You'll need an app access key and app secret to authenticate. ## 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 100ms, you'll need: - **App access key** – find it in the **Developer** section of your [100ms dashboard](https://dashboard.100ms.live/). - **App secret** – find it in the same **Developer** section, alongside the app access key. ## Sync behavior Only **completed sessions** are imported. Active (in-progress) sessions are excluded until they finish. The sessions table uses a 24-hour lookback window for incremental sync. This re-reads recent sessions to catch calls that were still in progress when the previous sync ran. Older corrections require a full refresh. Recordings and live streams use full refresh only, since the 100ms API doesn't provide time-bound filters for these endpoints. ## 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. ## Configuration | Option | Type | Required | | --- | --- | --- | | `App access key` | password | Yes | | `App secret` | password | Yes | ## Supported tables | Table | Description | Sync method | Incremental field | Primary key | | --- | --- | --- | --- | --- | | `sessions` | Completed calls in 100ms rooms, with the peers who joined each call. | Incremental, Full refresh | created\_at | — | | `recordings` | Recording jobs for the workspace.

If your sync is failing or data looks wrong, see the [Data warehouse troubleshooting guide](https://posthog.com/docs/data-warehouse/troubleshooting.md).
