# HTTP
The HTTP channel is useful for pushing your Shopify orders to a REST API, a GraphQL interface, or a SOAP web service.
### URL
The first step is to specify the target URL.
You can include [Liquid variables](https://help.exporteo.solvenium.com/liquid/liquid-variables) in the URL. For example, to pass the order number in the path, set the URL to:
```
https://api.example.com/orders/{{order.order_number}}
```
A special Liquid variable for the URL field is the `{{output}}` variable which stores the entire content generated from the output template. It can be useful in rare cases when a web service accepts data only through the query parameters.
```
https://ecommerce.gardenimpressions.nl/webservices/garden-mkpprod/PutOrder?XMLTEXT={{output | url_encode}}
```
### Method
You can select one of the following HTTP methods: GET, POST, or PUT.
In most cases, the desired method is POST.
For POST and PUT methods, the generated output is passed in the request payload body.
### Headers
HTTP headers are pieces of information that are sent along with the main payload. An HTTP header consist of a key (a fixed name), and value. One of the most popular headers is `Content-Type`. The `Content-Type` header is automatically added by Exporteo, and changes according to the selected output format.
| Output Format | Content-Type |
| ------------- | ---------------- |
| CSV | text/csv |
| JSON | application/json |
| XML | application/xml |
However, you may need to adjust the `Content-Type` header for the XML output formats, as some web services require `text/xml` instead of `application/xml`.
