Introduction

This document describes the relying party service interface protocol of LVRTC e-Identity
platform and provides information for integration.

The interface offers the entry point to eParaksts mobile and eID Scan main use cases, i.e. authentication and
signing.

API is a REST WEB service that provides operations using HTTP requests.

The Goal

API is designed to extend the current API provided by LVRTC e-Identity platform:

1. Integration Platform operations with eParaksts mobile and eID Scan application require a user redirect to
   eparaksts.lv services. In case of Open Banking a total number of redirects increases
   resulting in 6 or more redirects.
   • This API solves this situation by handling the communication with eparaksts.lv
     services internally.
2. SeeWhatYouSign principle currently is not provided by the signature procedure of LVRTC
   e-Identity platform.
   • This API solves this situation by using the eParaksts mobile and eID Scan transaction signing
     functionality, where payment details together with a control code are displayed to
     the end user in the application.

Known Issues

There are several known issues:

1. eParaksts mobile application uses a signing certificate that allows to produce
   Advanced Electronic Signature (AdES).
2. Qualified Electronic Signature (QES) is supported only with eID Scan application.
