User Agent Data

IPWho includes parsed user agent metadata that describes the visitor’s browser, device, operating system, and CPU architecture.

User agent data is useful for:

• Customizing UI based on device or OS
• Detecting older or unsupported browsers
• Optimizing performance for mobile vs. desktop
• Logging client environment information for analytics
• Tailoring experiences for specific platforms

To get the user Agent the user has to pass in the request parameter in the request body

Below is an example of the user agent fields returned by a lookup:
