Why am I only able to see 90 days worth of data on first link?
As part of the Regulatory Technical Standards required by some institutions in Open Banking connections, SCA (Strong Customer Authentication) may impose different requirements specific to each individual bank connection. One goal of SCA is to limit the retrieval of sensitive or historical transaction data to a set period of time after the initial consent and authentication of an end-user.
This means that depending on the bank, clients may only be allowed to access as much transactional data allowed by the bank for a period of 5 minutes after the initial authentication by the end-user. After this period, banks who enforce SCA will only return 90 days of transaction data.
In layman terms, Codat will retrieve as much data as possible following authentication by your end-user. However, regulatory standards may limit the amount of data initially retrieved to 90 days.
