get/Observation

Query parameters

_idstring

The logical id of the resource to search for. Matched exactly and case-sensitively; it does not accept the system|value form. A resource belonging to another clinic returns no match rather than an error.

_lastUpdatedstring

Filter by last-updated time. Accepts the prefixes ge, gt, le and lt, or no prefix at all, which matches the whole period given. A bare date such as 2026-08-01 therefore covers that entire day.

_countinteger

Number of results per page. Defaults to 50 and is capped at 100: a larger value returns 100 rather than an error.

_sortstring

Comma-separated list of fields to sort by (prefix with '-' for descending).

patientstring
categorystring

e.g. survey.

codestring

LOINC code (e.g. 44249-1 for PHQ-9).

datestring

Response

A searchset Bundle of matching resources.
