Legacy API keys are not working with Advanced API from 27th

Advanced Trade API

It seems Advanced-API keys are now renamed to Legacy API keys in the documentation and they are not working anymore. I keep getting 403 error for the same keys. See the following logs for the exact timestamp:

Iā€™m also using the legacy key and have experienced issues creating orders. However, it was due to the accounts/currencies not being available. Nothing to do with the auth itself. Try and log the errors from the order process.

Ok, I found the issue. Coinbase has retired their previously working endpoint https://coinbase.com/... in favor of https://api.coinbase.com/....
