What is our eSealing API platform?
Our eSealing API platform enables businesses to apply electronic seals to documents automatically, ensuring authenticity, confirming the origin of the document, and preventing tampering.
Much like a traditional company stamp, an eSeal assures that the document hasn't been altered after it’s been sealed and you know exactly which company has created it. Whether it’s invoices, contracts, or other official documents, our API simplifies the process, allowing high-volume, automated sealing at scale.

“Ramirent needed a service for authentication and electronic signatures. eID Easy had a competitive package and supported all the Baltic countries, therefore the choice was obvious.”
Automate document sealing without human intervention
The eSealing API is ideal for businesses that manage large volumes of documents needing official authentication, including:
- B2C and B2B companies sending invoices or contracts; and
- industries like finance, procurement, and legal services requiring document verification.
Simple integration, global compliance
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.
Certificate issuance
Clients receive a company-specific certificate from one of our trusted providers.
API integration
Clients integrate the eSealing API into their document systems. Once set up, documents are automatically sealed using the company’s certificate according to the business workflow needs.
Private key storage in HSM
The certificate's private key is stored on a Hardware Security Module (HSM) for tamper-proof security. HSMs can be USB tokens or rack-mounted units in data centers, capable of processing many eSeals per second.
Bulk sealing
Documents can be eSealed in high volumes automatically without manual intervention.
