Integration specifications

Production gates, not live connections

RRA EBM 2.1

CIS approval, VSDC initialization and signed authority responses. Apply the approved item catalog and the 24-hour offline limit.

Payment lifecycle

Verify provider identity and amount. Deduplicate event IDs. Poll payment status if callbacks are missed. Fiscal acceptance is recorded separately.

Portable fiscal core

SQL aggregates and 500-row cursor exports. Rwanda-approved hosting and cross-border authorization must be established before live deployment.
