Automate myAADE with a workflow

A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

• New debts in Ο Λογαριασμός μου, every morning

  Build this

  Starts

  Every weekday at 8:00 (Europe/Athens)

  Step 1

  Get the debts listed under Οφειλές εκτός ρύθμισης και πληρωμές.

  Step 2

  Keep the debts that were not there on the last run.

  Step 3

  Email you each new debt with its description and amount, and the new total.

• Arrangement installments, sent to your accounting system

  Build this

  Starts

  Every Monday at 9:00 (Europe/Athens)

  Step 1

  Get each arrangement in Οφειλές σε Ρύθμιση και Πληρωμή with its next installment.

  Post arrangement, ΤΡΟ, installment amount and due date to your accounting system's webhook.

• New messages in Τα Μηνύματά μου, summarized

  Build this

  Starts

  Every day at 7:30 (Europe/Athens)

  Step 1

  Read the messages in Τα Μηνύματά μου received since yesterday.

  Step 2

  Step 3

  Summarize each message in a sentence and email you the summaries with the full texts.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get debts outside an arrangement” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "www1.aade.gr/get_debts_outside_arrangement",
    "input": {}
  }'

{
  "status": "completed",
  "data": {
    "debts": [
      {
        "description": "ΦΠΑ, tax period 2026-09",
        "amount": 4812.4
      },
      {
        "description": "Παρακρατούμενοι φόροι μισθωτών, tax period 2026-09",
        "amount": 1265
      }
    ],
    "total": 6077.4,
    "currency": "EUR"
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

MyAADE’s own options

AADE runs a REST API for myDATA, with a registration form for its test (Dev) environment. The myAADE portal offers Ο Λογαριασμός μου, Τα Αιτήματά μου (my requests), Τα Ραντεβού μου (my appointments), Μητρώο & Επικοινωνία and Εφαρμογές (applications) as screens you sign in to, and its pages mention no API for debts, arrangements or tax clearance.

Signing in to myAADE

myAADE signs you in on the TAXISnet page at login.gsis.gr with a user name (Όνομα χρήστη) and password (Κωδικός πρόσβασης). With Fous you sign in there once with your own TAXISnet account, and the login is sealed with AES-256 and never shown to your code or AI agents. When the session expires, Fous signs back in.

Worth knowing

Installments are not paid in myAADE

Arrangement installments cannot be paid through myAADE. You pay them at a bank with the Ταυτότητα Ρυθμισμένης Οφειλής (ΤΡΟ), which stays the same until the arrangement is paid off.

A bilateral arrangement shows after one payment

A bilateral arrangement shows in myAADE only after the first installment is paid. Its ΤΡΟ, first due date and first amount arrive earlier as a message in Τα Μηνύματά μου.

Card payment only on your own filing

The «Αυτόματη πληρωμή με κάρτα / IRIS» link appears after a VAT or withholding return only when you file it with your own credentials, not through an accountant or representative.

Who gets a digital tax clearance

Overdue debts up to €30 in total still allow a certificate for most purposes. Debts in the out-of-court mechanism (ν.4738/2020) or a court arrangement (ν.3869/2010) do not get one digitally.
