Best Practices​

  1. Callback Handling

    • Implement robust callback handling for asynchronous tasks.
    • Properly manage different callback stages (e.g., text, first, complete for music generation).
    • Gracefully handle edge cases and errors in callbacks.

  2. Error Handling

    • Implement appropriate error handling based on the status codes.
    • Use retry mechanisms for transient failures (e.g., network issues, temporary server errors).
    • Monitor credit usage regularly to prevent 429 Insufficient Credits errors.

  3. Performance Optimization

    • Efficiently handle streaming audio responses if applicable.
    • Implement reasonable request timeouts.
    • Cache responses where appropriate, respecting data freshness.
    • Use the "Get Details" endpoints to poll for task status instead of solely relying on callbacks if needed.
