I am not developing anything on FusionFabric.cloud, so why it is called an app?
On FusionCreator, an application is the custom collection of APIs, SPIs or Datasets that you register through the Application Wizard.
By registering a FusionCreator application, a 2-minutes process, you get access to API, SPIs, or Datasets exposed on the platform and these APIs have endpoints connected to Finastra core systems.
Once the application is registered with the selected APIs, you are ready to make calls using the Sandbox tenant on FusionFabric.cloud. You are provided with Postman collections to get started and generate secret keys for API calls.
Check out the Get Started guide for a hands-on introduction.
