for audit/risk/compliance data, a GraphQL Entities API for legal-entity and subsidiary management, an ESG API for activity/usage data, and a Workflow API for jobs, tasks, and campaigns. API access is customer/partner-gated (a HighBond API key or SSO-scoped token is required) and pricing is quote-based via Diligent sales.

Diligent publishes 4 APIs on the APIs.io network. Tagged areas include Governance, Risk, Compliance, GRC, and Board Management.

Diligent’s developer surface includes documentation and 8 more developer resources.
