The relevant code:

price = create_price(donation[:reference], monetised_amount, interval, interval_count)
customer = create_customer(donation)
subscription = create_subscription(price, customer, "#{donation[:forename]} #{donation[:surname]}", donation[:email])
invoice = ::Stripe::Invoice.retrieve(subscription.latest_invoice.id, { api_key: private_api_key })
{
  payment_intent_client_secret: invoice.confirmation_secret.client_secret,
  subscription_id: subscription.id
}

and:

      def create_price(reference, amount, interval, interval_count)
        ::Stripe::Price.create(
          {
            currency: amount.currency,
            unit_amount: amount.cents,
            recurring: {
              interval: interval,
              interval_count: interval_count
            },
            billing_scheme: 'per_unit',
            product_data: { name: "Recurring Donation - Reference: #{reference}" }
          },
          { api_key: private_api_key }
        )
      end

      def create_customer(donation)
        ::Stripe::Customer.create(
          {
            email: donation[:email],
            name: "#{donation[:forename]} #{donation[:surname]}",
            address: {
              city: donation[:city],
              country: donation[:country],
              line1: donation[:street],
              postal_code: donation[:zip],
              state: donation[:state]
            }
          },
          { api_key: private_api_key }
        )
      end

      def create_subscription(price, customer, full_name, email)
        ::Stripe::Subscription.create(
          {

            expand: ['latest_invoice'],
            metadata: { name: full_name, email: email }
          },
          { api_key: private_api_key }
        )
      end

hello! this change is documented here:
https://docs.stripe.com/changelog/basil/2025-03-31/add-support-for-multiple-partial-payments-on-invoices#use-for-payment-element-integrations

you should be able to get this from the new confirmation_secret property by expanding that and referencing invoice.confirmation_secret.client_secret

[junior breach]

As I said the confirmation_secret returned from the invoice is nil

[tepid epoch]

ahhh sorry i missed that. can you share an example subscription ID? e.g. sub_***

[junior breach]

From the stripe dashboard or just from how I'm creating it in the code I shared above?

[tepid epoch]

from the dashboard works, i'm looking for the actual ID of the subscription object, e.g. sub_1MowQVLkdIwHu7ixeRlqHVzs

[junior breach]

Sure, one second.

And this will be from 'test mode' if thats fine

Here: sub_1Rax8HFpgOJXHv3IoQQ2SunF

[tepid epoch]

yep test mode is perfect! looking now

it looks like you're just expanding on latest_invoice, what happens if you expand on latest_invoice.confirmation_secret?

it's a little confusing but that property only shows if you expand it

[junior breach]

Thanks I'll give that a try

I'm still getting nil returned, the sub ID: sub_1RaxCjFpgOJXHv3IqDAFk0Ty

[vale parrot]

hi! I'm taking over this thread. having a look

[junior breach]

`NoMethodError - undefined method 'client_secret' for nil:

          payment_intent_client_secret: invoice.confirmation_secret.client_secret,`

[vale parrot]

Here's the request you made: https://dashboard.stripe.com/test/logs/req_cK9AHwDKjUkzpv
and in the response from Stripe I do see confirmation_secret.client_secret

I think it's because it's not invoice but latest_invoice you should use.

on the subscription object it:s latest_invoice.confirmation_secret.client_secret

[junior breach]

So I should change from 'retrieving' it to just chaing from the subscription?

currently:

        invoice = ::Stripe::Invoice.retrieve(subscription.latest_invoice.id, { api_key: private_api_key })

[vale parrot]

you don't need to retrive the invoice at all, the subscription directly conntains the information you need since you are using expand.

to learn more about how expand works, I recommend reading this guide: https://docs.stripe.com/expand

[junior breach]

Ah, thanks the docs were showing otherwise in places.

Just put through a test and it went through fine, thanks for your help!
