OMOPHub FHIR Terminology Service URL — omophub_fhir

Convenience helper for constructing the OMOPHub FHIR Terminology Service base URL for a given FHIR version. Use it when configuring an external FHIR client library (httr2, fhircrackr, etc.) to talk to OMOPHub's FHIR endpoint directly.

Usage

omophub_fhir_url(version = c("r4", "r4b", "r5", "r6"))

Arguments

version: FHIR version prefix. One of "r4" (default), "r4b", "r5", or "r6".

Value

A character scalar with the full FHIR base URL, e.g. "https://fhir.omophub.com/fhir/r4".

Examples

omophub_fhir_url()
#> [1] "https://fhir.omophub.com/fhir/r4"
omophub_fhir_url("r5")
#> [1] "https://fhir.omophub.com/fhir/r5"

if (FALSE) { # \dontrun{
# Use with httr2 to call the $lookup operation directly
library(httr2)
req <- request(omophub_fhir_url()) |>
  req_url_path_append("CodeSystem/$lookup") |>
  req_url_query(
    system = "http://snomed.info/sct",
    code = "44054006"
  ) |>
  req_headers(Authorization = paste("Bearer", Sys.getenv("OMOPHUB_API_KEY")))
resp <- req_perform(req)
} # }
