Signature API for Your Systems

Everything You Need to Know About the Signature API

eIDAS Certified

Our solution is eIDAS-certified for qualified electronic signatures (QES) that are legally binding and recognized across Europe.

Two Signature APIs Available

Choose the API that fits your needs: the Workflow API for flexible signature processes, or the CSC API for secure, standardized remote signing.

TSP Technology Without Certification

With TSPaaS, you can offer qualified trust services yourself without certification and without high costs.

Fully Scalable

With the Signature API, you can not only offer QES, but also integrate identification and authentication services into your solution.

Workflow API (High-Level):

You can use the Workflow API to quickly and easily integrate preconfigured signature processes into your application. It’s ideal if you want to deploy ready-made workflows without having to develop or configure complex procedures yourself. This allows you to launch and manage signature processes efficiently with minimal implementation effort.

CSC-API (Low-Level):

The CSC API gives you maximum flexibility in implementing custom signature workflows. Based on ETSI standards for remote signatures, it enables you to tailor every process precisely to your requirements — from integration into existing systems to the design of complex workflows. This way, you maintain full control over the entire signature process.

How does TSP as a Service work?

TSP as a Service is designed to integrate SIGN8 trust services directly into your own product. This allows your end users to sign documents directly within your solution, while the signature process is handled in the background via API using the SIGN8 infrastructure.
With TSP as a Service, you not only save significant time and capital – you also avoid having to deal with complex regulatory and technical implementation details.
