Ask HN: How do Swipely and Blippy get their data?

[gilaniali]

I couldn't find this online, but was wondering how they were going about pulling people's purchases?

I doubt all or any banks have apis. Are they then simply scraping data by using the customers log-in info?

Probably the similar to how Mint and inDinero works; they use a third party service (such as Yodlee) which provide aggregation of financial data.
