👋 How can I help?

[wind willow]

Hey 🙂 thanks for reaching out. I have a subscription model where each customer could have a custom pricing based on their personal discount.

For example:

• A user has a discount of 10%
• Creates a new subscription
• Gets a discounted price for the first invoice and each month after that too

Now I want to be able to change the personal discount of a user while they are in an active subscription. The way I want it to work is that just the next and future invoices are affected. For example if a user has a current discount of 50% and is in the middle of the period and I change it to 10%, stripe should not charge the customer some calculated amount to make up that other half of the month.

In code I use something like this:

item = SubscriptionCreateParams
    .Item.builder()
    .setTaxRates(List.of(stripeTaxRateKey))
    .setPriceData(SubscriptionCreateParams.Item.PriceData.builder()
        .setCurrency("eur")
        .setProduct(stripePrice.getProduct())
        .setRecurring(SubscriptionCreateParams.Item.PriceData.Recurring.builder()
            .setInterval(SubscriptionCreateParams.Item.PriceData.Recurring.Interval.MONTH)
            .setIntervalCount(1L)
            .build())
        .setUnitAmount(price)
        .build())
    .putMetadata("discount", String.valueOf(discount))
    .build();

and attach it to this subscriptionCreateBuilder:

SubscriptionCreateParams.Builder subCreateParamsBuilder = SubscriptionCreateParams
    .builder()
    .setCustomer(user.getStripeCustomerId().getValue())
    .setMetadata(meta).setBackdateStartDate(firstDay.atStartOfDay(ZoneOffset.UTC).toEpochSecond())
    .setBillingCycleAnchor(billingCycleAnchor)
    .setPaymentBehavior(SubscriptionCreateParams.PaymentBehavior.DEFAULT_INCOMPLETE)
    .addAllExpand(List.of("latest_invoice.payment_intent"))
    .setTransferData(SubscriptionCreateParams.TransferData.builder()
        .setDestination(stripeConnectedAccount)
        .build());

What's the problem you're facing?

[wind willow]

On how to update the actual pricing because I've tried that some time earlier and it says that those prices are archived and cannot be changed.

[tawdry arrow]

Are you going to change to a new price or the discount amount?

[wind willow]

Basically I want to change it to a "backend" sided custom price, no discounts/coupons used by stripe here. More or less the "unit_amount" I guess.

But I think I'll have to create a new price for that and delete the old one?

[tawdry arrow]

After a price is created, the amount can't be updated regardless whether it's been archived. Updating the amount of a price is not supported.

To update the subscription with new price, you may follow this guide: https://stripe.com/docs/billing/subscriptions/upgrade-downgrade

Instead of using price of new price, price_data can be used for new price

Okay so I was thinking about creating a Price with the updated "discounted" price and set the id on the price_data field on the subscription's item?

[tawdry arrow]

The original ask was about using price_data. price_data is an ad-hoc price that doesn't have a price created in advance (no price ID).

If the price has been created and new price ID is available, the ID should be set in price parameter.

[wind willow]

Oh now I get it I think. So stripe uses the data from price_data on subscription creation to create the price object itself and stores it in the "price" field so when I want to update it later on I should put the id of the price I created in the "price" field?

Sorry, I may overcomplicate it haha

Yes, price_data will create an one-time price ID and return in the response under price field

so when I want to update it later on I should put the id of the price I created in the "price" field?
Yes, if you use Price API to create a new price, its ID should be set under price parameter
