Hello,
I am able to create a proof with a link instead of file from UI. But I cannot see such functionality in API. I tried to do a POST request to /sheets/{sheetId}/proofs/{proofId}/attachments with the same JSON body like for adding URL to a row but with no luck - "errorCode" : 1011, "message" : "A required header was missing or invalid: Content-Disposition".
Is it possible to attach an URL to a proof, or create a proof with a link?
Thanks,
Michael
