Hi there, https://stripe.com/docs/billing/subscriptions/upgrade-downgrade have you got a chance to go through this doc?

I have not, but it looks like exactly what I'm after! Thanks

However in saying that, I still end up on the same Proration page that has me a litle confused (as I want to preview the proration beforehand)..
This is the code in question:

const items = [{
  id: subscription.items.data[0].id,
  price: 'price_CBb6IXqvTLXp3f', // Switch to new price
}];

const invoice = await stripe.invoices.retrieveUpcoming({
  customer: 'cus_4fdAW5ftNQow1a',
  subscription: 'sub_49ty4767H20z6a',
  subscription_items: items,
  subscription_proration_date: proration_date,
});

am I able to pass items like this (pulled from the upgrade and downgrade page):

[
  {
    id: '{{SUB_ITEM_ID}}',
    deleted: true,
  },
  {
    price: '{{NEW_PRICE_ID}}',
  },
]

to the retrieveUpcoming function of invoices?

Thanks for waiting, discord is busy today
