We ensured the integration of the CartaMe mobile app with the accounting system of the ZOOmartet retail chain, built on the Optima solution developed on the 1C platform, so that CartaMe users could become members of the chain's loyalty program and use a unified Loyalty ID as their discount card number.

The integration model was implemented based on the approach used in the Fizcult project, but adapted to the specific characteristics of the client's accounting system. On the CartaMe side, we prepared API exchange specifications, a test environment, and all necessary conditions for rapid onboarding. The work was carried out in close collaboration with the partner's team, ensuring coordinated and efficient integration.

The Optima system, on a schedule defined by the client, connected to CartaMe and retrieved a list of new users who had consented to participate in the ZOOmartet loyalty program. Unlike several other 1C-based integrations, in this project the client's accounting system immediately wrote the full user profile during the initial data exchange.

Additionally, a multi-consent mechanism was implemented in accordance with personal data legislation requirements. This enabled proper separation of consents for participation in the loyalty program, processing of personal data, and use of additional user information within the client's business processes
