# About Headless Projects

[Wix Headless](https://dev.wix.com/docs/go-headless/get-started/about-headless/about-wix-headless.md) enables you to take advantage of Wix's business management platform from any app or site you create, on any platform.

For example, you can create a site's frontend using any framework and use Wix Headless to handle the site's blog, CRM, and product catalog.

## Which APIs to use

The APIs you should use depend on the language you're using to develop your Headless project:

- If you're developing in a JavaScript or TypeScript environment, use the [Wix JavaScript SDK](https://dev.wix.com/docs/sdk.md).
- For all other environments, use the [Wix REST APIs](https://dev.wix.com/docs/rest.md).

> **Note:** Frontend SDK modules aren't supported for use in Headless projects.

## Authentication and client setup

The authentication method for a Headless project depends on which API you use:

- If you use the Wix JavaScript SDK, you can:
  - [Create a client with the OAuth authentication strategy](https://dev.wix.com/docs/go-headless/coding/java-script-sdk/visitors-and-members/create-a-client-with-oauth.md) to make API calls on behalf of visitors and members.
  - [Create a client with API key authentication strategy](https://dev.wix.com/docs/go-headless/coding/java-script-sdk/admin/create-a-client-with-an-api-key.md) to perform administrative operations.
- If you use the REST API, you can:
  - [Use OAuth tokens for authentication of API calls](https://dev.wix.com/docs/go-headless/coding/rest-api/visitors-and-members/make-api-calls-with-oauth.md) on behalf of visitors and members.
  - [Use an API key for authentication of API calls](https://dev.wix.com/docs/go-headless/coding/rest-api/admin/make-api-calls-with-an-api-key.md) that perform administrative operations.

## Templates and tutorials

Templates and tutorials for headless projects are available in the [Wix Headless portal](https://dev.wix.com/docs/go-headless/get-started/about-headless/about-wix-headless.md).
