Technical Setup & API Overview
Authentication
Contractbook supports SSO (Single Sign-On) for enterprise workspaces and uses standard API key authentication for API access. Full API documentation is available at the Contractbook developer docs.
REST API
The Contractbook API allows developers to programmatically manage documents and workspace permissions:
- Document management: Create, retrieve, update, and archive contracts
- Data extraction: Pull structured contract data fields (parties, dates, values, obligations) via API
- Workspace permissions: Manage user roles and access control programmatically
- Webhooks: Listen for contract lifecycle events (e.g., signed, expired, created)
Integrations
- HubSpot & Salesforce: Sync contract data bidirectionally with your CRM, trigger contract creation from deals, and update CRM records on signing events
- API-first: Build custom automations and embed contract workflows into your own internal tools
Security & Compliance
- SOC 2 certified
- Granular document and workspace-level permissions
- Secure electronic signatures compliant with eIDAS (EU) and ESIGN Act (US)
AI Data Extraction
The AI layer processes uploaded contracts to extract structured fields with ~70–80% accuracy on vendor agreements, reducing manual review overhead significantly.
