How does it work?

Explore our ready to configure, Software as a Service (SaaS) platform that connects PSPs and banks to Request to Pay.


A customer makes a purchase and wants to pay using Request to Pay.


The biller initiates a request for payment with their payment services provider.  The biller’s PSP uses SPX to route the request to the payer’s PSP.


Answer Pay’s SPX delivers the request for payment to the payer’s PSP who then notifies the payer.


The payer’s response is communicated to the biller via payment service providers.  PSP’s are interconnected with Answer Pay’s SPX.


The Payer’s PSP collects the money from their customer using whichever payment methods they support.  The PSP sends the money via bank transfer to the biller’s PSP.

Case study

graphic to show paying by request to pay

An Open Banking powered payments provider wanted to increase the engagement with their customer facing app. 

Struggling with a high rate of churn our client was excited by the opportunity to increase customer engagement in their app.  By embedding the receipt of payment requests, their customers would have an unavoidable need to come back time and again.  However building and maintaining Open Banking connectivity across Europe is complex and they did not want to distract from this core part of the service. So they chose to connect using Answer Pay’s SPX™ platform. 

Connecting to SPX™ allowed them to leverage our pre-certified platform and APIs to significantly reduce their time to market.  Plus as new parties join the Request to Pay ecosystem, SPX™ automatically makes them available reducing ongoing maintenance costs too.  The solution was fully white labelled and embedded in their existing application making it easy for customers to adopt.

They are now seeing their payments volume build and are gaining new customers.
