Sorry if this is the wrong place to ask about this. Generally speaking, is there a way to access one's transaction history via an API? I've created an app that allows me to visualize my spending in bar graphs, etc., similar to how Mint works except I can customize my own categories which helps me get a better visual of how I'm spending my money. Anyhow, is there anything like this out there? Or would this type of thing have to be implemented by each of the credit card issuers for each of my credit cards? Any help or advice is appreciated, obviously companies like Mint and a few others are already doing this so it seems like it should be possible.
