Routing Genesys Cloud Supervisor Escalation Signals via Agent Assist API with Node.js

What You Will Build

This tutorial builds a Node.js escalation router that constructs routing payloads containing escalation references, priority matrices, and forward directives, validates them against agent availability and maximum concurrent alert limits, processes severity scoring and on-call rotation logic via WebSocket event streams, and synchronizes routing events with external ITSM systems via webhooks. The implementation uses the Genesys Cloud Platform API v2, specifically the Agent Assist, Routing, and User endpoints, combined with the real-time analytics events WebSocket. The code is written in Node.js using the official @genesys/cloud-purecloud-sdk, ws, and axios packages.

Prerequisites

• OAuth client type: Confidential client using the client credentials flow. Required scopes: agentassist:prompt:write, routing:user:view, routing:queue:view, userprofile:view, conversation:query, analytics:events:view.
• SDK version: @genesys/cloud-purecloud-sdk v146 or higher.
• Language/runtime: Node.js 18 LTS or higher.
• External dependencies: npm install @genesys/cloud-purecloud-sdk ws axios dotenv uuid

Authentication Setup

The Genesys Cloud JavaScript SDK handles token acquisition and automatic refresh when configured with client credentials. You must initialize the PlatformClient with your organization region, client ID, and client secret. The SDK caches the access token in memory and requests a new token before expiration.

const { PlatformClient } = require('@genesys/cloud-purecloud-sdk');
require('dotenv').config();

const REGION = process.env.GENESYS_REGION || 'us';
const CLIENT_ID = process.env.GENESYS_CLIENT_ID;
const CLIENT_SECRET = process.env.GENESYS_CLIENT_SECRET;

const platformClient = PlatformClient.create({
  clientId: CLIENT_ID,
  clientSecret: CLIENT_SECRET,
  region: REGION
});

async function authenticate() {
  try {
    await platformClient.login();
    const tokenInfo = platformClient.getAccessToken();
    console.log('Authentication successful. Token expires at:', tokenInfo.expiresIn);
    return platformClient;
  } catch (error) {
    console.error('Authentication failed:', error.response?.data || error.message);
    process.exit(1);
  }
}

Implementation

Step 1: Construct Escalation Payload and Validate Routing Schema

The routing payload must contain an escalation reference, a priority matrix, and a forward directive. Before submission, the router validates the target agent against availability constraints, maximum concurrent alert limits, snooze policies, and acknowledgment verification. This step prevents routing failure by rejecting payloads that violate operational thresholds.

const { RoutingApi, UsersApi } = require('@genesys/cloud-purecloud-sdk');
const { v4: uuidv4 } = require('uuid');

const routingApi = new RoutingApi(platformClient);
const usersApi = new UsersApi(platformClient);

const MAX_CONCURRENT_ALERTS = 3;
const SNOOZE_WINDOW_MS = 300000; // 5 minutes

async function validateRoutingSchema(userId, payload) {
  // HTTP GET /api/v2/routing/users/{userId}/routingstatus
  // Headers: Authorization: Bearer <token>
  // Response: { status: 'available', statusUpdatedTimestamp: '2024-01-15T10:30:00.000Z' }
  const routingStatus = await routingApi.getRoutingUserRoutingStatus(userId);
  
  if (routingStatus.status !== 'available') {
    throw new Error(`Routing validation failed: User ${userId} status is ${routingStatus.status}`);
  }

  // HTTP GET /api/v2/users/{userId}
  // Headers: Authorization: Bearer <token>
  // Response: { id, name, customAttributes: { lastAckTimestamp, activeAlerts, snoozeUntil } }
  const userProfile = await usersApi.getUser(userId);
  const customAttrs = userProfile.customAttributes || {};
  const activeAlerts = parseInt(customAttrs.activeAlerts || '0', 10);
  const snoozeUntil = customAttrs.snoozeUntil ? new Date(customAttrs.snoozeUntil).getTime() : 0;

  if (activeAlerts >= MAX_CONCURRENT_ALERTS) {
    throw new Error(`Routing validation failed: User ${userId} has reached maximum concurrent alert limit (${MAX_CONCURRENT_ALERTS})`);
  }

  if (Date.now() < snoozeUntil) {
    throw new Error(`Routing validation failed: User ${userId} is under snooze policy until ${customAttrs.snoozeUntil}`);
  }

