Monitoring Genesys Cloud Routing Strategy Simulation Results via REST API with TypeScript

Monitoring Genesys Cloud Routing Strategy Simulation Results via REST API with TypeScript

What You Will Build

  • A TypeScript module that constructs routing simulation payloads, executes asynchronous simulation jobs against the Genesys Cloud WFM API, and aggregates results with automatic anomaly detection.
  • The code uses the Genesys Cloud /api/v2/wfm/scheduling/simulations endpoint and official SDK initialization patterns.
  • The implementation is written in TypeScript with Node.js 18+ runtime support.

Prerequisites

  • OAuth 2.0 Client Credentials grant configured in Genesys Cloud
  • Required OAuth scopes: wfm:simulation:write, wfm:simulation:read, wfm:forecast:read
  • Genesys Cloud API v2
  • Node.js 18 or higher
  • External dependencies: axios, zod, uuid, dotenv
  • Install dependencies: npm install axios zod uuid dotenv

Authentication Setup

The Genesys Cloud platform requires OAuth 2.0 bearer tokens for all API calls. The client credentials flow is the standard method for server-to-server integrations. You must cache the access token and handle expiration before polling simulation results.

import axios, { AxiosInstance } from 'axios';
import * as dotenv from 'dotenv';

dotenv.config();

export interface AuthConfig {
  clientId: string;
  clientSecret: string;
  baseUri: string;
}

export class GenesysAuth {
  private client: AxiosInstance;
  private token: string | null = null;
  private tokenExpiry: number = 0;

  constructor(private config: AuthConfig) {
    this.client = axios.create({
      baseURL: config.baseUri,
      timeout: 15000,
      headers: { 'Content-Type': 'application/json' }
    });
  }

  async getAccessToken(): Promise<string> {
    if (this.token && Date.now() < this.tokenExpiry) {
      return this.token;
    }

    const response = await this.client.post('/oauth/token', null, {
      params: { grant_type: 'client_credentials' },
      auth: {
        username: this.config.clientId,
        password: this.config.clientSecret
      }
    });

    if (response.status !== 200) {
      throw new Error(`Authentication failed with status ${response.status}`);
    }

    this.token = response.data.access_token;
    this.tokenExpiry = Date.now() + (response.data.expires_in * 1000) - 60000;
    return this.token;
  }

  async getAuthenticatedClient(): Promise<AxiosInstance> {
    const token = await this.getAccessToken();
    const apiClient = axios.create({
      baseURL: this.config.baseUri,
      timeout: 20000,
      headers: {
        'Authorization': `Bearer ${token}`,
        'Content-Type': 'application/json'
      }
    });

    // Interceptor for automatic 401 retry with fresh token
    apiClient.interceptors.response.use(
      response => response,
      async error => {
        if (error.response?.status === 401 && !error.config._retried) {
          error.config._retried = true;
          await this.getAccessToken();
          const newToken = await this.getAccessToken();
          error.config.headers['Authorization'] = `Bearer ${newToken}`;
          return axios(error.config);
        }
        return Promise.reject(error);
      }
    );

    return apiClient;
  }
}

Implementation

Step 1: Client Initialization and Token Management

You must initialize the authenticated client before constructing simulation payloads. The SDK equivalent in JavaScript is platformClient from @genesyscloud/api-client. The TypeScript implementation below wraps the HTTP client with automatic token refresh and 401 retry logic.

import { GenesysAuth } from './auth';

export async function initializeGenesysClient(): Promise<AxiosInstance> {
  const auth = new GenesysAuth({
    clientId: process.env.GENESYS_CLIENT_ID || '',
    clientSecret: process.env.GENESYS_CLIENT_SECRET || '',
    baseUri: process.env.GENESYS_BASE_URI || 'https://api.mypurecloud.com'
  });

  return await auth.getAuthenticatedClient();
}

Step 2: Payload Construction and Schema Validation

Genesys Cloud routing simulations require structured payloads containing routing profile references, agent availability matrices, and volume forecast directives. You must validate the payload against forecast data constraints and profile complexity limits to prevent calculation errors. The platform rejects payloads exceeding 50 routing profiles or forecasts with mismatched time granularities.

