Third Party Provider (TPP) Services

What is a Third Party Provider and how does it impact you?

Changes introduced under the Payment Services Directive 2 (PSD2) offer you greater control over your data, giving you the option to securely share your online payment account information and make payments directly from your payment accounts by using authorised Third Party Providers (TPP). This is known as Open Banking.

It is important to know that if you do not want to avail of these TPP services, you do not have to. You are always in control. PTSB will never share your information with a TPP unless we have your authorisation.

There are three types of Third Party Provider services that you can avail of:

  • Account Information Services Providers (AISP):  AISP’s can request access to your accounts to view balances, transactions, statements, direct debits etc.
  • Payment Initiation Services (PISP): PISP’s can make payments on your behalf, transfer money between accounts, to other accounts, set-up standing orders and make international payments etc.
  • Card Based Payment Instrument Issuer (CBPII): A CBPII can make an enquiry to PTSB to see if you have sufficient funds in your payment account. They will not be given a balance of your account but just a ‘Yes’ for funds available or a ‘No’ for funds not available.

For full definitions of the above Third Party Providers and payment accounts, please see our General Terms and Conditions.

Authorising Third Party Provider services

When completing a transaction with your Third Party Provider, for security reasons, we may ask you to authorise the request and complete authentication.

This can be done in two ways:

  • The PTSB banking app (personal customers) or
  • Open24 web (business and personal customers)

Which authentication method is applicable to me?

PTSB app authentication

  • I am a personal customer and am using the latest version of the PTSB app on this device

Open24 web authentication

  • I am a business customer
  • I am a personal customer who does not use the PTSB app

You will continue to authenticate on the existing Open24 Web authentication.

I have PTSB App installed on my registered device but it’s not an up-to-date version, how do I authenticate Third Party Provider requests?

You will continue to authenticate on the existing Open24 Web Authentication

  • You will identify yourself with your Open24/Business24 number, Password and Personal Access Number.
  • You will then receive a Push Notification to your registered device and will need to enter 3 digits from your 6 digit Open24/Business24 Personal Access Number (PAN)  
How do I know if I have an up-to-date version of the PTSB App?

The PTSB App authentication for Third Party Provider requests will be available in version 6.2 or later. To check which version you have installed on your device follow the steps below 

  • Launch PTSB App on your device
  • Select menu button on top left hand (Three lines symbol)
  • Scroll to the bottom of the screen and you will see the version of the PTSB App displayed
How do I get the most up-to-date PTSB App on my device?

You will need to download the new version of the PTSB App to your registered device through the Google play store or Apple app store.

I have the PTSB App installed, why am I not being asked to authenticate on my app?

That could be for one of the following reasons:

  • The device you are using to interact with a Third Party Provider is not your registered device
  • The device you are using to interact with a Third Party Provider does not have the most up to date version of the PTSB App
  • You are interacting with a Third Party Provider on a laptop or personal computer
I am a Business Banking customer, can I use the Business24 authenticator app to complete my Third Party Provider requests?

No, you will continue to authenticate in the existing secure way via Open24 Web Authentication. 

What do I enter on the Welcome screen if I am both a Personal customer and a Business Banking customer?

If you are giving permission to the Third Party Provider to view data from your personal accounts, then select the Open24 option.  If you are giving permission to the Third Party Provider to view data from your non personal accounts, then select the Business 24 option.

What if I enter the wrong option on the Welcome screen?

Your Open24 online card number will be displayed on the screen. If you select the incorrect option you can cancel out of the journey at any stage. However, once you are advised that you are being redirected back to the Third Party Provider, you cannot cancel at that stage. You can attempt to complete the TPP transaction again and select the appropriate option.
