Rate Limits

DiffHook enforces rate limits on API requests to ensure fair usage and system stability. Per-plan quotas govern monitor checks, webhook deliveries, and API calls, with response headers exposing remaining capacity.

Limits

Limits apply per API key and per IP.

Handling 429 responses

When you exceed the limit, you receive 429 Too Many Requests:

Implement exponential backoff when retrying:

async function apiRequest(url, options, retries = 3) {
  const res = await fetch(url, options)
  if (res.status === 429 && retries > 0) {
    const delay = 1000 * (4 - retries)
    await new Promise(r => setTimeout(r, delay))
    return apiRequest(url, options, retries - 1)
  }
  return res
}
