1.2 Integration Patterns¶

1. API-Based Integration (Synchronous)

Agent Desktop ──HTTP Request──► API Gateway ──► Business System
              ◄──Response─────
              (< 2 seconds)

2. Webhook-Based Integration (Asynchronous)

Contact Center Event ──► Webhook ──► Middleware ──► Business System
(Call ends, wrap-up)              (Process)        (Update records)

3. File-Based Integration (Batch)

Contact Center ──► SFTP/S3 ──► ETL Process ──► Data Warehouse
(Nightly reports)           (Transform)       (Analytics)

2. CRM Integration¶

2.1 Salesforce Integration¶

Architecture:

┌──────────────────────────────────────────────────────┐
│            SALESFORCE ENVIRONMENT                    │
│  ┌────────────────────────────────────────────────┐ │

│  └────────────────────────────────────────────────┘ │
└─────────────────────┬────────────────────────────────┘
                      │
                      │ Salesforce API (REST/SOAP)
                      │ OAuth 2.0 Authentication
                      │
┌─────────────────────▼────────────────────────────────┐
│        WEBEX CONTACT CENTER PLATFORM                 │
│  ┌────────────────────────────────────────────────┐ │
│  │  Salesforce Connector (Pre-built)              │ │
│  │  ├─ Screen Pop (ANI/Account lookup)            │ │
│  │  ├─ Click-to-Dial                              │ │
│  │  ├─ Activity Logging                           │ │
│  │  └─ Case Creation                              │ │
│  └────────────────────────────────────────────────┘ │
└──────────────────────────────────────────────────────┘

Key Features:

Screen Pop Workflow:

1. Call arrives at agent
   ↓
2. Extract ANI (caller phone number)
   ↓
3. Query Salesforce: Search Phone field in Contact/Lead/Account
   ↓
4. Match found?
   ├─ Yes → Open Contact/Account record in Salesforce
   │        Display: Name, Account, Recent Cases
   └─ No  → Open "New Contact" form with pre-populated ANI

Click-to-Dial:

Agent clicks phone number in Salesforce
   ↓
Salesforce triggers API call to Webex
   ↓
Webex initiates outbound call to agent
   ↓
Agent answers, call connects to customer
   ↓
Call details automatically logged to Salesforce Activity

Activity Logging (Automatic):

Call Activity Record:
  Type: "Call"
  Subject: "Inbound Call - Customer Support"
  Status: "Completed"
  Duration: "00:05:32"
  Description: "Customer inquiry about billing"
  Related To: Account (ABC Corp)
  Call Direction: "Inbound"
  Wrap-up Code: "Billing - Payment Issue"
  Recorded: Link to call recording
  Timestamp: 2024-10-15 14:32:00

Configuration Steps:

Salesforce Connected App Setup:

Create Connected App in Salesforce:
├─ API Name: "WebexContactCenter"
├─ OAuth Scopes: full, api, refresh_token
├─ Callback URL: https://portal.wxcc.webex.com/callback
└─ Consumer Key & Secret: Save for Webex configuration

Webex Control Hub Configuration:

Navigate to: Control Hub → Contact Center → Integrations
├─ Add Integration: Salesforce
├─ Enter Consumer Key & Secret
├─ Authorize: OAuth flow with Salesforce admin credentials
├─ Field Mapping:
│   ├─ ANI → Contact.Phone
│   ├─ Email → Contact.Email
│   └─ Account Number → Account.AccountNumber
└─ Enable Features:
    ├─ Screen Pop ✅
    ├─ Click-to-Dial ✅
    ├─ Activity Logging ✅
    └─ Case Creation ✅

                      │ Azure AD Authentication
                      │
┌─────────────────────▼────────────────────────────────┐
│        WEBEX CONTACT CENTER + MIDDLEWARE             │
│  ┌────────────────────────────────────────────────┐ │
│  │  Custom Integration (via Azure Logic Apps)    │ │
│  │  ├─ Contact lookup and screen pop              │ │
│  │  ├─ Activity sync (calls, chats)               │ │
│  │  └─ Case auto-creation                         │ │
│  └────────────────────────────────────────────────┘ │
└──────────────────────────────────────────────────────┘

