Data Manipulation - Introduction

Data manipulation is a core aspect of applications, especially business process automation and integration with external systems. Liferay’s headless APIs provide a secure and reliable way to create, update, and delete data. This API-driven approach safeguards against the risks of direct database alteration, ensuring system integrity.

So far, you’ve explored strategies for retrieving data efficiently using REST and GraphQL APIs. In this module, you’ll explore key techniques for manipulating Liferay data effectively, whether you’re handling individual records, attachments, or bulk datasets.

By the end of this module, you’ll have the skills to

• Create, update, and delete records with REST and GraphQL APIs.
• Optimize API attachment handling with Base64 encoding or external URLs.
• Conduct bulk imports and exports with batch APIs.
