**Alpha release**

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

The BlueTally connector syncs your IT asset management data into PostHog, so you can analyze your assets alongside your product data.

## Prerequisites

You need a BlueTally account with access to create an API key.

## 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 BlueTally, you'll need:

-   **API key** – create one in BlueTally under **Settings → API Keys**, then paste it here.
-   **Tenant ID** – optional. If your account has multi-tenancy enabled, enter the tenant ID the key should act on.

## 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.

BlueTally exposes no server-side timestamp filter, so this source is full refresh only.

## Troubleshooting

-   If you see an authentication error, your API key may be invalid or expired. Create a new key under **Settings → API Keys** in BlueTally, then reconnect.
-   If you see a permission error, check that the key has permission to read the data you want to sync.

If your sync is failing or data looks wrong, see the [Data warehouse troubleshooting guide](/docs/data-warehouse/troubleshooting.md). If that doesn't help, [contact support](https://us.posthog.com/#panel=support%3Asupport%3Adata_warehouse%3A%3Atrue) – we're happy to help.
