[Checkout] Store credit doesn’t update credit-card installments UI (UI shows subtotal; final charge is correct)

Extensions
1

When “Use store credit” is enabled and the buyer selects Credit card, the installments widget still shows the full subtotal instead of the net total after store credit. The final charge is correct, but the UI misleads the buyer during payment selection.
Steps to reproduce

  1. Add items → 2) Enable Use store credit → 3) Choose Credit card → 4) Open installments selector.
    Observed: installments total = subtotal.
    Expected: installments total = net total (after store credit).
    Support note: Shopify Support said this is due to a missing webhook/event to refresh totals; it’s in the backlog.
    Impact: customer confusion, checkout friction, potential drop-offs.
    Ask: please provide (a) an event/callback in Checkout to refresh payment totals when store credit changes, and/or (b) a native fix so the installments component always uses the net total. A temporary workaround would also help.

Hey @Lucas_de_Oliveira_Ri :waving_hand: - I can’t guarantee anything in terms of when/if we’d implement this feature, but I can take a look to confirm if it’s in our backlog/set up a feature request for you at the very least. Do you happen to have a Support ticket ID by any chance? I noticed you mentioned you reached out to support, so I can take a look at that ticket for you and trace things back.

Hope to hear from you soon!

Hey @Alan_G - I’m Lucas’ work colleague and I’m also looking forward to a solution for this issue since I’m a seller and this impacts directly my converstion rate and customer satisfaction. I’m pretty sure it’s affecting all Brazilian sellers. I’m in touch with Shopify Support through ticket 61372614, feel free to take a look. I appreciate if you can give us an idea of when you expect this issue to be fixed, it would be a great improvement!

Thanks so far :waving_hand:

Hey @Consolatio_Store - thanks for following up and for sharing the ticket ID. Wanted to follow up to confirm that this is something we have logged as a feature request. Right now, the behaviour does look to be expected (although it’s not ideal), but I’ll share our thread here internally so that we have your and @Lucas_de_Oliveira_Ri ‘s feedback logged as well, since I do agree that using the net total would make sense after including the amount paid via store credit in the checkout “final” total.

We do mention this behaviour in the docs for Checkout UI Extensions, but it is a little hidden for sure:

Specifically this part:

    {
      title: 'useTotalAmount',
      description:
        'Returns a `Money` value representing the minimum a buyer can expect to pay at the current step of checkout. This value excludes amounts yet to be negotiated. For example, the information step might not have delivery costs calculated. Applied gift cards and store credit are excluded.',
      type: 'UseTotalAmountGeneratedType',
    },
  ],
  related: getLinksByTag('apis'),
};

export default data;

Definitely agree that this could be changed to reflect applied gift cards and store credit though (or maybe offering a different target that includes applied credits). I can’t guarantee anything in terms of a roadmap, but I hope this helps clarify things, let me know if I can help out further!
