Which method does FHIR specify for exchanging data?

FHIR, or Fast Healthcare Interoperability Resources, specifies the use of a RESTful exchange method via HTTPS for the exchange of healthcare data. This approach takes advantage of the widely used web technologies and protocols, allowing for a more flexible and efficient exchange of health information.

The RESTful architecture is designed for simplicity and allows for a clear and standardized way to access resources, making it easier for different systems to communicate. By utilizing HTTPS, FHIR ensures that the data exchange is secure, protecting sensitive health information during transmission. This modern approach facilitates real-time data sharing and is well-suited for web applications, which is essential in healthcare settings where timely access to information is crucial for patient care.

In contrast, other methods like SOAP (a protocol that relies on XML) and direct file transfers do not align with the FHIR specification for interoperability and clarity of communication. While XML data synchronization plays an important role in interoperability, it does not represent the core methodology that FHIR employs for exchanging resources, which is centered around RESTful practices.
