LC API

The main purpose of Verestro Lifecycle API & SDK web service is to add and manage user and payment cards in a safe way. All data are transfered to Verestro Data Core system which is placed in PCI compliant zone and is fully secure.

LIfecycle API is an internal service secured by x509 certificate, which increases the safety of transported data. The API communicates with the data storehouse called DataCore. DataCore is internal service and one of crucial components of Verestro's product line-up. Its main responsibility is to provide secure, PCI-DSS compliant storage for cardholder data. DataCore manages the status of the user and their aggregates. All other product in implementation connect to DataCore which returns information about the user and his aggregates.

THC (Transaction History Core)

KYC (Know Your Customer)

After logging in, the user goes through an intuitive process KYC, which allows for instant identity verification in accordance with the AML (Anti-Money Laundering) regulations. The system automatically analyzes user data, ensuring the highest level of security and protection against financial fraud.

In order to pass KYC, it is necessary to take a photo of an identity document and pass liveness. Liveness is a biometric verification that involves the user recording a short video of themselves showing their face and making gestures as instructed.
