Why use bank board rates through an API?

The Narodowy Bank Polski official rate is what accounting, tax and customs rules name, but it is not what a customer pays at the counter or in an app. Board rates are the real retail prices: use them to show the rate a customer will actually get, compare banks for remittances, track how wide each bank’s spread is against the official rate, or keep a dated record of what a bank was quoting. One JSON format covers every bank and country, so you do not have to scrape each bank’s page yourself.

Frequently asked questions

Is the Erste Bank Polska (formerly Santander Bank Polska) rate the official Poland exchange rate?

No. Erste Bank Polska (formerly Santander Bank Polska) sets its own buying and selling rates and changes them through the day. The official rate is published once per business day by the Narodowy Bank Polski; it is shown in the Official column and is the figure accounting, tax and customs rules refer to.

Which Erste Bank Polska (formerly Santander Bank Polska) rate applies when I send money abroad?

The sell rate: you are buying foreign currency from the bank. When you convert foreign currency into PLN, the buy rate applies. Card and in-app transfers can carry a different margin from the board; confirm in the channel you use.
