Support multiple currencies on storefronts

• You've reviewed and met the requirements on the Querying data with the Storefront API page.
• You've created products and product variants in your store.
• You've queried the Shopify card vault to obtain the session ID, which allows you to complete the checkout in this tutorial. For a detailed tutorial on how to create and complete checkouts, refer to Create a checkout with the Storefront API.

Shopify stores have a store currency, which is the default currency that's used to display prices on a storefront.

Merchants can enable multiple presentment currencies from their Shopify Payments settings. Presentment currencies are the currencies that can be used to display prices to customers on a storefront and checkout.

The following example shows how to query a shop's paymentSettings object to return a list of enabled presentment currencies:

POST /api/2022-04/graphql.json

You can query specific product variants to return pricing information in different presentment currencies. By default, all currencies are returned, or you can use the presentmentCurrencies argument as part of the presentmentPrices object to return a specific currency.

When merchants set sale prices for products, the price is the sales price and original price is the compare at price.

The following query returns the compareAtPrice and price for the product variant's Australian (AUD) presentment currency:

POST /api/2022-04/graphql.json

You can query products to return the range of variant prices for presentment currencies. To get a price in a specific presentment currency you can query node for a given product variant.

You can return the presentmentPriceRanges by querying products. By default, all currencies are returned, or you can use the presentmentCurrencies argument on presentmentPriceRanges to return a specific currency.

The following query returns the presentmentPriceRanges for all of the store's supported currencies:

POST /api/2022-04/graphql.json

The following query only returns the presentmentPriceRanges for the AUD currency code:

POST /api/2022-04/graphql.json

Apps can create checkouts using any of the enabled presentment currencies on a merchant's store.

To create a checkout using a specific currency, include the currency code as an input argument in the checkoutCreate mutation:

POST /api/2022-04/graphql.json

When you complete a checkout, you can provide the currency code of the created checkout as an input argument on the checkoutCompleteWithCreditCardV2 mutation.

To complete the payment, send the payment information, including the amount, currencyCode and billingAddress fields. Send the payment session ID as the vaultID.

The following mutation completes the checkout using Australian currency by sending the AUD currency code as part of the payment object. The example uses the session ID from the Shopify card vault to complete the mutation.

POST /api/2022-04/graphql.json
