Troubleshooting: Zapier failing to send prompts to ChatGPT
My Zap intermittently returns 502/timeout errors when calling the ChatGPT API to draft support replies; need debug steps for retries, rate limits, and payload size. I'm comfortable with basic API logs.

Checklist to debug intermittent 502/timeouts calling ChatGPT from Zapier:
- Add exponential backoff with jitter (3–5 retries: 500ms→1s→2s).
- On 429, honor Retry-After and throttle concurrent zaps (token bucket or queue).
- Reduce payload: trim system/context, shorten examples, lower max_tokens, or batch requests.
- Log request size, latency, response body and headers for each failure.
- In Zapier, increase webhook timeout and enable task retries.
