This package defines some endpoints which has some (limited) knowledge of the API schema used by SKAT. The classes are:

• dupla.payload.KtrPayload
• dupla.payload.LigPayload
• dupla.payload.MomsPayload
• dupla.payload.KtrObsPayload
• dupla.payload.LonsumPayload
• dupla.payload.SelskabSambeskatningPayload
• dupla.payload.SelskabSelvangivelsePayload

Please c.f. the docs of the respective classes for more information on what each endpoint is for. Each payload model is a Pydantic model, so inputs are validated.

The base api access class can be used as following. In this example, we access the VAT (Moms in Danish) endpoint.

from datetime import date, timedelta
from uuid import uuid4
import dupla
from dupla import DuplaApiKeys

api = dupla.DuplaAccess(
    transaction_id=str(uuid4()),
    agreement_id="your-aftale-id-goes-here",
    pkcs12_filename="path-to-cert-file",
    pkcs12_password="goodpassword",
    billetautomat_url="https://bat.skat.dk/realms/oces/protocol/openid-connect/token",
    jwt_token_expiration_overlap=5
)

# lets see if this company (se_number 98765432) has done any VAT the last year
kwargs = {DuplaApiKeys.SE: ["98765432"],
          DuplaApiKeys.AFREGNING_START: date.today() - timedelta(days=365),
          DuplaApiKeys.AFREGNING_SLUT: date.today()}
payload = dupla.payload.MomsPayload(**kwargs)

data = api.get_data(payload)

print(data)
