Leaderboard issue

I'm trying to add a leaderboard to my game for which I have used CloudOnce. My concern is regarding the SHA1 certificate fingerprint. When I look at the app singing option under release management, there are two SHA1 fingerprint's. One is listed under "App signing certificate" and the other one under "Upload certificate" and the SHA1 fingerprint's are different.

Now when I go to game services and click on the "API Console project", it takes me to GoogleAPI's. Here when I look at the "OAuth 2.0 Client IDs" under the credentials option, there is one SHA1 fingerprint certificate. This is the same as the one found under "App signing certificate". My question is, for testing purposes, do I need to change this to the SHA1 fingerprint that's under the "Upload certificate" or leave it as it is?
