Hi,

We have old API https://a.klaviyo.com/api/v2/people/exchange

to get profileID from exchange_id

is this supported in new API already?

I have user exchange_id from cookie and I’d like to get profile_id from klaviyo ~ server-side.

Is it possible?

Hey Yukkon,

I’d be interested to hear what use-case you were working on here?

I ran into this issue with the new API when attempting to implement Klaviyo cross-domain tracking (where you append the _kx parameter to links to sub-domains, for eample), but managed to eventually find a working solution.

Hi ​@ross_hopkins would you mind sharing your solution for cross domain tracking and the new Klaviyo library?

Thanks
