FHIR has three main types of interactions.
- RESTful API A (FHIR) resource exchange framework. A set of core search parameters can be found on the resource profile pages (see Resource Index below)
- Command 'pagelink' could not render: Page not found.A messaging exchange framework. The FHIR equivalent of HL7v2 or traditional messaging
- Command 'pagelink' could not render: Page not found.A document based exchange framework. The FHIR equivalent of HL7v3 CDA (clinical document architecture)
Which interaction should be used and general interaction guidance can be found in Integration Patterns Book