  // Acknowledgment verification pipeline
  const lastAck = customAttrs.lastAckTimestamp ? new Date(customAttrs.lastAckTimestamp).getTime() : 0;
  const ackWindowMs = 600000; // 10 minutes
  if (lastAck > 0 && Date.now() - lastAck < ackWindowMs && !customAttrs.acknowledgedCurrentEscalation) {
    throw new Error(`Routing validation failed: Pending acknowledgment required for user ${userId}`);
  }

  // Attach validation metadata to payload
  payload.validationTimestamp = new Date().toISOString();
  payload.routingReference = uuidv4();
  return payload;
}

Step 2: Process Severity Scoring and On-Call Rotation Logic via WebSocket

The router connects to the Genesys Cloud real-time events WebSocket to monitor routing signals. Incoming messages undergo atomic text operations with format verification. The router calculates severity scores based on conversation metadata and evaluates on-call rotation logic to determine the next eligible supervisor.

const WebSocket = require('ws');

const WS_URL = `wss://api.${REGION}.genesys.cloud/api/v2/analytics/events/ws`;

function createWebSocketSubscriber() {
  const ws = new WebSocket(WS_URL);
  
  ws.on('open', () => {
    // Subscribe to routing and conversation events
    const subscription = {
      type: 'subscribe',
      eventNames: ['routing.routingStatusChange', 'conversation.update']
    };
    ws.send(JSON.stringify(subscription));
    console.log('WebSocket connected and subscribed to routing signals');
  });

  ws.on('message', (data) => {
    try {
      const message = JSON.parse(data.toString());
      if (!validateWebSocketFormat(message)) {
        console.warn('WebSocket format verification failed. Discarding message.');
        return;
      }
      processEscalationSignal(message);
    } catch (error) {
      console.error('WebSocket message parsing error:', error.message);
    }
  });

  ws.on('error', (error) => {
    console.error('WebSocket connection error:', error.message);
  });

  return ws;
}

function validateWebSocketFormat(message) {
  const requiredFields = ['type', 'data', 'timestamp'];
  return requiredFields.every(field => field in message) && typeof message.type === 'string';
}

async function processEscalationSignal(message) {
  const event = message.data;
  if (event.type !== 'escalation.triggered') return;

  const severityScore = calculateSeverity(event.metadata);
  const rotationTarget = evaluateOnCallRotation(event.queueId, severityScore);

  const routingPayload = {
    escalationReference: event.conversationId,
    priorityMatrix: {
      severity: severityScore,
      slaBreaching: event.slaBreaching,
      customerTier: event.customerTier
    },
    forwardDirective: {
      targetUserId: rotationTarget,
      action: 'supervisor_takeover',
      timeoutMs: 120000
    }
  };

  try {
    await validateRoutingSchema(rotationTarget, routingPayload);
    await triggerAgentAssistPrompt(routingPayload);
    await syncWithITSMWebhook(routingPayload);
    trackLatencyAndAudit('route_success', routingPayload);
  } catch (validationError) {
    console.error('Routing validation rejected payload:', validationError.message);
    trackLatencyAndAudit('route_rejected', { ...routingPayload, reason: validationError.message });
    // Safe route iteration: fallback to queue
    await fallbackToQueueRouting(event.queueId);
  }
}

function calculateSeverity(metadata) {
  const baseScore = metadata.baseSeverity || 1;
  const slaMultiplier = metadata.slaBreaching ? 2.5 : 1.0;
  const tierMultiplier = metadata.customerTier === 'enterprise' ? 1.8 : 1.0;
  return Math.round(baseScore * slaMultiplier * tierMultiplier);
}

function evaluateOnCallRotation(queueId, severity) {
  // In production, query an on-call schedule API or Genesys Cloud group members
  // This simulates rotation evaluation based on severity thresholds
  const rotationMap = {
    high: 'supervisor_002',
    medium: 'supervisor_003',
    low: 'supervisor_001'
  };
  const level = severity >= 8 ? 'high' : severity >= 5 ? 'medium' : 'low';
  return rotationMap[level];
}

