There are two ways to update user traits via Tracking API:
- as part of the "Identify"- method
- with the "Update"- method (only regular tracking, not mobile tracking)
In both cases you only need to add the "traits"-array to the API call that includes all traits that need to get updated.
Excample:
{
"xngGlobalUserId":"56409f54-aceb-48a3-91de-5fdc1d6e7aad",
"userId":"kb_1",
"type":"identify",
"traits":{
"bla":"blubb"
}
}
