This is a rudimentary API for NatWest Online banking, based loosely on the Ruby script by @runpaint.

At the moment it consists of a command-line application that simply dumps out your last year of account transactions.

• Install dependencies via NPM
• Create an account.json based on the example provided. Warning: should be chmod 600.
• Run natwest.js

The login procedure for nwolb is pure security theatre. It requires:

• Spoofing your user agent, using Chrome in this case.
• Entering your customer number, then clicking "Log in".
• Determining three specific digits of your PIN, then entering them in individual form fields.
• Determining three specific characters of your password, then entering them in individual form fields.
• Hitting "Next".

(For extra difficulty, the last "Next" button is positioned under a series of three images: if you click on it before the images have loaded, you're likely to click one of those instead, which loads an unrelated page).

Retrieving statements requires the following:

• Traversing to the statements search.
• Adjusting the date fields (to no more than a 365 day range).
• Punching it.
• Clicking the "All" link in the pagination to retrieve all results.
• Parsing the table output.

This utility relies on screen-scraping multiple pages of horrendous HTML. Further, it has only been tested with one account. Feel free to report errors, preferably with the HTML, appropriately sanitised, on which it fails.
