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

Requirements

Using this requires a PostHog Cloud account, access to an active Slack account, and permissions to add the PostHog bot to the Slack workspace and channel.

Installation

1. Create a new destination

First, you need to create a new destination in PostHog that will send the event data to Slack. To do this:

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

2. Click the Destinations tab.

3. Click the + New destination button and search for Slack, then click + Create.

2. Configure a source

Select a source that will trigger messages to be sent to Slack. To do this:

1. Under Source, select if events or person updates will trigger messages to be sent to Slack.
2. Update the filters to specify which events or person updates will trigger messages to be sent to Slack.
3. Update the Trigger options to specify if the messages should be sent immediately or on a schedule.

💡 You can also try clicking the icon to create filters with PostHog AI.

3. Add the PostHog Slack app to your workspace

Next, connect your Slack workspace to PostHog by clicking Choose Slack connection. If you already have a Slack connection, you can select it from the dropdown, and continue to the next step.

If you don't have a Slack connection, you can click Connect to Slack to create a new one. You will be redirected to Slack to install the PostHog app.

The PostHog Slack app will require some basic permissions which you can grant by clicking the Allow button.

4. Add the PostHog Slack app to your channel

You also need to configure which Slack channel will receive the messages from PostHog. To do this, add the PostHog app to the channel you want to send messages to:

1. In the Slack channel header, click the top right menu and click Open channel details
2. Navigate to the Integrations tab
3. Click the Add an app button
4. Under In your workspace, click PostHog

Once you've added the PostHog app to your workspace, you can select it under Channel to post to in the destination editor.

5. Template your message

Finally, you can template your message using Slack's block kit or as a plain text message. You can template the message with the event and person properties using the \{\} syntax. For example:

[
    {
        "text": "Hello, \{person.name\}! You have a new message from \{event.event\}.",
        "type": "mrkdwn"
    }
]

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