Integration Features:

Feature	Implementation Method
Screen Pop	Webex API + Dynamics Dataverse API
Click-to-Dial	Custom ribbon button + Webex dial API
Activity Logging	Webhook → Azure Logic App → Dynamics
Presence Sync	Real-time agent status sync

Sample Azure Logic App Flow:

Trigger: HTTP Webhook from Webex (Call ended)
   ↓
Parse JSON: Extract call details
   ↓
Condition: Is contact found in Dynamics?
   ├─ Yes → Update existing contact activity
   └─ No  → Create new contact + activity
        ↓
Response: Success/Failure to Webex

2.3 ServiceNow Integration¶

Use Case: Automated Ticket Creation

Customer calls support
   ↓
Agent identifies issue requires ticket
   ↓
Agent clicks "Create Incident" in desktop
   ↓
Webex sends data to ServiceNow API:
├─ Caller: John Doe (john.doe@email.com)
├─ Phone: +1-XX5-0100
├─ Issue: "Application login failure"
├─ Priority: Medium
├─ Assignment Group: Application Support
└─ Notes: Call transcript summary
   ↓
ServiceNow creates Incident: INC0010123
   ↓
Incident number returned to agent desktop
   ↓
Agent provides incident number to customer

API Integration Code Example:

// Webex desktop script to create ServiceNow incident
async function createServiceNowIncident(contactData) {
  const endpoint = 'https://instance.service-now.com/api/now/table/incident';
  const auth = 'Basic ' + btoa('username:password');

  const incidentData = {
    caller_id: contactData.customerId,
    short_description: contactData.issue,
    description: contactData.notes,
    urgency: contactData.priority,
    category: 'inquiry',
    contact_type: 'phone'
  };

  const response = await fetch(endpoint, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': auth
    },
    body: JSON.stringify(incidentData)
  });

  const result = await response.json();
  return result.result.number; // Returns: INC0010123
}

3. Workforce Management Integration¶

3.1 Nice IEX Integration¶

Data Exchange:

Webex Contact Center ──► Nice IEX

    ];

    var tableSchema = {
      id: "webexCCStats",
      alias: "Webex Contact Center Statistics",
      columns: cols
    };

    schemaCallback([tableSchema]);
  };

  myConnector.getData = function(table, doneCallback) {
    // Fetch data from Webex API
    fetch('https://api.wxcc.webex.com/v1/reports/daily-stats', {
      headers: { 'Authorization': 'Bearer ' + tableau.password }
    })
    .then(response => response.json())
    .then(data => {
      table.appendRows(data.results);
      doneCallback();
    });
  };

  tableau.registerConnector(myConnector);
})();

4.2 Power BI Integration¶

DirectQuery Configuration:

Power BI Desktop
   ├─ Get Data → Web
   ├─ Enter Webex API endpoint
   ├─ Authentication: OAuth 2.0
   ├─ Transform Data (Power Query):
   │   ├─ Filter columns
   │   ├─ Change data types
   │   └─ Create calculated columns
   └─ Publish to Power BI Service

Sample M Query (Power Query):

let
    Source = Web.Contents("https://api.wxcc.webex.com/v1/reports/queue-stats",
        [Headers=[Authorization="Bearer " & AccessToken]]),
    JsonData = Json.Document(Source),
    ConvertedToTable = Table.FromRecords(JsonData[data]),
    ChangedType = Table.TransformColumnTypes(ConvertedToTable,{
        {"timestamp", type datetime},
        {"calls_offered", Int64.Type},
        {"calls_handled", Int64.Type},
        {"service_level", Percentage.Type}
    })
in
    ChangedType

5. Custom API Integrations¶

5.1 REST API Authentication¶

OAuth 2.0 Flow:

1. Register Application:
   ├─ Navigate to: developer.webex.com
   ├─ Create Integration
   ├─ Obtain: Client ID & Client Secret
   └─ Set Redirect URI

