About this method

Generate a secured API key without any call to Algolia’s servers.

When you need to restrict the scope of an API key, use secured API keys. You can only generate a secured API key from your search-only API keys: you can’t use Admin API keys, or other secured API keys.

Don’t generate secured API keys from your frontend. If you do, users can modify the code and remove restrictions, which can expose hidden, sensitive data.

You can define a number of restrictions (such as “valid until” and “restrict indices”).

Keep in mind that the more limitations you set, the longer the key. You might face network limitations with a key longer than 500 characters, so consider this when adding restrictions.

If you want to rate-limit a secured API key, the key that you used to generate it must also be rate-limited. You can create a rate-limited key via the dashboard, or using either the Add API Key or Update API Key methods of an API client.

Parameters

`apiKey`	type: string Required The API key that your new secured API key inherits restrictions from.
`filters`	type: string default: "" Optional Filters that apply to every search made with the secured API key. You can add extra filters at search time with the `filters` query parameter. For example, if you set the filter `group:admin` on your generated API key, and you add `groups:press OR groups:visitors` with the `filters` query parameter, your final search filter is equivalent to `groups:admin AND (groups:press OR groups:visitors)`.
`validUntil`	type: integer default: no expiration date Optional A Unix timestamp used to set the expiration date of the API key.
`restrictIndices`	type: list default: all indices Optional List of index names that can be queried.
`restrictSources`	type: string default: no restricted sources Optional IPv4 network allowed to use the generated key. This is used for more protection against API key leaking and reuse. You can only provide a single source, but you can specify a range of IPs (e.g., `192.168.1.0/24`).
`userToken`	type: string default: users' IP address Optional Specify a unique user identifier. This can be useful when you want impose a rate limit on specific users. By default, rate limits are set based on the IP address. This can become an issue when several users search from the same IP address. To avoid this, you can set a unique `userToken` for each user when generating their API key. This lets you restrict each user to a maximum number of API calls per hour, even if they share their IP with another user. Specifying the `userToken` in a secured API key is also a good security practice as it ensures users don’t change it. Many features like Analytics, Personalization, and Dynamic Re-ranking rely on the authenticity of user identifiers. Setting the `userToken` at the API key-level ensures that downstream services work as expected and prevents abuse.
`searchParameter`	type: key/value mapping default: none Optional A mapping of search parameters applied at query time. If you specify any of the following parameters in both the API key (`A`) and in your search (`B`), they are combined (`A AND B`): `filters` `facetFilters` `optionalFilters` `numericFilters`
