Retrieving Genesys Cloud Interaction History Records via REST API with TypeScript

What You Will Build

A production-grade TypeScript module that queries Genesys Cloud conversation history, manages pagination and caching, validates retention constraints, logs audit trails, and triggers completion webhooks for analytics warehouse synchronization. It uses the @genesyscloud/api-analytics SDK and the POST /api/v2/analytics/conversations/details/query endpoint. The tutorial covers TypeScript with Node.js.

Prerequisites

• OAuth Client ID and Client Secret with analytics:conversation:view scope
• @genesyscloud/api-analytics version 13.0.0 or higher
• Node.js 18.0.0 or higher
• External dependencies: axios for webhook delivery, uuid for audit identifiers, crypto for query hashing (built-in)

Authentication Setup

Genesys Cloud uses OAuth 2.0 client credentials flow for server-to-server integrations. The following function retrieves an access token, caches it, and handles expiration. The token provides read access to analytics data.

import { PlatformClient } from '@genesyscloud/platform-client';

const AUTH_CACHE = new Map<string, { token: string; expiresAt: number }>();

export async function getAuthToken(
  clientId: string,
  clientSecret: string,
  environment: string = 'my.genesys.cloud'
): Promise<string> {
  const cacheKey = `${clientId}:${environment}`;
  const cached = AUTH_CACHE.get(cacheKey);

  if (cached && Date.now() < cached.expiresAt - 60000) {
    return cached.token;
  }

  const authUrl = `https://${environment}/oauth/token`;
  const credentials = Buffer.from(`${clientId}:${clientSecret}`).toString('base64');

  const response = await fetch(authUrl, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded',
      'Authorization': `Basic ${credentials}`
    },
    body: 'grant_type=client_credentials'
  });

  if (!response.ok) {
    const errorText = await response.text();
    throw new Error(`OAuth authentication failed (${response.status}): ${errorText}`);
  }

  const data = await response.json() as { access_token: string; expires_in: number };
  const expiresAt = Date.now() + (data.expires_in * 1000);

  AUTH_CACHE.set(cacheKey, { token: data.access_token, expiresAt });
  return data.access_token;
}

Implementation

Step 1: Query Payload Construction and Validation

The analytics query endpoint requires a structured JSON body. You must define date boundaries, data category directives, and interaction ID filters. Genesys Cloud enforces a maximum query size of 1000 records per request and restricts date ranges based on your data retention policy. The following function validates inputs before transmission.

export interface QueryConfig {
  dateFrom: string;
  dateTo: string;
  interactionIds: string[];
  dataCategory: 'conversation' | 'wrapup' | 'disposition' | 'routing';
  maxRecordsPerRequest: number;
  maxRetentionDays: number;
}

export function validateQueryConfig(config: QueryConfig): void {
  if (config.maxRecordsPerRequest > 1000) {
    throw new Error('Query size exceeds Genesys Cloud maximum limit of 1000 records.');
  }

  const fromDate = new Date(config.dateFrom);
  const toDate = new Date(config.dateTo);
  const diffDays = (toDate.getTime() - fromDate.getTime()) / (1000 * 60 * 60 * 24);

  if (diffDays > config.maxRetentionDays) {
    throw new Error(`Date range exceeds retention constraint of ${config.maxRetentionDays} days.`);
  }

  if (diffDays <= 0) {
    throw new Error('Invalid date range. End date must be after start date.');
  }

  if (config.interactionIds.length === 0) {
    throw new Error('Interaction ID array cannot be empty.');
  }
}

export function buildQueryPayload(config: QueryConfig, continuationToken: string | null) {
  return {
    dateFrom: config.dateFrom,
    dateTo: config.dateTo,
    view: config.dataCategory,
    filter: [
      {
        type: 'conversation',
        path: 'id',
        op: 'in',
        value: config.interactionIds
      }
    ],
    size: config.maxRecordsPerRequest,
    continuationToken: continuationToken
  };
}

Step 2: Paginated Fetching with Cursor Management and Caching

The API returns a continuationToken when additional pages exist. You must pass this token back in the next request until it returns null. The following implementation includes an in-memory cache with time-to-live expiration and automatic cursor rotation. It also implements exponential backoff for rate limit responses.

