Introduction to Open Banking Account Information

Temenos Transact Account Access APIs help customers to access their account details through any authorised Third Party Provider (TPP) interface that connects to the bank. These APIs are based on the UK OBIE (Open Banking Implementation Entity) standards as defined as part of the PSD2 (Revised Payment Service Directive).

A TPP that facilitates enquires on an account is denoted AISP (Account Information Service Provider). The bank that owns the account details and shares the information through the TPP is denoted ASPSP (Account Servicing Payment Service Provider). The customer who uses the TPP is denoted PSU (Payment Services User).

A customer (PSU) is required to create a consent in order to access his or her account details through a TPP.

When a customer invokes any one of the account related enquiries through the TPP, the account number that comes in the request is checked against the list of authorised accounts stored at the consent level. The TPP Reference, Customer ID, Consent Type and Expiry Date are also checked simultaneously.

The following API’s are delivered for getting the account access consent:

Consent API	API Description
Create Consent	Create Consent with the above-mentioned details.
Get Consent Status	Provide the status of the consent The consent is considered to be Authorized (Live) if the arrangement Status is AUTH and the Expiry Date is less than or equal to Current Date.
Delete Consent	Delete a consent or close a consent arrangement before its expiry date

If the account is available in the list, Temenos Transact sends the requested information for that account in the response. If the consent is not available or has expired, then Temenos Transact will not process the request.
