This is great! One question I have is with a multiple choice selection on the form. It's pulling in the answer, but not adding the question as a column header, but it's also putting the question a column over each answer that comes through. So it'll go in the right row, but gets pushed a column to the right. Any way to resolve this?

Thanks a lot.

Thank a lot.
I just have a question. How do you generate a Key for this webhook to use in Ads?
