Prerequisites

WSO2 Open Banking Accelerator is a collection of technologies that increases the speed and reduces the complexity of adopting open banking compliance. Instead of building an open banking solution from scratch, you can use WSO2 Open Banking Accelerator to meet all open banking requirements with additional benefits beyond compliance. You can use the WSO2 Open Banking Accelerator on top of the following WSO2 products.

You can use any of the following base products:

  • WSO2 Identity Server - 7.2.0, 7.1.0, 7.0.0
  • WSO2 API Manager - 4.6.0, 4.5.0, 4.4.0, 4.3.0

The accelerator mainly addresses the open banking requirements such as API consumer application onboarding, consent management, and access authorization among numerous other features to set up an open banking solution. You can easily implement a toolkit to customize the accelerator and help you comply with any regional open banking requirements. For more information on customization, see the Develop section.

Note

In a standalone setup, these products are deployed in a single server. However, in a typical production environment, it is recommended to deploy the components in separate servers (distributed) for better performance.
