Yousign provides electronic signature and related trust services such as identity, company, bank-account, and document verification. It also offers electronic sealing and archiving features for document workflows.
Yousign exposes one documented developer integration surface: a REST HTTP API (Public API v3) for e-signature, verification, sealing, archiving, templates, users, workspaces, and webhook subscription management, authenticated with a Yousign-issued API key.

Create a key for the desired environment (sandbox or production), choose its scope and permissions, then copy the key and send it as Authorization: Bearer <apiKey>. Base URLs are documented in Environments.