import { AnalyticsApi } from '@genesyscloud/api-analytics';
import { createHash } from 'crypto';

interface CacheEntry<T> {
  data: T;
  expiresAt: number;
}

class QueryCache<T> {
  private store = new Map<string, CacheEntry<T>>();
  constructor(private ttlMs: number) {}

  get(key: string): T | null {
    const entry = this.store.get(key);
    if (!entry) return null;
    if (Date.now() > entry.expiresAt) {
      this.store.delete(key);
      return null;
    }
    return entry.data;
  }

  set(key: string, data: T): void {
    this.store.set(key, { data, expiresAt: Date.now() + this.ttlMs });
  }
}

export async function fetchPaginatedRecords(
  api: AnalyticsApi,
  config: QueryConfig,
  cache: QueryCache<any[]>
): Promise<any[]> {
  const allRecords: any[] = [];
  let continuationToken: string | null = null;
  let retryCount = 0;

  while (true) {
    const cacheKey = createHash('sha256')
      .update(JSON.stringify({ ...config, continuationToken }))
      .digest('hex');

    const cachedResult = cache.get(cacheKey);
    if (cachedResult && continuationToken === null) {
      return cachedResult;
    }

    const payload = buildQueryPayload(config, continuationToken);

    try {
      const response = await api.postAnalyticsConversationsDetailsQuery(payload);
      
      if (response.statusCode === 429) {
        const waitTime = Math.min(1000 * Math.pow(2, retryCount), 30000);
        await new Promise(resolve => setTimeout(resolve, waitTime));
        retryCount++;
        continue;
      }

      if (!response.body || !response.body.entities) {
        break;
      }

      allRecords.push(...response.body.entities);
      continuationToken = response.body.continuationToken || null;
      retryCount = 0;

      if (!continuationToken) {
        cache.set(cacheKey, allRecords);
        break;
      }
    } catch (error: any) {
      if (error.status === 429) {
        const waitTime = Math.min(1000 * Math.pow(2, retryCount), 30000);
        await new Promise(resolve => setTimeout(resolve, waitTime));
        retryCount++;
        continue;
      }
      throw error;
    }
  }

  return allRecords;
}

Step 3: Validation Pipeline and Audit Logging

Before processing data, you must verify that the authenticated client has permission to view the requested interaction IDs. The following function performs a lightweight availability check and generates structured audit logs for compliance tracking.

import { v4 as uuidv4 } from 'uuid';

export interface AuditLog {
  auditId: string;
  timestamp: string;
  userId: string;
  environment: string;
  queryHash: string;
  recordsRequested: number;
  recordsRetrieved: number;
  latencyMs: number;
  status: 'success' | 'partial' | 'failed';
  errorMessage: string | null;
}

export function generateAuditLog(
  config: QueryConfig,
  startTime: number,
  recordsRetrieved: number,
  status: AuditLog['status'],
  error: string | null
): AuditLog {
  return {
    auditId: uuidv4(),
    timestamp: new Date().toISOString(),
    userId: 'service-account',
    environment: 'my.genesys.cloud',
    queryHash: createHash('sha256').update(JSON.stringify(config)).digest('hex'),
    recordsRequested: config.interactionIds.length,
    recordsRetrieved,
    latencyMs: Date.now() - startTime,
    status,
    errorMessage: error
  };
}

export async function verifyAccessPermissions(api: AnalyticsApi, config: QueryConfig): Promise<boolean> {
  const dryRunPayload = buildQueryPayload({ ...config, maxRecordsPerRequest: 1 }, null);
  
  try {
    const response = await api.postAnalyticsConversationsDetailsQuery(dryRunPayload);
    return response.statusCode >= 200 && response.statusCode < 300;
  } catch (error: any) {
    if (error.status === 403) {
      throw new Error('Access denied. The client lacks analytics:conversation:view scope or organization permissions.');
    }
    throw error;
  }
}

Step 4: Webhook Synchronization and Metrics Tracking

After retrieval completes, you must notify external analytics warehouses and record operational metrics. The following function calculates data completeness rates, measures latency, and delivers a completion payload to a configured webhook endpoint.

import axios from 'axios';

export interface RetrievalMetrics {
  totalLatencyMs: number;
  cacheHitRate: number;
  completenessRate: number;
  totalRecordsFetched: number;
  paginationDepth: number;
}

export async function triggerCompletionWebhook(
  webhookUrl: string,
  metrics: RetrievalMetrics,
  auditLog: AuditLog
): Promise<void> {
  const payload = {
    event: 'interaction_history_retrieval_complete',
    timestamp: new Date().toISOString(),
    metrics,
    audit: auditLog
  };

  try {
    await axios.post(webhookUrl, payload, {
      headers: { 'Content-Type': 'application/json' },
      timeout: 5000
    });
  } catch (error: any) {
    console.error(`Webhook delivery failed: ${error.message}`);
  }
}

export function calculateMetrics(
  startTime: number,
  totalRecords: number,
  requestedIds: number,
  cacheHits: number,
  totalRequests: number
): RetrievalMetrics {
  return {
    totalLatencyMs: Date.now() - startTime,
    cacheHitRate: totalRequests > 0 ? cacheHits / totalRequests : 0,
    completenessRate: requestedIds > 0 ? totalRecords / requestedIds : 0,
    totalRecordsFetched: totalRecords,
    paginationDepth: Math.ceil(totalRecords / 1000)
  };
}

Complete Working Example

The following module combines all components into a single retriever class. It exposes a synchronous-style async method that handles authentication, validation, pagination, caching, metrics, and webhook delivery. Replace the placeholder credentials and webhook URL before execution.

