Import Kraken Data to Google Sheets
In this guide, we’ll walk through how to pull public market and cryptocurrency data from the Kraken API directly into Google Sheets, using the API Connector add-on for Sheets. Kraken is an trading exchange for Bitcoin and other cryptocurrency.
The output for Kraken isn’t very well structured for a tabular format like Sheets, and their naming conventions are (in my opinion) unnecessarily cryptic, so you will need to restructure the data after you pull it into Sheets. But with that said, it can still be a nice alternative to more popular crypto APIs like CoinGecko, since it is more reliable and provides a lot of detailed data points.

Before You Begin

Part 1: Fetch Data from Kraken
The easiest way to get started with the Kraken API is through API Connector’s built-in integration.
- Select Kraken from the drop-down list of applications
- Select an endpoint. These endpoints are all open so you don’t need an API key. For this example we’ll choose the
/public/Tickerendpoint, which provides ticker information for an asset pair.
- Under Request parameters, choose an asset pair for the
- Choose a destination sheet, name your request, and hit Run.
- The output here is pretty confusing, so we need to refer to the documentation to know what it means:
- Basically, the output contains the currency pair you selected, and then letters representing the fields you see above (a = ask array, b = bid array, c = last trade closed aray, v = volume array, and so on).
- Since these field names use individual letters instead of names, we need to rename those fields to make it meaningful. To rename your fields, open the visual field editor by clicking Edit Fields, then click the blue pencil in each header and enter a new name for each column (for example: ask_price, ask_whole_lot_volume, ask_lot_volume,bid_price, bid_whole_lot_volume, ask_lot_volume, last_trade_price, last_trade_lot_volume, volume_today, volume_last_24h, volume_weighted_avg_price_today, volume_weighted_avg_price_24h, numer_trades_today, number_trades_last_24h, low_today, low_last_24h, high_today, high_last_24h, today_opening_price)
- After saving your field names, you won’t need to update them again, they’ll stay in place for all future data refreshes.
Part 2: Create a Custom Request
Alternatively, you can run your own custom requests instead of using API Connector’s pre-built integration. When you create a custom request, you add your complete URL into the Request URL field.
Part 3: More Example API URLs
Here are some more examples of custom API URLs. Check the documentation for the full set of available requests.
