Yousign

Electronic signature and digital trust platform for businesses to collect signatures, verify identities, and apply electronic seals to documents. Integrates with existing tools via REST API or embedded iFrame, supporting full signature workflows from preparation to completion.

Yousign serves over 30,000 European companies and processes more than one million signature requests per month. Headquartered in France, it complies with eIDAS and European data protection rules, offering an alternative to US-centric providers for teams that need data residency and EU regulation alignment.

Key features:

• Public API v3 with code examples and recipes for Node.js and other languages
• iFrame SDK for embedding signature flows with white labelling and custom branding
• Webhooks for real-time status updates and tracking
• Identity verification and electronic seals for document authentication
• Integration with CRM, ERP, HR tools, and custom applications

Use cases include HR onboarding and employment contracts, sales agreements in CRMs, KYC and KYB workflows, and document authentication for compliance. Developers typically integrate in under a week using the API or embedded iFrame, with webhooks to build dashboards and automate downstream processes.