2. Authorization Request:
   GET https://webexapis.com/v1/authorize
   ?client_id={YOUR_CLIENT_ID}
   &response_type=code
   &redirect_uri={YOUR_REDIRECT_URI}
   &scope=analytics:read_all contact-center:admin_read

3. Exchange Code for Token:
   POST https://webexapis.com/v1/access_token
   {
     "grant_type": "authorization_code",
     "client_id": "{YOUR_CLIENT_ID}",
     "client_secret": "{YOUR_CLIENT_SECRET}",
     "code": "{AUTHORIZATION_CODE}",
     "redirect_uri": "{YOUR_REDIRECT_URI}"
   }

4. Response (Access Token):
   {
     "access_token": "ZmFkNj...",
     "expires_in": 14400,
     "refresh_token": "MGEyN...",
     "token_type": "Bearer"
   }

5. API Requests:
   GET https://api.wxcc.webex.com/v1/reports/...
   Header: Authorization: Bearer {ACCESS_TOKEN}

5.2 Webhook Configuration¶

Event Subscription:

{
  "name": "Call Ended Webhook",
  "targetUrl": "https://your-server.com/webhook/call-ended",
  "resource": "telephony_calls",
  "event": "ended",
  "filter": "queueId=5f8a2b3c4d5e6f7g8h9i0j1k",
  "secret": "your-webhook-secret-for-validation"
}

Webhook Payload Example:

{
  "id": "webhook-event-123",
  "name": "Call Ended Webhook",
  "resource": "telephony_calls",
  "event": "ended",
  "data": {
    "id": "call-abc-123",
    "orgId": "org-xyz-789",
    "sessionId": "session-def-456",
    "callType": "inbound",
    "ani": "+15550100",
    "dnis": "+18005550200",
    "queueId": "queue-123",
    "agentId": "agent-456",
    "startTime": "2024-10-15T14:30:00Z",
    "endTime": "2024-10-15T14:35:32Z",
    "duration": 332,
    "wrapUpCode": "billing-payment-issue",
    "recordingUrl": "https://recordings.wxcc.webex.com/rec-789"
  },
  "created": "2024-10-15T14:35:33Z"
}

Webhook Handler (Node.js Example):

const express = require('express');
const crypto = require('crypto');

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

// Webhook secret for validation
const WEBHOOK_SECRET = 'your-webhook-secret';

app.post('/webhook/call-ended', (req, res) => {
  // Validate webhook signature
  const signature = req.headers['x-webex-signature'];
  const payload = JSON.stringify(req.body);
  const hmac = crypto.createHmac('sha256', WEBHOOK_SECRET);
  const digest = hmac.update(payload).digest('hex');

  if (signature !== digest) {
    return res.status(401).send('Invalid signature');
  }

  // Process webhook data
  const callData = req.body.data;

  // Example: Send to your CRM
  await updateCRM({
    contactPhone: callData.ani,
    callDuration: callData.duration,
    wrapUpCode: callData.wrapUpCode,
    recordingUrl: callData.recordingUrl
  });

  res.status(200).send('Webhook processed');
});

app.listen(3000);

6. Integration Security¶

6.1 Security Best Practices¶

API Security:

Security Layer	Implementation
Authentication	OAuth 2.0 with refresh tokens
Authorization	Scope-based permissions (least privilege)
Encryption	TLS 1.2+ for all API calls
API Keys	Rotate every 90 days
IP Whitelisting	Restrict API access to known IPs
Rate Limiting	100 requests/minute per token
Secrets Management	Azure Key Vault / AWS Secrets Manager

Webhook Security:

Security Measures:
├─ HMAC signature validation (SHA-256)
├─ HTTPS-only endpoints (TLS 1.2+)
├─ IP whitelisting for Webex webhook sources
├─ Idempotency keys to prevent duplicate processing
└─ Webhook secret rotation every 90 days

6.2 Data Privacy and Compliance¶

PII Handling:

Data Classification:
├─ Public: Queue names, system IDs
├─ Internal: Agent names, call statistics
├─ Confidential: Customer phone numbers, recordings
└─ Highly Restricted: Payment card data (PCI-DSS)

