Channel Access Guide

​

Private Channels

1. You must be a member of the private channel
2. The Gumloop bot must be in the channel

• Private channels won’t appear in the dropdown if you’re not a member, even if the bot is present
• For sensitive automation, use your Personal workspace instead of shared workspaces
• To add the bot, you have two options:
  1. Type /invite @Gumloop in the channel, OR
  2. Click the channel name → Add integrations/Add app → Search for “Gumloop”

​

Public Channels

• All public channels where the Gumloop bot is present will be available
• Add the bot using either:
  • /invite @Gumloop command in the channel
  • Channel name → Add integrations/Add app → Search for “Gumloop”

​

Direct Messages to Users

• You can send direct messages to any user in your Slack organization
• You can toggle between channel and user under Show more options
• The message will be sent from the Gumloop bot to the user
• Note:
  • These messages will not appear in your personal DM history with the user
  • You can only send direct messages to users within your Slack organization, not to external users

​

2. Channel Access: Add Gumloop to channels using /invite @Gumloop
3. Private Channels: Ensure both you and the bot have access
4. DM Behavior: Messages to users come from the Gumloop bot, not your account
5. Available Users: Only users in your Slack organization can receive direct messages
6. Loop Mode: Available for sending multiple messages to different channels or users
