Cannot Link Existing Project to Google Play Console API

Question

When I click on link existing project under API access on the Google Play Console, my existing cloud project does not show up.

Answer 1

Since I am the owner of my Google Play Console account, the only thing that was missing for me - to enable the Google Play Developer API for the existing project:

1) Type the "Google Play Developer API" in the search box on the project's home screen.

2) Then Click on the "Google Play Android Developer API" search result:

3) Click "Enable"

4) (!!!) Refresh the Google Play Console page with API settings
