API Integrations · SIERET v2 / SIENEV v1

Production-grade connectors to SIERET v2, SIENEV v1 and electronic invoicing — built for enterprises that cannot afford a missed transmission.

Government APIs are notoriously brittle, undocumented and unforgiving. Blockia's integration layer abstracts SIERET v2, SIENEV v1 and electronic invoicing endpoints behind clean, typed interfaces — with automatic retries, idempotent submissions, encrypted payload caching and audit-grade logging. What used to take a year of integration work now ships in weeks, and survives every regulator-side change.

Already in production with enterprise clients transmitting to Colombian fiscal and customs systems.
