Generate secured API key

Create an API key on your server without any request to Algolia.

This helper method generates a secured API key from a parent API key by adding query parameters and restrictions.

Secured API keys use hash-based message authentication codes (HMAC).

To generate a secured API key, the method performs the following steps:

1. Compute a SHA-256 HMAC with:

   • Secret: the parent API key
   • Message: a URL-encoded list of query parameters

   These query parameters are applied to every request that uses the API key and can’t be modified by end users.

2. Concatenate the SHA-256 HMAC with the list of query parameters into a single string.

3. Encode the resulting string in base64.

Usage

C#

var response = client.GenerateSecuredApiKey(
  "2640659426d5107b6e47d75db9cbaef8",
  new SecuredApiKeyRestrictions
  {
    ValidUntil = 2524604400L,
    RestrictIndices = new List<string> { "Movies" },
  }
);

Parameters

C#

parentApiKey · string · required

The API key to be used as secret for the secured API key. The secured API key inherits all restrictions from its parent. You can’t use an Admin API key as parent.

restriction · SecuredApiKeyRestrictions · required

You must apply at least one restriction when creating a secured API key. If you try to use a secured API key with the same restrictions as its parent key, the API returns a 403 Forbidden error.

SearchParams · SearchParamsObject

Search parameters that are always applied when using this API key. For more information, see API parameters.

Filters · string

Filters that are always applied when using this API key.

ValidUntil · long

Timestamp when the API key expires, in seconds since the Unix epoch.

RestrictIndices · List<string>

Indices names that this API key can access. Use * as a wildcard, for example dev_* to allow all indices with names that start with dev_.

RestrictSources · string

IP network range that is allowed to use this API key.

UserToken · string

By default, rate limits are applied per IP address. If many users share an IP, add a user token to each generated API key to avoid incorrect rate limiting.
