Create a Coinbase API Key

This tutorial guides you to create a read-only Coinbase API key (Advanced Trade) to automatically sync your transactions.

Set permissions

Download the PEM file
After creation, Coinbase generates a .pem file containing your private key. Download it and open it with a text editor.
