How it works

Our Open Banking APIs for Account Information Services (AIS) provide the ability to extract individual or company transaction and balance data from multiple accounts. Payment Initiation Services (PIS) enable customers to make online purchases. Cashflow Analyser is an online tool that provides immediate insight into customers' cash flow.

With YTS, business can outsource the challenge of building and maintaining bank API connections and also take care of the need to be licenced, since it is a licenced provider.

2016 - 2019

Do you have redundancy and coverage provided by multiple integrations (APIs & Direct Access)?

No, we provide only the PSD2 PIS API

How will you handle automated refunds?

Automated Refunds can be achieved by configuring the PIS API in such a way that the initial PIS payment is reversed. 

How will you mitigate the risk of bank transactions failing?

There is no mitigation of failing bank transactions. The PIS payment is executed instantly, and we will inform our client of a successful PIS payment.
In Q3 2021 we will also offer future dated and recurring PIS payments with a risk of a lack of balance. This risk is for the client.

How will you reconcile payments efficiently?

We do not support payments reconciliation