Step 3: Trigger Agent Assist Prompt and Synchronize with ITSM Webhooks

After validation, the router submits the escalation to the Genesys Cloud Agent Assist API to display a supervisor prompt. It simultaneously posts a signal routed webhook to an external ITSM tool for alignment. The webhook payload includes the escalation reference and routing audit data.

const { AgentassistApi } = require('@genesys/cloud-purecloud-sdk');
const axios = require('axios');

const agentassistApi = new AgentassistApi(platformClient);

async function triggerAgentAssistPrompt(payload) {
  // HTTP POST /api/v2/agentassist/prompts
  // Headers: Authorization: Bearer <token>, Content-Type: application/json
  // Request Body: { targetUserId, promptType, content, metadata }
  const promptRequest = {
    targetUserId: payload.forwardDirective.targetUserId,
    promptType: 'supervisor_escalation',
    content: {
      title: 'Supervisor Escalation Required',
      body: `Priority: ${payload.priorityMatrix.severity}. Conversation: ${payload.escalationReference}`,
      actions: [
        { label: 'Accept Escalation', value: 'accept' },
        { label: 'Decline', value: 'decline' }
      ]
    },
    metadata: {
      escalationReference: payload.escalationReference,
      routingReference: payload.routingReference,
      forwardDirective: payload.forwardDirective
    }
  };

  try {
    const response = await agentassistApi.createPrompt(promptRequest);
    console.log('Agent Assist prompt delivered:', response.id);
    return response;
  } catch (error) {
    if (error.status === 429) {
      console.warn('Rate limit 429 encountered on Agent Assist API. Implementing exponential backoff.');
      await new Promise(resolve => setTimeout(resolve, 2000));
      return agentassistApi.createPrompt(promptRequest);
    }
    throw new Error(`Agent Assist prompt failed: ${error.response?.data || error.message}`);
  }
}

async function syncWithITSMWebhook(payload) {
  const itsmEndpoint = process.env.ITSIM_WEBHOOK_URL;
  if (!itsmEndpoint) {
    console.warn('ITSM_WEBHOOK_URL not configured. Skipping ITSM synchronization.');
    return;
  }

  // HTTP POST <ITSIM_WEBHOOK_URL>/signal/routed
  // Headers: Content-Type: application/json, X-Genesys-Signature: <hmac>
  // Request Body: { event: 'escalation_routed', payload, audit: {} }
  const webhookPayload = {
    event: 'escalation_routed',
    timestamp: new Date().toISOString(),
    payload: {
      escalationReference: payload.escalationReference,
      priorityMatrix: payload.priorityMatrix,
      forwardDirective: payload.forwardDirective,
      validationTimestamp: payload.validationTimestamp
    },
    audit: {
      routedBy: 'escalation_router_service',
      severityScore: payload.priorityMatrix.severity,
      targetAgent: payload.forwardDirective.targetUserId
    }
  };

  try {
    await axios.post(itsmEndpoint, webhookPayload, {
      headers: { 'Content-Type': 'application/json' },
      timeout: 5000
    });
    console.log('ITSM webhook synchronized successfully');
  } catch (error) {
    console.error('ITSM webhook synchronization failed:', error.message);
    // Automatic ticket creation trigger for safe route iteration
    await createFallbackTicket(webhookPayload);
  }
}

async function createFallbackTicket(data) {
  const ticketEndpoint = process.env.ITSIM_TICKET_ENDPOINT;
  if (!ticketEndpoint) return;
  
  try {
    await axios.post(`${ticketEndpoint}/create`, {
      subject: `Escalation Routing Failure: ${data.payload.escalationReference}`,
      description: `Routing validation or webhook sync failed. Payload: ${JSON.stringify(data.payload)}`,
      priority: 'high',
      source: 'genesys_escalation_router'
    });
    console.log('Fallback ITSM ticket created for safe route iteration');
  } catch (error) {
    console.error('Fallback ticket creation failed:', error.message);
  }
}

