Updating an Observation

To update an existing resource with a new value, use the PUT or PATCH endpoints. You can identify the resource by using the id returned during creation or by locating it via the search endpoint.

Search example

Here is an example utilizing the ACCESSION, MRN and CODE to search for an existing resource.

curl --request GET \
 --url '${BASE_URL}/fhir/R4/Observation?part-of%3Aidentifier=ACCESSION&subject%3Aidentifier=MRN&code=US_CAROTID_RT_INT_DISTAL_PSV' \
 --header 'Authorization: Bearer ${access_token}' \

PUT example

curl --request PUT \
  --url ${BASE_URL}/fhir/R4/Observation/111-1111-1111-1111-111111111111 \
  --header 'Authorization: Bearer ${access_token}' \
  --header 'Content-Type: application/fhir+json' \
  --data '{
