sproof Widget Integration and API
- The Signing Widget from sproof enables the direct integration of eIDAS-compliant electronic signatures (FES, QES) in any application and website. In contrast to conventional signature workflows, where signers receive an invitation to sign via separate channels such as email or SMS, users remain in the existing environment with the Signing Widget .
The API allows the signing process to be seamlessly integrated into a system, with the user interface being customizable to enable customized user journeys. The Signing Widget is particularly suitable for web applications that regularly generate contracts or other documents that have to be signed by the users themselves.
