Import Quaderno Data to Google Sheets

In this guide, we’ll walk through how to pull data from the Quaderno API directly into Google Sheets, using the API Connector add-on for Sheets.

We'll first get an API key from Quaderno, and then set up a request to pull in invoice data to your spreadsheet.

Before You Begin

Click here to install the API Connector add-on from the Google Marketplace.

Part 1: Get Your Quaderno API Key

1. While logged into your Quaderno account, click your Profile icon and then API keys from the header bar.
   
2. Copy down your Private Key. That is the only value we need here.
   
3. One last step. Quaderno uses Basic Authentication, so you need to encode your API key. To encode your credentials, type your API key into this form, using the format {Private key}:x (your private API key, then a colon, and then the letter x). Your encoded credentials will appear underneath.
   
   The encoding script runs in your browser, and none of your credentials are seen or stored by this site.
   Base64 Encode

    

Part 2: Create Your Quaderno API Request URL

We’ll first get a list of invoices.

• API root: https://YOURSITE.quadernoapp.com/api
• Endpoint: /invoices.json

Putting it together, we get the full API Request URL:

 https://YOURSITE.quadernoapp.com/api/invoices.json

Just enter in your own subdomain.

Part 3: Pull Quaderno API Data into Sheets

We can now enter that URL into API Connector.

1. Open up Google Sheets and click Extensions > API Connector > Open.
2. In the Create screen, enter the Request URL we just created
   
3. We don't need OAuth, so leave that set to None.
4. Under Headers, enter Authorization as your Key, and Basic {base64-encoded string} as the value:
   

   Authorization

   Basic BASE64_ENCODED_STRING

   Replace BASE64_ENCODED_STRING with the base64-encoded string you created in part 1.
   

5. Create a new tab and click Set current to use that tab as your data destination.
6. Name your request and click Run. A moment later you’ll see a list of your Quaderno invoices in your Google Sheet:

Part 4: More Example API URLs

You can check the documentation for the full list of available API requests,  but if you just want to jump in, you can play around with the URLs you enter in the API URL path field. Try the following (one at a time):
https://YOURSITE.quadernoapp.com/api/contacts.json
https://YOURSITE.quadernoapp.com/api/receipts.json
https://YOURSITE.quadernoapp.com/api/credits.json
https://YOURSITE.quadernoapp.com/api/expenses.json
https://YOURSITE.quadernoapp.com/api/expenses.json
https://YOURSITE.quadernoapp.com/api/estimates.json
https://YOURSITE.quadernoapp.com/api/recurring.json
https://YOURSITE.quadernoapp.com/api/items.json
https://YOURSITE.quadernoapp.com/api/payments.json

Part 5: Handle Pagination

Quaderno limits the number of records returned in each request. By default, only 25 records will be returned unless you use the 'limit' and 'page' parameters as described in their documentation.

With API Connector, you can run these URLs manually or loop through them automatically with pagination (paid feature), like this:

• Pagination: page parameter
• Page parameter: page
• Run until: choose when to stop fetching data
