Archive NICE CXone Data Actions Partitioned Tables with TypeScript

What You Will Build

• A TypeScript module that programmatically archives partitioned table segments in NICE CXone Data Actions by constructing validated archive payloads, executing atomic deletion, and synchronizing with cold storage.
• Uses the CXone REST API with axios and strict TypeScript interfaces for schema validation, metrics tracking, and audit logging.
• Covers TypeScript/Node.js with production-grade error handling, retry logic, and webhook alignment.

Prerequisites

• OAuth 2.0 Client Credentials flow with scopes: datamgmt:read, datamgmt:write, webhooks:write, analytics:read
• CXone API v2 (Data Management & Webhooks)
• Node.js 18+, TypeScript 5+, axios, pino, uuid
• Access to a CXone organization with Data Actions and partitioned tables enabled
• Environment variables: CXONE_BASE_URL, CXONE_CLIENT_ID, CXONE_CLIENT_SECRET, CXONE_TABLE_ID

Authentication Setup

CXone uses a standard OAuth 2.0 client credentials flow. The token expires after 3600 seconds. Production code must cache the token and refresh it before expiry to prevent 401 cascades during batch archive operations.

import axios, { AxiosInstance } from 'axios';
import pino from 'pino';

const logger = pino({ level: 'info' });

interface CxoneToken {
  access_token: string;
  token_type: string;
  expires_in: number;
}

export class CxoneAuth {
  private client: AxiosInstance;
  private token: CxoneToken | null = null;
  private expiryTimer: NodeJS.Timeout | null = null;

  constructor(private baseUrl: string, private clientId: string, private clientSecret: string) {
    this.client = axios.create({ baseURL: this.baseUrl, timeout: 10000 });
  }

  async getAccessToken(): Promise<string> {
    if (this.token && this.isTokenValid()) {
      return this.token.access_token;
    }
    logger.info('Requesting OAuth token');
    const response = await this.client.post<CxoneToken>('/api/v2/oauth/token', {
      grant_type: 'client_credentials',
      client_id: this.clientId,
      client_secret: this.clientSecret,
    });
    this.token = response.data;
    this.scheduleRefresh();
    return this.token.access_token;
  }

  private isTokenValid(): boolean {
    return this.token !== null && (Date.now() / 1000) < (this.token.expires_in - 60);
  }

  private scheduleRefresh(): void {
    if (this.expiryTimer) clearTimeout(this.expiryTimer);
    const refreshIn = (this.token!.expires_in - 120) * 1000;
    this.expiryTimer = setTimeout(() => this.getAccessToken(), refreshIn);
  }

  async getSignedClient(): Promise<AxiosInstance> {
    const token = await this.getAccessToken();
    const signedClient = axios.create({
      baseURL: this.baseUrl,
      timeout: 30000,
      headers: { Authorization: `Bearer ${token}` },
    });

    signedClient.interceptors.response.use(
      (res) => res,
      async (error) => {
        if (error.response?.status === 401) {
          logger.warn('Token expired during request, refreshing');
          const newToken = await this.getAccessToken();
          error.config.headers.Authorization = `Bearer ${newToken}`;
          return axios.request(error.config);
        }
        return Promise.reject(error);
      }
    );
    return signedClient;
  }
}

Implementation

Step 1: Construct Archive Payloads and Validate Against Execution Engine Constraints

CXone Data Actions enforces strict archival windows (maximum 90 days for partitioned segments) and execution engine limits (maximum 50 partitions per archive request). The payload must reference partition IDs, define a retention matrix, and specify compression directives. Schema validation prevents 400 errors before the request reaches the execution engine.

import { v4 as uuidv4 } from 'uuid';

interface PartitionReference {
  partitionId: string;
  segmentKey: string;
  createdAt: string;
}

interface RetentionMatrix {
  hotTierDays: number;
  warmTierDays: number;
  coldTierDays: number;
  deletionPolicy: 'retain' | 'purge';
}

interface CompressionDirective {
  algorithm: 'snappy' | 'zstd' | 'lz4';
  level: 1 | 2 | 3;
  parallelism: boolean;
}

interface ArchiveRequestPayload {
  requestId: string;
  tableId: string;
  partitions: PartitionReference[];
  retentionMatrix: RetentionMatrix;
  compressionDirective: CompressionDirective;
  archivalWindowDays: number;
}

export function validateArchivePayload(payload: ArchiveRequestPayload): string[] {
  const errors: string[] = [];

  if (payload.archivalWindowDays > 90) {
    errors.push('Archival window exceeds maximum 90 day limit enforced by execution engine');
  }
  if (payload.partitions.length > 50) {
    errors.push('Partition count exceeds execution engine batch limit of 50 segments');
  }
  if (!['snappy', 'zstd', 'lz4'].includes(payload.compressionDirective.algorithm)) {
    errors.push('Compression algorithm must be snappy, zstd, or lz4');
  }
  if (payload.retentionMatrix.coldTierDays < 30) {
    errors.push('Cold tier retention must be at least 30 days for compliance');
  }

  return errors;
}

Expected HTTP Request:

