Managing Genesys Cloud User Profile Metadata with Node.js

What You Will Build

This tutorial delivers a production-ready Node.js module that retrieves user profiles, updates custom attributes with schema validation, uploads avatars with size enforcement, manages presence TTLs, registers outbound webhooks for HR synchronization, and extracts audit logs for compliance. You will use the Genesys Cloud CX REST API and the official @genesyscloud/api-client SDK. The implementation runs on modern Node.js (v18+) using native fetch and async/await.

Prerequisites

• Genesys Cloud OAuth 2.0 Client Credentials grant with scopes: user:view, user:write, presence:write, auditlog:view, integration:write
• Genesys Cloud API version: v2
• Node.js runtime: v18.0.0 or higher
• External dependencies: @genesyscloud/api-client, express, zod, axios
• Environment variables: GENESYS_ORGANIZATION_ID, GENESYS_CLIENT_ID, GENESYS_CLIENT_SECRET, GENESYS_REGION

Authentication Setup

Genesys Cloud uses OAuth 2.0 Client Credentials for server-to-server integrations. You must request a token from the regional login endpoint, cache it, and refresh it before expiration. The following helper handles token acquisition, caching, and automatic retry on 429 rate limits.

import https from 'https';
import crypto from 'crypto';

const TOKEN_CACHE = new Map();
const REGION_ENDPOINTS = {
  'us-east-1': 'https://login.us-east-1.mypurecloud.com',
  'us-east-2': 'https://login.us-east-2.mypurecloud.com',
  'eu-west-1': 'https://login.eu-west-1.mypurecloud.com',
  'ap-southeast-2': 'https://login.ap-southeast-2.mypurecloud.com'
};

async function fetchWithRetry(url, options, retries = 3) {
  for (let attempt = 1; attempt <= retries; attempt++) {
    const response = await fetch(url, options);
    if (response.status === 429) {
      const retryAfter = response.headers.get('retry-after') || Math.pow(2, attempt);
      console.log(`Rate limited. Retrying in ${retryAfter}s...`);
      await new Promise(resolve => setTimeout(resolve, retryAfter * 1000));
      continue;
    }
    return response;
  }
  throw new Error('Max retries exceeded for 429 rate limit');
}

export async function getAccessToken(organizationId, clientId, clientSecret, region) {
  const cacheKey = `${organizationId}:${clientId}`;
  const cached = TOKEN_CACHE.get(cacheKey);
  if (cached && cached.expiresAt > Date.now()) {
    return cached.token;
  }

  const baseUrl = REGION_ENDPOINTS[region] || `https://login.${region}.mypurecloud.com`;
  const body = new URLSearchParams({
    grant_type: 'client_credentials',
    client_id: clientId,
    client_secret: clientSecret
  });

  const response = await fetchWithRetry(`${baseUrl}/login/oauth2/v1/token`, {
    method: 'POST',
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
    body
  });

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

  const data = await response.json();
  const expiresAt = Date.now() + (data.expires_in * 1000) - 60000; // Refresh 1 minute early
  TOKEN_CACHE.set(cacheKey, { token: data.access_token, expiresAt });
  return data.access_token;
}

Implementation

Step 1: Query User Profiles and Implement Paginated Search

The Users API returns profile details and supports pagination for bulk queries. You will use the GET /api/v2/users endpoint with pageSize and pageToken parameters. The required scope is user:view.

const GENESYS_BASE = 'https://api.mypurecloud.com';

export async function searchUsers(token, query = {}, page = 1, pageSize = 25) {
  const params = new URLSearchParams({
    'page': String(page),
    'pageSize': String(pageSize),
    ...query
  });

  const response = await fetch(`${GENESYS_BASE}/api/v2/users?${params}`, {
    headers: { 'Authorization': `Bearer ${token}`, 'Accept': 'application/json' }
  });

  if (!response.ok) {
    const errBody = await response.text();
    throw new Error(`User search failed ${response.status}: ${errBody}`);
  }

  const data = await response.json();
  return {
    users: data.entities || [],
    nextPage: data.nextPageToken,
    total: data.total
  };
}

export async function getUserProfile(token, userId) {
  const response = await fetch(`${GENESYS_BASE}/api/v2/users/${userId}`, {
    headers: { 'Authorization': `Bearer ${token}`, 'Accept': 'application/json' }
  });

  if (!response.ok) {
    const errBody = await response.text();
    throw new Error(`Profile fetch failed ${response.status}: ${errBody}`);
  }
  return response.json();
}

Expected response for getUserProfile:

{
  "id": "a1b2c3d4-e5f6-7890-g1h2-i3j4k5l6m7n8",
  "name": "Jane Operator",
  "email": "jane.operator@company.com",
  "attributes": {
    "department": "Support",
    "employeeId": "EMP-8842"
  },
  "division": { "id": "div-001", "name": "Global" }
}

