The Chargebee connector syncs your billing data – customers, subscriptions, invoices, events, and more – into PostHog, so you can analyze revenue and billing activity alongside your product data.

## Prerequisites

You need a Chargebee account and a read-only API key. We recommend creating a dedicated read-only key for this integration.

## Adding a data source

1.  In PostHog, go to the [Sources tab](https://app.posthog.com/data-management/sources) of the data pipeline section.
2.  Click **\+ New source** and click **Link** next to this source.
3.  Enter your credentials (see [Configuration](#configuration) below) and click **Next**.
4.  Select the tables you want to sync, choose a sync method and frequency, then click **Import**.

Once the syncs are complete, you can start querying this data in PostHog.

When linking Chargebee, you'll need:

-   **API key** – in your Chargebee dashboard, go to **Settings > Configure Chargebee > API keys**, then click **\+ Add API Key** and select **Read-Only Key**. Copy the value of the newly created key.
-   **Site name (subdomain)** – found in the top-left of your dashboard. It's the same as the subdomain of your dashboard (the part before `.chargebee.com`).

## Sync modes

Each table can be synced in one of several modes, depending on what the source supports:

-   **Webhook** (when available) – the source pushes changes to PostHog in real time. Fastest freshness, lowest ongoing cost, and the only mode that reliably captures updates and deletes.
-   **Incremental** – only new or updated rows are synced on each run, using a cursor field (such as an `updated_at` timestamp). Cheaper than a full refresh, but deletes aren't captured.
-   **Append only** – new rows are appended using a cursor field; existing rows are never updated. Ideal for immutable, append-only tables like event logs.
-   **Full refresh** – the whole table is reloaded on every sync. Use it when a table has no reliable cursor or when you need deletions reflected.

See [sync methods](https://posthog.com/docs/data-pipelines/sources.md#sync-methods) for a full explanation of how each mode works and how to choose between them.
