What is a flow in MuleSoft?

A flow in MuleSoft is fundamentally a series of message processors that define the sequence of actions that are executed within an application. This structured sequence allows developers to outline how data is processed as it moves from one component to another—essentially orchestrating the interactions between various systems and services.

In a flow, each message processor can perform different tasks such as transforming data, routing messages, making HTTP requests, calling APIs, and handling exceptions. The design of a flow allows developers to visually connect these processors, making it easier to understand and maintain the application's logic. Flows are core to building any integration in MuleSoft, enabling the automation of processes and ensuring that data is handled correctly at each step.

This understanding of flows is crucial for developing effective integration solutions as it emphasizes the sequence and logic applied to the data throughout its lifecycle in the application.
