MyBank is built on the 4-corner model, involving Payers, Payees, Payer PSPs, and Payee PSPs.


Distributed Connection


The Merchant conveys the e-authorization requests through the Routing Service owned and provided by a Seller Bank

The request is received by the Payer PSP’s Validation Service and presented to the Payer through the Home Banking environment.


Payer PSPs

Payer PSPs enable customers to make online payments with MyBank. A Payment Service Provider on the payer side will have a Validation Service to handle transaction requests from the Payee’s Payment Service Provider and to communicate with its online/mobile banking environment. 


Payee PSPs

Payee PSPs enable merchants to collect payments with MyBank. A Payment Service Provider on the payee side will receive the initiating party request from the merchant and forward it via its Routing Service to to the Validation Service of Payer PSPs.


Gateway Connection

MyBank Gateway is the new solution to connect to MyBank.

It is a technical service owned and managed by MyBank Solution Manager, allowing Payee PSPs to exchange technical messages with Payer PSPs.

PSPs communicate only with MyBank Gateway through an API-based direct connection.  A single SCT credit instruction is generated by the Payer PSP for each transaction. Payee PSPs will receive SCT payments and credit the funds to their Sellers’ accounts.

PRETA S.A.S. provides technical specifications, legal documents, as well as a platform to carry out testing activities.


The main advantages of this solution are:

- Direct connection through APIs specifically designed for Payer PSPs and Payee PSPs

- Seamless integration via a REST API to initiate transactions and retrieve their status

- Dedicated MyBank Gateway User Interface to monitor transaction status

- Reduced ICT development and maintenance

- New use cases (e.g. MyBank QR code) with a quick time to market

- Direct Support from PRETA
