3. **Ensure Tools are Added to the Assistant**: Go to Dashboard > Assistants, and ensure your assistant has the proper GoHighLevel tools added under the Tools tab.
4. **Review System Prompt Setup**: Confirm that your assistant’s system prompt includes precise instructions on using these tools in sequence for booking appointments, as outlined in the setup guide.
5. **Error Handling**: Implement error handling in case the tools do not operate as expected, possibly including retries or fallback messages.
For a detailed setup guide, you can refer to the [GoHighLevel Integration](https://docs.vapi.ai/tools/go-high-level) documentation. If the issue persists, reviewing call logs for specific endedReason codes might help diagnose the cause if related to call handling. For help with specific error codes during calls, you can review the [Call End Reasons](https://docs.vapi.ai/calls/call-ended-reason) documentation.
If this doesn’t resolve the issue, please let us know and we’ll be happy to step in and assist further.Tay
