You can upload a Customer File to create a Custom Audience on TikTok Ads Manager. Once uploaded, TikTok will look for users within our ecosystem that match the IDs on the uploaded file. Once matched, a custom audience will be generated and your uploaded file will be promptly deleted.
Some quick guidelines to create a Custom Audience from a Customer File:
Ensure the file is in a .csv or .txt format and that each device identifier is on a new line or separated by commas. Make sure your prepared file has a header row for the identifer (Email, Phone or MAID). The file should not be larger than 1 GB.
IDFA and GAID can be combined in the same file, but the captilization should be consistent.
MD5 and SHA256 encryption is supported. The content of the file before encryption needs to be in all uppercase or lowercase.
