Why this Post Matters
We want to communicate two important points:
- iDempiere’s REST API has become quite powerful and well documented over the last 2 years.
- It now includes a Swagger (OpenAPI) interface to help new developers get started.

What is a REST API?
REST (Representational State Transfer) API is a widely used architectural style for building web services that interact with data and applications over HTTP. A REST API allows clients to perform operations such as creating, reading, updating, and deleting (CRUD) resources using simple HTTP requests like POST, GET, PUT, and DELETE.
Why is REST API Important?
The importance of REST APIs lies in their ability to provide seamless communication between different applications, platforms, and systems. They enable:
- Interoperability: Different software applications can easily communicate with each other.
- Scalability: RESTful APIs are stateless, making them highly scalable.
- Simplicity: Using HTTP methods simplifies integration.
- Flexibility: REST APIs can be used across various programming languages and platforms.
- Security: Supporting industry proven standards like JWT, API Keys, OAuth, etc, REST APIs ensure secure access to resources.
How REST API Expands iDempiere as a Development Framework
iDempiere is an open-source ERP system that provides a strong foundation for business applications, but it is also a very capable and robust development framework. With the integration of REST APIs, iDempiere extends its capabilities beyond a traditional ERP, allowing developers to:
- Build Custom Applications: Leverage iDempiere’s backend capabilities in web and mobile applications.
- Automate Business Processes: Streamline workflows by integrating with third-party systems.
- Enhance Data Access: Enable external applications to retrieve and manipulate iDempiere data in real-time.
- Enable Microservices: Develop modular services that communicate with iDempiere via REST.
Exploring iDempiere Swagger for REST API
To simplify REST API usage, iDempiere provides a Swagger UI, an interactive documentation tool that helps developers explore, test, and integrate REST endpoints without manually writing requests. With iDempiere’s Swagger, you gain OpenAPI compatibility, allowing for standardized API documentation and seamless integration across various tools and platforms.
With iDempiere’s Swagger, you can:
- View all available REST endpoints.
- Understand request parameters and expected responses.
- Test API calls directly from the browser.
- Generate client-side code for integration.
Conclusion
REST APIs empower developers to extend and customize iDempiere in ways that were previously difficult or impossible. By leveraging the iDempiere REST API and its Swagger UI, businesses can create scalable, efficient, and flexible solutions tailored to their needs. Whether building a new application, automating workflows, or integrating third-party services, REST APIs make iDempiere a powerful development framework.

I am a systems engineer with a great passion for open source, software development, and technology in general. I have been part of the iDempiere community since 2012. I believe the enterprise world is one of the most aggressive environments out there. Companies tend to ruthlessly compete against each other. That is why seeing competitors co-exist and cooperate in harmony in iDempiere (and OSS communities in general) is so interesting to me.
