1. Go to the Toggl API documentation to understand how to interact with the Toggl API.
2. Register for a Toggl account if you haven’t already, and get your API token from the bottom of the Toggl Profile Settings page.

1. Go to the Google Developers Console.
2. Create a new project or select an existing one.
3. Navigate to the “Library” section and enable the Google Sheets API for your project.
4. Go to “Credentials” and create credentials for your application. You’ll need an OAuth 2.0 client ID for a web application.
5. Download the JSON file that contains your client ID and client secret.

1. Go to Google Sheets and create a new spreadsheet.
2. Name the spreadsheet and take note of the spreadsheet ID found in the URL (between /d/ and /edit).

1. Choose a programming language that you’re comfortable with. For this example, we’ll use Python.
2. Install the necessary libraries for HTTP requests and OAuth2 (e.g., requests for Python).
3. Write a script that uses your Toggl API token to authenticate and fetch data from Toggl. You’ll likely be making a GET request to an endpoint like https://api.track.toggl.com/reports/api/v2/details to get detailed report data.
4. Parse the response data into a format suitable for insertion into Google Sheets (e.g., a list of lists, where each inner list represents a row).

1. Using the Google Sheets API or Apps Script, authenticate with the OAuth 2.0 credentials you downloaded.
2. Write a function that takes the parsed data from Step 4 and inserts it into the Google Sheet you created. You may use the spreadsheets.values.append method to append data to the sheet.

1. Combine the Toggl data fetching and Google Sheets data insertion scripts into a single script or process.
2. Ensure that you handle pagination if the Toggl data exceeds one page.
3. Run the script and check your Google Sheet to see if the data has been inserted correctly.

1. If you want to automate the process, you can schedule the script to run at regular intervals.
2. This could be done using a cron job on a Linux server, Windows Task Scheduler, or any other scheduling tool that works with your setup.

Sample Python Code

Here’s a very basic example of how you might start writing a Python script to fetch data from Toggl and insert it into Google Sheets:

import requests
from google.oauth2.credentials import Credentials
from googleapiclient.discovery import build

# Toggl API request
toggl_api_token = 'YOUR_TOGGL_API_TOKEN'
auth_header = {'Authorization': 'Basic ' + toggl_api_token}
toggl_url = 'https://api.track.toggl.com/reports/api/v2/details'
toggl_params = {
   'workspace_id': 'YOUR_WORKSPACE_ID',
   'since': 'START_DATE',
   'until': 'END_DATE'
}
toggl_response = requests.get(toggl_url, headers=auth_header, params=toggl_params)
toggl_data = toggl_response.json()

# Parse Toggl data
toggl_rows = []
for entry in toggl_data['data']:
   toggl_rows.append([
       entry['description'],
       entry['start'],
       entry['end'],
       entry['duration']
   ])

# Google Sheets API request
spreadsheet_id = 'YOUR_SPREADSHEET_ID'
range_name = 'A1'
creds = Credentials.from_authorized_user_file('path_to_your_credentials.json')
service = build('sheets', 'v4', credentials=creds)
sheet = service.spreadsheets()

# Insert data into Google Sheets
request = sheet.values().append(spreadsheetId=spreadsheet_id, range=range_name,
                               valueInputOption='USER_ENTERED', body={'values': toggl_rows})
response = request.execute()


Please ensure you replace placeholders like 'YOUR_TOGGL_API_TOKEN', 'YOUR_WORKSPACE_ID', 'START_DATE', 'END_DATE', 'YOUR_SPREADSHEET_ID', and 'path_to_your_credentials.json' with your actual data.
