is it possible to write cookies to users using DIL integration on our website via setting cookie destination on segment which contains users from onboarded trait under cross device type data source? Because we are unable to write cookies for such use case, however we have no problems to write cookies if we set up a same cookie destination on different segment containing rule-based trait under cookie type data source.
Are there any limitations for writing cookies using cookie destination ?
A cookie destination returns and writes data to a cookie in the user's browser only when user gets qualified for the mapped segment. Until and unless user gets qualified for the segment, it is not possible retrieve segment information.
For onboarded trait,we need to make sure that user data which is uploaded in audience manager are visiting the web site again, so that they can be part of real time segment population.
yes of course you are right, we are aware of it and when we tested it, we made sure that we uploaded CRM data for particular customers on which we tested writing cookies afterwards. We also checked that those customers were at that time qualified for segment containing cookie destination setup via Visitor profile viewer.
