I've seen that Client Side Target uses a visitor cookie to identify unique users (analytics visitor ID API I believe). Does Server Side Target have a similar capability? If sow how does it work and how could I incorporate it into my Server Side implementation? TIA
We primarily pass the client side values to our backend services who use them in the server side calls. This ensures our client side analytics implementation uses the same values as Target. This can be done by extracting ECID, AAM Blob and Location Hint from the AMCV cookie.
I don't know Pedro but he has written some great stuff about server side as well that we found while doing our implementation. I think you'll also find them valuable:
We are exploring ways to do this in the App where cookies are not as transferrable.
