Configuring API key limits

{
  "rateLimit": 100,
  "monthlyLimit": 10000
}

​

Rate limit exceeded

{
  "error": "Rate limit exceeded",
  "message": "You have exceeded the rate limit of 100 requests per minute. Please try again later.",
  "retryAfter": 45
}

Best practices

• Implement exponential backoff when receiving 429 responses
• Cache responses where possible to reduce API calls
• Use bulk endpoints (e.g., bulk contact import) instead of individual calls
• Monitor the X-RateLimit-Remaining header to throttle proactively
