i want to write a desktop CoinBase Client and i have problems with signing in. At first i am confused becasue it seems that there is v2 (https://api.coinbase.com/v2) and v3 (https://api.coinbase.com/api/v3/). Is v2 old and v3 new and should i only use v3?
Next is that there are two places of creating an API-Key. In the documentation (Sign In With Coinbase API Key Authentication | Coinbase Cloud) there is always referenced that site: https://www.coinbase.com/settings/api
Is that right or is that a mistake?
I read that there are also two sign in methods, API-Key and OAuth. On the referenced site i can not create an API-Key, because there comes an error. And if i try to create an OAuth i am not able to get the client_secret that i need for the handshake…
I can later post some code, but at first i need some answeres to my questions to get al this in order.
Thanks a lot.
