Connecting your business's myDATA

Updated 10 Nov 2026

  1. In AADE myDATA (REST API registration) create an API user for the business. You get a user_id and a subscription key.
  2. Business All-in-One → Company → myDATA settings → paste both values. They are stored encrypted.
  3. Press Test connection. If it succeeds, the first document read starts (a few minutes for one year).

Business All-in-One only reads. It does not transmit, characterise or change anything in your myDATA.

Refresh

Documents refresh automatically every few hours. Press Refresh now on the dashboard for an immediate update.

Revoking

You can delete the keys from Settings or disable the API user in myDATA at any time.
