Send messages to Slack channels and DM users from any automation. React to messages, manage channels, upload files, and handle app mentions — all via the Slack Web API.

​
Authentication

Auth type: Bot token (OAuth 2.0) Create a Slack app at api.slack.com/apps. Add bot token scopes: chat:write, chat:write.public, im:write, channels:join, channels:manage, channels:read, reactions:write, files:write. Install the app to your workspace and copy the Bot User OAuth Token (xoxb-...).

​
Triggers

Triggers require configuring Slack Event Subscriptions in your app settings, pointing to your Collabase webhook endpoint.

​
Actions

Use the channel’s ID (e.g. C012AB3CD), not its display name, for reliable delivery. Right-click the channel in Slack → Copy link — the last URL segment is the ID.
