FHIR endpoints

FHIR servers are REST endpoints and use this sender. The FHIR Quickstart walks through configuring a Web Service Connection and a REST sender to submit FHIR resources end-to-end. Resources -> FHIR collects the URL anatomy, search syntax, Bundle types, and HL7 v2-to-FHIR field mappings you reach for while building those channels.
