Understand rate limits and how to increase them when using the isend.ai API.The isend.ai API uses response headers to indicate your current rate limit status, following the IETF standard:
| Header name | Description |
|---|---|
ratelimit-limit | Maximum number of requests allowed within a window. |
ratelimit-remaining | How many requests you have left within the current window. |
ratelimit-reset | How many seconds until the limits are reset. |
retry-after | How many seconds you should wait before making a follow-up request. |
429 response error. To review these events, filter for status 429 in your isend.ai logs.
Tips to Avoid Rate Limits
- Implement a queueing system for API calls.
- Throttle or stagger requests to prevent bursts.
- Avoid sending requests concurrently unless necessary.
- Monitor your usage through headers in API responses.
