**Alpha release**

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

The ElevenLabs connector syncs your AI audio data into the PostHog Data warehouse: speech generation history, conversational AI conversations and agents, voices, and models. Use it to analyze generation volume, character costs, and agent call outcomes alongside your product data.

## Prerequisites

You need an ElevenLabs account with an API key. API keys are available on every plan.

## 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 ElevenLabs, you'll need:

-   **API key** – create one in your ElevenLabs account under [Profile → API keys](https://elevenlabs.io/app/settings/api-keys). If you restrict the key's permissions, grant read access to the endpoints you want to sync: **History**, **Conversational AI**, **Voices**, **Models**, and **User** (used to verify the key).

## 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.

The `history` and `conversations` tables support incremental sync using their creation timestamps. The `agents`, `voices`, and `models` tables are full refresh only.

## Configuration

| Option | Type | Required |
| --- | --- | --- |
| API key | password | Yes |

## Supported tables

| Table | Description | Sync method | Incremental field | Primary key |
| --- | --- | --- | --- | --- |
| history | Text-to-speech and speech-to-speech generation history. One row per generated audio item. | Incremental, Full refresh | date_unix | — |
| conversations | Conversational AI calls handled by your agents. One row per conversation. | Incremental, Full refresh | start_time_unix_secs | — |
| agents | Conversational AI agent configurations in your workspace. One row per agent. | Full refresh | — | — |
| voices | Voices available in your workspace, including cloned, generated, and premade voices. | Full refresh | — | — |

## Troubleshooting

-   If you see an authentication error, your ElevenLabs API key may be invalid, revoked, or missing a permission for one of the synced endpoints. Check the key's permissions under Profile → API keys in ElevenLabs, then reconnect.

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.
