You can use my other tool as an automated way to login to the ONE Finance website and save your user session. This might be helpful if you have problems with this app refreshing your token or don't understand how to copy the user session. However, the next option is my preferred option for using this tool

Copy from ONE website

1. Login to the ONE website at https://web.one.app/
2. Open the developers tools
3. Go to "Application" > Expand "Session Storage" > Click "https://web.one.app"
   
   
   
   
4. Copy the value from the one_user_session key
5. Create a folder/file in this repo called db/one-user-session.json
6. Paste the value you copied from the webiste into this file and save it

Using this tool

Run npm start to initialize the app and download a full history of your transactions and balance history.

State will be stored in the db folder that you created in the previous steps to keep track of which transactions have already been downloaded and which balance history dates have already been exported. This makes subsequent calls with this program quicker and more useful

The csv file output will be stored in a folder called output. You can copy this into your existing programs that you use to track your finances.

The program is built to refresh your user token, so even though the tokens expire every 24 hours, the program will refresh the access token before continuing to pull transactions and balance history
