Integration Workflow

1. Set Up Webhook Endpoints

Configure where Whappy should send event data:

# Configure appointment webhook
curl -X POST https://api.whappy.ai/v1/zap/url/appointment \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your_api_key" \
  -d '{"targetUrl": "https://hooks.zapier.com/hooks/catch/123456/appointment/"}'

# Configure close event webhook
curl -X POST https://api.whappy.ai/v1/zap/url/close \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your_api_key" \
  -d '{"targetUrl": "https://hooks.zapier.com/hooks/catch/123456/close/"}'

2. Test Your Integration

Verify your API connection:

curl -X POST https://api.whappy.ai/v1/zap \
  -H "X-API-Key: your_api_key"

3. Get Sample Data

Understand the data structure you’ll receive:

# Get appointment event sample
curl -X GET https://api.whappy.ai/v1/zap/sample/appointment \
  -H "X-API-Key: your_api_key"

# Get close event sample
curl -X GET https://api.whappy.ai/v1/zap/sample/close \
  -H "X-API-Key: your_api_key"

4. Handle Webhook Data

In your Zapier webhook handler, you’ll receive the DataPayload structure. Parse the JSON fields as needed:

// Example webhook handler (Node.js)
app.post('/webhook/whappy-appointment', (req, res) => {
  const payload = req.body;

  // Parse JSON fields
  const leadInfo = JSON.parse(payload.lead_info_json || '{}');
  const collectedInfo = JSON.parse(payload.collected_info_json || '{}');
  const appointmentInfo = JSON.parse(payload.appointment_json || '{}');

  // Process the data
  console.log('New appointment scheduled:', {
    leadName: payload.name,
    phone: payload.phone,
    appointmentDate: payload.appointment.full_date,
    budget: collectedInfo.budget,
    source: leadInfo.source
  });

  res.status(200).send('OK');
});

Common Use Cases

CRM Integration

Automatically create or update contacts in your CRM:

// Example: Send to HubSpot
const hubspotContact = {
  properties: {
    firstname: payload.name.split(' ')[0],
    lastname: payload.name.split(' ')[1],
    phone: payload.phone,
    lead_source: JSON.parse(payload.lead_info_json).source,
    budget: JSON.parse(payload.collected_info_json).budget
  }
};

Calendar Integration

Add appointments to scheduling systems:

// Example: Create Google Calendar event
const calendarEvent = {
  summary: `Consultation with ${payload.name}`,
  start: {
    dateTime: payload.appointment.full_date,
    timeZone: 'America/New_York'
  },
  description: `Phone: ${payload.phone}\nBudget: ${JSON.parse(payload.collected_info_json).budget}`
};

Email Marketing

Add leads to email sequences:

// Example: Add to Mailchimp list
const subscriber = {
  email_address: JSON.parse(payload.collected_info_json).email,
  status: 'subscribed',
  merge_fields: {
    FNAME: payload.name.split(' ')[0],
    PHONE: payload.phone,
    BUDGET: JSON.parse(payload.collected_info_json).budget
  }
};

Security Best Practices

API Key Management

Store API keys securely using environment variables
Never commit API keys to version control
Rotate API keys periodically
Use different API keys for development and production

Webhook Security

Validate webhook payloads before processing
Use HTTPS endpoints for webhooks
Implement proper error handling and logging
Set up monitoring for webhook failures

Data Handling

Parse JSON fields safely with try-catch blocks
Validate data types before processing
Sanitize data before storing or forwarding
Respect data privacy regulations (GDPR, CCPA)

Testing Your Integration

1. Test API Connection

curl -X POST https://api.whappy.ai/v1/zap \
  -H "X-API-Key: your_test_api_key" \
  -v

2. Configure Test Webhooks

# Use tools like ngrok for local testing
ngrok http 3000

# Configure webhook with ngrok URL
curl -X POST https://api.whappy.ai/v1/zap/url/close \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your_test_api_key" \
  -d '{"targetUrl": "https://abc123.ngrok.io/webhook/close"}'

3. Validate Sample Data

# Get and validate sample data structure
curl -X GET https://api.whappy.ai/v1/zap/sample/close \
  -H "X-API-Key: your_test_api_key" | jq .

4. Monitor Webhook Calls

Set up logging in your webhook handler to monitor incoming data:

app.post('/webhook/test', (req, res) => {
  console.log('Webhook received:', JSON.stringify(req.body, null, 2));
  res.status(200).send('OK');
});
