UAE e-Invoicing API for Custom & Legacy System Integration

Not every system that needs to issue invoices is a mainstream ERP. Custom-built billing systems, point-of-sale platforms, legacy in-house software, and industry-specific tools (property management, hospitality PMS/POS, procurement platforms) all generate transactions that eventually need to reach a certified ASP in a structured, FTA-compliant format. For these systems, a pre-built connector often doesn’t exist — which is where an API-based integration path matters.

The TAQATUA API accepts invoice, credit-note, and master data from any system capable of making an HTTP call, and runs it through the same normalization, validation, and ASP-handoff pipeline used by TAQATUA’s native ERP connectors:

• Structured endpoints for invoices, credit notes, and reference/master data
• Field-level validation against FTA and Peppol (PINT AE) schema requirements before submission
• Consistent response and status codes so your system can confirm delivery or surface exceptions programmatically
• The same canonical data model used across TAQATUA’s ERP connectors, for consistent reporting regardless of source system

If your business runs a bespoke billing platform, an older ERP version without a pre-built connector, or a vertical-specific system, the API path lets that system participate in UAE e-invoicing compliance without a parallel manual process. It’s the same integration TAQATUA offers for SAP, Oracle, Microsoft Dynamics, Odoo, and Zoho — just reached through direct API calls rather than a native connector.

Every document submitted through the API is validated against current FTA and Peppol schema rules before it’s passed to your ASP, with data encrypted in transit and at rest, role-based access control, and a full activity log for every request — the same enterprise-security posture applied across the rest of the TAQATUA platform.
