About TikTok App ID
TikTok App ID is a unique code that's generated on TikTok Ads Manager. It allows TikTok advertisers to confirm ownership of their apps and control over their data. Once the code is generated, you will need to paste it into your Mobile Measurement Partner (MMP) dashboard to complete the process.
Note: Verification using TikTok App ID is required for some self-serve ad accounts, and recommended for managed ad accounts.
Benefits
TikTok App ID ensures that advertisers have control over their data while also giving access to additional features including:
Using unattributed events for App Activity custom audience creation for App Retargeting campaigns
Using unattributed events for App Retargeting and Dynamic Product Ads (DPA) re-engagement campaigns
Unattributed events are used in optimization models, which helps improve and refine your campaign performance
For some advertisers, verification via TikTok App ID will be required before you can make iOS 15 dedicated campaigns. If you fall into this bucket, you will see an in-product notification guiding you through the process.
