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](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.

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

## Configuration

| Option | Type | Required |
| --- | --- | --- |
| `API key` | password | Yes |
| `Tenant ID (optional)` | text | No |

## Supported tables

| Table | Description | Sync method | Incremental field | Primary key |
| --- | --- | --- | --- | --- |
| `assets` | Individual tracked IT assets (hardware) in BlueTally, including their lifecycle dates, assignment, and related catalog references. | Full refresh | — | id |
| `accessories` | Accessories (peripherals and other non-serialized hardware) tracked by quantity in BlueTally. | Full refresh | — | id |
| `components` | Components tracked in BlueTally that can be checked out to assets (e.g. RAM, drives). | Full refresh | — | id |
| `consumables` | Consumable items tracked by quantity in BlueTally (e.g. cables, ink) that deplete as they are checked out. | Full refresh | — | id |
| `licenses` | Software licenses tracked in BlueTally, including seat counts and assignment. | Full refresh | — | id |
| `employees` | People in BlueTally that assets, accessories, consumables, and licenses can be checked out to. | Full refresh | — | id |
| `products` | Product models in BlueTally's catalog that assets are instances of. | Full refresh | — | id |
| `categories` | Categories used to group BlueTally assets, accessories, and other items. | Full refresh | — | id |
| `manufacturers` | Manufacturers referenced by BlueTally assets, products, and licenses. | Full refresh | — | id |
| `suppliers` | Suppliers that BlueTally assets and other items were purchased from. | Full refresh | — | id |
| `locations` | Physical locations where BlueTally assets and employees are based. | Full refresh | — | id |
| `departments` | Organizational departments used to group BlueTally assets and employees. | Full refresh | — | id |
| `statuses` | Status labels (e.g. Deployable, Archived) that BlueTally assets can be assigned. | Full refresh | — | id |
| `depreciations` | Depreciation schedules applied to BlueTally assets, licenses, and products. | Full refresh | — | id |
| `maintenances` | Maintenance records logged against BlueTally assets. | Full refresh | — | id |
| `audits` | Asset audit records in BlueTally, tracking scheduled and completed audits. | Full refresh | — | id |
| `activity` | Activity log entries in BlueTally: the create, update, delete, check-in, check-out, schedule, complete and recover events recorded against assets, accessories, components, consumables, licenses, maintenances and audits. | Full refresh | — | timestamp, type, event, item\_id, user\_id |
| `tenants` | Tenants the API key can act on. Only populated for BlueTally accounts with multi-tenancy enabled; the tenant ID scopes every other table. | Full refresh | — | tenant\_id |

## 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](https://posthog.com/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.
