XF 1.4 Dynamic "upgrade" link?

[Okenyon]

I have a custom setup whereby we send our users to an external html page for an upgrade.

Once the "upgrade" link is clicked they are taken to the upgrade page on xenforo and then redirected to click bank to pay and upgrade.

Ideally i'd like to "cut out" the upgrade page on xenforo.

Is there any way I can insert a dynamic link on the external landing page that passes the user information and goes straight to payment?

What you can do is create a small add-on for XenForo that will cough out the form fields that is generated in the Account Upgrade page. Implement a fetcher that will fetch those data through HTTP and put it in that external page.
