Documenso Security Basics

Documenso Security Basics

Output

• A least-privilege Documenso configuration with scoped secrets, signer/document access controls, and an incident/revocation path.
• A tested boundary for document authorization, webhook validation, and safe audit logging.

Examples

Create a development document with a synthetic signer, validate that only its intended role can view or act on it, and verify any webhook signature before processing. If a token, signing URL, or document is exposed, revoke/contain access and follow the incident procedure before attempting cleanup.

Overview

Essential security practices for Documenso integrations: API key management, webhook verification, document access control, and self-hosted signing certificate configuration.

Prerequisites

• Documenso account with API access
• Understanding of environment variables and secret management
• Completed documenso-install-auth setup

Instructions

Step 1: API Key Security

// NEVER hardcode keys
const BAD = new Documenso({ apiKey: "api_abc123..." }); // Exposed in source

// ALWAYS use environment variables
const GOOD = new Documenso({ apiKey: process.env.DOCUMENSO_API_KEY! });

Key management rules:

• Store in .env (never committed) or a secrets manager (Vault, AWS Secrets Manager)
• Use team-scoped keys for team resources, personal keys for personal documents
• Rotate keys on employee offboarding -- revoke in dashboard immediately
• CI/CD: use masked/encrypted secrets (GitHub Secrets, GitLab CI variables)
