iFrame Usage

If the DeviceAssure library is embedded in a cross-origin iframe, the following attributes are required to suppress warnings in the console. The library will continue to work, the errors/warnings are non-blocking in the library.

allow="accelerometer; gyroscope;"

Content Security Policy (CSP)

If your site uses a Content Security Policy, the DeviceAssure API URLs may need to be added to the connect-src directive:

Content-Security-Policy: connect-src 'self' https://api1.devicevalidation.io https://api2.devicevalidation.io https://api3.devicevalidation.io;

Note: If you are also using QR Code functionality, additional domains are required for frame-src and script-src.
