# Sending a POST request with an XML/JSON data source

With a POST request, you can send XML or JSON data in the request body to an external web service. The XML/JSON data source sends the request and makes the data returned by the service available for further processing in dox42.

The following steps provide only a general overview, as the configuration of a POST request depends on the external web service.

## Prerequisites in dox42

- [You have created a document template](/help/docs/creating-a-document-template).
- [You have created a data map](/help/docs/creating-a-standard-data-map).

## Steps

1. Follow steps 1 to 5 in the article [Importing and structuring flat XML/JSON data](/help/docs/adding-an-xml-json-data-source-to-your-data-map).
2. Select **POST** from the **URL/XML/JSON** dropdown. The **Post Data** button is activated.
3. Enter the URL of the external web service.
4. Select the **Post Data** button. The **Configure Request Body** window opens.
5. Configure the request body as required by the external web service.
6. If required, configure authentication or additional HTTP headers.

## Result

You have configured a POST request that sends data to an external web service and processes the response in the XML/JSON data source.
