Overview

Phinite’s Slack predefined tool lets workspace assistants call Slack APIs through DevStudio after you save a connection under Integrations → Predefined tools. Send and manage Slack messages, reactions, channels, users, scheduled messages, and pins via the Slack Web API.
Predefined tools require a saved connection before they appear in Graph Studio’s tool picker. See Predefined Tools in GraphStudio.

  • Use separate connections for Dev, UAT, and Prod environments where possible
  • Test with a minimal subtool call after saving credentials
