What technologies can Liferay integrate with for external systems?

Liferay is designed to be highly extensible, allowing integration with various external systems to enable seamless data exchange and functionality enhancement. The integration with external systems can effectively utilize protocols such as SOAP and REST, which are widely adopted for web services.

SOAP (Simple Object Access Protocol) provides a robust messaging framework for exchanging structured information in web services, allowing Liferay to communicate with other services that are SOAP-compliant. This is useful for enterprises that rely on established standards in their integrations.

REST (Representational State Transfer) is another core technology that Liferay supports, enabling the use of RESTful APIs for more lightweight interactions with web services. REST is particularly beneficial for modern web applications, allowing Liferay to interact with services that follow RESTful principles, utilizing standard HTTP methods to create, read, update, or delete resources efficiently.

Additionally, message queues allow for asynchronous communication between services, which is essential for managing complex workflows and ensuring that messages can be processed reliably, even in situations where systems are temporarily disconnected.

The other options listed involve important data formats (like XML and JSON) and communication protocols (like FTP and SMTP), but they do not represent the extent of integration technologies that Liferay specifically supports for external system interactions. GraphQL is another modern
