Methods

The Smart Discovery API supports the GET HTTP method for retrieving Smart Discovery data.

Syntax

To retrieve Smart Discovery data, make the following GET request:

GET https://<platform_instance>/smartDiscoveryApi?method=strategy&
    origin=<site_origin>&
    strategy=<strategy_id>&
    context=<page_context>&
    cookieId=<local_frosmo_id>

Parameters

Query parameters for Smart Discovery API requests

Parameter	Description	Type	Role	Example
method	Request type. Use the value strategy.	String	Required	method=strategy
origin	Site origin. To find out your site's origin, see Getting your site origin.	String	Required	origin=shop_company_com
strategy	ID of the Smart Discovery strategy whose generated data to retrieve.	String	Required	strategy=home
context	Contextual information about the page where the API request is made. The information allows the API to return the correct Smart Discovery data for the page. The exact information required depends on the page type of the Smart Discovery strategy. The value is a JSON object containing a single page property: the page context object.	Object See Page context object.	Required	# Home page context context={ "page": { "type": "home" } } # Category page context context={ "page": { "type": "category", "category": { "categories": [ "Fashion/Shoes" ] } } }
cookieId	Frosmo ID of the visitor who sees the Smart Discovery. The platform uses the ID to sort the collections in the Smart Discovery based on the visitor's affinities. To get the ID, see Getting a visitor's Frosmo ID. This parameter is required if you want to personalize the Smart Discovery for individual visitors. note Do not set this parameter if the site uses selective profiling and the visitor has opted out.	String	Optional	cookieId=dsr77t.kstzihlx
loginId	Login ID of the visitor who sees the Smart Discovery. The ID allows the platform to get the visitor's affinity profile across multiple browsers. note For the login ID to work on a site, login support must be enabled for the site. To enable the feature, if it's not already enabled, contact Frosmo support.	String	Optional	loginId=3364259119087832
limit	Maximum number of collections to return in the Smart Discovery data. The API returns the top collections by relevance (as determined by item popularity and the visitor's affinities). The minimum value is 1. There is no maximum value. The default value is 20.	Number	Optional	limit=10
profile	Define the visitor's profiling choice if the site uses selective profiling. The choice determines whether the API returns Smart Discovery data that is personalized for the visitor. The possible values are: opt-in: The visitor has opted in to seeing personalized, targeted content. opt-out: The visitor has opted out of seeing personalized, targeted content. Empty: The visitor has not made their profiling choice. The default value is empty. Each visitor's profiling choice is stored in their context. You can get the choice using the frosmo.easy.profile.get() function. note You must always define this parameter on a site that uses selective profiling. Never define this parameter on a site that does not use selective profiling. How the profiling choice works If you set the value to opt-in or empty, the API returns the Smart Discovery data normally. If you set the value to opt-out, the API returns the baseline Smart Discovery data, meaning the platform does not sort the collections in the data based on the visitor's affinities.	String	Optional	profile=opt-out
debug	Define whether to return debugging information about the request. warning Use the debugging information only for development and testing purposes. Do not use the information in production, since Frosmo does not guarantee that the information structure and content will remain the same. The debugging information consists of: Affinity profile of the visitor specified by the cookieId parameter Additional details about the request, such as issues that did not cause the request to fail but that may indicate a problem The possible values are: false: Do not return debugging information. true: Return debugging information. The default value is false.	Boolean	Optional	debug=true

Page context object

The following table describes the page object of the context parameter value. The page object provides contextual information about the page where the API request is made.

Page context object properties

Property	Description	Type	Role	Example
type	Type of the page where the API request is made. The possible values are: brand: The API request is made on a brand page. category: The API request is made on a category page. home: The API request is made on the site home page. note The value must match the page type of the Smart Discovery strategy.	String	Required	"type": "category"
brand	Contextual information about the brand page where the API request is made. This property is required only if the type property is set to brand.	Brand page context object	Required	"brand": { "name": "Wakita" }
category	Contextual information about the category page where the API request is made. This property is required only if the type property is set to category.	Category page context object	Required	"category": { "categories": [ "Fashion/Shoes" ] }

Brand page context object

The following table describes the brand object of the page context object. The brand object provides contextual information about the brand page where the API request is made.

Brand page context object properties

Property	Description	Type	Role	Example
name	Name of the brand. Smart Discovery uses exact matching to check the brand name against brand-based discoveries generated for the site. For example, if the current brand page is Wakita, the API only returns the discovery whose brand name is exactly "Wakita". The API does not return discoveries for, for example, Wakita Industrial or Wakita Tools. For more information about the returned data, see Responses.	String	Required	"name": "Wakita"

Category page context object

The following table describes the category object of the page context object. The category object provides contextual information about the category page where the API request is made.

Category page context object properties

Property	Description	Type	Role	Example
categories	Names of the categories whose items are shown on the category page where the API request is made. Smart Discovery only uses the first name in the array. Make sure the first name is the category whose Smart Discovery data you want to retrieve. Smart Discovery uses "starts with" partial matching to check the category name against category-based discoveries generated for the site. For example: If the current category page is Fashion, the API returns all discoveries whose category name starts with "Fashion", such as Fashion, Fashion/Shoes, and Fashion/Shoes/Sneakers. If the current category page is Fashion/Shoes, the API returns all discoveries whose category name starts with "Fashion/Shoes", such as Fashion/Shoes and Fashion/Shoes/Sneakers. For more information about the returned data, see Responses.	Array of strings	Required	"categories": [ "Fashion/Shoes" ]

Responses

Success

On a success, the Smart Discovery API returns the requested Smart Discovery data in a JSON object. The response status code is 200.

The response object contains the following root properties:

• data: Smart Discovery data as an array of objects, where each object contains the details of a single Smart Discovery. Each object contains the following properties:

  • pageType: Type of the page whose Smart Discovery data was returned.

  • attributeValue: Name of the brand or category whose Smart Discovery data was returned. The name matches the name passed in the corresponding page context object. If pageType is home, the value is empty.

  • items: Smart Discovery data as an array of objects, where each object contains the details of a single Smart Discovery collection. The collections are in descending order of relevance (as determined by item popularity and the visitor's affinities). Use the details to build and render the individual collections in a Smart Discovery web page element.

    note

    For categories:

    • If the category name passed in the category page context object matched a single discovery, the data contains the collections from that discovery.

    • If the category name passed in the category page context object matched multiple discoveries, the data contains the collections from all the discoveries ranked by weight and with duplicate collections removed.

    note

    If two collections have the same image value, the API considers them duplicates and removes the collection with the lower weight (a measure of item popularity).

• user: Object containing visitor information e.g. the visitor's decile or whether the visitor is in the comparison group.

• debug: Object containing the debugging information. This property is included only when the debug parameter is set to true in the request.
