API Based Quota Policy - Apinizer Dokümantasyonu

General Information

Policy Type

policy-api-based-quota

Description

API Based Quota policy limits the total number of requests that can be made within a specified time interval (hour, day, or month). Unlike throttling which limits rate, quota limits the total count. It uses a variable (such as API key, user ID, or IP address) to identify and track quota usage for individual clients.

Endpoints

Notes and Warnings

Cache Dependency: This policy requires a cache connection. Ensure cache is properly configured.
Quota vs Throttling:
- Quota limits total count (e.g., 10,000 requests per day)
- Throttling limits rate (e.g., 100 requests per minute)
Identity Variable: Choose the identity variable carefully. Common choices:
- HEADER with API key header - For API key-based quota
- CONTEXT with CLIENT_IP - For IP-based quota
- PARAMETER with user ID - For user-based quota
Quota Intervals:
- ONE_HOUR - Hourly quota (resets every hour)
- ONE_DAY - Daily quota (resets every day)
- ONE_MONTH - Monthly quota (resets every month)
Window Types:
- FIXED - Fixed time windows (e.g., day 1: 00:00-23:59)
- SLIDING - Sliding time windows (last 24 hours from current time)
Detail List: Use detailList to provide different quotas for specific values (e.g., VIP users)
Quota Statistics Headers: When showRateLimitStatisticsInResponseHeader is true, response includes:
- X-RateLimit-Limit - Maximum requests allowed
- X-RateLimit-Remaining - Remaining requests in current window
- X-RateLimit-Reset - Time when quota resets
Cache Error Handling:
- FAIL - Request fails if cache is unavailable (recommended for strict quota enforcement)
- CONTINUE - Request continues if cache is unavailable (quota not enforced)
Deployment: Policy changes require deployment to take effect. Set deploy: true or deploy manually.
