As I can make a Webhook of this page

What happens is that already and I tried all ways to send data to a spreadsheet and as much as I draw on examples do not work either one or the other thing the last example to make was this but it turned out that the Photon can not open https, so I got to ententer can only be done with a WebHooks.
But I have no idea how to make one and what comes intenete but without success and when I try to create one sends me the following error.

why not use IFTTT and go directly to a Google doc?

well what about IFTTT esque efficiency not expected and I try Webhook.
