Hello, can you tell me more about what you have in terms of Stripe objects here? Do you have an existing subscription in the Stripe system that you want to make free?

ya im getting the free sub data like this js const stripeSub = await stripe.subscriptions.list({ limit: 1, customer:newUser.stripeId });

so its a free sub that i created

but i want to change the subscription to the paid version they had on chargebee

Gotcha, we have this doc on upgrading and downgrading subscriptions https://stripe.com/docs/billing/subscriptions/upgrade-downgrade

You will make an update call on the subscription where you give it a new price and tell Stripe whether to or not to create a prorated charge with the change

[fiery spindle]

so like this ```js
stripe.subscriptions.update(subscription.id, {
cancel_at_period_end: false,
proration_behavior: "i dont know what to put here for false",
items: [{
id: oldSubItem,
price: newPriceVariable,
}]
});

i want it not to charge til end of billing cycle

You have two options here. You can set proration_behavior: "none" if you don't want the user to be charged at all for this change or you can set proration_behavior: "create_prorations" if you want to charge/credit the user at the begginning of the next month

Sorry, forgot the context for a second. This is a free trial/subscription so you will want to set none that way the user won't get charged at all until the next month
