hi ​@CameronTo,

Looks like a validation failure from TikTok side, can you share a bit more details on the attributes you can activating and the type of audience (Person, Account, Prospects or Custom).

Regards,

I am looking to pass through person accounts using just one attribute which is sha256 hashed email

That looks to be correct, could you validate incase if you are double hashing your email address or not during the destination mapping configuration. 

And when you say person accounts I assume your audience is at : xdm:individual-profile level and not b2b account level.
