Enable Luna Slack messaging
For Luna to send messages and hold conversations with employees in Slack, you need to set up the Slack Communications Channel. This is a separate configuration from the main Slack integration used for access management—you can have one without the other.
If Luna replies aren't working in Slack, it's likely the communications channel hasn't been set up. The regular Slack integration alone doesn't enable Luna messaging.
Set up the Slack Communications Channel
Navigate to Integrations in your Ploy dashboard: https://app.joinploy.com/integrations
Click the Channels tab
Find the Slack card and click Connect
Authenticate with Slack via OAuth—this installs the Ploy bot into your Slack workspace
Enter your Slack workspace domain (just the subdomain, e.g.,
mycompanyif your workspace ismycompany.slack.com)Toggle the channel On
Once connected, Luna can initiate conversations with employees in Slack and receive their replies in-thread—the bot handles the back-and-forth automatically.
Prerequisites
Slack workspace admin access: You'll need admin permissions (or an admin on hand) to authorize the Ploy bot installation during OAuth
Channel invitations: The bot must be invited to any Slack channels where it will message employees. Slack will prompt for this during the OAuth flow, but if you encounter delivery issues later, check that the bot has access to the relevant channels
Enterprise Grid organizations
If your Slack workspace is part of an Enterprise Grid organization, there's an additional toggle during setup. Follow the prompts to complete the enterprise-specific configuration.
