To address the frequent crashes you're experiencing, let’s consider whether you might be using the Response API or the Chat completion API more effectively.
1. API Choice:
- Response API: Best suited for initiating conversations and obtaining a single response. It uses
/chat/responses as its endpoint.
- Chat Completion API: More suitable for managing ongoing conversations, maintaining context with features like previousChatId.
2. Implementation Tips:
- If your use case involves multi-turn conversations or requires context management, the Chat Completion API is preferable.
- Ensure your API requests are constructed correctly, considering optional parameters like assistantId or stream if real-time feedback is critical.
3. Debugging Steps:
- Check server logs for any error messages when the application crashes.
- Verify that your authentication tokens and API keys are correctly configured in the API requests.
- Consider reviewing any specific error logs or outputs to identify what might be causing the application to crash.
For further improvements or troubleshooting, you might want to test with both APIs to see which aligns more closely with your application's needs.Chat quickstart | Vapi
