Digital Signing API

A Digital Signing API enables businesses and developers to securely sign, verify, and manage digital documents through automated workflows and seamless system integration. It helps ensure document authenticity, integrity, and legal compliance using encrypted electronic signatures. With easy REST API integration, organizations can automate agreements, invoices, contracts, certificates, and approval processes while reducing paperwork and turnaround time.

The Turbo eSigner API-based version is very convenient for integrating with ERP, CRM, and other similar applications. The Turbo eSigner REST API allows you to digitally sign PDF files using a PFX (Personal Information Exchange) signature. This API supports token-based authentication, ensuring secure access to the service. The API can process unsigned PDF files as byte streams and returns the signed PDF file in bytes. It includes multiple features to customize the signature.

Each API request must include a valid token in the request header for authentication purposes. The token is issued upon successful login and must be renewed periodically.
