Business requirements are built and delivered independently on a scalable, secured, and  industry-based, standard IBM Cloud platform.  To deliver engaging customer experiences, the business team needs to provide APIs that  combine data from multiple sources. They want to explore ideas for these new APIs without  the cost and time implications of a full IT project. They do this by using integration specialists’  APIs that already exist for the data that they need. This section shows how IBM App Connect  Designer enables non-integration specialists to implement hybrid APIs that are based on a  composite of existing on-premises and SaaS-based APIs.  The business team are exploring new innovative API possibilities that would combine existing  APIs with data from the SaaS applications they use. They want to be able to prototype these  without the need for an integration specialist from the central team. Using IBM App Connect Designer, you can easily create cloud managed APIs that enable  you to call out to an on-premises API, and aggregate data between enterprise systems and  SaaS applications. We will continue to use the store warehouse for our business scenario. Currently, the store  has its stock inventory and CRM systems on-premises, exposing the data via API. They have  recently adopted ServiceNow SaaS for incident management to improve customer  experience. ServiceNow is a cloud-based platform that supports service management for all  departments of your business including IT, human resources, facilities, field service, and  more. The business team would like to automate the initiation of incident tracking in ServiceNow  whenever a stock product is under recall due to a fault. By utilizing an existing on premises  API that provides a customer list with the product installed, the business team will aggregate  the data using an IBM App Connect Designer API flow to generate new incidents into its  ServiceNow application. This hybrid composition will be exposed as an API such that it can  be initiated by other applications.
