Hey @R&B Silva

Could you please check in your supergroup whether the bot is active in your group or not?

And pass the username of the target channel (in the format @channelusername, or @supergroupusername)

(Watch the second part of the video)

R&B Silva

I'm doing exactly as in the videos, the bot is added to the group as admin and the error persists.

Because it's a private group, I don't know how to find @channel

R&B Silva

I change to public group and I try with @supergroupusername and the error persists. I try to create another bots, I dont know what's the problem.
Hey @Supreme, help-me 🙏
I need to finish this today or I will do this manually in my product launch 😢

🔴 More informations:
When I use the automation to send a text in the group, everything works well, but if I try to create a link... "bad request: chat_id is empty"

Finally I solve this problem, I need to put a Expiry Data. Can you say if is possible to create a link without expiry date?
