In this article, you will learn how to implement Nosto accordingly, if you have applied a multicurrency policy to your online store. When the implementation is completed, you will be able to display product prices in different currencies to relevant target groups.

Note: if you use a 3rd party exchange rate service to update frequently product price information, you need to follow the advanced multi-currency implementation guide that can be found here.

Prior to the multicurrency specific implementation, make sure that the Nosto tagging is correctly in place. The Nosto Tagging Guide can be found here. Once the tagging is correctly applied, data exchange occurs and Nosto tracks behavioral events and updates product catalogue information in real-time.

However, tagging must be slightly extended to achieve a generic multicurrency implementation. Only front-end resources are required and this can be done within just a few HTML tags.

The Nosto product page tagging must be extended to include information related to the different currencies offered by the online store.

Typically, a primary currency has been set for the online store. For example, a US based retailer could offer Euro and British pound to European customers. US Dollar is the primary currency while Euro and British pound are in this example secondary currencies.

The 1st step is to inform Nosto about the primary currency. An additional span tag must be placed within the product page tagging with a classname variation_id. The tag is a child element of the nosto_product div tag.

The 2nd step refers to the information related to the secondary currency(ies). A child div tag with a classname variation_id must be placed within the Nosto product page tagging. The div tag must encapsulate several child span tags sending information about the identifier of the currency, the price currency code, the price and the list price. There can be multiple secondary currencies. For each secondary currency, you must add a unique variation_id div element encapsulating the relevant information.

Following the example above, the extended version of the product page tagging would have the following structure:

Note: The tagging above needs to remain static, regardless of the currency active on-site.

Once you have extended the product page tagging, a separate and additional nosto_variation div tag must be added to all the pages (including the product page itself). The tag shouldn’t be encapsulated in the nosto_product div tag. The information sent in the tag refers dynamically to the currency active on the user’s browser.

When the tagging has been extended, you need to adjust the settings in your admin panel under Settings >> Currency Settings. Toggle the switch on and set the variation ID of the primary currency via the input field:
​

Note: Make sure the variation ID of the primary currency matches the values sent via the Nosto product page tagging through the variation_id tag and sent via all pages through the nosto_variation tag.

Set up the Price formats according to your primary currency and secondary currencies:

Once you are done with adjusting the settings in your Nosto admin panel, you can review, if product information is correctly updated. You can also review if product information are correctly updated. This can be reviewed under Catalog Explorer >> Products >> select a Product >> in tab "Attributes" check the field "Pricing" .

When you have reviewed your setup, Nosto updates product prices for all the currencies in real-time and displays the appropriate currency to the right group of users.
