MuleSoft Catalyst is an IT operating model developed by MuleSoft to enable customers to adopt API-led connectivity. The critical components of MuleSoft Catalyst include Catalyst Knowledge Hub, Catalyst Mobilize, and Catalyst Accelerators. ‘Accelerator for Banking’ is a set of pre-built API designs and implementations to jumpstart the development of typical use cases in banking applications. We will discuss the integral components of the MuleSoft Catalyst operating model and its recommended adoption methodologies during this meetup session. In addition, we will be extrapolating a case study on Open Banking Platform Strategy and how a market leader in the financial services industry has adopted the MuleSoft Catalyst to transform itself into an open banking-as-a-service platform.
