Question 1

What can I sync from Snowflake into TikTok Ads?

Accepted Answer

Custom audiences and offline conversion events. For audiences, each row in your Snowflake model becomes a member, matched on email or phone number. For conversions, you can report events that happened outside TikTok, which is how you tell the platform about a sale that completed in your billing system rather than on a landing page.

Question 2

How many people do I need for a TikTok custom audience?

Accepted Answer

TikTok documents and enforces a minimum of 1,000 members in its interface for an audience to be usable. In testing the API itself has accepted much smaller audiences, but you should plan around the documented minimum rather than the observed one. Two other limits are worth knowing: processing membership has a 48 hour service level, so a fresh audience is not instantly usable, and an advertiser is capped at 400 audiences.

Question 3

Does Polytomic hash identifiers before sending them to TikTok?

Accepted Answer

Yes. Email addresses and phone numbers are hashed by Polytomic before transmission rather than being sent raw for TikTok to hash. Plaintext values in your model are fine, since they get hashed on the way out, and values you have already hashed are generally passed through unchanged. That means you keep the matching behaviour without raw personal data leaving your systems in the clear.

Question 4

Can Polytomic remove people from a TikTok audience automatically?

Accepted Answer

You can remove people, but not automatically as a mirror of your model. Add mode is add only and remove mode takes members out, and both are available here. What TikTok does not expose in this connector is a mirror mode that reconciles membership for you, which Meta and Microsoft both offer. In practice that means if you want a shrinking audience, model the removals explicitly and run a remove sync rather than expecting membership to self correct.

Question 5

Why use reverse ETL to build TikTok audiences?

Accepted Answer

Because the audiences worth building are defined by data TikTok never sees. Your best customers, the people most likely to buy again, or the ones you should stop spending on, are all worked out in your data warehouse from product, billing and CRM data together. Reverse ETL sends that list to TikTok on a schedule and keeps it current, which is also the usual way teams seed lookalike audiences from their strongest customers.
