Submit new product price when add to cart

Shopify Discussion
1

Hi, I’m creating a new Shopify App for product option with an additional price. For example, on the product page, the product’s price is 10$, when selecting an option, the additional price is 5$. If I add that product with an option to cart, how can I submit the total price (15$) instead of product’s price (10$)?

Thank you.

Hello @tnet1399 ,

You can follow these steps:

  • Create a new cart in your Shopify app, or retrieve the existing cart if one already exists.
  • When adding the product with an option to the cart, use the variant ID that corresponds to the selected option with the additional price.
  • Calculate the total price for the product and the selected option by adding the base price of the product to the additional price of the selected option.
  • Update the line item in the cart to reflect the new total price by setting the price attribute of the line item to the calculated total price, like this:
cart = ShopifyAPI::Cart.find(cart_id)

line_item = cart.line_items.find(line_item_id)

total_price = line_item.variant.price + selected_option_additional_price

line_item.price = total_price
line_item.save
  • Save and preview.

Hope this will help.

@OneCommerce Can you please share me the API reference and can you tell me that could we update the cart price by adding the additional prices using RestFull API or GraphQL.
