What is our eSignature API platform?
Our eSignature API connects your business with qualified trust service providers (QTSPs) and certified authorities (CAs) worldwide, enabling electronic signatures (eSignatures).
Qualified eSignatures (QES)
Seamlessly access services for all types of eSignatures
Whether users already have a digital certificate or need one issued, our platform provides seamless access to the services required for Qualified (QES) and Advanced (AdES) Electronic Signatures.
Advanced eSignatures (AdES)
The Old way
Scattered multi-app integration
Previously, businesses had to integrate separately with multiple QTSPs to access local eSignature methods or rely on providers that forced signers to create new accounts, even if they already had a preferred signing app.
The modern way
Access with a single API platform
With eIDEasy, a single API connects you to most providers and signing methods across Europe, Latin America, and Asia-Pacific.
“The partnership with eID Easy offers our clients a swift and easy solution to extend their services across the European continent. Everything needed is combined in one API, eliminating the need for multiple local integrations. This leads to lower costs and faster delivery.”
Who is it for?
Built for any business needing a reliable, trusted way to manage all types of eSignatures
We support multiple levels of eSignatures, tailored for different security and compliance needs:
- Simple Electronic Signature (SES)
- Advanced Electronic Signature (AdES Light)
- AdES with AATL Certificate
- Full AdES with Qualified Certificate
- Qualified Electronic Signature (QES)
How does it work
One integration, worldwide access
Your company integrates once with our API, and we handle the rest—connecting your business to the QTSPs in your users’ countries, managing certificate access, billing, and ensuring compliance with local regulations.
Access existing certificates
Enable users to use their USB, smart card, or cloud-based certificates issued by QTSPs instantly.
Unified integration
Integrate once with our API, and we manage all technical connections, certificate access, billing, and compliance across regions.
Enroll new users
Connect users without certificates to a QTSP for easy enrollment.
Flexible signature options
Support both QES and AdES for a customizable signing experience and access to a full range of signature legal validity levels
Time stamping
Trusted timestamps are added to documents, marking the exact moment of signing. A trusted authority digitally verifies these timestamps, ensuring legal validity and providing a verifiable signing date. Without a timestamp, the signature cannot be validated in the future as soon as the certificate has expired.
Advanced and qualified signatures
We support both, Advanced Electronic Signatures (AdES) for quick, flexible agreements and Qualified Electronic Signatures (QES) for legally binding, high-security contracts. This flexibility accommodates a range of use cases across different industries and jurisdictions.
Cross-provider access
Our API connects you to multiple QTSPs and electronic identity providers with a single integration. This eliminates the need for multiple integrations, simplifies provider selection, and offers global coverage for all your digital signing needs.
Multi-level signing
With our API, you can combine different types of eSignatures, including Simple, Advanced, and Qualified Electronic Signatures, in a single document. This feature is ideal for complex workflows that require different levels of authentication for multiple parties.
Batch (bulk) signing
Depending on the QTSP, we can enable batch signing where multiple documents are signed with one confirmation.
One-shot eSignature
Allow users to sign documents instantly. This streamlined approach is perfect for one-time agreements, NDAs, and quick approvals, enhancing time consumption.
Why businesses choose our eSignature API

Cost-effective pricing
Transparent pricing with no hidden fees ensures you only pay for what you need. We simplify commercial agreements by offering a single contract for all your eSignature needs.
