Suggested payer details - Subscriptions UX

To support merchants with strict account verification requirements, this enhancement ensures that payer details—such as PayID or BSB/Account—are securely prefilled and locked when creating a PaymentAgreementRequest via Subscriptions app.

In order to prefill BSB/account number or PayID field shown to your customer, simply send in a value in suggestedPayerDetails field. Please refer to this Payment AgreementRequest API file specification for further details.

Note: If you send in a value to suggestedPayerDetails, your customer will not be able to edit the PayID or BSB/Account number in this field when it is shown to them on the UI
