Hi @GGilyov!

Yep, you can use different accounts within the Same Slack space, in the same or different channels. You can also use connect different Slack accounts within the same Zapier account by adding them in My Apps or when you build the Zap. Each connected Slack account will have the permissions for that account, which Slack administrators can set. 

​I hope that's clear, please let us know if you have any questions!
