If you’re using PostHog to monitor user behavior and product analytics, the PostHog Slack integration is a powerful way to stay informed in real time. In this step-by-step guide, you’ll learn how to send event alerts from PostHog directly to a Slack channel.
Quick answer
To send PostHog event alerts to Slack, go to Settings > Integrations > Slack Integration and click Connect. Then create Slack as a destination, configure event matchers and trigger options, select a workspace and channel, and test and enable notifications.
Requirements
Before you begin, make sure you have the following:
- A PostHog account with the necessary permissions
- Access to a Slack workspace
- If you still need to install PostHog on WordPress, start with our WordPress installation guide.
To start your PostHog Slack integration, navigate to Settings > Integrations > Slack Integration, then click the Connect button to begin the setup.
Step 1: Create a Slack Channel and Invite PostHog Bot
In your Slack workspace:
- Create or choose a channel where you’d like to receive the notifications.
- In the channel, type the following command to invite the PostHog bot: /invite @PostHog
Step 2: Set Up Slack as a Destination in PostHog
- Log in to your PostHog dashboard.
- From the left sidebar, go to Data pipelines.
- Click the New button and select Destination from the dropdown.
- On the “New Destination” page, browse the list of available integrations.
- Find Slack and click Create.
Step 3: Configure Slack and Define Event Matchers
Fill out the configuration form:
- Name & Description: Use clear and descriptive labels (e.g., “Slack Event Alerts”).
- Filter out internal and test users: Enable this option to avoid noise from test data.
- Filters: Use the Add filter button to target specific event properties.
- Match event and actions: Click Add event matcher, then select the event or action that should trigger the Slack notification.
- Trigger options: Set how often notifications should be sent (e.g., once per minute or once per day) based on your monitoring needs.
Step 4: Connect to Slack Workspace
- Choose your Slack workspace.
- From the dropdown, select the specific Slack channel where you want alerts to be posted.
Step 5: Test and Enable Notifications
- Click the Start testing button to verify that your event setup works correctly. For a deeper check, use our PostHog audit.
- Once everything is configured properly, you’ll then see a sample notification sent directly to your selected Slack channel, just as it will appear during actual use.
Once the test is successful, click Create and enable to activate the integration.
