just clarifying -
which removes all other payment methods, so there can only be one-at-a-time.
don't thinksetupmode Checkout removes any existing PaymentMethods from a Customer. It just sets up and attaches a PaymentMethod to a Customer
reading the rest too
does the stripe checkout window already allow users to select an existing payment method? if so, this may complicate my "one singular linked payment method" model?
yeah so if a Customer already hasnattache PaymentMethods, Checkout surfaces them
I am not a 100% on whether this only works for mode: payment or also mode: subscription
lemme check

my intention is for my backend to enforce the one-payment-method-at-a-time rule in the checkout.session.completed webhook.
tepid zenith
it seems like i might be able to use paymentIntents for the purchases of digital products, since payment intents accept a payment_method. however, paymentIntents do NOT seem to accept a price — only an amount — and so i cannot specify a recurring subscription there.
since you're creating Subscriptions, don't use PaymentIntents for that, those are for one time payments.
river oasis
understood — i can use PaymentIntents for the one-time digital product payments.
okay, so if stripe checkout surfaces all the customer's payment methods, and allows the customer to select an existing payment method or enter a new payment method — i suppose my webhook for checkout.session.completed can find the payment_method on the setup_intent, see if it's a new payment method, and then enforce the one-at-a-time thing by detaching old payment methods and updating existing subscriptions.
➡️ in this case, i suppose all my created checkout sessions will specify payment_intent.setup_future_usage.
tepid zenith
ok checked, yeah subscription mode does work with saved PaymentMethods on a Customer and also surfaces the invoice_settings.default_payment_method on a Customer (if that field is set )
i suppose my webhook for checkout.session.completed can find the payment_method on the setup_intent, see if it's a new payment method, and then enforce the one-at-a-time thing by detaching old payment methods and updating existing subscriptions.
correct yes
river oasis
so whenever the payment method changes, either by a checkout session in "setup" mode or by a checkout session in "subscription" mode, i should set the customer.invoice_settings.default_payment_method to the new payment method, and also enforce my one-at-a-time rule by detaching the obsolete payment methods.
i've also noticed that PaymentIntents do not accept a price id, and so i do not need to model my digital content as stripe products or prices.
does this sound correct?
➡️ so for the purchase of digital products, i only engage a checkout session in "setup" mode when the customer does not already have a default_payment_method — and then, once the customer has a default_payment_method, i can proceed to create a PaymentIntent
➡️ and for subscription purchases, i always create a new checkout session in "subscription" mode with payment_intent.setup_future_usage set to off_session, always saving the resulting setup_intent.payment_method as the default_payment_method

reading now one sec
i've also noticed that PaymentIntents do not accept a price id, and so i do not need to model my digital content as stripe products or prices.
yes you wont use PaymentIntents since you are not creating a one time payment
so for the purchase of digital products
is this a one timepayment? a recurring paymetn?
if so, why are you using Checkout in setup mode then?
and then, once the customer has a default_payment_method, i can proceed to create a PaymentIntent
➡️ and for subscription purchases, i always create a new checkout session in "subscription" mode with payment_intent.setup_future_usage set to off_session, always saving the resulting setup_intent.payment_method as the default_payment_method
wait I'm confused
why not use Checkout directly
for the Subscription and one time payment
and Not do the setup mode CHeckout
river oasis
hello, so on my stripe connect platform, merchants will be selling both subscription memberships and also one-time-payment digital products.
tepid zenith
yeah so why not use Checkout directly in that case
river oasis
the plan is to have a "billing" panel, where users can link their credit card, and update it, and remove it.
after they've linked a card, they can purchase items with one click.
river oasis
if they try to purchase a digital item before they have a linked payment method, they will be prompted with a "setup" checkout.
for subscriptions, checkout in "subscription" mode is the only way, whether they have a payment method already linked or not. after they checkout a subscription, my system will set whichever payment method they use as the "current" payment method, which will be displayed in the billing panel.
tepid zenith
ok hold one
once the card is set up
you will not be creating another CheckoutSession in subscription mode
you already have the card saved
so you just create a Subscription via the API
river oasis
oh okay -- this is new information, i originally thought i had to create a paymentintent to utilize an existing payment method --
but if i can just create a new subscription object, and provide it an existing payment method -- without prompting a checkout -- that would be great
➡️ it looks like i can create a new subscription object, directly, and specify subscription.default_payment_method with the customer.invoice_settings.default_payment_method -- does that sound correct?
tepid zenith
oh okay -- this is new information, i originally thought i had to create a paymentintent to utilize an existing payment method --
you still can do that for a one-time payment
but if i can just create a new subscription object, and provide it an existing payment method -- without prompting a checkout -- that would be great
but yes absolutely, this works and you should do this, no need to create Checkout a second time
➡️ it looks like i can create a new subscription object, directly, and specify subscription.default_payment_method with the customer.invoice_settings.default_payment_method -- does that sound correct?
yes
river oasis
will that action immediately charge the card for the first payment cycle? or is another action required?
tepid zenith
which action
river oasis
creating the subscription object
tepid zenith
well there is a whole guide on that
it could or could not immediately succeed , all depends on whether a bank allows or declines a payment
recommend going through this thoroughly
your case might be a bit simpler cause you do set up cards via Checkout ahead of time
but you still have to handle Subscription payments requiring authentication OR declining (hence adding a new card)
