tacit dew Mar 25, 2022, 2:27 PM

#

Can you explain more what you are trying to do? With as many details as possible

plush valve Mar 25, 2022, 2:28 PM

#

So right now we wanna update default payment method from mobile app

#

We will call API to set it as default payment for subscription

#

But in sdk I can’t get payment method id

#

What I can get only last 4 Digits and image

#

https://stripe.com/docs/billing/subscriptions/build-subscriptions?ui=elements#default-payment-method

Build a subscriptions integration

Create and manage subscriptions to accept recurring payments.

#

Our backend guy already created an API to set default payment method b

#

But he need payment method id

#

Right now I am unable to get it

tacit dew Mar 25, 2022, 2:34 PM

#

Are you using the card element or mobile payment element?

plush valve Mar 25, 2022, 2:35 PM

#

I am on mobile side

#

How can I know which one I am using

tacit dew Mar 25, 2022, 2:36 PM

#

yeah I understand

#

Are you using this guide? https://stripe.com/docs/payments/accept-a-payment?platform=ios&ui=payment-sheet

#

What guide are you following?

plush valve Mar 25, 2022, 2:39 PM

#

#

So I wanna have payment method id to call api update default payment method on platform

tacit dew Mar 25, 2022, 2:46 PM

#

Ok checking with a colleague

plush valve Mar 25, 2022, 2:47 PM

#

Thanks

#

what component are you actually using?The screenshot is the STPPaymentOptionsViewController but are you using it directly or with the STPPaymentContext?

plush valve Mar 25, 2022, 2:52 PM

#

Yes

hollow plinth Mar 25, 2022, 2:53 PM

#

yes you're using it in the STPPaymentContext?

plush valve Mar 25, 2022, 2:53 PM

#

Yes

#

I use it to get the callback

hollow plinth Mar 25, 2022, 2:54 PM

#

makes sense

#

but yeah, the component won't work here, since it's optimised for taking payments, it doesn't just give you a PaymentMethod ID that you can send to your backend.

plush valve Mar 25, 2022, 2:55 PM

#

What is your suggestion?

#

We wanna have that feature from mobile app

hollow plinth Mar 25, 2022, 2:55 PM

#

you should use the STPPaymentOptionsViewController directly instead (https://stripe.dev/stripe-ios/docs/Classes/STPPaymentOptionsViewController.html)

#

that component is just for adding/selecting cards and you get the selected payment method in the didSelect delegate function

plush valve Mar 25, 2022, 2:57 PM

#

And I will present it manually right?

#

Don’t open it from the context

hollow plinth Mar 25, 2022, 3:00 PM

#

yes, you would present it directly

#

// Setup payment Options view controller
        let paymentOptionsViewController = STPPaymentOptionsViewController(configuration: STPPaymentConfiguration.shared, theme: STPTheme.defaultTheme, customerContext: self.customerContext!, delegate: self)
        
        // Present payment Options view controller
        let navigationController = UINavigationController(rootViewController: paymentOptionsViewController)
        present(navigationController, animated: true)

e.g.

plush valve Mar 25, 2022, 3:00 PM

#

How about the callback? Still using old function right?

hollow plinth Mar 25, 2022, 3:00 PM

#

what do you mean by 'callback'?

plush valve Mar 25, 2022, 3:01 PM

#

I mean get selected payment method

hollow plinth Mar 25, 2022, 3:01 PM

#

you get the selected payment method in the didSelect delegate function

#

https://stripe.dev/stripe-ios/docs/Protocols/STPPaymentOptionsViewControllerDelegate.html#/c:@M@Stripe@objc(pl)STPPaymentOptionsViewControllerDelegate(im)paymentOptionsViewController:didSelectPaymentOption:

plush valve Mar 25, 2022, 3:03 PM

#

Oh cool

#

I got it

#

Let me try

#

I can see did select

hollow plinth Mar 25, 2022, 3:10 PM

#

for what it's worth though I wouldn't build it this way, these components are older. You should be using the PaymentSheet mentioned above, with a SetupIntent. (https://stripe.com/docs/payments/save-and-reuse?platform=ios&ui=payment-sheet)

plush valve Mar 25, 2022, 3:12 PM

#

I still can get payment method id in did select function

#

It returned SPTPaymentOption

hollow plinth Mar 25, 2022, 3:13 PM

#

yep it does return that

#

you can cast it to an STPPaymentMethod but you need to check the type

#

for example

selectedPaymentOption = paymentOption
print(paymentOption)
if let card = paymentOption as? STPPaymentMethod {
   let cardId = card.stripeId // "pm_xxx"
   print(cardId)
 }

(using as? in Swift to try to cast if possible).

plush valve Mar 25, 2022, 3:15 PM

#

Oh I can get it

#

It’s seem a solution right?

hollow plinth Mar 25, 2022, 3:18 PM

#

can you expand on the question?

plush valve Mar 25, 2022, 3:21 PM

#

I mean that is a solution

#

Because you suggested using paymentsheet

hollow plinth Mar 25, 2022, 3:26 PM

#

not sure what "that" is, but yes, there are multiple ways to approach this.

The recommended one would be the PaymentSheet integration with SetupIntents since it handles 3D Secure to authenticate the card when it saved, and also lets you use a few different payment methods, but the STPPaymentOptionsViewController can be a simpler option.

plush valve Mar 25, 2022, 4:05 PM

#

Hi, the didselect function return immediately

#

But I wanna get payment method after user select only

hollow plinth Mar 25, 2022, 4:19 PM

#

did you read the documentation for the function, which I linked above?

#

This will be triggered after the view controller loads with the user’s current selection (if they have one) and then subsequently when they change their choice.
