JS API Requests for Different Site Page Types

In order to use Yespo product recommendation algorithms and customize their display on your side (appearance of blocks, display pages, etc.), follow these steps:

Examples of Requests

On the Home Page and 404 Page

eS('getRecommendations', {
  'variantId': 'r554v778'
  }, function(error, products) {

  if (error) {
            console.error(error);
            return ;
        }

});

On the Product Page

eS('getRecommendations', {
  'variantId': 'r554v778',
  'productId': 'MX-1512\42'
  }, function(error, products) {

  if (error) {
            console.error(error);
            return ;
        }

});

On the Cart Page

eS('getRecommendations', {
  'variantId': 'r554v778',
  'productIds': ['123', '543534']
  }, function(error, products) {

  if (error) {
            console.error(error);
            return ;
        }

});

On the Cart Pop-up

Use the StatusCartPage event to determine the page type and display recommendations on the cart pop-up. Example:

eS('sendEvent', 'StatusCartPage');

On the Categories Page

eS('getRecommendations', {
  'variantId': 'r554v778',
  'categoryKey': 'cK'
  }, function(error, products) {


  if (error) {
            console.error(error);
            return ;
        }
});

The JS API method is asynchronous, which allows not to wait for the execution of other functions on the site.

Filtering Recommendations

Filtering recommendations through the JavaScript API allows you to show products on your site by filtering recommendations based on data from the feed or contact information stored on your side. For example, you can filter recommendations by the city of residence, clothing size, favorite brand, promotional offer, etc.

Filtering recommendations through JS API saves you from changing the filtering rules in the data source in Yespo account every time.

Request format:

eS('getRecommendations', {
    variantId: 'r362v614',
                'filters': {
                       'include': [{'name': 'city', values: ['Kiev','Kharkiv']}]
                }
  },
  function(error, products) {
    if (error) {
      console.error(error);
      return;
    }
  }
);

Request parameters:

Name

Type

Description

filters

Optional Object

A parameter that includes filtering rules.

include

Optional List

Strict filtering: recommend only products according to the given parameters. For example, show only products of a certain brand.

exclude

Optional List

Strict filtering: products with specified parameters are not shown. For example, do not show discount items.

should

Optional List

Non-strict filtering: products with specified parameters shown in priority, others by default (if there should be 20 recommendations in the search results, 5 products with the specified parameters will be shown, the remaining 15 — without applying the filter). For example, include products from a new collection in recommendations.

name

Required String

The name of the product parameter from the product feed.

values

Required List

List of values to filter. The comma in values is the OR operator (values: ['Kiev','Kharkiv']).

You can also define a field (parameter) by which product categories will be filtered in the feed for display in recommendations. To do this, specify the desired categoryField value in the request.

Example request:

eS('getRecommendations', {
    variantId: 'r1673v2111',
		categoryKey: 'BATHROOM',
    categoryField:'tags_all_category_names'
  },
  function(error, products) {
    if (error) {
      console.error(error);
      return;
    }
  }
);

where tags_all_category_names guarantees a search across all values in the category tree.
