Hi @henry lau 

Good question.

You may first have to use another Zap app that can extract data from the PDF before sending that data to ChatGPT.

e.g. PDF.co: https://zapier.com/apps/pdfco/integrations#triggers-and-actions

Thanks.
I add a step before ChatGPT, in order to get the text file from PDF, before transfer text data to ChatGPT
There are still problem to get text file from PDF. My procedures are:-
 

1. Add  1 step “PDF to Anything Converter” in PDF.co before ChatGPT.
   1. In the step “PDF to Anything Converter in PDF”
      2.1 Account: PDF.co selected. OK
      2.2 Action: 
      2.2.1 Output format (required)
                Plain text with layout, supports scanned PDFs
   2. 2.2 Source PDF URL (Required)
           Select Gmail
           Message URL: http//mail.go…..
      2.2.3 Page selection(Optional) - empty.
      2.2.4 Output file name (Optioned - empty
      
      The result is error.
      
      I suspect that I cannot find the URL of attachment, it may not be Message URL: 
      Do you know what is the right one to the Attachment address?
      
      Thanks a lot!

We would need to see detailed screenshots with how your Zap steps are configured to have true context.

Very useful. Thank you.