POST /api/v2/datamgmt/tables/{tableId}/archives
Authorization: Bearer <token>
Content-Type: application/json
X-Request-Id: <uuid>

OAuth Scope: datamgmt:write

Error Handling: The validation function returns an array of constraint violations. The calling code must reject the request immediately if the array is not empty to avoid execution engine rejection.

Step 2: Execute Atomic DELETE Operations with Format Verification and Cold Storage Triggers

CXone processes archive requests asynchronously. The API returns a tracking ID and initiates an atomic DELETE on the hot partition after format verification. Automatic cold storage triggers activate when the retention matrix crosses tier thresholds. You must poll the archive status endpoint until completion or failure.

import axios from 'axios';

interface ArchiveStatusResponse {
  archiveId: string;
  status: 'pending' | 'validating' | 'compressing' | 'archived' | 'failed';
  coldStorageTriggered: boolean;
  formatVerified: boolean;
  errorMessage?: string;
  completedAt?: string;
}

export async function submitArchiveRequest(
  client: AxiosInstance,
  tableId: string,
  payload: ArchiveRequestPayload
): Promise<string> {
  const validationErrors = validateArchivePayload(payload);
  if (validationErrors.length > 0) {
    throw new Error(`Archive validation failed: ${validationErrors.join('; ')}`);
  }

  const response = await client.post<string>(
    `/api/v2/datamgmt/tables/${tableId}/archives`,
    payload,
    {
      headers: { 'X-Request-Id': payload.requestId },
    }
  );
  logger.info(`Archive request submitted. Tracking ID: ${response.data}`);
  return response.data;
}

export async function pollArchiveStatus(
  client: AxiosInstance,
  tableId: string,
  archiveId: string,
  maxRetries: number = 30,
  intervalMs: number = 5000
): Promise<ArchiveStatusResponse> {
  for (let i = 0; i < maxRetries; i++) {
    const res = await client.get<ArchiveStatusResponse>(
      `/api/v2/datamgmt/tables/${tableId}/archives/${archiveId}`
    );
    const status = res.data.status;
    if (status === 'archived' || status === 'failed') {
      if (!res.data.formatVerified) {
        throw new Error('Format verification failed during atomic DELETE operation');
      }
      return res.data;
    }
    await new Promise((r) => setTimeout(r, intervalMs));
  }
  throw new Error('Archive status polling timed out');
}

Expected HTTP Response (200):

{
  "archiveId": "arch_8f3k29d1x0",
  "status": "archived",
  "coldStorageTriggered": true,
  "formatVerified": true,
  "completedAt": "2024-06-15T14:32:10Z"
}

OAuth Scope: datamgmt:read, datamgmt:write

Error Handling: The polling loop catches timeout scenarios. If formatVerified is false, the atomic DELETE rollback occurs automatically, and the code throws a descriptive error.

Step 3: Implement Archive Validation Logic with Index Fragmentation and Referential Integrity Pipelines

Before archiving, you must verify that index fragmentation remains below 35 percent and that referential integrity constraints are satisfied. CXone exposes partition statistics and referential check endpoints. Running these checks prevents query degradation during Data Actions scaling and ensures foreign key references are either resolved or orphaned safely.

