# Authentication

Learn how to authenticate the use of Whisk API services.

At Whisk, we provide you token based access to our API for integration. Here are the different token types that we support:

{% content-ref url="/pages/-M3S3x0gnNBHS\_hNuX-6" %}
[User Access Token](/api-overview/auth/user-access-token.md)
{% endcontent-ref %}

{% content-ref url="/pages/-M3S3x0idyBk8bk53kM4" %}
[Server Token](/api-overview/auth/server-token.md)
{% endcontent-ref %}

{% content-ref url="/pages/-M3S3x0hW7Me1wpFiEx0" %}
[Client Token](/api-overview/auth/client-token.md)
{% endcontent-ref %}

In this API reference documentation, each endpoint description includes information the token type required to access it.
