A note about the usertoken in your page: If this is a code page hosted on Quick Base, you don't necessarily need to pass the usertoken since the API will authenticate using the browser's session. Of course, that assumes the user has sufficient access to create records in the table being posted to. Regardless, anyone who can access that page can read that usertoken and then use it to make their own API calls against your application. I'd be very careful about using usertokens in this manner unless absolutely necessary and you know you have rock solid access control to that page.
Yes, you can use this syntax. Just take as many slices of the salami off as you like I prefer to use formula variables for the URLs and then drop them into this syntax.
