Linking Metabase as a source

The Metabase connector pulls your Metabase data into the PostHog Data warehouse, so you can analyze your Metabase content and metadata alongside your product data.

Prerequisites

You need a Metabase instance and credentials with read access to the data you want to sync. To use an API key, your instance must be Metabase v0.47 or newer; older instances can authenticate with a username and password instead.

Adding a data source

1. In PostHog, go to the Sources tab of the data pipeline section.
2. Click + New source and click Link next to this source.
3. Enter your credentials (see 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 Metabase, you'll need:

• Instance URL – your Metabase instance's public URL, for example https://your-company.metabaseapp.com.
• Authentication method – choose one of the following:
  • API key – create one in Metabase under Admin settings > Authentication > API keys (Metabase v0.47+). The key needs read access to the data you want to sync.
  • Username & password – the email and password of a Metabase user with read access to the data you want to sync.

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 for a full explanation of how each mode works and how to choose between them.

This source is full refresh only.

Configuration

Supported tables

The tables available from this source are discovered from your account when you connect it, so the exact list depends on your data. Once connected, you can pick which tables to sync from the sources tab.

Troubleshooting

• If you see an authentication error, your credentials may be invalid or expired. Update them and reconnect.
• If you see a permissions error, grant the API key or user read access to the data you want to sync, then reconnect.
• If the host is rejected, use your instance's public URL.

If your sync is failing or data looks wrong, see the Data warehouse troubleshooting guide. If that doesn't help, contact support – we're happy to help.
