- Learn about the Foreign Exchange (FX) rates prior to a transaction being performed.
- Retrieve details of the exchange rate applied to a transaction, after it is authorised by the card processor and the ledger.
Pre-Transaction | Exchange Rates API
Before a transaction is processed, you can send requests to the Exchange Rates API and perform the following operations:Post-Transaction | Transaction Event Webhook
Once a transaction is authorised or declined, asynchronous webhook notifications are sent to the ledger including thetransaction.exchangeRates object — this comprises the ECB exchange rate applicable at the time of the transaction (provided only when the cardholder’s currency is different from the merchant’s currency).
Issuer’s Responsibility
As per the European Banking Federation (EBF) published implementation guidance: “Whilst the electronic message needs only to be sent after the first ‘in-scope’ payment order made using the card (and not for every subsequent ‘in-scope’ payment order), it must also be sent once every month in which the issuing bank receives from the payer a payment order denominated in the same currency.” Hence, a cardholder must at least receive one message per month for each currency pair. This is the minimum requirement for post-transaction disclosure. Example: A cardholder is based in the EU:- The cardholder performs 10 transactions in Swedish Krona (SEK) between 1st and 5th January: Send one notification after the first authorisation informing the markup for the SEK > EUR exchange rate.
- The cardholder performs 5 transactions in United States Dollars (USD) on 8th and 9th January: No notification is required, as this is not covered in the EBF implementation guidance.
- The cardholder performs 1 transaction in the currency of Poland (PLN) on 31st January: Send one notification after the authorisation informing the markup for the PLN > EUR exchange rate.