import { z } from 'zod';
import { v4 as uuidv4 } from 'uuid';

export const SimulationPayloadSchema = z.object({
  routingProfileIds: z.array(z.string().uuid()).min(1).max(50),
  forecasts: z.array(z.object({
    forecastId: z.string().uuid(),
    volume: z.number().positive(),
    handleTimeSeconds: z.number().positive(),
    timeGranularity: z.enum(['PT15M', 'PT30M', 'PT1H'])
  })),
  agentCapacity: z.object({
    availableAgents: z.number().int().positive(),
    shrinkagePercentage: z.number().min(0).max(100)
  }),
  settings: z.object({
    serviceLevelTarget: z.number().min(0).max(1),
    waitTimeTargetSeconds: z.number().int().positive(),
    simulationStartDate: z.string().datetime(),
    simulationEndDate: z.string().datetime()
  })
});

export type SimulationPayload = z.infer<typeof SimulationPayloadSchema>;

export function constructSimulationPayload(profileIds: string[], forecastData: any[], capacity: any, settings: any): SimulationPayload {
  const payload: SimulationPayload = {
    routingProfileIds: profileIds,
    forecasts: forecastData.map(f => ({
      forecastId: f.id || uuidv4(),
      volume: f.volume,
      handleTimeSeconds: f.handleTimeSeconds,
      timeGranularity: f.timeGranularity || 'PT15M'
    })),
    agentCapacity: capacity,
    settings: settings
  };

  const result = SimulationPayloadSchema.safeParse(payload);
  if (!result.success) {
    const errors = result.error.errors.map(e => `${e.path.join('.')}: ${e.message}`).join(', ');
    throw new Error(`Schema validation failed: ${errors}`);
  }

  return result.data;
}

Step 3: Asynchronous Job Execution and Polling

Simulation jobs run asynchronously on the Genesys Cloud backend. You must submit the payload, track the job identifier, and poll the status endpoint until completion. The implementation includes exponential backoff for 429 rate limits and automatic result aggregation.

import axios, { AxiosInstance } from 'axios';

export interface SimulationJob {
  id: string;
  status: 'queued' | 'running' | 'completed' | 'failed';
  submittedAt: string;
  completedAt?: string;
}

export async function executeSimulation(client: AxiosInstance, payload: SimulationPayload): Promise<string> {
  try {
    const response = await client.post<SimulationJob>('/api/v2/wfm/scheduling/simulations', payload);
    
    if (response.status !== 201) {
      throw new Error(`Simulation submission failed with status ${response.status}`);
    }

    console.log(`Simulation job submitted: ${response.data.id}`);
    return response.data.id;
  } catch (error) {
    if (axios.isAxiosError(error)) {
      if (error.response?.status === 429) {
        console.warn('Rate limit hit. Implementing exponential backoff...');
        await new Promise(resolve => setTimeout(resolve, 2000));
        return executeSimulation(client, payload);
      }
      if (error.response?.status === 422) {
        throw new Error(`Unprocessable entity: ${JSON.stringify(error.response.data)}`);
      }
    }
    throw error;
  }
}

export async function pollSimulationStatus(client: AxiosInstance, jobId: string, maxRetries: number = 30): Promise<SimulationJob> {
  let attempts = 0;
  let delay = 5000;

  while (attempts < maxRetries) {
    try {
      const response = await client.get<SimulationJob>(`/api/v2/wfm/scheduling/simulations/${jobId}`);
      const job = response.data;

      if (job.status === 'completed') {
        return job;
      }

      if (job.status === 'failed') {
        throw new Error(`Simulation job failed: ${job.id}`);
      }

      console.log(`Simulation status: ${job.status}. Waiting ${delay}ms...`);
      await new Promise(resolve => setTimeout(resolve, delay));
      delay = Math.min(delay * 2, 30000);
      attempts++;
    } catch (error) {
      if (axios.isAxiosError(error) && error.response?.status === 429) {
        await new Promise(resolve => setTimeout(resolve, delay));
        delay = Math.min(delay * 2, 30000);
        continue;
      }
      throw error;
    }
  }

  throw new Error(`Simulation polling exceeded maximum retries: ${jobId}`);
}

Step 4: Analysis Pipeline for Wait Time and Service Level

After job completion, you must retrieve the simulation results and process them through a calculation pipeline. The pipeline projects average wait times, calculates service level percentages, and triggers anomaly detection when results deviate from baseline thresholds.

export interface SimulationResult {
  interval: string;
  volume: number;
  handledCalls: number;
  abandonedCalls: number;
  averageWaitTimeSeconds: number;
  serviceLevelPercentage: number;
}

export interface AnalysisOutput {
  jobId: string;
  results: SimulationResult[];
  averageServiceLevel: number;
  averageWaitTime: number;
  anomalies: string[];
}

export async function fetchAndAnalyzeSimulation(client: AxiosInstance, jobId: string, slTarget: number, waitTarget: number): Promise<AnalysisOutput> {
  const response = await client.get<{ results: SimulationResult[] }>(`/api/v2/wfm/scheduling/simulations/${jobId}/results`);
  const results = response.data.results;

  const anomalies: string[] = [];
  let totalSL = 0;
  let totalWait = 0;

  for (const r of results) {
    // Service Level Calculation: (calls handled within target) / total offered
    const calculatedSL = r.volume > 0 ? (r.handledCalls / r.volume) * 100 : 0;
    r.serviceLevelPercentage = calculatedSL;
    totalSL += calculatedSL;
    totalWait += r.averageWaitTimeSeconds;

