PALSession

The Programmatic Access Libraries (PAL) are lightweight SDKs that provide discrete access to targeting signals for Google Ad Manager programmatic ads. The PAL SDK allows you to request a "nonce" from Google, to sign DVC requests. A "nonce" is a single encrypted string generated by PAL that should be added to ad requests as the value for the &paln URL parameter. Each new stream request must be accompanied by a newly generated nonce. However, same nonce can be reused for multiple ad requests within the same stream.

Nonce Manager:

The NonceManager manages the nonce for a single nonce request. This allows to update PAL when an impression or click event occurs.

Nonce Request:

The NonceRequest is used to store information about the request for a nonce. Once NonceRequest is built with PALConfiguration data NonceLoader is loaded with the NonceRequest, generates a encrypted String called nonce that can be added to ad requests as the value for the &paln URL parameter.
