Hello,
URL destinations can be leveraged to send real-time requests for any destination partner which has an endpoint that supports URL requests: https://experienceleague.adobe.com/docs/audience-manager/user-guide/features/destinations/custom-des...
In terms of our server to server destinations (which can be setup via a customer care support ticket), we are capable of exporting any ID types present in your instance.
If you have a specific partner you would like to know more about, I can provide a list of currently supported ID types from our documentation. If you would like to export ID types beyond those which are currently supported, the destination partner would need to be approached to confirm whether or not they're capable of ingesting those IDs.
Best,
Curtis Oliver | Technical Support Engineer
