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 your implementation is correct. Some of the API calls must be slightly amended to support multi-currency.
The calls 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 property named variation_id must be placed within the product object.
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 emails such as abandoned cart or order followup.
Once you have amended the product metadata, you must change the session usage to also pass the active currency of the customer.
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 setVariation method must be passed GBP. If the customer changes the currency to Euros (EUR), the setVariation method must be passed EUR.
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).
The 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rates won't be applied anymore and prices will be hidden for all the secondary currencies to prevent displaying outdated prices.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 drop-downs that contain the prices and price calculation for the currency.
When you have reviewed your set-up, Nosto updates product prices in real-time for all the currencies and displays the appropriate currency to the right target groups of users. You’re all set and ready to go live with our features.
In order to send the exchange rate multipliers to Nosto, you will need to use our . Below is a small snippet of what the payload looks like.
