Coinbase Pro fills statement export does not work as of Feb 2024 (just in time for tax prep!). Infinite wheel on the front-end, 500 status response from the API. Old Pro API still works and allows exporting fills to compute taxable transactions.

coinbase_pro_fills.py

## Problem

## As a workaround, use old API (as of 2024-02)
## https://github.com/danpaquin/coinbasepro-python
## (Python 3.7) pip install cbpro
import json
import cbpro

# supply API credentials
auth_client = cbpro.AuthenticatedClient(key, secret, passphrase)

# modify product_id as needed
fills_gen = auth_client.get_fills(product_id="BTC-USD")
all_fills = list(fills_gen)
with open("fills.json", 'w') as outfile:
    json.dump(all_fills, outfile)
## use fills.json to compute taxable transactions etc. Import into pandas if easier.
