nook-number's Introduction

Nook Number

Sometimes I spend a little bit more each month than I'm supposed to.

This function texts me every day with the balance on my main credit card. That's it.

Design

The code & its dependencies live in AWS Lambda, and is scheduled through Amazon Eventbridge.

I use the Plaid API to get my account information. It's free since I linked <5 accounts, and Nook Number is only for personal use. Twilio's free tier (Programmable SMS) is used for sending the text message.
