# Agility CMS & Management API TypeScript SDK

## WebhookMethods

This class provides comprehensive webhook management operations for Agility CMS. Webhooks allow you to receive real-time notifications when specific events occur in your CMS, enabling integration with external systems and automated workflows.

**Important Notes:**
- Webhooks provide real-time event notifications to external endpoints
- Each webhook can be configured to trigger on specific events
- Webhooks support various event types (content changes, page updates, etc.)
- Webhook URLs must be accessible and return appropriate HTTP status codes
- Failed webhook deliveries are automatically retried with exponential backoff
- Webhooks can be secured with authentication headers or signatures

### Function List
- [getWebhook](#getwebhook) - Retrieves a specific webhook by ID
- [webhookList](#webhooklist) - Retrieves list of all webhooks
- [saveWebhook](#savewebhook) - Creates or updates a webhook
- [deleteWebhook](#deletewebhook) - Deletes a webhook by ID

---

console.log('Webhook name:', webhook.name);
console.log('Webhook URL:', webhook.url);
console.log('Events:', webhook.events);
console.log('Active:', webhook.isActive);
console.log('Created:', webhook.createdDate);
console.log('Last triggered:', webhook.lastTriggered);

// Display webhook statistics
if (webhook.statistics) {
    console.log('Statistics:');
    console.log(`  Total deliveries: ${webhook.statistics.totalDeliveries}`);
    console.log(`  Successful deliveries: ${webhook.statistics.successfulDeliveries}`);
    console.log(`  Failed deliveries: ${webhook.statistics.failedDeliveries}`);
    console.log(`  Success rate: ${webhook.statistics.successRate}%`);

    console.log(result); // "Webhook deleted successfully"
} catch (error) {
    console.error('Failed to delete webhook:', error.message);
}

// Safe webhook deletion with confirmation
const safeDeleteWebhook = async (webhookID) => {
    try {
        // Get webhook details first
        const webhook = await apiClient.webhookMethods.getWebhook(webhookID, guid);
        console.log(`About to delete webhook: ${webhook.name}`);
        console.log(`URL: ${webhook.url}`);
        console.log(`Events: ${webhook.events.join(', ')}`);
        
        // Check if webhook is active
        if (webhook.isActive) {
            console.log('Warning: Deleting active webhook');
        }
        
        // Perform deletion
        const result = await apiClient.webhookMethods.deleteWebhook(webhookID, guid);
        console.log('Webhook deleted successfully');
        return result;
    } catch (error) {
        console.error('Failed to delete webhook:', error.message);
        throw error;
    }
};

// Bulk cleanup of inactive webhooks
const cleanupInactiveWebhooks = async () => {
    const webhooks = await apiClient.webhookMethods.getWebhookList(guid);
    const inactiveWebhooks = webhooks.filter(w => !w.isActive);
    
    console.log(`Found ${inactiveWebhooks.length} inactive webhooks`);
    
    for (const webhook of inactiveWebhooks) {
        const shouldDelete = confirm(
            `Delete inactive webhook "${webhook.name}"? (${webhook.url})`
        );
        
        if (shouldDelete) {
            await apiClient.webhookMethods.deleteWebhook(webhook.webhookID, guid);
            console.log(`Deleted webhook: ${webhook.name}`);
        }
    }
};

// Delete webhooks with high failure rates
const cleanupFailingWebhooks = async (maxFailureRate = 50) => {
    const webhooks = await apiClient.webhookMethods.getWebhookList(guid);
    
    const failingWebhooks = webhooks.filter(webhook => 
        webhook.statistics && 
        webhook.statistics.successRate < maxFailureRate &&
        webhook.statistics.totalDeliveries > 10 // Only consider webhooks with sufficient data
    );
    
    console.log(`Found ${failingWebhooks.length} webhooks with high failure rate`);
    
    for (const webhook of failingWebhooks) {
        console.log(`Webhook "${webhook.name}" has ${webhook.statistics.successRate}% success rate`);
        
        const shouldDelete = confirm(
            `Delete failing webhook "${webhook.name}"? (Success rate: ${webhook.statistics.successRate}%)`
        );
        
        if (shouldDelete) {
            await apiClient.webhookMethods.deleteWebhook(webhook.webhookID, guid);
            console.log(`Deleted failing webhook: ${webhook.name}`);
        }
    }
};
```

**Deletion Considerations:**
- Deleting a webhook immediately stops all future event deliveries
- Pending webhook deliveries may still be processed
- Webhook statistics and history are permanently lost
- Consider deactivating instead of deleting for temporary suspension

**Best Practices:**
- Test webhook endpoints before creating webhooks
- Use appropriate authentication to secure webhook endpoints
- Monitor webhook statistics and success rates
- Implement proper error handling in webhook receivers
- Use webhook signatures to verify authenticity
- Set reasonable timeout values to avoid blocking
- Consider implementing idempotency in webhook receivers

**Error Handling:**
- Throws `Exception` when webhook not found
- Throws `Exception` when deletion fails
- Throws `Exception` when insufficient permissions to delete webhooks
