 **Note**: If a demand partner of Equativ is not capable of reading an audio object, the audio object will be converted into a video object with audio mime types. There is, as of this writing, no built-in/default support for serving audio assets in Prebid, so publishers that wish to do so will need to ensure their ad server setups can process whatever hand-offs are necessary.
 
+### First Party Data
+
+Publishers should use the `ortb2` method of setting [First Party Data](https://docs.prebid.org/features/firstPartyData.html).
