Shop Pay Installment Price Update

Topic summary

  • Core issue: A merchant’s product page updates price based on dynamic customizations (not tied to Shopify variants), and they need the Shop Pay installment display to reflect the new price.

  • Context: Customizations are applied via dynamic options and adjust the price that is added to the cart. The request focuses on updating the Shop Pay installment messaging/amount when these on-page price changes occur.

  • Constraints: Options are not variant-based; price changes happen dynamically on the product page (tags: HTML, JavaScript), implying a need to re-render or recalculate the installment snippet.

  • Ask: How to programmatically update or refresh the Shop Pay installment component after the price changes.

  • Status: No solutions or responses yet; unresolved and open.

I have a product page where the price can change depending on which customization is selected. These customizations are not tied to a variant, but are dynamic options we offer that will update the price added to the cart. How can I update the Shop Pay installment when these prices change?
