Indeed! Plaid is integrated with ~every bank that has an API, and in many cases we've actually helped the banks build API's themselves.
It’s something I hit often and have to do the old microdeposit thing (if I can even figure out how to trick the service into allowing me to do that at all).
Does fidelity just have some sort of broken setup?
> To maintain system stability, Fidelity currently limits access during high-volume windows. As a result, please expect unavailability between 9-10:30am and 3-4:30pm ET. We recommend end users link Fidelity accounts between 5pm - 9am ET.