Step 2: Update Custom Attributes with PATCH and Schema Validation

Custom attributes reside in the attributes object of the user payload. You will validate incoming data with zod, then issue a PATCH /api/v2/users/{userId} request. The required scope is user:write.

import { z } from 'zod';

const UserAttributesSchema = z.object({
  department: z.string().min(1).max(100),
  employeeId: z.string().regex(/^[A-Z]{2,4}-\d{4,8}$/),
  costCenter: z.string().optional(),
  managerId: z.string().uuid().optional()
});

export async function updateCustomAttributes(token, userId, newAttributes) {
  const validation = UserAttributesSchema.safeParse(newAttributes);
  if (!validation.success) {
    throw new Error(`Schema validation failed: ${validation.error.message}`);
  }

  const response = await fetch(`${GENESYS_BASE}/api/v2/users/${userId}`, {
    method: 'PATCH',
    headers: {
      'Authorization': `Bearer ${token}`,
      'Content-Type': 'application/json',
      'Accept': 'application/json'
    },
    body: JSON.stringify({ attributes: validation.data })
  });

  if (!response.ok) {
    const errBody = await response.text();
    throw new Error(`Attribute update failed ${response.status}: ${errBody}`);
  }

  return response.json();
}

Step 3: Handle Profile Image Uploads with Base64 Decoding and Size Limits

Genesys Cloud accepts avatar uploads via PUT /api/v2/users/{userId}/avatar using multipart/form-data. The platform enforces a 2MB limit. You will decode a base64 string, enforce the limit, and upload the buffer. The required scope is user:write.

export async function uploadUserProfileImage(token, userId, base64Image) {
  const base64Data = base64Image.replace(/^data:image\/\w+;base64,/, '');
  const buffer = Buffer.from(base64Data, 'base64');
  const MAX_SIZE = 2 * 1024 * 1024; // 2MB

  if (buffer.length > MAX_SIZE) {
    throw new Error(`Avatar exceeds 2MB limit. Received ${(buffer.length / 1024 / 1024).toFixed(2)}MB`);
  }

  const formData = new FormData();
  formData.append('file', new Blob([buffer]), `avatar_${userId}.png`);

  const response = await fetch(`${GENESYS_BASE}/api/v2/users/${userId}/avatar`, {
    method: 'PUT',
    headers: { 'Authorization': `Bearer ${token}` },
    body: formData
  });

  if (!response.ok) {
    const errBody = await response.text();
    throw new Error(`Avatar upload failed ${response.status}: ${errBody}`);
  }

  return { success: true, uploadedBytes: buffer.length };
}

Step 4: Manage User Presence Status with TTL Expiration

Presence updates use PUT /api/v2/presence/users/{userId}/status. You will set an expiresIn duration using ISO 8601 format. The required scope is presence:write.

export async function updatePresenceStatus(token, userId, statusType, expiresIn = 'PT30M') {
  const response = await fetch(`${GENESYS_BASE}/api/v2/presence/users/${userId}/status`, {
    method: 'PUT',
    headers: {
      'Authorization': `Bearer ${token}`,
      'Content-Type': 'application/json',
      'Accept': 'application/json'
    },
    body: JSON.stringify({
      status: { type: statusType },
      expiresIn: expiresIn
    })
  });

  if (!response.ok) {
    const errBody = await response.text();
    throw new Error(`Presence update failed ${response.status}: ${errBody}`);
  }

  return response.json();
}

Step 5: Synchronize Changes via Webhooks and Generate Audit Logs

You will register an outbound webhook for user updates, expose an Express endpoint to receive events, and query the audit log API for compliance records. The webhook registration requires integration:write. Audit log retrieval requires auditlog:view.

import express from 'express';
import axios from 'axios';

const app = express();
app.use(express.json());

// Webhook receiver for HR sync
app.post('/webhooks/genesys/user-updates', async (req, res) => {
  try {
    const { event, entity } = req.body;
    if (event !== 'user.updated') return res.status(200).send('Ignored event');

    // Sync to downstream HR system (mocked)
    await axios.post(process.env.HR_SYNC_ENDPOINT || 'https://hr.internal/api/users/sync', {
      userId: entity.id,
      attributes: entity.attributes,
      timestamp: new Date().toISOString()
    }, { headers: { 'X-Api-Key': process.env.HR_API_KEY } });

    res.status(200).send('Synced');
  } catch (error) {
    console.error('HR sync failed:', error.message);
    res.status(500).send('Sync error');
  }
});

export function startWebhookServer(port = 3000) {
  return new Promise(resolve => {
    app.listen(port, () => {
      console.log(`Webhook listener running on port ${port}`);
      resolve(app);
    });
  });
}

