Webhooks
Overview
[If your API supports webhooks, document them here]
Webhook endpoint requirements:
- Must accept POST requests
- Must respond with 200 status within 5 seconds
- Must use HTTPS
Available Events
| Event | Description | Triggered When |
|---|---|---|
[resource].created |
[Resource] was created | New [resource] is created |
[resource].updated |
[Resource] was updated | [Resource] is modified |
[resource].deleted |
[Resource] was deleted | [Resource] is deleted |
Webhook Payload
{
"event": "[resource].created",
"timestamp": "2024-01-16T15:30:00Z",
"data": {
"id": "usr_123abc",
"name": "John Doe",
"email": "john@example.com"
}
}Verifying Webhooks
[Explain how to verify webhook authenticity, e.g., signature verification]
SDK Examples
JavaScript/TypeScript
// Install: npm install @example/api-client
import { APIClient } from '@example/api-client';
const client = new APIClient({
apiKey: 'YOUR_API_TOKEN'
});
// List resources
const users = await client.users.list({
page: 1,
limit: 10
});
// Get single resource
const user = await client.users.get('usr_123abc');
// Create resource
const newUser = await client.users.create({
name: 'Alice Johnson',
email: 'alice@example.com'
});
// Update resource
const updatedUser = await client.users.update('usr_123abc', {
role: 'admin'
});
// Delete resource
await client.users.delete('usr_123abc');Python
# Install: pip install example-api-client
from example_api import APIClient
client = APIClient(api_key='YOUR_API_TOKEN')
# List resources
users = client.users.list(page=1, limit=10)
# Get single resource
user = client.users.get('usr_123abc')
# Create resource
new_user = client.users.create(
name='Alice Johnson',
email='alice@example.com'
)
# Update resource
updated_user = client.users.update(
'usr_123abc',
role='admin'
)
# Delete resource
client.users.delete('usr_123abc')Best Practices
Pagination
Always paginate list endpoints to avoid performance issues:
- Use
limitparameter to control page size - Don't request more than 100 items per page
- Use
pageparameter for subsequent pages
Error Handling
Implement proper error handling:
try {
const user = await client.users.get('usr_123abc');
} catch (error) {
if (error.code === 'NOT_FOUND') {
console.log('User not found');
} else if (error.code === 'UNAUTHORIZED') {
console.log('Authentication failed');
} else {
console.log('Unexpected error:', error.message);
}
}Rate Limiting
Monitor rate limit headers and implement backoff:
const response = await fetch(url, options);
const remaining = response.headers.get('X-RateLimit-Remaining');
if (remaining < 10) {
console.warn('Approaching rate limit');
