Parameter Description
indexName
type: string
Required

The name of the target index.

objectID
type: string

The objectID of the item to get recommendations for.

maxRecommendations
type: number

The number of recommendations to retrieve. Depending on the available recommendations and the other request parameters, the actual number of hits may be lower than that.

fallbackParameters
type: Omit<SearchParameters, 'page' | 'hitsPerPage' | 'offset' | 'length'>

List of search parameters to send.

Additional filters to use as fallback when there aren’t enough recommendations.

queryParameters

Response

This section shows the JSON response returned by the API. Each API client encapsulates this response inside objects specific to the programming language, so that the actual response might be different. You can view the response by using the getLogs method. Don’t rely on the order of attributes in the response, as JSON doesn’t guarantee the ordering of keys in objects.
