In this article, you will learn how to implement multi-currency in Nosto. When the implementation is complete, you will be able to display product prices (in any feature) in different currencies.
Prior to the multi-currency implementation, ensure that the Nosto tagging is correctly in place. Some of the tagging must be slightly amended to support multi-currency.
For instructions on integrating with Shopify's multi-currency, please go here.
The product page tagging must be amended to denote the primary currency code of the product. Typically, most retailers have a primary currency which is the default currency of the inventory.
For example, a US-based retailer who sells in Euros (EUR) and Sterling Pounds (GBP) would have US Dollar (USD) as the primary currency while Euro (EUR) and Sterling Pounds (GBP) would be secondary currencies whose exchange rates would need to be sent via an API.
An additional span tag must be placed within the product page tagging with a class name
variation_id. The tag is a child element of the
<div class="nosto_product" style="display: none;">.........<!-- Variation ID for the primary currency --><span class="variation_id">USD</span></div>
Note: The code in the
variation_idelement must remain static, regardless of the currency active on-site. This is the primary currency of your catalog. Although
variation_idelement often has the same currency code as in the
price_currency_codeelement and may seem redundant, they support different use cases and both need to be tagged.
Yes. Prices for all SKUs will automatically be converted using the same logic. As long as your SKUs are tagged, no additional changes are needed.
The cart and order tagging can be left as-is but the prices must be in the customer's currently active currency. For example, a customer shopping in Swiss Francs (CHF) should have all the cart items tagged in Swiss Francs (CHF). Failure to do so will result in incorrect prices in any triggered mails such as abandoned cart or order followup.
Once you have amended the product tagging, an additional DIV element must be added to all the other pages (including the product page itself). The tag should not be encapsulated in the
nosto_product DIV tag. The information sent in the tag refers to the currency active of the customer.
<div class="nosto_variation" style="display: none;">USD</div>
For example, on the site of a US-based retailer who sells in Euros (EUR) and Sterling Pounds (GBP), if the customer changes the currency to Sterling Pounds (GBP), the
nosto_variation element should show
GBP. If the customer changes the currency to Euros (EUR), the
nosto_variation element should show
In order to send the exchange rate multipliers to Nosto, you will need to use our exchange-rates API. Below is a small snippet of what the payload looks like.
In the example above,
0.77 is the exchange rate from US Dollars (USD) to British Pounds (GBP) and
0.91 is the exchange rate from US Dollars (USD) to Euros (EUR).
valid_until entry defines the expiration date. When the expiration date is reached, the exchange rates won't be applied anymore and prices will be hidden for all the secondary currencies to prevent displaying outdated prices.
When recommendations are served, then exchange rates are dynamically applied to the product prices to reflect the active currency.
Once the tagging changed have been done and the API implemented, you need to configure and enable it from your admin panel under Settings > Other > Multi-Currency. Toggle the Use Multiple Currencies and Use Exchange Rates switches on and set the variation ID of the primary currency via the input field and toggle on the exchange rates switch.
Note: Ensure that the Variation ID of the primary currency matches the value sent via the
variation_idelement in the product tagging.
You will also need to configure the price formatting for your primary and secondary currencies.
Once you enabled multi-currency and made an API call, you can review the exchange rates received by Nosto by navigating to Settings > Other > Multi-currency.
You can also preview the product prices for different currencies by navigating to Tools > Products and choosing a product.
You will see one or more dropdowns that contain the prices and price calculation for the currency.
When you have reviewed your set-up, Nosto updates in real-time product prices for all the currencies and display the appropriate currency to the right target groups of users. You’re all set and ready to go live with our features.
