OpenAPI specification for FHIR resources

Does FHIR publishes OpenAPI specification for FHIR resources?
I do not find the specification in the FHIR website.

There’s no openAPI document for the specification as a whole. There are openAPI documents in the implementation guides, one for each CapabilityStatement, though they are often not linked. The are always produced anyway. But there are problems with the openAPI documents:

  • tools vary in how they support the specification - particularly the json schema part
  • we only standardise some of the openAPI document.

Suggest you look at https://chat.fhir.org/#narrow/stream/179166-implementers/topic/fhir-codegen.20for.20OAS
