Below are some scripts that I have created using the Starling Bank API to retrieve my balance, latest transactions, details about my Savings Goals and calculated both daily and instant RoundUps for each transaction.
Balance, last 5 transactions and Savings Goal details - Link - (Details coming soon, just tidying up the code)
Instant RoundUps into a Savings Goal - Link
Instantly Rounds Up the transaction and transfers it into a Starling Bank Savings Goal.
Simply configure your Starling Bank Personal Access Token (with the transaction:read, savings-goal:read and savings-goal-transfer:create scopes), the ID of the Savings Goal you'd like the RoundUp to go into and an email address to send notification to.
