When you’re setting up your campaign on TikTok ads, the general best practice is to exclude a list of previous purchases. There are two ways to do it (on Facebook or Google ads):
- Exclude via Google/Facebook pixel
- Manually upload a .csv list of your Shopify customers
Our software, Lebesgue: Smarter Marketing, revolves around the precise exclusion of these customers:
- Automated Advertising Audit will detect if you’re not excluding audiences properly
- Market Intelligence gives you benchmarks for Prospecting and Retargeting audiences
- AI Copywriter optimizes written copy for Prospecting campaigns
Uploading a custom audience for TikTok
However, when you try to upload a custom audience to TikTok, you’ll first see a message:
“Due to Apple’s App Tracking Transparency framework, there may be fewer or no matches for IDFA, email and phone files.”
After that, you need to select one of the following types:
- IDFA/GAID – Original Value
- IDFA/GAID – MD5 Hashed
- IDFA/GAID – SHA265 Hashed
You’ll see two additional notes:
- Please put each identifier on a new line.
- Please confirm you are uploading a IDFA/GAID Original Value file.
In addition, you will get the “You have less than 1,000 pieces of valid data in your file. Please check the data type and formatting” message.
In our case, we tried uploading 30,000 contacts a from Shopify store, but it turned out to be impossible to do it. We also tried uploading different data formats, formatting email addresses to UPPERCASE or lowercase – nothing worked.
Check out the image bellow:

This is the current state of TikTok ads – you can’t upload a customer list from your Shopify store to TikTok.
Alternative way to upload your list
There is one workaround, but it’s not one you’ll like. If you have a TikTok account manager, they’re able to do some backend magic and upload list of your customers for you. This might also be important for your Lookalike audiences, which perform better on TikTok than they do on Facebook ads at the moment.
If you don’t have a TikTok account manager – you can reach out to the Lebesgue team via email or chat, and we’ll see if we can help you pass this info further.
