With webhook destinations, you can send event data from PostHog to any HTTP endpoint, whether it's to your own backend, an internal system, or a third-party platform.

**Want to send PostHog data to a particular platform like Slack?**

Browse all the **Destinations** listed in the sidenav to integrate with well-known platforms like [Slack](https://posthog.com/docs/data-pipelines/destinations/slack.md), [HubSpot](https://posthog.com/docs/data-pipelines/destinations/hubspot.md), or [Zapier](https://posthog.com/docs/data-pipelines/destinations/zapier.md).

## Setting up destination webhooks

### 1\. Create a new destination

In PostHog, navigate to the [data pipelines](https://app.posthog.com/data-management/destinations) section in the sidebar. Click **\+ New** > **Destination** in the top-right corner. Search for "Webhook" then click **\+ Create**.

### 2\. Configure the webhook

On the configuration page, enter a **Webhook URL**. This is the HTTP endpoint that will receive the event data from PostHog. By default, PostHog sends a `POST` request with a templated JSON body.

Click **Create & Enable**.

**Webhook services**

You can use services like [webhook.site](https://webhook.site/) or [ngrok](https://ngrok.com/) to create **Webhook URLs** for quick testing.

### 3\. Test the webhook

Now that the webhook is enabled, let's see it in action. In the **Testing** section of the configuration page, click **Start testing** > **Test function** to send an example event.

You should see the webhook endpoint receive a `POST` request with event data.

**Debugging**

Try enabling **Log responses** to help debug HTTP calls.

### 4\. Customize the webhook (optional)

You can further configure and customize webhook destinations by:

-   Adding filters, match rules, and trigger options in the **Filters** section
-   Customizing the [payload](https://posthog.com/docs/data-pipelines/destinations/customizing-destinations.md#customizing-payload)
-   Using [global variables](https://posthog.com/docs/data-pipelines/destinations/customizing-destinations.md#global-object)
-   Modifying the [source code](https://posthog.com/docs/data-pipelines/destinations/customizing-destinations.md#modifying-destinations-with-hog) in the **Edit source** section

## Configuration

**Add IPs to Firewall/WAF allowlists (recommended)**

If your webhook endpoint is behind a firewall or web application firewall (WAF), it may block requests from PostHog. Add these IP addresses to your allowlist so PostHog can deliver events to your endpoint.

**EU**: `3.75.65.221`, `18.197.246.42`, `3.120.223.253`

**US**: `44.205.89.55`, `52.4.194.122`, `44.208.188.173`

These are public, stable IPs used by PostHog's data pipeline.
