This document describes the updates to our APIs to address the potential issue of rate changes between fetching a rate/quote and initiating a transfer or currency swap. We have implemented the use of a quoteID to lock rates for a specified duration within which the locked rates can be used.
We have introduced a new field expiration_date to the payload for creating bank accounts (only EUR and GBP). This change is part of our ongoing efforts to enhance the security and functionality of our banking API.
