Answer 1

This describes it:
A basic Express Checkout integration assumes that you are sending the
API calls from your own server using a <form> or <a>.
Essentially, your existing call to SetExpressCheckout (that would obtain a Paypal token) that you use to redirect (in the "standard" Paypal Express Checkout flow).
The linked sample should hopefully clear things up - you'll see the form action (and a link) POST (GET for the a) to some server implementation (the ip address in the sample) of SetExpressCheckout.
Hth..

I can help you with single page PayPal pay now button actually I use this one of my projects
<script src="https://www.paypal.com/sdk/js?client-id=XXXXXXXXXXXXXXXXX">
</script>
<div id="paypal-button-container"> </div>
<script>
paypal.Buttons({
createOrder: function(data, actions) {
return actions.order.create({
purchase_units: [{
amount: {
value: '1230'
}
}]
});
},
onApprove: function(data, actions) {
return actions.order.capture().then(function(details) {
alert('Transaction completed');
// Call your server to save the transaction
return fetch('codes/paypalapi.php?invo=123', {
method: 'post',
headers: {
'content-type': 'application/json'
},
body: JSON.stringify({
orderID: data.orderID,
amount: data.amount
})
});
});
}
}).render('#paypal-button-container');
</script>
change codes/paypalapi.php?invo=123 with your callback url
