any idea, when we can recommend DCS API instead of SSF.
@MA1985v1 See following post: https://www.pedromonjo.com/2018/06/server-side-audience-manager/
DCS API is the original method, created by the AAM development team, before the server-side forwarding was implemented. However, I do not recommend this alternative method, unless you do not have Adobe Analytics.
Hopefully that helps a bit - Let us know!
