PilotLanguages & targeting
Understand current matching and future audience controls.
Current controls
Campaigns specify bot or channel format and a language code. The publisher supplies the language of its placement. This is publisher-provided context, not a verified location or nationality. No language is inferred from a person’s name or writing system.
Planned controls
Country, category, device, frequency limits, publisher exclusions and audience segments need their own data sources and enforcement. They are not active matching rules in this release.
Audience privacy
The current ad request does not require a Telegram user ID. Do not upload lists of users to undocumented endpoints. Audience upload and retargeting have not been released.
