Invoicing and electronic documents
Public-sector e-invoicing
Suppliers send nationally specified invoices through Peppol to the government’s GSIS receiving infrastructure; public buyers process them in their systems or EDHT.

myDATA
AADE’s electronic books and document-reporting platform. It exposes transmission channels for providers, ERP systems, timologio and other prescribed methods.

myDATA document interface
Tax-document submissions and their classifications have their own API model. MARK identifies an invoice registration; this is distinct from Peppol delivery.
myDATA XML and REST API · Official source: AADE · myDATA REST API v1.0.9 (reference model)
Treat public-sector invoice delivery and tax reporting as distinct parts of the workflow. A successful Peppol transmission does not on its own demonstrate that the document was issued or reported under AADE’s rules.
The myDATA API reference describes document categories, classifications and registration identifiers. It is a versioned reference, not a promise that every integration should still use that release; consult AADE’s myDATA portal for current technical versions.
