Fiscalizes the recepit taking in params and the extracted private key and public certificate.

Example

The following is the "minimal" example for fiscalizing a recepit/invoice.

You will need:

• Tax number (OIB) of the entity issuing the invoice (d.o.o., j.d.o.o., obrt, or d.d.)
• Tax number (OIB) of the operator
• Certificate from Fina in P12 format and it's password

params = %{
  tax_number: "23618229102",
  invoice_number: "1",
  business_unit: "1",
  device_number: "1",
  total_amount: 10000,
  invoice_datetime: ~U[2024-12-12 14:46:49.258317Z],
  sequence_mark: ExFiskal.Enums.SequenceMark.business_unit(),
  payment_method: ExFiskal.Enums.PaymentMethod.cards(),
  vat: [
    %{rate: 2500, base: 10000, amount: 2000}
  ],
  operator_tax_number: "37501579645",
  # Optional: Invoice recipient's OIB for B2B transactions (v2.6 spec)
  # Note: Cannot be used with payment_method: "T" (Transaction Account)
  oib_primatelja_racuna: "12345678901"
}

certificate = File.read!("/tmp/cert.p12")
password = "ExamplePassword"

# First extract the certificate keys
certificate_data = ExFiskal.extract_certificate_data!(certificate, password)

# Then fiscalize with the extracted keys
ExFiskal.fiscalize(params, certificate_data)

Parses the XML response from the fiscalization service and extracts the JIR (Jedinstveni identifikator računa / Unique Invoice Identifier).

Parameters

• xml_response - The XML string response from the fiscalization service

Returns

• {:ok, jir} - Returns the JIR string if found
• {:error, reason} - Returns an error if parsing fails or JIR is not found

Example

iex> xml = File.read!("priv/examples/response.xml")
iex> ExFiskal.parse_response(xml)
{:ok, "a70a985a-8882-4390-83e6-3a091970ed99"}
