Hello and thx for the rapid answer

#

i've already read that , but if i understand correctly , this only works for updating an existing subscription right ?

#

Does this mean that i have to change the way i create subscriptions ?

#

You'd need to pass either the customer or subscription parameter: https://stripe.com/docs/api/invoices/upcoming

Stripe API reference – Retrieve an upcoming invoice

Complete reference documentation for the Stripe API. Includes code snippets and examples for our Python, Java, PHP, Node.js, Go, Ruby, and .NET libraries.

#

But how are we expected to calculate prorations if there's no pre-existing subscription?

#

like with subscription_items ?

#

thx i think i got my answer in the API docs

#

The identifier of the subscription for which you’d like to retrieve the upcoming invoice. If not provided, but a subscription_items is provided, you will preview creating a subscription with those items

#

i think that's it

#

lemme try this out in Postman

#

Sure!

#

ok this works

#

So that's what i'm expecting,
I give you a customer and a price in the items, a billing_anchor_cycle, and start_date, and you give me the right amount. Thx
