FIO MULTI–ACCOUNT IMPORTER — FULLY COMMENTED VERSION
|
||||
====================================================
|
||||
|
||||
This script downloads transactions for **multiple Fio bank accounts**
|
||||
(using their API tokens) and imports them into a MySQL database
|
||||
(`fio.transactions` table).
|
||||
|
||||
It also saves the raw JSON responses into a folder structure
|
||||
for backup / debugging / later use.
|
||||
|
||||
Main features:
|
||||
• Reads all accounts from accounts.json
|
||||
• Downloads last N days (default 90)
|
||||
• Saves JSON files to disk
|
||||
• Extracts all transactions with safe parsing
|
||||
• Inserts into MySQL with ON DUPLICATE KEY UPDATE
|
||||
• Efficient batch insertion (executemany)
