Hi @yingx5536 This is one of the integrations I’m not most familiar with, but I’ve asked our tech team about it. I’ll post back here when they've responded!

Try this: Use the built in data function on PA called “Parse JSON” and insert “Body”. That will retrieve all fields including hidden ones.

Thanks for your input, @Brent Davidoff yes, it works with “Parse Json”. Found the steps in another post. 

Still hope typeform can include hidden field in the variables so we can skip the additional steps when doing “Parse Json”. 

Ah you and me both @yingx5536 !

Ah, thank you, @Brent Davidoff !!
