Have you had many issues with them changing things that break this connectivity? I use Mint and they seem to have endless issues with that despite having obviously close business relationships.
Mint is a financial website/app that hooks into your bank accounts, credit cards, investment accounts, loans, etc. and compiles them all into one place. It also has some built in budgeting tools and such. It's owned by Intuit.
Oh, sorry. Yeah, I've heard about it. I don't like using services like Mint or Personal Capital because they indeed run into connectivity issues sometimes. I find it not to hard to keep track of things using a simple spreadsheet.
So far I've only had to upgrade my script once, when my 401(k) provider changed the ids of some form fields.
