# Update records (fails if not found)

Update existing records only

            Only updates existing records. Returns error if record not found by systemRef.
            The systemRef field is required for all records in PUT requests.

            Partial Success Behavior:
            - Each record is processed independently
            - Successful records are persisted even if others fail
            - Records not found will have status FAILED with error code RECORD_NOT_FOUND
            - Check summary.failed and individual records[].status for failures

            Limits: Maximum 100 records per request.

Business Applications:
- Strict update workflows
- Guaranteed existence updates

curl --location 'https://{{host}}/api/v1/records' \
