Open Banking Accelerator

Capabilities of the accelerator


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 a solution from scratch, you can use WSO2 Open Banking Accelerator to meet all legislative requirements with additional benefits beyond compliance. The accelerator runs on top of WSO2 Identity Server and WSO2 API Manager.

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 standard.


Open banking provides a great opportunity for financial institutions to reinvent their legacy systems using fast-developing technologies. WSO2 Open Banking Accelerator delivers comprehensive technology and strategic consultancy to help you execute standards-compliant, commercially successful open banking initiatives.
