I'm currently using ledger-autosync (https://github.com/egh/ledger-autosync) to import OFX/QFX files. For some banks it can automatically pull the data using ofxclient (https://github.com/captin411/ofxclient) but for most of my bank accounts this is broken and I need to manually download the OFX file before importing with ledger-autosync. It works OK, I wish I didn't have to do the manual download, but the simplicity of the setup is nice.
I've read of other setups using Plaid or Puppeteer to download their data. Would be interested to hear about what other people are currently using in mid-late 2019 to pull their financial data.