import { AnalyticsApi } from '@genesyscloud/api-analytics';
import { getAuthToken } from './auth';
import { validateQueryConfig, buildQueryPayload, fetchPaginatedRecords } from './query';
import { verifyAccessPermissions, generateAuditLog } from './audit';
import { calculateMetrics, triggerCompletionWebhook } from './metrics';

export class InteractionHistoryRetriever {
  private api: AnalyticsApi;
  private cache: any;

  constructor(
    private clientId: string,
    private clientSecret: string,
    private environment: string,
    private webhookUrl: string,
    private cacheTtlMs: number = 300000
  ) {
    this.api = new AnalyticsApi();
    this.cache = new (class extends Map {
      private ttl: number;
      constructor(ttl: number) { super(); this.ttl = ttl; }
      get(key: string) {
        const entry = super.get(key);
        if (!entry) return null;
        if (Date.now() > entry.expiresAt) { super.delete(key); return null; }
        return entry.data;
      }
      set(key: string, data: any) {
        super.set(key, { data, expiresAt: Date.now() + this.ttl });
      }
    })(this.cacheTtlMs);
  }

  async retrieve(config: {
    dateFrom: string;
    dateTo: string;
    interactionIds: string[];
    dataCategory: 'conversation' | 'wrapup' | 'disposition' | 'routing';
    maxRecordsPerRequest?: number;
    maxRetentionDays?: number;
  }) {
    const startTime = Date.now();
    const queryConfig = {
      ...config,
      maxRecordsPerRequest: config.maxRecordsPerRequest || 1000,
      maxRetentionDays: config.maxRetentionDays || 365
    };

    validateQueryConfig(queryConfig);

    const token = await getAuthToken(this.clientId, this.clientSecret, this.environment);
    this.api.setAccessToken(token);

    const hasAccess = await verifyAccessPermissions(this.api, queryConfig);
    if (!hasAccess) {
      throw new Error('Permission verification failed.');
    }

    const records = await fetchPaginatedRecords(this.api, queryConfig, this.cache);
    const metrics = calculateMetrics(startTime, records.length, queryConfig.interactionIds.length, 0, 1);
    const auditLog = generateAuditLog(queryConfig, startTime, records.length, 'success', null);

    await triggerCompletionWebhook(this.webhookUrl, metrics, auditLog);

    return {
      records,
      metrics,
      auditLog
    };
  }
}

// Execution block
async function main() {
  const retriever = new InteractionHistoryRetriever(
    'YOUR_CLIENT_ID',
    'YOUR_CLIENT_SECRET',
    'my.genesys.cloud',
    'https://your-analytics-warehouse.example.com/api/v1/sync/genesys-history'
  );

  try {
    const result = await retriever.retrieve({
      dateFrom: '2024-01-01T00:00:00.000Z',
      dateTo: '2024-01-02T23:59:59.999Z',
      interactionIds: ['conv-12345', 'conv-67890', 'conv-11223'],
      dataCategory: 'conversation',
      maxRetentionDays: 365
    });

    console.log(`Retrieved ${result.records.length} interactions.`);
    console.log(JSON.stringify(result.auditLog, null, 2));
  } catch (error: any) {
    console.error(`Retrieval failed: ${error.message}`);
  }
}

main();

Common Errors & Debugging

Error: HTTP 401 Unauthorized

• Cause: The OAuth token has expired, the client credentials are incorrect, or the token was not attached to the SDK instance.
• Fix: Verify the client ID and secret match the Genesys Cloud administration console. Ensure api.setAccessToken(token) is called before any analytics request. Implement automatic token refresh by checking expiration before each batch.

Error: HTTP 403 Forbidden

• Cause: The OAuth client lacks the analytics:conversation:view scope, or the user associated with the service account does not have organization-level analytics permissions.
• Fix: Navigate to Admin > Security > OAuth Clients, select your client, and add analytics:conversation:view to the scope list. Assign the service account to a role with Analytics Read permissions.

Error: HTTP 429 Too Many Requests

• Cause: The integration exceeded Genesys Cloud rate limits. Analytics endpoints typically allow 100 requests per minute per client.
• Fix: The provided implementation includes exponential backoff. If failures persist, reduce maxRecordsPerRequest to 500, introduce a fixed delay between continuation loops, or implement a request queue with concurrency limits.

Error: HTTP 400 Bad Request

• Cause: The date range exceeds retention limits, the size parameter exceeds 1000, or the JSON body contains invalid field names.
• Fix: Validate maxRecordsPerRequest against the 1000 limit. Ensure dateFrom and dateTo fall within your organization’s retention window. Use the validateQueryConfig function before transmission.

Error: Empty Response Despite Valid Query

• Cause: The interaction IDs do not exist within the specified date range, or the data category directive filters out the records.
• Fix: Verify the conversation IDs against Genesys Cloud administration. Change dataCategory to wrapup or routing if the conversations concluded outside the primary window. Check the completenessRate metric to identify partial matches.
