# CreateAPIKey
<a name="API_CreateAPIKey"></a>

Creates an API key that contains a set of token domains.

API keys are required for the integration of the CAPTCHA API in your JavaScript client applications. The API lets you customize the placement and characteristics of the CAPTCHA puzzle for your end users. For more information about the CAPTCHA JavaScript integration, see [AWS WAF client application integration](https://docs.aws.amazon.com/waf/latest/developerguide/waf-application-integration.html) in the * AWS WAF Developer Guide*.

You can use a single key for up to 5 domains. After you generate a key, you can copy it for use in your JavaScript integration.
