About the Zoho Sign API

The Zoho Sign API is a RESTful API that allows developers to seamlessly integrate secure and legally binding e-signature functionalities directly into their own applications, websites, and custom workflows. It enables programmatic document creation, sending for signatures, managing document lifecycles (tracking status, updating, downloading), and template management. The API supports OAuth 2.0 for secure authorization, offers webhooks for real-time notifications on document activities, and facilitates embedded signing and sending experiences. Designed for developers, it provides comprehensive documentation, SDKs, and Postman collections to accelerate implementation. Zoho Sign API is compliant with major e-signature laws globally, including the ESIGN Act (USA) and eIDAS (EU), ensuring legal validity and security for electronic and digital signatures.
