Slack

Send messages, get notified about events, and build interactive bots that keep your team in the loop. Perfect for alerts, daily briefings, and team notifications. Note: Bubble Lab workflows may use AI language models to generate content. AI-generated responses may be inaccurate or incomplete — users should verify outputs independently.

Supported Triggers and Actions

Bubble Lab helps you create workflows that connect your apps to automate repetitive tasks. A trigger is an event that starts a workflow, and an action is an event that can happen during the workflow.

Triggers

Events in Slack that can start your workflow

• Bot Mentioned — Triggers when your bot is mentioned in a channel
• Message Received — Triggers when a new message is posted in a channel

Actions

Things your workflow can do with Slack
