Google Sheets Connector

The Google Sheets Connector is an outbound Connector that allows you to work with an existing or new spreadsheet on Google Drive from your BPMN process.

Prerequisites​

To start working with the Google Sheets Connector, a relevant OAuth token must be configured and stored as a secret in your cluster. The token must have permission to read/write and create a file from a desired Google Drive instance. Follow the steps from the appendix to find out more about creating an OAuth token and assigning relevant permissions.

Create a Google Sheets Connector task​

Currently, the Google Sheets Connector supports next operations:

To use a Google Sheets Connector in your process, either change the type of existing task by clicking on it and using the wrench-shaped Change type context menu icon or create a new Connector task by using the Append Connector context menu. Follow our guide on using Connectors to learn more.

Make your Google Sheets Connector executable​

To make the Google Sheets Connector executable, fill out the mandatory fields highlighted in red in the properties panel.

Appendix & FAQ​

How can I authenticate my Connector?​

The Google Sheets Connector currently supports two methods for authentication and authorization: based on short-lived JWT bearer token, and based on refresh token.

Google supports multiple ways to obtain both. Refer to the official Google OAuth documentation to get up-to-date instructions or refer to the examples below.

You also enable Google Sheets API and Google Drive API for every client intended to use. You can do this from the Google Cloud API Library.

Example 1: Obtaining JWT bearer token with a service account​

danger

The following code snippet is for demonstration purposes only and must not be used for real production systems due to security concerns. For production usage, follow the official Google guidelines.

Assuming you have created a service account and downloaded a JSON file with keys, run the following Python 3 snippet that prints the JWT token in the terminal:

import google.auth
import google.auth.transport.requests
from google.oauth2 import service_account
# Scopes required to execute 'create' endpoind with Google Sheets API
SCOPES = ['https://www.googleapis.com/auth/drive', 'https://www.googleapis.com/auth/drive.file', 'https://www.googleapis.com/auth/drive.appdata']
# File with keys
SERVICE_ACCOUNT_FILE = 'google-service-account-creds.json'
credentials = service_account.Credentials.from_service_account_file(SERVICE_ACCOUNT_FILE, scopes=SCOPES)
auth_req = google.auth.transport.requests.Request()
credentials.refresh(auth_req)
# Print token
print(credentials.token)

Example 2: Obtaining bearer and refresh tokens with OAuth client​

danger

The following code snippet is for demonstration purposes only and must not be used for real production systems due to security concerns. For production usage, follow the official Google guidelines.

Assuming you have created an OAuth client, you can download key files from the Google Console. Run the following Python 3 snippet that prints the refresh token in the terminal:

from google_auth_oauthlib.flow import InstalledAppFlow
import pprint

SCOPES = ['https://www.googleapis.com/auth/drive', 'https://www.googleapis.com/auth/spreadsheets']
OAUTH_KEYS = './oauth-keys.json' # path to your file with OAuth credentials

def main():
    flow = InstalledAppFlow.from_client_secrets_file(OAUTH_KEYS, SCOPES)
    creds = flow.run_local_server(port=54948)
    pprint.pprint(vars(creds))

if __name__ == "__main__":
    main()

Where do I get a spreadsheet ID?​

The spreadsheet ID is located within the URL of the Google Sheets document. Here's how to find it:

For example, if the URL looks like this:

https://docs.google.com/spreadsheets/d/1xhNL0a6WjZtYRHF2522FrCYUYxHve9ju-DHNkaTm9Sk/edit#gid=0

The spreadsheet ID is the alphanumeric string between d/ and /edit, which in this case is 1xhNL0a6WjZtYRHF2522FrCYUYxHve9ju-DHNkaTm9Sk.

Where do I get a worksheet ID?​

The Worksheet ID (also known as the gid) can be found in the same URL. Here's how to find it:

For example, if the URL looks like this:

https://docs.google.com/spreadsheets/d/1xhNL0a6WjZtYRHF2522FrCYUYxHve9ju-DHNkaTm9Sk/edit#gid=0

The worksheet ID is the number after #gid=, which in this case is 0.

What is a worksheet index?​

You can define the place where a new worksheet will be created. By default, the new worksheet will be created at the end of the worksheet. Keep in mind, count starts from 0. For instance, to create a new worksheet on the second place, worksheet index should be set as 1.

What is a row index?​

Row index is the unique identifier for each row in some worksheet, which is used both for reading and writing operations with row. This index is defined to the left of the row.

How can I define which column will be deleted?​

There are two ways to define which column will be deleted: by letter index and numeric one. Numeric index can be found at the top of the column.

The other option is to use numeric index. Keep in mind count starts from 0. To delete column A, numeric index should be 0, B -> 1...
