How to share Google API key access with your client

As a developer, I often create a Google API key for a map, or a calendar, or other Google service. Later, someone else needs to manage the Google API key, such as the client, or their web team, or a third-party marketing service.

How can I give someone access to the Google API key?

Turns out you can add new roles, Editor or Owner, to your Google Services projects. I was really happy to know this.

Below are the steps.

Step 1. Log into Google APIs console: https://console.developers.google.com

Step 2. Go to your project settings.

1. Click your project in the top bar (dropdown).
2. Click to select the project you want in the pop-up window.
3. Click the (obscure) folder settings icon.

Step 3. Add new member.

1. Again, select desired project. (not sure why this is repeated.)
2. Click “Add member” button in slide-in screen on the right.

Step 4. Add new member details.

1. Type in the email address for the new member. This must be a Google account (gmail or a G Suite business email). I think you can tell because a pop-up suggestion occurred for me for a G Suite email, and did not for a non-G Suite email.
2. Select a role, such as “Project -> Owner”.
3. Check notification email.
4. Save.

You should now see a new Owner or Editor (see screenshot under Step 3 above).
