V10.0
/ec-datahub-svc/rest/v10.0/tenant/{tenantId}/studies/{studyId}/{mode}/subjects/blindedVisits
Retrieves the study-permissioned Blinded Subject Event dataset for a single study and mode.
The dataset exposes blinded subject visit history, including site, subject, visit scheduling and status, transfer context, form completion counts, and audit columns, without exposing unblinded treatment assignment details.
Supports select, filter, sort, limit, and offset query patterns.
The dataset returns versioned subject-visit rows for subjects associated with the study and mode.
This version additionally includes the following data points: LOCKED.
Required permission: BlindedSubjectEventDatasetPost.
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, SUBJECT_ID, EVENT_ID, EVENT_INSTANCE_NUM, and KIT_NUMBERS in the orderColumns field of the request payload.

limit: integer(int32)
Minimum Value:
