Adding Unknown User Data To An Existing User
- Add the Sailthru Javascript – See Personalization Engine Setup. If you are using Site Personalization Manager, see SPM Implementation.
- Data Collection – An existing user browses your site without logging in. The cookie sailthru_cid collects data regarding their visit.
- Pass Information – When the user is logging in, include the cookie in the User API call to update the user profile. For example:
{ "id": "joe@example.com", "login": { "site": "main", "ip": "127.0.0.1", "user_agent": "Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A543a Safari/419.3" }, "cookies": { "sailthru_cid": "U9JEVqLefidFAAAA" } }
user POST (JSON)
Note: A best practice is to code instructions to clear the sailthru_cid after each user POST to an existing user. Failure to do so will result in duplicate sailthru_cid values.
