Tracking Events

Upon viewing the homepage

When viewing a homepage, there's no context to be provided, so invoking the viewFrontPage will suffice.

nostojs(api => {
  api.defaultSession()
    .viewFrontPage()
    .setPlacements(['homepage-nosto-1', 'bestseller-recs'])
    .load()
    .then(data => {
      console.log(data.recommendations);
    })
});

Upon viewing a product

When viewing a product, you should send the product-id of the current product being viewed. Unlike the regular implementation, you do not need to pass the entirety of the product metadata.

nostojs(api => {
  api.defaultSession()
    .viewProduct('product-id')
    .setPlacements(['product-crosssells'])
    .load()
    .then(data => {
      console.log(data.recommendations);
    })
});

Upon viewing a product variant

Optional event that can be sent to signal that a specific product variant (SKU in Nosto terms) is being viewed. Typical use case for sending this event would be from product detail page when the user selects a product variant, such as some specific color and/or size. The recommendations can then be configured to update and give preference for products that have similar variants available. For example "Other products also available in the same size". Product variant views are added with the function viewProductSku:

nostojs(api => {
  api.defaultSession()
    .setResponseMode('HTML')
    .enableCampaignInjection()
    .viewProductSku('product-id-x', 'sku-id-y')
    .setPlacements( api.placements.getPlacements() )
    .load()
});

This example leverages dynamic placements and html rendering

Upon viewing a category

When viewing a category, you should send the fully qualified name of the current category. This is not necessarily the same as the handle of the category used in the address of the category page.

nostojs(api => {
  api.defaultSession()
    .viewCategory('/Womens/Dresses')
    .setPlacements(['category-related'])
    .load()
    .then(data => {
      console.log(data.recommendations);
    })
});

When the category or collection id is available it can be provided via

nostojs(api => {
  api.defaultSession()
    .viewCategory('/Womens/Dresses')
    .setCategoryIds(['431783631'])
    ...
});

It is needed for accurate attribution in certain Nosto products such as Category Merchandising.

You don’t need to ensure the case-sensitivity of the category being passed so long as the path is tagged in the same way as your products’ categories are.

On Shopify, the collection title should be used, so in the snippet above, use simply "Dresses" instead of the collection handle.

Tagging the categories

Nested categories must always be delimited by a slash. For example, /Home/Accessories is a valid category while Home > Accessories is not.

Upon doing a search

When viewing the results of a search, you must send the exact search-term as queried for.

nostojs(api => {
  api.defaultSession()
    .viewSearch('womens dresses')
    .setPlacements(['search-related'])
    .load()
    .then(data => {
      console.log(data.recommendations);
    })
});

Note: You don’t need to normalize or encode the search query in any way.

Upon starting a checkout

When viewing a checkout page, there's no context to be provided, so invoking the viewCart will suffice.

nostojs(api => {
  api.defaultSession()
    .viewCart()
    .setPlacements(['cart-related'])
    .load()
    .then(data => {
      console.log(data.recommendations);
    })
});

Upon placing an order

On all thank-you and order-confirmation views, the order confirmation metadata must be passed.

The order confirmation metadata is used for sending personalised order-followup emails, personalise the recommendations e.g. order-related, for segmentation insights and conversion statistics.

Important Even if you would not display any recommendations in your order-confirmation view you must still set placements (.setPlacements(...)) and load (.load()) the results. Setting the order works in a similar manner than cart and customer and an action must be performed for the data to be sent to Nosto.

nostojs(api => {
  api.defaultSession()
    .addOrder(
      {
        "external_order_ref": "145000006",
        "info": {
          "order_number": "195",
          "email": "[e-mail]",
          "first_name": "Mridang",
          "last_name": "Agarwalla",
          "type": "order",
          "newsletter": true
      },
      "items": [
        {
          "product_id": "406",
          "sku_id": "243",
          "name": "Linen Blazer (White, S)",
          "quantity": 1,
          "unit_price": 455,
          "price_currency_code": "EUR"
        }
      ]
    })
    .setPlacements(['order-related'])
    .load()
    .then(data => {
      console.log(data.recommendations);
    })
});

Upon viewing a page that was not found (404)

When viewing a page / view that was not found, there's no context to be provided, so invoking the viewNotFound will suffice.

nostojs(api => {
  api.defaultSession()
    .viewNotFound()
    .setPlacements(['notfound-nosto-1', 'bestseller-recs'])
    .load()
    .then(data => {
      console.log(data.recommendations);
    })
});

Upon viewing a general page

When a page with a type - other than the ones listed here - is viewed, there's no context to be provided, so invoking the viewOther will suffice.

nostojs(api => {
  api.defaultSession()
    .viewOther()
    .setPlacements(['general-recommendations'])
    .load()
    .then(data => {
      console.log(data.recommendations);
    })
});
