How do open bank payments work?

The principle of operation of open banking providers see here and know that it is based on cooperation between banks and third parties. Banks provide third-party companies with access to certain banking data and the ability to make payments on behalf of customers through specially designed APIs. This allows third-party services to create innovative financial products and services such as personal financial planning, automatic insurance rate comparison, investment portfolios, financial management, and more.
Customers can access their banking data and make payments through a single platform of third-party services, without having to switch between different banking applications.
