Get UniversalTrackerValue History

Retrieve the complete history of changes for a universal tracker value.

GET /v1/universal-tracker-values/:utrvId/history

The history endpoint returns all historical changes made to a UTRV, sorted by date (most recent first). Each history entry includes the action type, timestamp, value at that point, and any associated notes or evidence.

Response structure:


interface HistoryResponse {
  universalTracker: {
    _id: string;
    name: string;
    valueLabel: string;
    type: string;
    valueType: UtrValueType;
    unit?: string;
    unitType?: string;
    numberScale?: string;
    instructions?: string;
  };
 
  history: {
    _id: string;
    action: 'created' | 'updated' | 'verified' | 'rejected';
    date: string; // ISO 8601 timestamp
    userId: string; // Resolve user details from users array
 
    // Value fields (for number/percentage types)
    value?: number;
    unit?: string;
    numberScale?: string;
 
    // Complex value data (for text/table/list types)
    valueData?: {
      data?: string | string[] | Record<string, string | number>;
      table?: { code: string; value: string | number }[][];
      notApplicableType?: 'na' | 'nr';
    };
 
    valueType?: UtrValueType;
    note?: string;
    assuranceStatus?: 'created' | 'completed' | 'completed_open' | 'rejected' | 'restated' | 'partial';
 
    // Evidence references - resolve full details from documents array
    evidenceData?: {
      documentId: string;
      description?: string;
    }[];
  }[];
 
  // Lookup arrays to resolve IDs from history entries
  users: {
    _id: string;
    firstName?: string;
    surname?: string;
  }[];
 
  documents: {
    _id: string;
    type: 'link' | 'file';
    url: string; // For links: the actual URL, for files: signed download URL (~1 hour expiry)
    name?: string;
    description?: string;
  }[];
}

Response Structure: The response is optimized to avoid data repetition by separating users and documents into lookup arrays:

history[].userId → Resolve user details from users[] array by matching _id
history[].evidenceData[].documentId → Resolve full document details from documents[] array by matching _id

Important Notes:

The evidenceData field includes a document ID and optional description.
Document URLs have different meanings:
- Link documents: User-provided URL (not validated)
- File documents: Signed download URL with temporary access (~1 hour expiry)

Use Cases:

Audit trail for data changes
Tracking data revisions over time
Understanding data verification workflow
Compliance and assurance reporting
Resolving who made changes (via userId → users lookup)
Accessing evidence documents (via evidence IDs → documents lookup)
