API reference

Invoice field mapper

JSON to UBL, CII, FatturaPA, Facturae or KSeF.

Map any B2Brouter JSON invoice field to its equivalent XML path in international e-invoicing standards. Toggle the format columns you need, search by field name, Business Term code (BT-1, BT-2…) or XML path, and click any cell to copy the path to the clipboard.

Supported formats: UBL 2.1, CII, Facturae 3.2.2, FatturaPA 1.2.3 and KSeF FA(3). PEPPOL BIS 3.0 and other UBL profiles inherit the UBL paths shown here. The matrix grows as new formats and Business Terms are documented.
