51Degrees Device Detection Python  4.1

Device Detection services for 51Degrees Pipeline
Search

cloud/metadata.py

This example shows how to retrieve property meta data from the 51Degrees cloud service. This feature can be used to get information such as the category that a property belongs to or the possible values a property can have. (At the time of the request. If the data file being used by the cloud service is updated, the possible values for a property can change)

To run this example, you will need to create a resource key. The resource key is used as shorthand to store the particular set of properties you are interested in as well as any associated license keys that entitle you to increased request limits and/or paid-for properties.

You can create a resource key using the 51Degrees Configurator.
