Notes on TAN handling #43

Open barredterra opened 3 years ago

barredterra commented 3 years ago

TAN handling is not implemented yet. Here are some notes how it could be built.

  1. When a TAN is required, the state of the FinTS3PinTanClient needs to be stored on the server / database (for example, in the FinTS Login doctype).
  2. We send a note to the frontend saying that a TAN is required (frappe.publish_realtime('tan_response_needed'))
  3. The frontend asks the user for the TAN (frappe.prompt()).
  4. The frontend sends the TAN to a whitelisted method in the backend.
  5. The backend method restores the previous state and sends the TAN to the bank.
