Query Suggestions API (1.0.0)

Download OpenAPI specification:Download

The Query Suggestions API lets you manage your Query Suggestions configurations. Query Suggestions add new indices to your Algolia application with popular search queries, external suggestions, or facet values. In your user interface, you can query the Query Suggestions indices like regular indices and add suggested searches to guide users and speed up their search.

Base URLs

The base URLs for requests to the Query Suggestions API are:

  • https://query-suggestions.us.algolia.com
  • https://query-suggestions.eu.algolia.com

Use the URL that matches your analytics region.

All requests must use HTTPS.

Authentication

To authenticate your API requests, add these headers:

  • x-algolia-application-id. Your Algolia application ID.
  • x-algolia-api-key. An API key with the necessary permissions to make the request. The required access control list (ACL) to make a request is listed in each endpoint's reference.

You can find your application ID and API key in the Algolia dashboard.

Request format

Request bodies must be JSON objects.

Response status and errors

Response bodies are JSON objects. Deleting a user token returns an empty response body with rate-limiting information as headers.

Successful responses return a 2xx status. Client errors return a 4xx status. Server errors are indicated by a 5xx status. Error responses have a message property with more information.

Version

The current version of the Query Suggestions API is version 1, as indicated by the /1/ in each endpoint's URL.
