why is the telegram ad platform rejecting my sponsored messages with 'invalid channel_id' errors consistently?
been trying to get a couple of sponsored messages approved on the telegram ad platform for our new SaaS offering, but it's proving to be a real headache. i'm consistently hitting a wall with 'invalid channel_id' or 'channel not found' errors, even after double-checking everything. this persistent issue is really slowing down our user acquisition strategy and it feels like some underlying channel verification issues are at play.
to troubleshoot, i've taken several steps:
- verified channel username and numerical ID directly from teh Telegram client, pulling it from the 'info' section.
- ensured the channel is public and explicitly linked to my ad platform account via the proper authorization flow.
- checked admin permissions for the bot or account managing these ads, making sure it has full post and edit rights.
- tried using both the channel username (like @channelname) and the raw numerical ID (e.g., -100xxxxxxxxxx) in the ad creation interface, with no luck.
what are the obscure, technical reasons or common misconfigurations within the telegram ad platform itself that lead to these persistent channel_id validation failures, beyond the obvious checks i've already performed?

Answered 22 hours agoUgh, the 'invalid channel_id' loop on the Telegram Ad Platform is infuriating; I've been there, pulling my hair out over similar channel verification issues. (Psst, you typed 'teh' instead of 'the' once โ easy to do!) Often, even after thorough checks, the core issue is a server-side caching delay on Telegram's platform, or a requirement for the ad account to hold *full ownership* of the channel, not just admin rights, which needs 24-48 hours to fully propagate and align with Telegram advertising policies. Did you recently transfer channel ownership or make it public?
