Step-by-Step Setup Guide
Building Your First Slack Bot
1
Create a New Lindy
Start by creating a new agent specifically for Slack automation.

Add Slack Message Trigger
Click on “Select Trigger” and choose “Slack Message Received” from the list of available triggers. This will make your bot wake up whenever a message is posted in your Slack workspace.In the trigger configuration:

- Direct Messages: Enable if you want the bot to respond to private messages
- Integration Setup: Authorize your Slack workspace by clicking “Connect” and following the OAuth flow

Set Up Filters (Optional)
Add trigger filters to control when your bot responds and avoid unnecessary activations:Filter by Keywords : Set the bot to only trigger when messages contain specific words

- Useful to prevent the bot from responding to other bots or specific users
- Example: Exclude #random or #general but include #support
4
Add Conditions
Click the ”+” button and select “Condition” to create smart routing logic that determines when your bot should actually respond:Example Conditions:
- “the message contains a question about company policies or procedures”
- “the user is asking for help with our product or service”
- “the message is a support request that needs immediate attention”
