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.