Data Masking Rules:
├─ Phone Numbers: Display last 4 digits only in logs
├─ Email: Mask domain (j***@email.com)
├─ Credit Cards: Never store, only tokenized references
└─ Social Security: Never transmitted via API

Compliance Requirements:

Regulation	Requirement	Implementation
GDPR	Right to deletion	API endpoint to purge customer data
CCPA	Data access request	Export customer interaction history
PCI-DSS	Secure payment data	Recording pause during payment
HIPAA	PHI protection	Encryption + access controls

7. Integration Monitoring¶

7.1 Health Check Endpoints¶

API Health Monitoring:

// Monitor Salesforce integration health
async function checkSalesforceHealth() {
  try {
    const response = await fetch('https://api.salesforce.com/services/data/v57.0/', {
      headers: { 'Authorization': 'Bearer ' + sfToken }
    });

    if (response.ok) {
      return { status: 'healthy', latency: response.time };
    } else {
      return { status: 'degraded', error: response.statusText };
    }
  } catch (error) {
    return { status: 'down', error: error.message };
  }
}

Monitoring Dashboard:

┌─────────────────────────────────────────────────────┐
│         INTEGRATION HEALTH DASHBOARD                │
├─────────────────────────────────────────────────────┤
│  Integration    │ Status  │ Latency │ Last Error    │

│  Nice IEX       │ ✅ Up   │   89ms  │ None          │
│  ServiceNow     │ ⚠️ Slow │  2.3s   │ Timeout (1hr) │
│  Tableau        │ ✅ Up   │  234ms  │ None          │
└─────────────────────────────────────────────────────┘

7.2 Error Handling and Retry Logic¶

Retry Strategy:

import time
from retrying import retry

@retry(
    stop_max_attempt_number=3,
    wait_exponential_multiplier=1000,
    wait_exponential_max=10000
)
def call_external_api(url, data):
    """
    Retry logic with exponential backoff:
    - Attempt 1: Immediate
    - Attempt 2: Wait 1 second
    - Attempt 3: Wait 2 seconds
    - Give up after 3 attempts
    """
    response = requests.post(url, json=data, timeout=5)
    response.raise_for_status()
    return response.json()

# Usage
try:
    result = call_external_api(crm_endpoint, customer_data)
except Exception as e:
    log_error(f"API call failed after 3 retries: {e}")
    # Fallback: Queue for manual processing
    queue_for_retry(customer_data)

Circuit Breaker Pattern:

Normal State → API calls succeed
    ↓
Error Threshold Exceeded (5 failures in 1 minute)
    ↓
Open Circuit → Block all API calls for 30 seconds
    ↓
After 30 seconds → Half-Open State
    ↓
Test with 1 API call
    ├─ Success → Close Circuit (resume normal)
    └─ Failure → Open Circuit again (wait 60 seconds)

8. Integration Testing¶

8.1 Test Scenarios¶

Functional Testing:

☐ Screen pop displays correct customer information
☐ Click-to-dial initiates call successfully
☐ Activity logging creates records in CRM
☐ Webhook delivers events within SLA (< 5 seconds)
☐ API authentication and token refresh works
☐ Error handling gracefully degrades
☐ Data validation prevents invalid payloads

Performance Testing:

Load Test Parameters:
├─ API calls: 100 requests/second
├─ Duration: 1 hour
├─ Expected latency: < 500ms (95th percentile)
└─ Success rate: > 99.5%

Monitoring:
├─ Response time distribution
├─ Error rate
├─ Throughput
└─ Resource utilization

8.2 Integration Runbook¶

Troubleshooting Guide:

Issue	Possible Cause	Resolution
Screen pop not appearing	Authentication expired	Refresh OAuth token
API timeout	Network latency	Check firewall, increase timeout
Webhook not received	Firewall blocking	Whitelist Webex IPs
Data sync failure	Invalid field mapping	Validate field mappings
Duplicate records created	Idempotency missing	Implement deduplication logic
