1. Introduction

Single domestic payment allows the User/Customer to post his/her consent to the PISPs to make a one-time payment for a specific amount to a specific payee immediately, wherein the PISP provides this instruction to the customer’s ASPSPs. This use case details out the customer experience guidelines and technical API specifications that are required to be developed and followed by both ASPSPs and PISPs. This use case is applicable to both retail and corporate customers. Depending on few decision points (as explained in the End to End user flow), three variations of the user journey has been mapped and explained in detail in the section below.

Few sample domestic payments may include account to account transfers, loan re-payment, university/exam fee payments, merchant payments (including bill payments for electricity, water, telephone, cab, and ticket), credit card payments, restaurant/hotel payments, E-commerce payment, wallet payments, Invoice and other corporate payments.

This section describes how each of the Participants (PISPs and ASPSPs) involved in the delivery of these services can optimise the customer experience for these services. Furthermore, it provides clarifications to participants on the usage of the APIs, and best practice guidelines for implementation of the customer journeys.

2. Customer Experience Guidelines

2.1 Single Domestic Payments – A/C Selection @PISP

2.1.1 Customer Experience Journey

User/Customers can initiate, by providing their consent to PISPs, an instruction to their ASPSPs to make a onetime payment for a specific amount to a specific payee where all information for a complete payment order (including the User/Customers’ account details) is passed from PISPs to ASPSPs. Once User/Customers have been authenticated in ASPSPs domain, User/Customers must be directed back to the PISP domain.

Participant

Implementation Requirements

1

Minimum Set of Parameters

PISPs must either allow User/Customers to specify the below minimum set of parameters or pre-populate them for the User/Customers:

Payment Amount and Currency (BHD for Bahrain implementations)
Payee Account Name
Payee Account Identification details (e.g. IBAN, PAN)
Payment Reference (optional)

PISP

Required

2

User/Customer payment Account Selection

PISPs must provide User/Customers at least one of the following options:

Enter their Payer's payment Account Identification details
Select their Account Identification details (this assumes they have been saved previously and a user/customer is required to verify/authorize the account identification details in a PISP before storing it in PISP)

PISP

Required

3

User/Customer Consent to PISP

PISPs must request for the User/Customers' consent to the payment in a clear and specific manner. PISPs must display the following information in the consent screen:

Payment Amount and Currency (BHD for Bahrain implementations)
Payee Account Name
Payment Reference, if it has been entered by User/Customers or prepopulated by PISPs in item #1
User/Customer payment Account Identification

o Note 1: if User/Customer payment Account identification is selected in item #2, PISPs should mask the User/Customer payment Account details on the consent screen. Otherwise, or if the User/Customer payment Account identification has been input by User/Customers in item #2, PISPs should not mask these details to allow User/Customers to check and verify correctness

o Note 2: if User/Customer payment Account identification is provided by User/Customers in item #2, PISPs may use this to identify and display the ASPSP without having to ask User/Customer

For Payee Account Identification details (e.g. IBAN, PAN):

If this has been provided by User/Customers in item #1, then PISPs must also display this in the consent screen to allow User/Customers to check and verify correctness
If this has been pre-populated by PISPs (e.g. in an e-commerce payment scenario) PISPs may choose whether to display this information or not
PISPs must provide messaging to inform User/Customers that they will be taken to their ASPSPs to complete the payment. Example wording: "You will be securely transferred to your ASPSP to authenticate and make the payment"

PISP

Required

4

CX consideration:

Generic PISP to ASPSP redirection screen and message

SCA-Strong Customer Authentication

SCA must be the only action required at the ASPSPs (unless supplementary information required)

The ASPSP authentication must have no more than the number of steps that the User/Customer would experience when directly accessing the ASPSP channel

CX consideration:

If SCA as described in this section cannot occur on the same screen as displaying the amount and the payee (e.g. for some biometric authentications methods), then ASPSPs should offer User/Customers options to proceed or cancel the payment with "equal prominence”

ASPSP

Required

5

ASPSPs must display as minimum as the Payment Amount, Currency and the Payee Account Name to make the User/Customer aware of these details (unless an SCA exemption is being applied). These details must be displayed as part of the authentication journey on at least one of the following screens without introducing additional confirmation screens (unless supplementary information is required)

