hi there!
what are you trying to do? you want to reuse the existing payment method saved on the customer?
fathom galleon
Hi, yes I want to reuse existing payment method and avoid adding same PM to a customer on subsequent payments
quick mantle
can you share the request ID (req_xxx) where you created a new subscription? or the subscription ID (sub_xxx) itself?
fathom galleon
Let me find it
Customer: cus_SGECjd6Dy1a5Q5
1st Sub Id: sub_1RLhkWCMkkLn6luHGaTIdzop
2nd Sub Id: sub_1RLiecCMkkLn6luHUlFNWNbr
quick mantle
got it. you could set this parameter when creating the second subscription: https://docs.stripe.com/api/subscriptions/create#create_subscription-default_payment_method
fathom galleon
You mean "default_payment_method", right?
quick mantle
yes, that's exactly what I linked
fathom galleon
Just double-checking 🙂
Okay, will try to do that
Also, what are the base practice to reuse payment method from Appl/Google Pay? Is this flow correct:
- Check if customer payment method is equal to current PM
1.1 If yes --> create subscription with default_payment_method
1.2 If no --> create subscription with payment_settings.save_default_payment_method = 'on_subscription' and save this PM as a default one
quick mantle
I don't understand step 1. can you clarify what you mean by this?
fathom galleon
There will be many subscription payments and as I understood every payment has new payment method id so in this situation I will need to reuse the first PM id for subsequent payments. In order to check is it first payment I am using default PM from customer object. If it is null then I will need to create new subscription with saving PM, if not then I must reuse it.
- By "customer payment method" I meant default PM that is attached to a customer object;
- By "current PM" I meant the payment method with comes on a current payment
There might be the case where users lost their card or whatever and try to pay with a new card from Apple Wallet. Should I then change default PM on every payment so that user will always have possibility to pay? In another words, in PM associated to Apple Wallet where doesn't matter what card user will use, Stripe will always define it automatically or PM is associated with a card from Apple Wallet?
Does this clarify something?
quick mantle
sure. but what did you meant earlier by "Check if customer payment method is equal to current PM"?
in general, if the customer already has a saved payment method, then you can directly create the subscription with default_payment_method, there's nothing to "check".
fathom galleon
I meant that there will be many subscriptions payments. One of them will be at first time and one will be at second time. I will need to create subscription with argument default_payment_method only on the second purchases, right? Because at first time user does not have default payment method so I won't know which payment method I shoud put in a default_payment_method to reuse it so will need to check before creating every subscription does user has PM and maybe is it equal to the incoming payment, right or I am mistaking?
quick mantle
I'm sorry I'm confused.
when you want to create a subscription, check if the customer has a payment method saved:
- if not, then create the subscription, collect the payment method detail, and the subscription will be active. and every month the customer will be automatically charged.
- if yes, create the subscription with
default_payment_method. and every month the customer will be automatically charged.
