Getting Started - DeviceAtlas for Web

Resources

Follow these simple steps to have the DeviceAtlas Enterprise API working locally within a few minutes.
If you do not have a licence, please contact us to request an evaluation.

1. Download Device Data File

For the Enterprise solution, device data is packaged in a JSON format, which is highly compressed to reduce server footprint, and is optimized for speed of search and retrieval. It can either be downloaded manually or fetched with an automated script.

Refer to our Device Data (JSON) reference documentation to know more about DeviceAtlas data downloads.

Download Java DeviceAtlas Enterprise API

Create an API instance and load the data file

DeviceApi deviceApi = new DeviceApi();
deviceApi.loadDataFromFile("/path/to/DeviceAtlas.json");

Detect device properties by HTTP headers

Map<String, String> headers = new HashMap<String, String>();
headers.put("HEADER NAME", "HEADER VALUE");
Properties properties = deviceApi.getProperties(headers);

3. Data File Options

Default data file only has 21 out of 177 properties selected. Please visit Data File Options page to customize which device properties are to be included in data file.

4. Client-side Component

The Client-side Component is needed for granular identification of iOS devices, as well as for other dynamic properties. Please visit DeviceAtlas Client-side Component.
