Rate Limits

This guide explains the rate limits and quotas for WhatsAble APIs.

​
Overview

Rate limits are applied to protect our API infrastructure and ensure fair usage. Each API solution has different rate limits based on your plan.

​
Rate Limit Headers

All API responses include rate limit headers: 
X-RateLimit-Limit: 100
X-RateLimit-Remaining: 95
X-RateLimit-Reset: 1616544000

Handling Rate Limits

When you hit a rate limit, you’ll receive a 429 Too Many Requests response: 
{
  "error": {
    "code": "rate_limit_exceeded",
    "message": "Rate limit exceeded. Try again in 60 seconds."
  }
}

​
Best Practices

  1. Implement Exponential Backoff
async function sendWithRetry(url, data, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      const response = await fetch(url, {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
          'Authorization': 'Bearer YOUR_TOKEN'
        },
        body: JSON.stringify(data)
      });

      if (response.status === 429) {
        const retryAfter = response.headers.get('Retry-After') || 60;
        await new Promise(resolve => setTimeout(resolve, retryAfter * 1000));
        continue;
      }

      return await response.json();
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      await new Promise(resolve => setTimeout(resolve, Math.pow(2, i) * 1000));
    }
  }
}
  1. Monitor Usage
    • Track remaining quota
    • Set up alerts for low quota
    • Monitor rate limit headers
  2. Optimize Requests
    • Batch messages when possible
    • Cache responses
    • Use webhooks for status updates
