A simple webservice that implements a Coin Jar for your Starling Bank account.
This service watches your Starling Bank transaction log for the things you spend. For any transaction it sees it rounds up the amount to the nearest pound (£) and puts it in a virtual coin jar savings goal - much like you would do with the change in your pocket at the end of the day.
TLDR. Create Starling Developer account and retrieve personal access tokens. Start up this service at an accessible url/domain with those tokens. Point a new webhook in your Starling Developer account at that same url/domain. It creates a Goal for you and starts working.
