VAT Prices Calculations

Using our price endpoints, you may request the API to calculate VAT compliant prices for you.

Hot and Cold Price Calculations
Just as with validations, at VatZen we have a concept of 2 price types: Hot and Cold.
Cold prices works in fire-and-forget way. Meaning that you simply call our endpoint and we return you the data, which is never stored afterwards.
Hot prices endpoint is different from the cold one in the way that all the requests you make has id's assigned and stored in our DB. And you can always fetch this prices (fetch them all of fetch by id). For example, you can create them on the server side and then retrieve on the client.
Cold validations are performed via price endpoint, end hot validation use prices CRUD endpoints. You can get more details below.
