Troubleshooting: Zapier webhook to ChatGPT failing on attachments
Zapier webhooks drop emails with attachments or the attachment text isn't passed to ChatGPT; need debugging steps and robust file handling patterns. This is blocking my automation for PDFs and screenshots.

Quick checklist for Zapier→ChatGPT attachments:
1) Confirm your trigger captures attachments (Email by Zapier/IMAP “include attachments”).
2) Inspect Zap task history/raw webhook—attachments should show as file URLs or base64.
3) If you need text from PDFs/screenshots, add an OCR step and pass the OCR text to ChatGPT.
4) Store files in Drive/S3 and send public URLs (or use multipart/form-data file fields) instead of raw binary.
5) Test with webhook.site and sample payloads.
