WHMCS Stripe gateway init JavaScript variable value change dynamically

[Corner]

Hello,
I need to change WHMCS stripe gateway init JavaScript variable(See attached) in checkout page without reload page.
If I reload the checkout page , JavaScript variable then have correct value, but I need that option without checkout page  refresh.

Can you clarify which init variable you mean - Do you mean the stripe public key?

This will be set based on the order value, can you provide further details on why you need to change this?

Hi Dan,

I understand that this will be set based on the order value.

Basically I'm trying to develop a One Page Cart for my company. What I'm trying to do is I'm trying to land directly to the Cart Checkout Page for example https://whmcs.url/cart.php?a=checkout where I do not have anything in my cart initially and I see all the products in this page and once I add a product to my cart and checkout using Stripe Demo Card, it does not make the payment but places the order and takes me to unpaid invoice.

But if I come to https://whmcs.url/cart.php?a=checkout by adding a product from https://whmcs.url/cart.php and checks out then I see successful payment and paid invoice.
