Connect Slack

  1. Go to Settings → Apps in Hyper
  2. Select Slack → Connect New
  3. Approve requested scopes and choose the workspace

​
Common capabilities

  • Post messages and threads
  • Fetch channel history and files (per permissions)
  • Drive agent handoffs and approvals from Slack

​
Use in Chat

Enable Slack in the tool selector to let agents read or post updates directly from conversations.

​
Use in Agents

Add Slack to an agent’s toolkits, choose a connection, and require approval for posting in designated channels if desired.

​
Use in Flows

Add Slack nodes for notifications, approvals, and escalations. Combine with Gmail/CRM steps for end‑to‑end workflows.

​
Troubleshooting

  • Not posting: verify channel permissions and bot membership
  • Missing history: check scope coverage and private channel access

​
