Data Access

Access to customer data can be obtained by sending requests to our interface Account Information Service (AIS) data endpoints. We provide support for accounts, balances, statements and transactions of the Open Banking Specification 3.1.2

All data endpoints are served over MTLS. Therefore, TPPs must present a valid OpenBanking transport certificate to successfully connect. Each request MUST also include an Authorization header containing the access token issued in response to the authorization_code grant for a given consent.

We do not currently provide pagination on any of the data endpoints. Our interface implements rate-limiting on TPP data requests. Where the customer is not present (as indicated by the absence of a x-fapi-customer-ip-address header) and the rate limit is reached, a 429 response will be returned.

Accounts

Our implementation supports individual and bulk Account requests.

Bulk Accounts Data

GET /accounts

Allows a TPP to enumerate the accounts for a given consent and obtain the details of those accounts.

The consent associated with the presented access token must have been created with either the ReadAccountsBasic or ReadAccountsDetails permissions.

The account details returned will depend on which permission was included in the original consent.

Transactions

Our implementation supports individual and bulk Transaction requests.

To use the transactions endpoint the associated consent needs to have either the ReadTransactionsBasic or ReadTransactionsDetail permissions.

You’ll only be able to fetch transactions that were made in the range defined by TransactionFromDateTime and TransactionToDateTime in your consent.

Responses from the transactions data endpoint do not include the FirstAvailableDateTime and LastAvailableDateTime Meta fields.

Transaction amounts can change after the transaction is first created, and you can use the Status field to help identify transactions that are still pending.

Bulk Transactions Data

GET /transactions

Retrieves transaction data for all accounts associated with the customer consent granted for the access token presented.
