Description
Hi there 👋,
First of all, thank you for this Coinbase trading bot project – I really want to use it with small trades like PEPE/USDC.
I'm trying to use the bot in Google Colab (Python 3) and I followed the README and set up the API with:
- API Key ✅
- API Secret ✅
- API Passphrase ✅
I only activated "View" and "Trade" and selected my Default Portfolio.
❗️ Problem:
When I run the bot, I get this error: API Response Status Code: 401
API Response Text: Unauthorized
⚠️ Fehler: 401 Client Error: Unauthorized for url: https://api.coinbase.com/api/v3/brokerage/products/PEPE-USDC
