Is there a way for me to exclude the expiration time on the pdfURL so it doesn’t expire?

No, because the pdfURL expires after one hour it cannot be excluded. If you’d like to reference the PDF after this expiration time, then you’ll need to instead reference the GoFormz URL with the Form ID. You’ll format this as:

https://app.goformz.com/forms/`[formId]`

https://app.goformz.com/forms/[formId]. The person selecting this would need to login to goformz account to view.
