# PostHog

> Connect PostHog so that the Product analyst reads your product data, and Customers reads what users do.

Connect PostHog so that teammates read your events, trends and funnels, and ask questions in HogQL. Customers can also
read what users do in your product from it. Troopy never changes anything in PostHog.

## Before you begin

Owners and admins connect, replace and disconnect a service.

## What Troopy reads, and for what

| Product or teammate | What it reads                                                                                                                  |
| ------------------- | ------------------------------------------------------------------------------------------------------------------------------ |
| The Product analyst | Events, trends and funnels of one project, with HogQL queries.                                                                 |
| Customers           | What each user did, when an owner or admin picks PostHog as a source of use. See [Understand your customers](/docs/customers). |
| Lists of the CRM    | People who signed up, for a list of sign-ups.                                                                                  |

Troopy uses the query endpoint of PostHog only. Your words go into a query as values, never as the text of the query.

## Connect PostHog

1. Open **Settings** > **Apps**, and select the tile of PostHog. Its card opens.
2. Select **Create the key in PostHog**, or **EU cloud** for a project in the EU.
3. PostHog opens with **Query read** ticked. Limit the key to the project that Troopy should read, and create it.
4. Copy the key. It starts with `phx_`.
5. Paste it into the card. If the key reaches more than one project, add the **Project ID**.
6. Select **Connect PostHog**. Troopy finds the US cloud or the EU cloud by itself.

## Replace or disconnect

- **Replace key** puts a new key in the place of the old one.
- **Disconnect** removes the key. The Product analyst can no longer read PostHog.
