DBS Statement Downloader

Python library that logs into the DBS iBanking frontend and download estatements using Selenium.

Since logging into the frontend requires an OTP, text-forwarding (independent of this repository) is used to send the contents of the SMS to a Gmail service account. This OTP is then passed to the Selenium browser.

Requests are then made to the undocumented DBS backend API (https://internet-banking.dbs.com.sg/api/v3/channels/estatements) to retrieve the relevant bank statements.

Usage

The downloader can be run directly:

python3 src/dbs/main.py

or with Docker compose:

docker-compose build && docker-compose up

Prerequisites

• Text-forwarding from iPhone/Android to an email account. On iOS, one possible method is to use an automation to forward SMS messages from DBS to an email account.

• Google Cloud account, with the Gmail API enabled (see Google Cloud docs)

• Authorized Gmail account (see Gmail API docs)

• Secret stored on Google Secret Manager, which is defined in the .env file as SECRET_ID. The secret should be the contents of the token.json file generated by running the quickstart.py script in this repository. This allows the OTP to be retrieved from Gmail.

  Note: quickstart.py requires a credentials.json file to generate the Gmail access token, which can be generated with these steps.
