Watch out for

VAPI.ai latency can cause awkward pauses in conversation, so optimize your prompt for concise responses to keep the flow natural.
GoHighLevel webhooks may fail silently if payload structures change, add error handling nodes to log and alert on failed triggers.
LLM hallucinations might misclassify a low-quality lead as high-value, implement a confidence threshold check before proceeding to calls.
API rate limits from OpenAI or VAPI can interrupt the workflow, add retry logic with exponential backoff to handle transient errors.
