Overview

Viva Fiscal API is designed to help businesses comply with fiscalization laws, especially in countries with strict regulations on tax reporting and cash register security. It acts as an intermediary between a company’s point-of-sale (POS) system and government tax authorities, ensuring that all transactions are accurately recorded, securely signed, and transmitted in compliance with legal requirements.

Benefits

• Legal Compliance – Many countries, such as Germany and Austria, enforce strict fiscal laws requiring businesses to securely record transactions. The Viva Fiscal API ensures businesses meet these regulations seamlessly.
• Security & Integrity – Protects against tax fraud by ensuring all sales data is securely stored and transmitted in an immutable format.
• Automation & Efficiency – Reduces manual errors and administrative burdens by automating tax reporting.
• Seamless Integration – Enables businesses to integrate fiscal compliance into their existing POS systems with minimal effort.
• Handle Government-Mandated Requirements – Some countries require certified fiscalization solutions for all POS systems.

POS Integrations

Viva offers Auto Fiscalization functionality within its POS integrations, providing an electronic fiscalization service that allows businesses to record, process, and store transactions digitally. This ensures transparency, accuracy, and compliance without complex procedures.

Fiscalization is available through:

• Local Terminal API – Local ECR integration
• InterApp Integration – Terminal/SoftPos Interapp integration
• Cloud Terminal API – POS integration via Cloud Terminal API

Merchants and ISV partners do not need to allocate resources for fiscalization integration, as all transactions are automatically fiscalized during payments.

How to Fiscalize POS Payments

Ensuring that a payment is tax-compliant is quite straightforward. Your integration remains the same, with just one additional object added to your sale requests. This object(fiscalisationData) contains essential data, including the items sold, the payment amount for each item, and the corresponding VAT details. You can find the object structure and its parameters here.

The fiscalisationData is same across all types of POS integrations. By understanding what to include in your requests, you can seamlessly integrate fiscalisation into Viva’s any POS integration. Viva Fiscalisation handles the compliance process by signing the transaction with the relevant authorities. It then returns the receipt details, including the required signature for tax authorities. This information must be printed on the receipt and provided to the customer.

Fiscalisation Data Object

The table below presents the parameter details for the fiscalization data. The fiscalization data object comprises three main components.

1. Fiscalisation Data Parameters: Contains the core details required for tax compliance.

2. LineItems Array: An array of objects, each representing an individual item sold, including details such as description, quantity, price, and VAT.

3. Payment Array: An array of objects specifying the payment details, including payment method, amount, and references.

The fiscalisationData object consists of the below parts:

Fiscalisation Data Parameters

The fiscalisationData object contains the below parameters.

Example

The order includes two products, one Coffee Latte and two Coffee Cappuccino, with grand total amount of 20 euro (1 item Coffee Latte x 10 euro + 2 Coffees Cappuccino x 5 euro). The payments array, will be the below:

{
   "processingIndicator":"5139205309155246081",

   "receiptUniqueReference":"fiscal-12345678",
   "lineItems": [{...}],  //array of objects
   "payments": [{...}]   //array of objects
}

LineItems Array

Inside the fiscalisationData object, the LineItems array holds the product/item details that the invoice includes.

Example

The order includes two products, one Coffee Latte and two Coffee Cappuccino, with grand total amount of 20 euro (1 item Coffee Latte x 10 euro + 2 Coffees Cappuccino x 5 euro). The line item array, will be the below:

"lineItems":[

Understanding processingIndicators for Austria

As you might have already noticed, the FiscalisationData object contains a parameter called processingIndicator. This parameter exists in the main object, inside lineItems object, and payments object.

Receipt processingIndicator: The ProcessingIndicator in the ‘main body’ indicates the receipt type and defines how it should be processed by the Viva Fiscalisation. The data type is Int64 and contains the country specific code, which is a value following the ISO-3166-1-ALPHA-2 standard converted from ASCII into hex and used as byte 8 and 7. For definitions regarding national laws, please refer to each country seperately.

LineItems processingIndicator: The ProcessingIndicator in the ‘lineItems’ object defines the type of service or item in the line item block and thus how Viva processes the individual receipts with regards to receipt generation. The data type is Int64 and contains a country specific code which is a value following the ISO-3166-1-ALPHA-2 standard, converted from ASCII into hex and used as byte 8 and 7.

Payments processingIndicator: The ProcessingIndicator in the ‘payments’ object indicates the type of payment within the pay items block and defines how the Viva Fiscalisation processes the individual payment in terms of the receipt. The data type is Int64 and contains a country specific code which is a value following the ISO-3166-1-ALPHA-2 standard, converted from ASCII into hex and used as byte 8 and 7.

Receipt ProcessingIndicator for Austria

For Austria (AT), the country code is 4154. Thus, the value of an unknown processing indicator in Austria is 4154000000000000.

Example for POS receipt : 4154000000000000

The value 4154000000000000 is in hexadecimal format and needs to be converted to its decimal equivalent, which is 4707387510509010944. Therefore, the value to be included in the request body should be 4707387510509010944.
