DownloadReturns the account-details and associated balance(s) for a given payment account that is specified by the AISP through an encrypted logical-id of the account. In case of a multi-currency account, the returned account balance is always a balance in euro. This balance is associated with the balance of the euro compartment or the globalised amount in euro of the balance of all compartments (depending on the parameter of the account). A list of each currency compartment with its balance is also provided in the API response.
Encrypted Logical ID of the account which is mapped to IBAN.

Returns the booked transactions for a given payment account that is specified by the AISP through an encrypted logical-id for the account. The request may use some filter parameter in order to restrict the query, e.g. the attributes "date_from" and "date_to". The result may be subject to pagination (i.e. retrieving a partial result in case of having too many results) through a set of pages by the ASPSP. Thereafter, the AISP may ask for the next page of results.
Encrypted Logical ID of the account which is mapped to IBAN.

Conditional: SCA token to be passed as header. It is mandatory to be able to access the transactions older than 90 days from today [date_from < today - 90 days]. The SCA-token can be retrieved immediately after the account(s) enrolment or by using a separate SCA flow (please refer to the "flow" section for more information). The token itself is an encrypted JWT valid for 1 hour. Plese note that the SCA-token will be checked only if date_from is filled & meets the criteria of date_from < today - 90 days.
