Frequently asked questions about the Extra service API Business

We will allow business and corporate entities that are account holders or have account authorization to use the KB API. Additionally, accounts must be managed in the KB+ app.

If you have accounts in the KB+ app, simply select the extra service option in our app and sign the agreement. You can then activate the service in your accounting or other system.

You can choose from the Basic, Plus, and Pro plans. They are categorized based on which services you’ll use and how you’ll use them.

It depends on which ES API Business plan you choose. Our API services are billed according to the current price list.

You can find an overview of the systems and applications that support our API services here on our accounting systems and other applications page.

This service is primarily intended for self-employed individuals or legal entities. However, if you have an active Premium subscription, we will allow you to use the ES API service even if you are a non-business individual.

If you have questions about your accounting system or any other application, we recommend that you always contact your accounting system’s support team first. For questions regarding the ES API Business and settings in KB+, please contact kbplus@kb.cz.
