Pathfinder Labs · Synera Add-in
Slack Connector for Synera
Send messages, share images, and receive real-time commands from Slack — all from the visual node graph. Text commands like approve or trigger are parsed into action types for downstream routing.
A Pathfinder Labs add-in for Synera, the low-code engineering platform. Zero-infrastructure event listening — no public URL, port forwarding, or firewall rules.
What the add-in does
Zero-infrastructure event listening
Socket Mode opens an outbound WebSocket to Slack — no public URL, port forwarding, or firewall rules. The Slack Socket Listener node receives @mentions and DMs in real time.
Commands parsed into action types
Incoming messages are classified into Query, Trigger, Approve, Reject, ReRun, Summarize, and ModifyParameter for downstream routing in your graph.
Post text and images
Send plain messages with the Slack Post node, or attach PNG / JPG renders, plots, and screenshots with Slack Image Post — both with toggle-controlled delivery.
User & channel name resolution
Workspace channels and users are resolved by name and cached, so downstream nodes can address #general or @username without juggling Slack IDs.
Configurable channel filtering
Restrict the Socket Listener to a specific set of channels so workflow events only fire for traffic that matters.
Multi-workspace, secrets masked
Connect to multiple Slack workspaces side by side. Bot tokens, signing secrets, and app-level tokens are masked in the Settings UI after saving.
Nodes included
Three node groups, drag-and-droppable into any Synera workflow.
Slack \ Connection
- Synera Slackbot Creator Guided Slack App setup with a pre-filled manifest, OAuth scopes, and App-Level Token configuration. Walks through Slack's developer portal step by step.
- Slack Connector OAuth 2.0 authentication with encrypted token storage (Windows DPAPI). Supports multiple workspaces from a single graph.
- Slack Channels Fetch and cache the workspace's channel list for use by downstream Slack nodes.
Slack \ Messaging
- Slack Post Send a text message to any channel — with toggle-controlled delivery so workflow runs do not accidentally spam Slack.
- Slack Image Post Send a message with an attached image (PNG, JPG, etc.) — designed for sharing plots, renders, and screenshots from upstream nodes.
Slack \ Events
- Slack Socket Listener Receive @mentions, DMs, and text commands via Socket Mode WebSocket. Parses incoming messages into action types — Query, Trigger, Approve, Reject, ReRun, Summarize, ModifyParameter — for downstream routing.
How your data is handled
- The add-in runs entirely on the end user's Windows PC. Pathfinder Labs operates no server that receives, stores, or processes Slack messages, OAuth tokens, or workspace credentials.
- OAuth bot tokens and app-level tokens are stored locally at
%LOCALAPPDATA%\Synera\SlackConnector\tokens.dat, encrypted at rest using the Windows Data Protection API (DPAPI), scoped to the current Windows user account. - Socket Mode means the add-in opens an outbound WebSocket to Slack to receive events — no inbound public URL, no port forwarding, no firewall rules to maintain.
- Slack message contents pass through the add-in in memory to service the workflow node that requested them; nothing is persisted by Slack Connector after the node completes.
- Bot tokens, signing secrets, and app-level tokens are masked in the Settings UI after the first save, so they do not appear on screen during routine workflow editing.
How to revoke access
Slack workspace
A workspace owner can revoke the bot at Settings & administration → Manage apps, or directly on the Slack App page in the Slack developer portal. Tokens are invalidated immediately.
Delete local token store
Delete %LOCALAPPDATA%\Synera\SlackConnector\ to remove all locally-cached, DPAPI-encrypted tokens. Uninstalling the add-in does the same.
