# Call HTTP Functions

Calls an HTTP function defined on a site. Learn more about [HTTP functions](https://dev.wix.com/docs/develop-websites/articles/coding-with-velo/integrations/exposing-services/about-custom-site-apis.md).

Requests to this endpoint must include an authorization header whose value is an [access token](https://dev.wix.com/docs/rest/app-management/oauth-2/introduction.md) or an [API Key](https://dev.wix.com/docs/rest/articles/getting-started/api-keys.md) . If the site’s HTTP function requires other headers, include those as well.

The HTTP request method for the site’s HTTP function defines which HTTP method to use in your API call. For example, for the HTTP function `get_myFunction`, use the `GET` method.

### Endpoint
`https://www.wixapis.com/velo/v1/http/invoke/{functionName}`

### Path Params
| Name | Type | Description |
| ---- | ---- | ----------- |
| `functionName` | string | Name of the site’s HTTP function without its method prefix. For example, for the HTTP function `get_myFunction`, use `myFunction`. |

### Body Params
Any body parameters supported by the site’s HTTP function. 

### Response Object
The response object from the site’s HTTP function.

### Example: Call a `GET` HTTP function

#### HTTP function defined in **http-functions.js** in the site's backend:
```js
import { ok } from "wix-http-functions";

export function get_respondOk(request) {
 return ok({result: 'Sending a successful response!' });
};
```

#### API call to the HTTP function:
```bash
curl <GET> \
'https://www.wixapis.com/velo/v1/http/invoke/respondOk' \
-H 'Authorization: <AUTH>'
```
