Types of flow in IBM App Connect
You can create two types of flow in IBM App Connect: an event-driven flow and a flow for an API.
A flow for an API contains a request, one or more target application actions, and a response. The request uses a model that you define to request the creation, replacement, or retrieval of data objects in your applications. When the request is submitted, each target application performs its action. The flow then returns a response that either confirms that the actions were successful, or returns the data that was requested.
In an event-driven flow, you identify an event that can occur in your first application (the source application), and actions that can be performed in one or more target applications. The flow links the event to the actions so that, whenever the event occurs in the source application, the action is automatically triggered in the target applications. Each successfully completed action counts towards your monthly quota. When you create a flow, you add your applications, and choose actions. Then, you map the data that you want to transfer between your applications.