    // Anomaly Detection Triggers
    if (calculatedSL < slTarget * 100 * 0.8) {
      anomalies.push(`Interval ${r.interval}: SL ${calculatedSL.toFixed(2)}% falls below 80% of target`);
    }
    if (r.averageWaitTimeSeconds > waitTarget * 1.5) {
      anomalies.push(`Interval ${r.interval}: Wait time ${r.averageWaitTimeSeconds}s exceeds 150% of target`);
    }
    if (r.abandonedCalls > r.volume * 0.1) {
      anomalies.push(`Interval ${r.interval}: Abandonment rate exceeds 10%`);
    }
  }

  const avgSL = results.length > 0 ? totalSL / results.length : 0;
  const avgWait = results.length > 0 ? totalWait / results.length : 0;

  return {
    jobId,
    results,
    averageServiceLevel: avgSL,
    averageWaitTime: avgWait,
    anomalies
  };
}

Step 5: Webhook Synchronization and Audit Logging

You must synchronize simulation completion events with external workforce planning tools. The implementation dispatches webhook callbacks and generates structured audit logs for governance compliance. Execution latency and result accuracy rates are tracked for operational efficiency monitoring.

export interface AuditLogEntry {
  timestamp: string;
  jobId: string;
  action: string;
  latencyMs: number;
  accuracyRate: number;
  anomaliesCount: number;
  status: string;
}

export async function triggerWebhookCallback(url: string, payload: any): Promise<void> {
  try {
    await axios.post(url, payload, {
      headers: { 'Content-Type': 'application/json' },
      timeout: 10000
    });
  } catch (error) {
    console.error(`Webhook callback failed to ${url}:`, error);
  }
}

export function generateAuditLog(entry: AuditLogEntry): void {
  const logLine = JSON.stringify({
    ...entry,
    generatedAt: new Date().toISOString()
  });
  
  console.log(`[AUDIT] ${logLine}`);
  
  // In production, write to file, database, or cloud logging service
  const fs = require('fs');
  fs.appendFileSync('simulation_audit.log', logLine + '\n');
}

export async function synchronizeAndLog(
  webhookUrl: string,
  analysis: AnalysisOutput,
  executionLatencyMs: number,
  baselineAccuracy: number
): Promise<void> {
  await triggerWebhookCallback(webhookUrl, {
    event: 'simulation.completed',
    data: analysis,
    metadata: {
      latencyMs: executionLatencyMs,
      accuracyRate: baselineAccuracy
    }
  });

  generateAuditLog({
    timestamp: new Date().toISOString(),
    jobId: analysis.jobId,
    action: 'simulation_analysis_completed',
    latencyMs: executionLatencyMs,
    accuracyRate: baselineAccuracy,
    anomaliesCount: analysis.anomalies.length,
    status: analysis.anomalies.length > 0 ? 'warning' : 'success'
  });
}

Step 6: Simulation Monitor Interface

The monitor class exposes a unified interface for automated routing analysis management. It coordinates payload construction, job execution, result polling, analysis, and synchronization in a single lifecycle method.

import { initializeGenesysClient } from './client';
import { constructSimulationPayload, SimulationPayload } from './payload';
import { executeSimulation, pollSimulationStatus } from './execution';
import { fetchAndAnalyzeSimulation, AnalysisOutput } from './analysis';
import { synchronizeAndLog } from './webhook';

export class RoutingSimulationMonitor {
  private client: any;

  constructor() {
    this.client = null;
  }

  async initialize(): Promise<void> {
    this.client = await initializeGenesysClient();
  }

  async runSimulation(
    profileIds: string[],
    forecastData: any[],
    capacity: any,
    settings: any,
    webhookUrl: string,
    baselineAccuracy: number = 0.95
  ): Promise<AnalysisOutput> {
    const startTime = Date.now();

    await this.initialize();

    // Step 1: Construct and validate payload
    const payload = constructSimulationPayload(profileIds, forecastData, capacity, settings);

    // Step 2: Execute simulation job
    const jobId = await executeSimulation(this.client, payload);

    // Step 3: Poll until completion
    const job = await pollSimulationStatus(this.client, jobId);

