https://docs.stripe.com/api/invoices/create_preview
This is the documentation I've used so far.

Hmm I don't think you can use both parameters at the same time

#

Have you tried using upcoming invoice API instead to see if that works?
https://docs.stripe.com/api/invoices/upcoming

#

did that work?

scenic tinsel Oct 23, 2024, 8:45 PM

#

Nope

#

same issue

#

I think my only choice is to preview the invoices with the customer details without providing a customer_id

honest carbon Oct 23, 2024, 8:45 PM

#

mm I see.
taking a step back, what are you trying to do with preview?

Are you trying to show what the proration would look like?

scenic tinsel Oct 23, 2024, 8:46 PM

#

if they use a promotion code later on

#

I know proration wouldn't work because the recurring vs single charge logic doesn't work like that.
But I also rely on the preview endpoint to check how taxes apply for a customer

Would you switch them immediately to lifetime? If so you could switch to a "free Price" like a monthly Price first with an extra InvoiceItem for the one-time lifetime fee

scenic tinsel Oct 23, 2024, 8:54 PM

#

So you mean in the preview request, preview them going to a free price id, with the added one time fee?
Wouldn't that throw the same error that an invoice_item cannot be used at the same time as the subscription_details?

#

You wouldn't cancel for real since you're switching them to a say $0/month Price. That would immediately prorate + charge the extra fee. And you can cancel after that.
A bit of a hack but I think it could work

scenic tinsel Oct 23, 2024, 8:58 PM

#

But that would mean I have to create 2 different invoices right?

formal gazelle Oct 23, 2024, 9:06 PM

#

You would have a first Invoice switching them to the lifetime Price (one-off InvoiceItem) + a fake $0/month fee + proration for the current Price.
And then you cancel which doesn't need an Invoice since there's nothing to pay at that point

scenic tinsel Oct 23, 2024, 9:14 PM

Right, I was able to get what I wanted just using the customer_details instead of the customer_id.
I'll try this approach If I get more time at work!

Thanks for the help and sorry for the trouble!
