FAQ
This page covers the typical questions about the web validator, API, accounts, and downloads. For guided step-by-step instructions, the documentation page is the better starting point.
Can I use the API directly without a customer account?
No. API usage requires a registered customer account with a suitable plan.
Is the web validator an open API?
No. The free validator is intentionally provided as a web form with rate limiting and bot protection, not as a public API.
What is the difference between the end-customer and technical areas?
The end-customer area helps users understand and validate e-invoices. The technical area targets integrators who want to run the API in production.
Can I use the validator without registration?
Yes. Guests can run up to three validations per hour and only see the validation status. With an account you get a higher quota and detailed findings.
Can I use the API and web validator with the same account?
Yes. A free account can later be upgraded to an API plan in the billing area.
Which files can I download?
API customers can download XML invoices generated through the API in the portal. The OpenAPI specification is also available as a download.
