​
Examples

public class Product
{
    public string ObjectID { get; set; }
    public string Name { get; set; }
    public string Category { get; set; }
    public float Price { get; set; }
}

public class RecommendedProduct : Product, Algolia.Search.Models.Recommend.IRecommendHit
{
    public float Score { get; set; }
}

var requests = new List<Algolia.Search.Models.Recommend.BoughtTogetherRequest> {
  new Algolia.Search.Models.Recommend.BoughtTogetherRequest {
      IndexName = "your_index_name",
      ObjectID = "your_object_id",
  }
}

var recommendations =
  recommendClient.GetFrequentlyBoughtTogether<RecommendedProduct>(requests);

// Asynchronous
var recommendations =
  await recommendClient.GetFrequentlyBoughtTogetherAsync<RecommendedProduct>(requests);

Response as JSON

This section shows the JSON response returned by the API. Each API client wraps this response in language-specific objects, so the structure may vary. To view the response, use the getLogs method. Don’t rely on the order of properties—JSON objects don’t preserve key order.
