Webhook Payload

{
  "id": "abc123xyz",
  "status": "completed",
  "url": "https://cdn.doitong.com/outputs/abc123xyz.mp3",
  "service": "hedra",
  "createdAt": "2024-01-01T00:00:00Z",

Best Practices

1. Optimize Your Prompts

Write clear, descriptive prompts for best results:

• Be specific about visual elements, style, and mood
• Include details about lighting, camera angles, and composition
• Avoid contradictory or impossible requests

2. Handle Async Processing

Generation is asynchronous. Implement proper polling or webhooks:

// Polling example
async function pollStatus(jobId) {
  let status = 'processing';
  while (status === 'processing') {
    await sleep(2000); // Wait 2 seconds
    const result = await checkJobStatus(jobId);
    status = result.status;
  }
  return result;
}

3. Error Recovery

Implement retry logic with exponential backoff:

async function retryWithBackoff(fn, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await fn();
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      await sleep(Math.pow(2, i) * 1000);
    }
  }
}

4. Monitor Credit Usage

Track your credit consumption to avoid interruptions:

• Check credit balance before large batch operations
• Set up alerts for low credit thresholds
• Implement credit-aware request queuing
