@shameemreza response from Moneris for Woocommerce below.

We bypass the cart page, where users normally input their shipping address. This is probably where the preload request is originated – after the user inputs their shipping info in the cart page and continues to checkout.

We instead have them input this info on the checkout page. But in the past, inputting or changing this address at checkout has caused the Moneris costs to re-calculate, as if the preload request is re-sent when the address is updated. This doesn’t seem to be happening anymore. Is there any way to force it if an address is changed?

Moneris response:

Hello Rishi,

Thank you for your email. The Moneris Checkout is working as intended, the transaction amount has to be sent in the preload before the form is loaded on the webpage or in a iframe.

The preload is done with the values that are to be displayed on the Checkout form, and a preload is only done once to  generate a ticket which is then used to load the Checkout form in the browser or Iframe.

The Checkout should not be having the preload request sent before those shipping details are confirmed as the Checkout will not update based on you changing the shipping details as a new preload request should have to be sent to create a new instance of Checkout, as this is not a live form, so the details in which you would like to have displayed on the Checkout form need to be sent in the preload request prior to it being displayed in the browser or Iframe.

These are the mandatory values in a preload request
