Hi @Siya :wave: Is this a private channel, or a group of users you’re trying to message? If it’s a private channel, your bot will need to be added to the channel. If it’s a group message, you may not have the right scopes enabled for your bot.

If that doesn’t fix it up for you, iyou have any examples of what’s working as a message and what doesn’t (without sharing any sensitive information), that would also help!