// Audit log retrieval
export async function getUserAuditLogs(token, userId, entityType = 'users') {
  const response = await fetch(`${GENESYS_BASE}/api/v2/auditlogs/${entityType}/${userId}`, {
    headers: { 'Authorization': `Bearer ${token}`, 'Accept': 'application/json' }
  });

  if (!response.ok) {
    const errBody = await response.text();
    throw new Error(`Audit log fetch failed ${response.status}: ${errBody}`);
  }

  const data = await response.json();
  return {
    auditRecords: data.entities || [],
    nextPageToken: data.nextPageToken
  };
}

Complete Working Example

The following script ties all components together. It authenticates, searches users, updates attributes, uploads an avatar, sets presence with TTL, retrieves audit logs, and starts the webhook server. Replace the placeholder credentials before execution.

import { getAccessToken } from './auth.js';
import { searchUsers, getUserProfile, updateCustomAttributes, uploadUserProfileImage, updatePresenceStatus, getUserAuditLogs, startWebhookServer } from './profile-manager.js';

async function main() {
  const orgId = process.env.GENESYS_ORGANIZATION_ID;
  const clientId = process.env.GENESYS_CLIENT_ID;
  const clientSecret = process.env.GENESYS_CLIENT_SECRET;
  const region = process.env.GENESYS_REGION || 'us-east-1';

  if (!orgId || !clientId || !clientSecret) {
    console.error('Missing required environment variables');
    process.exit(1);
  }

  const token = await getAccessToken(orgId, clientId, clientSecret, region);
  console.log('Authenticated successfully');

  // 1. Search for a user
  const searchResult = await searchUsers(token, { name: 'Jane Operator' });
  if (!searchResult.users.length) {
    console.error('No users found matching query');
    return;
  }
  const targetUser = searchResult.users[0];
  console.log(`Found user: ${targetUser.name} (${targetUser.id})`);

  // 2. Update custom attributes
  await updateCustomAttributes(token, targetUser.id, {
    department: 'Premium Support',
    employeeId: 'EMP-9921',
    costCenter: 'CC-404'
  });
  console.log('Custom attributes updated');

  // 3. Upload avatar (simulated base64 PNG header for brevity)
  const mockBase64 = 'iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mNk+M9QDwADhgGAWjR9awAAAABJRU5ErkJggg==';
  await uploadUserProfileImage(token, targetUser.id, `data:image/png;base64,${mockBase64}`);
  console.log('Avatar uploaded');

  // 4. Update presence with 30-minute TTL
  await updatePresenceStatus(token, targetUser.id, 'Available', 'PT30M');
  console.log('Presence status updated with TTL');

  // 5. Retrieve audit logs
  const auditLogs = await getUserAuditLogs(token, targetUser.id);
  console.log(`Retrieved ${auditLogs.auditRecords.length} audit records`);

  // 6. Start webhook server for HR sync
  await startWebhookServer(3000);
  console.log('Webhook server active. Ready for HR synchronization.');
}

main().catch(err => console.error('Fatal error:', err));

Common Errors & Debugging

Error: 401 Unauthorized

• Cause: Expired or invalid OAuth token, incorrect client credentials, or missing Authorization header.
• Fix: Verify environment variables match the Genesys Cloud application settings. Ensure the token caching logic refreshes before expires_in. Check that the Authorization header uses the Bearer prefix exactly.
• Code showing the fix: The getAccessToken function automatically refreshes when Date.now() >= cached.expiresAt. Add a fallback retry loop if the initial token fetch fails.

Error: 403 Forbidden

• Cause: The OAuth client lacks the required scope for the endpoint, or the user ID belongs to a division the client cannot access.
• Fix: Navigate to the Genesys Cloud admin console, open the application, and verify that user:view, user:write, presence:write, auditlog:view, and integration:write are enabled. Confirm the divisionId matches your target environment.
• Code showing the fix: Append divisionId to query parameters when scoping requests to specific divisions.

Error: 429 Too Many Requests

• Cause: Exceeding Genesys Cloud rate limits (typically 30 requests per second per client for standard tiers).
• Fix: Implement exponential backoff. The fetchWithRetry helper in the authentication section demonstrates this pattern. Apply the same wrapper to all fetch calls in production.
• Code showing the fix: Wrap all API calls in fetchWithRetry(url, options, retries). Parse the retry-after header when available.

Error: 400 Bad Request (Schema Validation)

• Cause: Invalid JSON structure, missing required fields, or malformed expiresIn duration string.
• Fix: Validate payloads against the Zod schema before transmission. Ensure expiresIn follows ISO 8601 duration format (PT1H, PT30M, P1D).
• Code showing the fix: The UserAttributesSchema.safeParse() call throws a descriptive error before the HTTP request is made.
