Keywords: Liferay Objects, Liferay 7.4, Liferay tutorial, Liferay API, Liferay development, low code platform
🚀 Introduction
If you have worked with Liferay earlier, you probably remember the pain of Service Builder—writing XML, generating code, deploying modules, and managing OSGi.
In my experience working on Liferay-based portals, even a simple CRUD feature used to take hours or sometimes days.
But with Liferay 7.4, everything changed.
Liferay Objects is a powerful low-code feature that allows you to create database entities, APIs, and UI directly from the browser—without writing backend code.
---📌 What are Liferay Objects?
Liferay Objects allow you to build applications directly from the Control Panel UI.
- Create database tables
- Define relationships
- Configure UI layouts
- Automatically generate REST APIs
Once published, Liferay automatically creates:
- Headless REST APIs (
/o/c/{objectName}) - GraphQL APIs
- Permission management
- UI interfaces
💡 Real Insight: I used Liferay Objects to quickly build an internal ticket system, and it reduced development time by almost 70%.
---⚖️ Service Builder vs Liferay Objects
| Feature | Service Builder | Liferay Objects |
|---|---|---|
| Development Speed | Slow | Fast |
| Deployment | Manual | Instant |
| API Creation | Manual | Automatic |
| Best Use | Complex logic | CRUD apps |
🛠️ Step-by-Step: Build a Support Ticket System
Step 1: Create Object
- Go to Control Panel → Objects

Step 3: Add Relationship
Create relationship with User (One-to-Many)
---Step 4: Configure Layout
Use drag-and-drop builder to organize fields.
---Step 5: Publish
Click Publish → Your API is ready instantly.
http://localhost:8080/o/c/supporttickets
💡 Real Experience: First time I published an object and saw the API working instantly, it felt like skipping hours of backend work.
---⚡ Advanced Features
- Webhooks: Send data to external systems
- Actions: Trigger workflows
- Validations: Enforce rules
💡 Pro Tips
- Always finalize field types before publishing
- Use Site scope for multi-tenant apps
- Export configurations for reuse
⚠️ Common Errors & Fixes
1. Cannot change field type
Fix: Create new field and migrate data
2. Object not visible
Fix: Configure Panel Link
3. 403 API Error
Fix: Assign permissions in Roles
---📊 Conclusion
Liferay Objects simplify development and reduce dependency on backend coding.
If you are starting a new Liferay project, this should be your default approach.
