Hi 2 shoes

I have got subscription and subscription_items in my DB. I have written

    def update_subscription(self):
        try:
            stripe.Subscription.modify(
                self.subscription.stripe_id,
                cancel_at_period_end=False,
                proration_behavior=None,
                items=[
                    dict(id=item.stripe_id, price=item.price.stripe_id, quantity=item.quantity)
                    for item in self.subscription.items.all() if item.quantity > 0
                ]
            )
            return True
        except:
            return False

but there is a proration

hum might be 'none'

I'm not sure I understand. Is there a question in there somewhere?

[wanton ridge]

well yes, how to change subscription items quantity

at period_end

HI 👋

Is there a particular reason you want to update the quantity at the end of the billing period?

[wanton ridge]

Hi

Yes it's an upgrade or downgrade

[ripe breach]

And do you have an example request ID where you made the above request and a proration was generated?
Here's how you can find a request ID: https://support.stripe.com/questions/finding-the-id-for-an-api-request

[wanton ridge]

I was doing this with bare quantity and price

but I've been advise to use subscriptionitem id

OK, find it and come back to you

OK, found the problem, was due to a string missing

[ripe breach]

Ok great. Does it behave as expected now?

[wanton ridge]

Well not really

I'm afraid

here is the req_70vFe1DKBn4V1b

I create a subs for product A quantity 1

I want to modify subs with product B quantity 1

in my DB, no si_xxxx for subscription item since not create with stripe API

how should my items look like ?

[ripe breach]

You are passing in "" as the value for id in the second item

[wanton ridge]

yep since it is added

[ripe breach]

Then don't provide an id parameter

[wanton ridge]

OK ! understood

And for a deletion ?

a an item ?

is it possible with Subscription.modify ?

[ripe breach]

Yup

[wanton ridge]

item.id, quantity: 0

[ripe breach]

Nope

[wanton ridge]

😄

In the items array you can pass a boolean deleted parameter: https://stripe.com/docs/api/subscriptions/update#update_subscription-items-deleted
