Data Retrieval - Introduction

Efficient data retrieval is the cornerstone of building dynamic applications with Liferay's headless APIs. Liferay offers powerful tools and flexible query strategies empowering you to shape and access data for any integration scenario.

In this module, you’ll explore the fundamentals of data retrieval using Liferay’s REST endpoints. You’ll learn how to leverage service parameters to refine queries, restrict payload size, and retrieve related data. Additionally, you’ll gain insight into Liferay’s search API, an advanced tool for executing robust and scalable queries.

By the end of this module, you’ll be able to

• Use GET methods to retrieve data.
• Optimize queries with service parameters like search, filter, and pagination.
• Leverage relationship endpoints and nested fields to query related data.
• Harness search and search suggestion APIs for advanced data retrieval needs.
