Best Practices

Pagination

Always use pagination for list endpoints to avoid large response payloads:

const products = await fetch('/api/products?page=1&limit=20')

Error Handling

Always handle API errors gracefully:

try {
  const response = await fetch('/api/products')
  const data = await response.json()
  
  if (!response.ok) {
    throw new Error(data.error.message)
  }
  
  return data
} catch (error) {
  console.error('API Error:', error.message)
  // Handle error appropriately
}

Caching

Implement caching for frequently accessed data:

// Cache products for 5 minutes
const products = await fetch('/api/products', {
  headers: {
    'Cache-Control': 'max-age=300'
  }
})

Bulk Operations

Use bulk endpoints when possible to reduce API calls:

// Instead of multiple single requests
const adjustments = await fetch('/api/inventory/adjustments', {
  method: 'POST',
  body: JSON.stringify({
    adjustments: [
      { product_id: 'prod_1', actual_quantity: 100 },
      { product_id: 'prod_2', actual_quantity: 200 }
    ]
  })
})
## Getting Started

Ready to integrate with our API? Here are some quick examples to get you started:

### Quick Example - Fetch Products
```javascript
const response = await fetch('/api/products?limit=10', {
  headers: {
    'Authorization': 'Bearer YOUR_JWT_TOKEN',
    'Content-Type': 'application/json'
  }
})
const products = await response.json()

Quick Example - Create a Product

curl -X POST "https://your-domain.com/api/products" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Smart Widget",
    "sku": "SW-001",
    "price": 49.99
  }'

Quick Example - Record Inventory Movement

await fetch('/api/inventory/movements', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_JWT_TOKEN',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    product_id: 'prod_123',
    warehouse_id: 'wh_789',
    movement_type: 'in',
    quantity: 50
  })
})
