You're seeing this error because your API key doesn't have permission to trade with your selected quote currency based on your country or region.
What's happening:
Coinbase has restricted certain quote currencies from being traded via API keys based on your country or region, even though you may still be able to trade them directly on the Coinbase platform. This is a limitation set by Coinbase, not by Cryptohopper.
Common example:
If you're in Canada and using USDT as your quote currency, Coinbase may block API trading with USDT while still allowing manual trading on their platform.
Example of the error:
How to fix this?
You can fix this by changing your quote currency. For example, switch to USDC, EUR or USD.