ASPSPs’ Authentication screen
ASPSP to PISP redirection screen

Note: Displaying the balance in this instance need not require any additional strong customer authentication

CX consideration:

ASPSPs should inform User/Customers about their “point of no return” for making the payment and that their payment will be made after authentication occurs. Example wording: “Authenticate to make payment”
Generic ASPSP to PISP redirection screen and message

ASPSP

Required

6

PISP Confirmation

PISPs must display the information received from the ASPSP. This information may include:

The unique identifier assigned to the payment instruction by ASPSPs

The payment status (and status update date & time) - Confirmation of successful payment initiation

If received from ASPSP, PISPs must display the following additional information:

The expected payment execution date & time

The expected settlement date & time (i.e. the value date of the payment)

The ASPSP charges (where applicable)

In case of payment cancellation,

PISP may update the User/Customer with reason for payment cancellation. The payment cancellation might be due to technical or non-technical scenarios. The messaging format for technical scenario may be simplified to make it easy for User/Customer to understand. Non-technical reasons such as fund availability, incorrect payee information, etc. may be detailed out.

CX consideration:

If User/Customers provide their payment account identification details (as per item #2 options), the PISP may, with the consent of the User/Customer, save the account details for future transactions (such as making further payments or initiating refunds back to User/Customers) where this is part of the payment initiation service explicitly requested by the User/Customer. For example, a merchant, upon request from the User/Customer, may initiate a refund back to the User/Customer, by instructing the same PISP that initiated the initial User/Customer transaction to use the saved User/Customer payment account identification details as the beneficiary details for the refund. This will be dependent on the same PISP being used by both the User/Customer and the merchant, their specific contractual terms and the existing regulations

Further Payment Status Update

PISPs must follow up with ASPSPs in order to check and update the User/Customers with the most updated information that can be received by ASPSPs in relation to the execution of the payment

2.2 Single Domestic Payments – A/C Selection @ASPSP

2.2.1 Customer Experience Journey

There may be cases where the payment order submitted by PISPs to ASPSPs is incomplete, such as where User/Customer account selection has not yet occurred. In these scenarios, Open banking guideline considers that SCA only needs to be obtained once, as part of the initial interaction between the ASPSP and User/Customer. The fact that the User/Customer has to then carry out account selection or provide other information does not invalidate the SCA just performed by the ASPSP.

Equally, the display of the account balance by the ASPSP as part of the account selection process in the payment initiation journey should not require an additional application of SCA.

2.3 Single Domestic Payments – A/C Selection @PISP / ASPSP (Supplementary Information)

2.3.1 Customer Experience Journey

In some scenarios, an additional step in ASPSPs' journeys may be required to display supplementary information to User/Customers. ASPSPs should determine the situations where this supplementary information is required, having regard to the principle that parity should be maintained between Open Banking journeys and ASPSPs’ online channel journeys, such that if supplementary information is not provided within the ASPSPs' online channels directly to User/Customers, then it must not be provided during an Open Banking PIS journey. ASPSPs should also ensure that this information does not constitute an obstacle or additional check on the consent provided by the User/Customer to the PISP.

Note: The user/customer journey shown below is for a/c selection @PISP and similar variation will also apply in the a/c selection @ASPSP.

ASPSPs must determine the situations where Supplementary Information is required to be shown to the User/Customer, having regard to the principle that parity should be maintained between Open Banking journeys and ASPSP direct online channel journeys. Supplementary Information may be required (illustrative):

Where fees, charges or Forex apply
Where interest rates apply
To display a User/Customer warning that the relevant payment account will become overdrawn/exceed an overdraft limit as a result of the intended payment
If the relevant payment submission cut-off time has elapsed and the ASPSP wishes to offer an execution date/time
Where the User/Customer has been identified by the ASPSPs as a vulnerable customer (who therefore receives tailored journeys and messages in ASPSP’s own online platforms)
To show value-add information based on functionality implemented by ASPSPs in competitive space which provides positive customer outcome (e.g. cash flow prediction engine)
For high value transactions using a different payment scheme
Where the payments may be duplicated by the customer in a short period (e.g. ASPSP may display a warning that payment appears to be duplicated)
