# VSP OpenAPI

## Overview

VIDA’s VSP Open API is a powerful, secure API designed to simplify and streamline digital signature workflows for clients who wish to incorporate VIDA’s e-signing capabilities directly into their platforms. By offering a full suite of tools, the API enables every step of the document signing process, from document preparation and signature initiation to final delivery.

The VSP Open API supports an end-to-end digital signing workflow, including:

1. **Identity Verification**: VIDA’s KYC process verifies user identity as part of the signing process.
2. **Envelope Creation**: Enables envelope creation for process documents, providing flexibility for single or multiple documents.
3. **Envelope Distribution**: VIDA manages secure distribution of documents to recipients via email or URL.
4. **Document Signing**: VIDA handles document previews, custom signature styles, and an intuitive signing interface.
5. **User Authentication**: With secure OTP or biometric authentication, VIDA ensures signer identity integrity.

Overall, the VSP Open API extends VIDA’s Sign Platform (sign.vida.id) capabilities to the client’s own applications, providing robust e-signing features with minimal development needs.
