(I worked on Checkout)

You can! The docs on our custom integration are here: https://stripe.com/docs/checkout#integration-custom

I stand corrected.

Does this allow you to change the price dynamically though?

For example, if the user selects Canada for their billing address I must then add the appropriate taxes to the price dynamically. Doesn't seem like that is possible?

I'm afraid we don't support that use-case yet. If you'd still like to use Checkout, you could use it as a method for the user to add their card, and confirm the payment amount on a separate page. (the 'amount' field is not required)

Thanks. The form is very slick so just using it to collect the information is not half bad.
