2026

September 2026 update v3.0 myDATA 2.0.2

New documentation site, replacing the Word files:

  • Two APIs, fully documented: Provider API and Onboarding API (with webhooks), each with OpenAPI and a Postman collection. The Provider collection runs 9 scenarios in sequence, with tests on every call.
  • 32 ready-made JSON examples, checked automatically (amounts, VAT, totals, classifications). The 25 AADE tables are grouped into 6 pages.
  • FAQ: more than 100 questions from real developer cases.
  • New certification: no appointment, basic scenarios only, online request. Modules (card, food service, goods movement, B2G, OSS, Onboarding) are declared, not certified.
  • Stated explicitly: only types 1.1 to 11.5 are issued through a Provider.
  • Newly documented: multipleConnectedUids, correlatedInvoicesUids, CancelReceivingNote, GetInvoice/{uid}/{fileType}, GetInvoicePdfByAuthenticationCode, GetCreditsBalance, the Provider validation rules and the AADE error codes.
  • Corrections: SendInvoices takes one document per call · GetOpenTables / GetOpenOrdersForTable are GET · HEX/BASE64 per NSP fixed (Viva, Cardlink, Worldline, Other HEX) · digitsItemPrice defaults to 2.

  • Fields: receivingNotePurpose (required on 10.1 / 10.2, table 8.24), otherReceivingNotePurposeTitle, nonObligatedRecipient, withoutDigitalTransportTracking. AADE error 290.
