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.

Partners working with other PSPs can also use Viva’s standalone Fiscal API to transmit data to regulators and receive valid receipt information.

The fiscalisation feature is currently available exclusively on our SoftPOS for Android. Please use this link to download the demo version of the Viva Terminal app with fiscalisation enabled and try it out in demo environment.

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.

Fiscalisation Data Parameters: Contains the core details required for tax compliance.
LineItems Array: An array of objects, each representing an individual item sold, including details such as description, quantity, price, and VAT.
Payment Array: An array of objects specifying the payment details, including payment method, amount, and references.

The fiscalisationData object consists of the below parts:

Understanding processingIndicators for Italy

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 Italy

For Italy (IT), the country code is 4954. Thus, the value of an unknown processing indicator in Italy is 4954000000000000.

Example for POS receipt processing indicator: 4954000000000001

The value 4954000000000001 is in hexadecimal format and needs to be converted to its decimal equivalent, which is 5283848262812434433. Therefore, the value to be included in the request body should be 5283848262812434433.

CCCC_vlll_gggg_txcc

Example

4954_2001_0001_0004

CCCC = 4954 | The two ASCII letters that specify the ISO country code (https://en.wikipedia.org/wiki/ISO_3166-1) (e.g. IT = 4954)
v = 2| This section is for versioning the tagging system (the current is the v2) (e.g. 2...)
lll = 001 or 002 | This section is for versioning the tagging system (the current is the v2) (e.g. 001)
gggg = 0000 | This item is used for global flagging. Flag can change the basic behavior of a given type, but will live the overall semantical meaning of a type the same. (e.g. voiding of a receipt)
txcc = 0001 | Represents the main kind of receipt processed by a POS system.

LineItems ProcessingIndicator for Italy

Format

The format of the processingIndicator parameter on line item level, should be the below.

CCCC_vlll_gggg_NNSV

Example

4954_2000_0000_0013

CCCC = 4954 | The two ASCII letters that specify the ISO country code (https://en.wikipedia.org/wiki/ISO_3166-1) (e.g. IT = 4954)
vlll = 2000 | This section is for versioning the tagging system (the current is the v2) (e.g. 2000)
gggg = 0000 | This item is used for global flaggin. Flag can change the basic behavior of a given type, but will live the overall semantical meaning of a type the same. (e.g. voiding of a receipt)
NN = 00 | The first part of the NNSV section, specify the nature of VAT.>
S = 1 | The second part of the NNSV section, specify the type of the service.
V = 3 | The third part of the NNSV section, specify the type of the VAT.

In this example, the generated number 4954200000000013 for LuneItem processing indicator is hex and should be converted to decimal number (5283883447184523283). So the value that should be passed through in the body request is 5283883447184523283.
