Quick Start

To make it easier for you to find your way around, we have divided the documentation into several key sections. Choose the one that best suits your needs.
 

For Integrators and Developers

This section is intended for technical staff implementing the solution and connecting to our system.

• API Specification A detailed overview of all available API methods. Here you will find specific request and response examples, parameter explanations, and everything you need for a successful backend connection.
• XML Guide and Examples A detailed guide for creating a valid XML document to send to us. Includes the structure, mandatory fields, and ready-made XML file examples that you can download and test.

Document Flow, Statuses and Errors

Understanding the lifecycle of a document (invoice) is crucial. Documents can pass through various stages, and it is important to distinguish between exchange errors (within our system) and fiscalization errors.

• Document Status Here we explain the entire document flow from sending to delivery. Find out what each status means and what your next step is if a document gets stuck.
• Fiscalization Errors A guide intended for both integrators and end-users. Important: Fiscalization errors and success messages come exclusively from the Tax Administration. Look up the error code here to find out exactly what needs to be corrected on the invoice.
