Issue Rivhit receipts from WhatsApp photos using Google Vision and GPT-4o

How it works

1. Courier sends an invoice photo to WhatsApp → AI extracts all details via Google Vision OCR
2. Courier sends a payment photo (check, bank transfer, credit card voucher) → AI matches it to the invoice
3. AI presents a summary and asks for confirmation
4. Once approved — receipt is created in Rivhit, invoice is closed, and the PDF is sent back to WhatsApp

Supports cash, checks, credit cards, bank transfers, and split payments. Includes automatic customer lookup by tax ID and Israeli bank code recognition.

Takes about 10 minutes:

3. Add your Rivhit API token to the "api key" Set node
4. Replace the WhatsApp group ID in the Filter node with yours
5. Connect your OpenAI credentials
6. Activate and start sending photos!
