V3.0
/ec-datahub-svc/rest/v3.0/tenant/{tenantId}/studies/{studyId}/codelists
Retrieves the study-permissioned Study Level Codelists dataset for a single study and mode.
The dataset exposes versioned codelist configuration used in study design, including study, visit, form, and item context together with codelist definitions, localized code values, display metadata, grouping metadata, and audit columns.
Supports select, filter, sort, limit, and offset query patterns.
The dataset returns rows for codelists defined at study, event, form, and item level for the study versions available in the selected mode.
This version additionally includes the following data points: SITE_ASSOCIATION and CODELIST_MODE.
Required permission: StudyCodelistDatasetPost.
Recommended order columns: The backend query always orders results by DH_TIMESTAMP and VERSION_START in ascending order first. If orderColumns is empty, only these two columns are used. If orderColumns is provided, the specified columns are appended after DH_TIMESTAMP and VERSION_START. For stable, deterministic pagination, use STUDY_ID, CODE_LEVEL, STUDY_VERSION, EVENT_ID, FORM_ID, ITEM_ID, CODE_ID, CODE_VALUE_ID, LOCALE, and CODELIST_MODE in the orderColumns field of the request payload.
Request
-
studyId(required): string(uuid)
Unique study identifier supplied in the
studyIdpath parameter.Use the uppercase hexadecimal UUID value for the study.
Example:
0C7CBA3F70034C47947E2FAB086BFBF5. -
tenantId(required): string(uuid)
Unique tenant identifier supplied in the
tenantIdpath parameter.Use the uppercase hexadecimal UUID value for the tenant.
Example:
EC942244BB30163BE053BEC44C64CF34.
-
limit: integer(int32)
Minimum Value:
0Page size for the result set.
0disables pagination and returns the maximum result set allowed by the dataset endpoint.- Positive values enable pagination.
- Negative values return HTTP 400.
Example:100 -
offset: integer(int32)
Minimum Value:
0Zero-based row offset.
- Counts rows, not pages.
- To fetch the next page, repeat the same request body and set
offset = previous offset + previous count. - When
limit = 0, this value is ignored and the response echoesoffset = 0. - When
limit > 0, an offset beyond the available rows returns HTTP 200 with an empty page. - Negative values return HTTP 400.
