We're finally done with this module. In general, there are infinite approaches to writing code. In this chapter, I used an approach that I think is easy to understand. Feel free to be different and code the way you like. This book is not intended to teach you coding, but to teach you Phalcon. You might have noticed that for an API, we don't use any validations. You can practice a little and connect your forms to the API.

In the next chapter, we will switch to the Frontend module, where we will make some small modifications to the API. We will also try to implement a search engine based on Elasticsearch (https://www.elastic.co/products/elasticsearch).
