⚡ Reliability
Best When
You need legally binding eSignatures with enterprise-grade audit trails, compliance certifications, and robust agent automation capabilities.
Avoid When
You need simple PDF handling, internal approvals only, or have budget constraints.
Use Cases
- • Automating contract generation and sending for signature from agents
- • Tracking envelope status and signature completion in workflows
- • Embedding signing experiences in applications via embedded signing
- • Managing document templates for repeated contract types
- • Bulk sending agreements to large numbers of recipients
Not For
- • Simple internal document approval workflows (overkill)
- • PDF generation without signature requirements
- • Small teams on tight budgets (pricing is steep)
Interface
Authentication
OAuth Authorization Code for user-context. JWT (Service Account) flow for server-to-server agent use. JWT is the preferred method for agents - no user interaction required.
Pricing
Free developer sandbox available for building and testing. Production requires paid subscription. Enterprise pricing can be significant.
Agent Metadata
Known Gotchas
- ⚠ JWT auth requires RSA private key management - secure key storage is critical for agents
- ⚠ Envelopes in 'sent' status cannot be modified - agents must void and resend if changes needed
- ⚠ Webhook (Connect) configuration requires a publicly accessible HTTPS endpoint with HMAC verification
- ⚠ Sandbox and production use different base URLs and separate accounts
- ⚠ API rate limits are per account across all integrations - multiple agents sharing an account can conflict
