I have worked with PayPal NVP many times in the past, and it appears that the REST behaves similarly (just a lot easier). Here is the workflow we are trying to accomplish https://www.screencast.com/t/VNczidWSlyc Basically, we need to have the user: log into PayPal on the Cart Review Page. We receive the customer information (name and shipping address) The user is taken to the Order Confirmation Page, where we add Sales Tax We Settle the Payment for the total amount (Order + Shipping + Tax) In BrainTree, they provided a Nonce that we would receive this, and then we use the Nonce to complete the transaction. In my experience prior, the whole payment process was a single flow that couldn't be broken. We are looking at a hybrid of Client and Server side development on this, as we can pass values back to the server without an issue. I just wanted to make sure this flow is something that is possible. It appears that based on this: https://developer.paypal.com/docs/integration/direct/express-checkout/integration-jsv4/ I can probably hijack that Order Confirmation page to do what I am looking to dp Thanks
