Subscription app should let customers to change payment methods

[Webdibs]

I've sent the app to shopify and got rejected, I needed to let customers to change payment method for his subcriptions. But they don't give any more information, just this link:

https://shopify.dev/apps/store/requirements#a-storefront-requirements

According to the link, we need to use:

https://shopify.dev/api/admin-graphql/2021-10/objects/customerpaymentmethod#fields-CustomerPaymentMe...

So do we need to request for customer credit card? Isn't that dangerous? Also, do we need to show current payment method?

Hello Webdibs, Did you solve the problem ?

[Webdibs]

Yes, I needed to create a button to generate the email that is sent to the customer to change their payment info

[masumluf]

could you tell me how to generate the email ? which api or gql should I trigger ?

[Webdibs · Accepted solution]

I used GQL's customerPaymentMethodSendUpdateEmail call

More info at:

https://shopify.dev/api/admin-graphql/2022-01/mutations/customerPaymentMethodSendUpdateEmail

where i will get paymentId ? could you provide a sample paymentId ?

[Webdibs]

You can get it from contract's information. There's a customerPaymentMethod with that info.
