Linking Finnworlds as a source
This source is currently in alpha. The interface and available tables may change.
The Finnworlds connector pulls financial market data into the PostHog Data warehouse, so you can analyze fundamentals, prices, dividends, ratings, and more alongside your product data.
Prerequisites
You need a Finnworlds account with API access so you can obtain an API key.
Adding a data source
- In PostHog, go to the Sources tab of the data pipeline section.
- Click + New source and click Link next to this source.
- Enter your credentials (see Configuration below) and click Next.
- 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 Finnworlds, you'll need:
- API key – find it in your Finnworlds dashboard.
- Tickers – the stock tickers you want to sync (e.g.
AAPL, MSFT, GOOGL). Most datasets (fundamentals, prices, dividends, ratings) return data for one company per request, so the connector fetches each dataset for every ticker. Bond yields are global and ignore the ticker list.
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_attimestamp). 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.
All Finnworlds tables are full refresh only, since the API exposes no incremental sync filter.
