What is the difference between Admin or Non Admin Group?

Hi @horacechan,

Normally this error comes up when the group ID is changed due to the conversion into a supergroup. As this happens automatically when you give users admin rights you'll need to reselect the Chat Id in the Telegram action step.

Additionally, I’m not really familiar with Telegram groups that much. However, I found this blog from Telegram that refers about admins and supergroups: https://telegram.org/blog/supergroups?setln=en

Hopefully, this helps.

I want to know - what is the difference between Supergroup or Normal Group

Normal groups support up to 200 members while supergroups can have 200,000. supergroups also offer features like message pinning and better moderation, great thing for large communities.

My question is - can i link the same telegram bot to both 1 and 2 at the same time?

(1) zapier with super group (2) zapier with normal group 

Yeah, you can link the same telegram bot to both a supergroup and a normal group. Just add the bot to both groups and set up separate zaps for each.