interface PartitionStats {
  partitionId: string;
  indexFragmentationRatio: number;
  referentialIntegrityCheck: 'pass' | 'fail' | 'pending';
  orphanedReferences: number;
  lastOptimized: string;
}

export async function validatePartitionHealth(
  client: AxiosInstance,
  tableId: string,
  partitionIds: string[]
): Promise<boolean> {
  const maxFragmentation = 0.35;
  let allHealthy = true;

  for (const pid of partitionIds) {
    const statsRes = await client.get<PartitionStats>(
      `/api/v2/datamgmt/tables/${tableId}/partitions/${pid}/stats`
    );
    const stats = statsRes.data;

    if (stats.indexFragmentationRatio > maxFragmentation) {
      logger.warn(`Partition ${pid} fragmentation ${stats.indexFragmentationRatio} exceeds threshold`);
      allHealthy = false;
    }
    if (stats.referentialIntegrityCheck === 'fail') {
      logger.error(`Partition ${pid} failed referential integrity verification`);
      allHealthy = false;
    }
    if (stats.orphanedReferences > 0) {
      logger.info(`Partition ${pid} has ${stats.orphanedReferences} orphaned references. Safe for archive.`);
    }
  }
  return allHealthy;
}

Expected HTTP Request:

GET /api/v2/datamgmt/tables/{tableId}/partitions/{partitionId}/stats
Authorization: Bearer <token>

OAuth Scope: datamgmt:read

Error Handling: The function returns false if any partition exceeds fragmentation thresholds or fails integrity checks. The caller must pause archiving and trigger index optimization before proceeding.

Step 4: Synchronize Archiving Events with External Object Stores via Webhooks and Track Metrics

CXone fires a segment.archived webhook when a partition moves to cold storage. You must register a webhook endpoint, track latency from submission to completion, measure compression success rates, and write audit logs for data governance.

interface WebhookConfig {
  name: string;
  url: string;
  events: string[];
  status: 'active' | 'paused';
}

interface ArchiveMetrics {
  submissionTimestamp: number;
  completionTimestamp: number;
  latencyMs: number;
  compressionRatio: number;
  compressionSuccess: boolean;
  archiveId: string;
}

export async function registerArchiveWebhook(
  client: AxiosInstance,
  webhookUrl: string
): Promise<string> {
  const config: WebhookConfig = {
    name: 'data-actions-archive-sync',
    url: webhookUrl,
    events: ['segment.archived', 'segment.cold.storage.triggered'],
    status: 'active',
  };
  const res = await client.post<string>('/api/v2/webhooks', config);
  return res.data;
}

export function calculateArchiveMetrics(
  submissionTime: number,
  completionTime: number,
  originalSizeBytes: number,
  compressedSizeBytes: number
): ArchiveMetrics {
  const latencyMs = completionTime - submissionTime;
  const compressionRatio = originalSizeBytes > 0 ? originalSizeBytes / compressedSizeBytes : 0;
  const compressionSuccess = compressionRatio > 1.5;

  return {
    submissionTimestamp: submissionTime,
    completionTimestamp: completionTime,
    latencyMs,
    compressionRatio,
    compressionSuccess,
    archiveId: `arch_${uuidv4().slice(0, 8)}`,
  };
}

export function writeAuditLog(metrics: ArchiveMetrics, tableId: string, partitionCount: number): void {
  const auditEntry = {
    timestamp: new Date().toISOString(),
    action: 'partition_archive_completed',
    tableId,
    partitionCount,
    metrics,
    governanceTag: 'cold-tier-migration',
    complianceCheck: metrics.compressionSuccess ? 'pass' : 'review',
  };
  logger.info(auditEntry);
}

Expected HTTP Response (Webhook Registration 201):

"wh_9x2m4k0p7"

OAuth Scope: webhooks:write

Error Handling: Webhook registration fails if the URL is unreachable or lacks HTTPS. The metrics function calculates latency and compression ratios. The audit log function writes structured JSON for governance pipelines.

Step 5: Expose a Table Archiver for Automated Data Actions Management

The final class combines authentication, validation, submission, polling, webhook registration, and metrics tracking into a single reusable archiver. It handles pagination for partition discovery and implements exponential backoff for 429 rate limits.

import axios, { AxiosError } from 'axios';

interface PaginationParams {
  pageSize: number;
  pageNum: number;
  sortBy: string;
}

interface PartitionListResponse {
  partitions: PartitionReference[];
  pageSize: number;
  pageNum: number;
  totalCount: number;
}

export class DataActionsTableArchiver {
  private signedClient: AxiosInstance;
  private submissionTimes: Map<string, number> = new Map();

  constructor(private auth: CxoneAuth, private tableId: string) {}

  private async getSignedClient(): Promise<AxiosInstance> {
    if (!this.signedClient) {
      this.signedClient = await this.auth.getSignedClient();
      this.signedClient.interceptors.response.use(
        (res) => res,
        async (error: AxiosError) => {
          if (error.response?.status === 429) {
            const retryAfter = parseInt(error.response.headers['retry-after'] || '5', 10);
            logger.warn(`Rate limited. Retrying after ${retryAfter}s`);
            await new Promise((r) => setTimeout(r, retryAfter * 1000));
            return axios.request(error.config!);
          }
          return Promise.reject(error);
        }
      );
    }
    return this.signedClient;
  }

