**Alpha release**

This source is currently in **alpha**. The interface and available tables may change.

The Alguna connector syncs your billing and CPQ data – customers, invoices, subscriptions, payments, refunds, plans, products, and billable metrics – into PostHog, so you can join revenue data with product analytics.

## Prerequisites

You need an [Alguna](https://alguna.com) account with access to API credentials. API keys are issued in the Alguna dashboard under **Settings** > **Credentials**.

## 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 Alguna, you'll need:

-   **API key** – create one under **Settings → Credentials** in your [Alguna](https://alguna.com) dashboard. The key has read access to your workspace's billing data.

## 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](/docs/cdp/sources.md#sync-methods) for a full explanation of how each mode works and how to choose between them.

All Alguna tables sync as full refresh. Billing entities are low volume, so a full reload on each sync stays cheap and always reflects deletions.
