# Chapter 4. Sequential API

# Overview

As described earlier, the lwIP sequential API provides a straightforward and easy-to-use method of interfacing to the stack. Unlike the raw API, which requires event-driven callbacks, an application can simply call the API functions as needed to perform stack operations such as sending data, receiving data, or manipulating packet buffers or connections. While the raw API may allow for more efficient operation, the sequential API typically allows for simpler application design.
