Help Needed: Workarounds for Updating Customer Payment Methods with Third-Party Providers

Shopify Functions
1

Hello Shopify Community,

I’m currently working on integrating a feature within our subscription app to allow customers to update their payment methods, specifically for third-party providers like Stripe and PayPal. The documentation outlines that we can send a customer payment update email using the customerPaymentMethodSendUpdateEmail mutation, but this only supports ShopPay, and for other gateways, it returns an error: “No supported payment gateway found.”

In addition, I need to pass details such as customer_id and payment_method_id from Stripe, but it’s unclear how to retrieve this information directly through Shopify’s API.

Here’s what I’ve tried so far:

Reviewing Shopify Documentation: I’ve reviewed the provided mutation options, but none seem to support updating payment methods for third-party gateways.
Direct PayPal Integration: For PayPal, it appears the only option is to redirect customers to manage their billing agreements on PayPal directly.

Is there anyone who has successfully implemented a workaround for this scenario or has suggestions on managing customer payment methods when using third-party payment gateways in a Shopify app?

I would greatly appreciate any insights or guidance on this issue!

Thank you,

Hi!

I had a chat with a support agent just now and got this conclusion.

  1. Custom offsite payment extension development needs approved accounts and upgraded plans.
  2. Shopify is not accepting approving applications right now.
  3. This means custom offsite payment extension development is impossible.
  4. Another option is to develop a checkout UI extension, but it cannot grab the order information.

If you have any other surprising news, please let me know soon.
Thanks
