It's more of a subscription driven consumption based model, where the APIs are developed to connect backend ERP systems such as SAP and deployed into a library for consumption by both internal and external consumers. The APIs are exposed to the consumers that get onto the API gateway and identify the needed API from the library, use the instructions to subscribe, quickly test and connect to the backend SAP to get the expected information/transaction processed. Prior to this solution there was an age old EDI interface solution. This is enabling the customers to be more flexible with their integration architecture and be more agile as it reduces the IT integration dependency and provides a better user experience.
This is part of Techwave application modernization strategy to bring solutions that can bring agility and flexibility to customers and be able to decouple business with huge IT dependent solutions. This is helping us to help our customers migrate away from the age old EDI technology to the latest API and microservices based architectures.
