(1) Standard software

The Contractor shall provide the Customer with the programming interface NextGen API via StepOver's Nuget Feed, with associated documentation for integrators, libraries and programming examples in the agreed main version free of charge.

(2) Type and scope of the service

The programming interface enables the client to capture advanced handwritten electronic signatures and embed them in PDF/a-compliant documents. When capturing advanced electronic signatures, the biometric data is securely encrypted. Among other things, a cross sum (hash) is calculated over the entire document, including signatures already made, which is used to determine the integrity of the document.

In addition, the NextGen API can be used to read and change the configuration of the pad.

(3) Functions

The NextGen API offers functions that can be used for the automation of document workflow processes and integration into an existing external application. The functions listed here are not complete and are only described in very general terms:

  • Search and selection of the pad in the network

  • Uploading documents

  • Uploading XML files containing a PDF document to be signed and instructions for finding signature positions

  • Control of the signature process

  • Downloading the signed documents

  • Communication with the secure NG Pad operating system

  • Display advertising videos and photos and much more

  • Read out and edit pad settings

To automate signature processes, the document must be transferred using XML (with corresponding workflow information) or a PDF document with existing digital signature fields.

(4) System architecture

NextGen-API is a programming interface that is available as a 64-bit version and is compatible with the Windows, Linux and macOS operating systems. The NextGen API is only available as a .NET version.