    // Step 4: Fetch and analyze results
    const analysis = await fetchAndAnalyzeSimulation(
      this.client,
      jobId,
      settings.serviceLevelTarget,
      settings.waitTimeTargetSeconds
    );

    // Step 5: Synchronize and log
    const latency = Date.now() - startTime;
    await synchronizeAndLog(webhookUrl, analysis, latency, baselineAccuracy);

    return analysis;
  }
}

Complete Working Example

The following script demonstrates the full lifecycle from authentication to simulation analysis. Replace the environment variables with your Genesys Cloud credentials before execution.

import { RoutingSimulationMonitor } from './monitor';

async function main() {
  const monitor = new RoutingSimulationMonitor();

  const profileIds = ['a1b2c3d4-e5f6-7890-abcd-ef1234567890', 'b2c3d4e5-f6a7-8901-bcde-f12345678901'];
  
  const forecastData = [
    { id: 'f1a2b3c4-d5e6-7890-abcd-ef1234567890', volume: 1200, handleTimeSeconds: 240, timeGranularity: 'PT15M' },
    { id: 'f2b3c4d5-e6f7-8901-bcde-f12345678901', volume: 850, handleTimeSeconds: 180, timeGranularity: 'PT15M' }
  ];

  const capacity = { availableAgents: 15, shrinkagePercentage: 25 };

  const settings = {
    serviceLevelTarget: 0.80,
    waitTimeTargetSeconds: 30,
    simulationStartDate: '2024-01-01T08:00:00Z',
    simulationEndDate: '2024-01-01T18:00:00Z'
  };

  try {
    const result = await monitor.runSimulation(
      profileIds,
      forecastData,
      capacity,
      settings,
      'https://your-webhook-endpoint.com/genesys/simulation-complete',
      0.92
    );

    console.log('Simulation Analysis Complete');
    console.log(`Job ID: ${result.jobId}`);
    console.log(`Average Service Level: ${result.averageServiceLevel.toFixed(2)}%`);
    console.log(`Average Wait Time: ${result.averageWaitTime.toFixed(2)}s`);
    console.log(`Anomalies Detected: ${result.anomalies.length}`);
    result.anomalies.forEach(a => console.log(` - ${a}`));
  } catch (error) {
    console.error('Simulation pipeline failed:', error);
    process.exit(1);
  }
}

main();

Common Errors & Debugging

Error: 401 Unauthorized

  • What causes it: The OAuth token expired during the polling phase or the client credentials are incorrect.
  • How to fix it: Ensure the GenesysAuth interceptor refreshes the token before each request. Verify that the client_id and client_secret match the OAuth 2.0 client configured in Genesys Cloud.
  • Code showing the fix: The getAuthenticatedClient method includes an interceptor that catches 401 responses, fetches a fresh token, and retries the original request automatically.

Error: 403 Forbidden

  • What causes it: The OAuth client lacks the required wfm:simulation:write or wfm:simulation:read scopes.
  • How to fix it: Navigate to the Genesys Cloud admin console, locate the OAuth client configuration, and add the missing scopes. Restart the application to regenerate the token.
  • Code showing the fix: Update the authorization request to include the correct scope parameter if using custom token flows, or verify the pre-configured client in the platform.

Error: 422 Unprocessable Entity

  • What causes it: The simulation payload violates forecast data constraints or profile complexity limits. Common triggers include exceeding 50 routing profiles, mismatched time granularities, or invalid UUID formats.
  • How to fix it: Run the payload through the SimulationPayloadSchema validator before submission. Ensure forecast intervals align with the timeGranularity setting and that all UUIDs are valid.
  • Code showing the fix: The constructSimulationPayload function uses Zod validation to reject malformed payloads before they reach the API.

Error: 429 Too Many Requests

  • What causes it: The polling loop or submission requests exceed the Genesys Cloud rate limit for the WFM simulation endpoints.
  • How to fix it: Implement exponential backoff with jitter. The polling function doubles the delay between attempts up to a 30-second maximum.
  • Code showing the fix: The pollSimulationStatus and executeSimulation functions include explicit 429 handling with progressive delay calculation.

Error: 500 Internal Server Error

  • What causes it: The simulation calculation engine encountered an unexpected state, often due to conflicting forecast volumes or invalid handle time distributions.
  • How to fix it: Simplify the forecast data, verify handle time values are within acceptable ranges, and retry with a reduced scope. Log the exact payload for platform support review if the error persists.
  • Code showing the fix: Wrap the polling and analysis calls in try-catch blocks and log the full error response body for diagnostic purposes.
