# Custom Site API Calls
Use the [endpoints](#endpoints) below to call your HTTP functions through custom site APIs.

Call these endpoints with the [method](https://dev.wix.com/docs/develop-websites/articles/coding-with-velo/integrations/exposing-services/methods-for-http-functions.md) defined in your HTTP function. 

Make sure to define your [variables](#variables) correctly for the function.

<blockquote class="important">
  <strong>Important:</strong>
  
  The endpoints in this article call custom site APIs without [authentication context](https://dev.wix.com/docs/develop-websites/articles/coding-with-velo/integrations/exposing-services/about-custom-site-apis.md). You can [call your custom site APIs with authentication context](https://dev.wix.com/docs/develop-websites/articles/coding-with-velo/integrations/exposing-services/about-custom-site-apis.md) using the HTTP Functions [REST API](https://dev.wix.com/docs/rest/assets/http-functions/rest/introduction.md) or [SDK module](https://dev.wix.com/docs/sdk/backend-modules/http-functions/functions/introduction.md).
</blockquote>

## Variables
You need to define the following variables to construct your API calls.

### `baseUrl`
The base URL of the site hosting the HTTP functions:
- **Premium sites**: `https://www.<user_domain>`
- **Free sites**: `https://<user_name>.wixsite.com/<site_name>`

> **Note:** The top level domain for free sites may not be `.com`. For example, for UK based sites, it may be `.co.uk`.

### `functionName`
The name of the HTTP function your custom site API calls without its method prefix.

For example, for an HTTP function defined by `export function get_myFunction(request) { }`, the `functionName` is `myFunction`.

## Endpoints
Use the following endpoints to call your custom site APIs.

### Production
Accesses the latest code published to the production site:

`<baseUrl>/_functions/<functionName>`

### Test sites
Accesses the latest code published to a [test site](https://support.wix.com/en/article/about-test-sites):

`<baseUrl>/_functions/<functionName>?rc=test-site`

### Sites using [Git Integration](https://dev.wix.com/docs/develop-websites/articles/workspace-tools/developer-tools/git-integration-wix-cli/about-git-integration-wix-cli.md)
Accesses the code pushed in the specified branch (`branchId`) in the specified commit hash (`revisionNumber`):

`<baseUrl>/_functions/<functionName>?siteRevision=<revisionNumber>&branchId=<branchId>`

### Editor preview
Accesses the latest code in the site editor:

`<baseUrl>/_functions-dev/<functionName>`

> **Note:** You must [create a test site](https://support.wix.com/en/article/test-sites-creating-a-test-site) to use this endpoint.
