Integrate Advanced Electronic Signatures directly into your systems and simplify signing processes with secure identification and OTP authentication.

Signing a document often still requires too many steps: printing, scanning, emailing and manual processes that slow down activities and make document management more complex.
For this reason, Openapi is expanding its API Trust solutions catalog with the new Advanced Electronic Signature with OTP API (AES): a service that allows you to integrate a secure, traceable and easy-to-use digital signing process directly into your systems.
The Advanced Electronic Signature (AES) makes it possible to uniquely link a signature to its signer, providing greater security and evidentiary value compared to a simple electronic signature.
With Openapi's API, the signing process is completed through an OTP (One-Time Password) sent via SMS to the signer's phone number. This makes it possible to verify the signer's identity and complete the signing process entirely online, without the need to print or physically manage documents.
The solution is designed in compliance with the eIDAS Regulation, ETSI standards and GDPR and records information related to the signing process through an audit trail, ensuring traceability and enhanced security.
The value for your business
Integration is simple: through the API, you can send the document to be signed together with the signer's details and the information required to configure the signing process.
The API generates a personalized link to the signing platform, through which the signer can view the document, complete OTP authentication and apply their signature.
The process can be configured according to the needs of your application:
It is also possible to use an identification process with liveness to further increase the security level of signer identification.
The new AES with OTP API is part of the Openapi API Trust Suite: a set of solutions designed to integrate verification, identification and digital signing services directly into your systems.
If you want to digitize document management and offer your users a secure and simple signing process, Openapi's Advanced Electronic Signature with OTP API allows you to integrate signing directly into your platforms, applications and business processes.
Reduce manual steps, increase the security of signatures and bring electronic signing directly into your digital workflows.