Step 4: Track Routing Latency, Forward Success Rates, and Generate Audit Logs

The router maintains an in-memory metrics collector that tracks routing latency, forward success rates, and generates structured audit logs for assist governance. These metrics support automated Genesys Cloud management and performance optimization.

const fs = require('fs');
const path = require('path');

const metrics = {
  totalRoutes: 0,
  successfulRoutes: 0,
  rejectedRoutes: 0,
  latencies: []
};

function trackLatencyAndAudit(status, data) {
  const startTime = Date.now();
  metrics.totalRoutes++;

  if (status === 'route_success') {
    metrics.successfulRoutes++;
  } else {
    metrics.rejectedRoutes++;
  }

  const latency = Date.now() - startTime;
  metrics.latencies.push(latency);

  const auditEntry = {
    timestamp: new Date().toISOString(),
    status,
    escalationReference: data.escalationReference,
    routingReference: data.routingReference,
    targetUserId: data.forwardDirective?.targetUserId,
    latencyMs: latency,
    successRate: metrics.totalRoutes > 0 ? (metrics.successfulRoutes / metrics.totalRoutes).toFixed(4) : '0.0000',
    avgLatency: metrics.latencies.length > 0 ? (metrics.latencies.reduce((a, b) => a + b, 0) / metrics.latencies.length).toFixed(2) : '0.00'
  };

  const auditLogPath = path.join(__dirname, 'escalation_audit.log');
  fs.appendFileSync(auditLogPath, JSON.stringify(auditEntry) + '\n');
  console.log('Audit log recorded:', auditEntry);
}

function getRoutingMetrics() {
  return {
    ...metrics,
    currentSuccessRate: metrics.totalRoutes > 0 ? (metrics.successfulRoutes / metrics.totalRoutes) : 0,
    averageLatency: metrics.latencies.length > 0 ? metrics.latencies.reduce((a, b) => a + b, 0) / metrics.latencies.length : 0
  };
}

Common Errors & Debugging

Error: HTTP 401 Unauthorized

• What causes it: The OAuth token expired, the client credentials are incorrect, or the required scopes are missing.
• How to fix it: Verify GENESYS_CLIENT_ID and GENESYS_CLIENT_SECRET in your environment. Ensure the OAuth client in the Genesys Cloud admin console includes agentassist:prompt:write, routing:user:view, and userprofile:view. The SDK automatically refreshes tokens, but network restrictions blocking https://login.${REGION}.genesys.cloud/oauth/token will cause repeated 401 responses.
• Code showing the fix: Wrap the SDK login call in a retry loop with exponential backoff if your proxy requires connection warmup.

Error: HTTP 403 Forbidden

• What causes it: The OAuth client lacks permission to access the target user or queue, or the Agent Assist feature is disabled for the organization.
• How to fix it: Navigate to the Genesys Cloud admin console, open the OAuth client configuration, and verify the scope assignments match the API requirements. Confirm that the Agent Assist capability is enabled under Organization Settings.
• Code showing the fix: Add a pre-flight check using usersApi.getUser(userId) before routing. If it returns 403, log the user ID and escalate to queue routing.

Error: HTTP 429 Too Many Requests

• What causes it: The router exceeds Genesys Cloud rate limits for the Agent Assist or Routing APIs, typically during high-volume escalation bursts.
• How to fix it: Implement token bucket rate limiting or exponential backoff. The SDK does not automatically retry 429 responses for all endpoints.
• Code showing the fix: The triggerAgentAssistPrompt function demonstrates a 2-second delay and retry on 429 status codes. For production, replace this with a dedicated rate limiter library like p-limit.

Error: WebSocket Format Verification Failed

• What causes it: The real-time events stream returns malformed JSON or missing required fields due to platform updates or network fragmentation.
• How to fix it: Validate the message structure before processing. The validateWebSocketFormat function checks for type, data, and timestamp fields.
• Code showing the fix: Wrap JSON.parse(data.toString()) in a try-catch block. Log malformed payloads to a separate error log for platform team review.
