post https://a.klaviyo.com/client/profiles/
Create and update properties about a profile without tracking an associated event.
This endpoint is specifically designed to be called from publicly-browseable, client-side environments only. To create profiles from server applications (e.g. custom server-side scripts / applications), please use POST /api/profiles
Note that to update a profile's existing identifiers (e.g., email), you must use a server-side endpoint authenticated by a private API key. Attempts to do so via client-side endpoints will return a 202, however the identifier field(s) will not be updated.