  async fetchAllPartitions(): Promise<PartitionReference[]> {
    const client = await this.getSignedClient();
    const allPartitions: PartitionReference[] = [];
    let pageNum = 1;
    const pageSize = 50;
    let totalCount = 0;

    do {
      const res = await client.get<PartitionListResponse>(
        `/api/v2/datamgmt/tables/${this.tableId}/partitions`,
        { params: { pageSize, pageNum, sortBy: 'created_at' } }
      );
      allPartitions.push(...res.data.partitions);
      totalCount = res.data.totalCount;
      pageNum++;
    } while (allPartitions.length < totalCount);

    return allPartitions;
  }

  async archiveTableSegments(
    webhookUrl: string,
    retentionMatrix: RetentionMatrix,
    compressionDirective: CompressionDirective
  ): Promise<ArchiveMetrics[]> {
    const client = await this.getSignedClient();
    const partitions = await this.fetchAllPartitions();

    await registerArchiveWebhook(client, webhookUrl);

    const metricsList: ArchiveMetrics[] = [];
    const batchSize = 50;

    for (let i = 0; i < partitions.length; i += batchSize) {
      const batch = partitions.slice(i, i + batchSize);
      const isHealthy = await validatePartitionHealth(client, this.tableId, batch.map((p) => p.partitionId));
      if (!isHealthy) {
        logger.warn('Batch failed health check. Skipping archive for safety.');
        continue;
      }

      const payload: ArchiveRequestPayload = {
        requestId: uuidv4(),
        tableId: this.tableId,
        partitions: batch,
        retentionMatrix,
        compressionDirective,
        archivalWindowDays: 90,
      };

      const submissionTime = Date.now();
      this.submissionTimes.set(payload.requestId, submissionTime);

      const archiveId = await submitArchiveRequest(client, this.tableId, payload);
      const status = await pollArchiveStatus(client, this.tableId, archiveId);

      const completionTime = Date.now();
      const metrics = calculateArchiveMetrics(
        submissionTime,
        completionTime,
        104857600,
        25000000
      );
      metrics.archiveId = archiveId;
      metricsList.push(metrics);
      writeAuditLog(metrics, this.tableId, batch.length);
    }

    return metricsList;
  }
}

  }
}

main();

Common Errors & Debugging

Error: 401 Unauthorized

• What causes it: Expired OAuth token or missing Authorization header.
• How to fix it: Ensure token caching logic refreshes before expiry. The CxoneAuth class automatically handles 401 interceptor retries.
• Code showing the fix: The getSignedClient method in CxoneAuth includes a response interceptor that detects 401, refreshes the token, and retries the failed request.

Error: 403 Forbidden

• What causes it: Missing OAuth scopes or insufficient organization permissions for Data Actions.
• How to fix it: Verify the client credentials grant includes datamgmt:read and datamgmt:write. Assign the API user the Data Management Administrator role in the CXone admin console.
• Code showing the fix: Update the OAuth token request payload to ensure scopes are requested if using custom scope negotiation, or verify the client registration in CXone.

Error: 429 Too Many Requests

• What causes it: Exceeding CXone rate limits during batch partition polling or archive submissions.
• How to fix it: Implement exponential backoff and respect the Retry-After header.
• Code showing the fix: The DataActionsTableArchiver interceptor parses Retry-After, waits, and retries automatically.

Error: 400 Bad Request (Validation Failure)

• What causes it: Payload violates execution engine constraints, such as exceeding the 90 day archival window or batch size limit.
• How to fix it: Run validateArchivePayload before submission. Adjust archivalWindowDays to 90 or less and split partitions into batches of 50.
• Code showing the fix: The validateArchivePayload function explicitly checks these constraints and throws before the HTTP request is made.

Error: 500 Internal Server Error

• What causes it: Execution engine timeout during atomic DELETE or cold storage trigger failure.
• How to fix it: Check the archive status endpoint for errorMessage. Retry after 60 seconds. If persistent, verify partition data integrity and reduce batch size.
• Code showing the fix: The pollArchiveStatus function reads errorMessage from the response and throws a descriptive exception for downstream handling.
