Send PostHog event data to Slack webhooks

Use this destination to send custom messages into Slack based on PostHog events or actions.

If you want to receive regular insight or dashboard subscriptions to Slack, checkout our subscriptions docs.

Requirements

Using this requires either PostHog Cloud, or a self-hosted PostHog instance running a recent version of the Docker image.

You'll also need access to the relevant Slack account.

Installation

1. In PostHog, click the Data pipeline tab in the left sidebar.

2. Click the Destinations tab.

3. Search for Slack and click + Create.

   

4. Choose an existing Slack connection or click Connect to Slack. You will be redirected to Slack to install the PostHog app.

   

5. Make sure the PostHog app has been added to your desired Slack channel. Type the Slash command /invite @PostHog directly in the channel to add the integration.

6. Choose your event or action matching and customize your message using Slack's block kit.

7. When selecting a Slack channel, you can either search for channels by name in the dropdown or paste a channel ID (e.g., C1234567890).

8. Once done, press Create & Enable and watch your messages appear in Slack.
