Tip

The names you enter here don't really matter. It's an app that only you will have access to. This will take approximately 10 minutes and Google likes to change these screens often. Sorry.

1. Visit https://console.developers.google.com/apis/credentials

2. Create a project:

   

3. Enter chrome-webstore-upload and Create

4. Visit https://console.cloud.google.com/apis/credentials/consent

5. Select on External and Create

   

6. Only enter the Application name (e.g. chrome-webstore-upload) and required email fields, and click Save

   

7. On the 3rd screen, add your own email address:

   

8. Visit https://console.developers.google.com/apis/library/chromewebstore.googleapis.com

9. Click Enable

10. Visit https://console.developers.google.com/apis/credentials

11. Click Create credentials > OAuth client ID:

    

12. Select Desktop app, enter Chrome Webstore Upload and click Create

    

13. Save your ✅ clientId and ✅ clientSecret:

    

14. Visit https://console.cloud.google.com/apis/credentials/consent

15. Click PUBLISH APP and confirm

    

16. Run this CLI tool to generate the required refreshToken

    npx chrome-webstore-upload-keys

    or

    bunx chrome-webstore-upload-keys

    

17. Done. Now you should have ✅ clientId, ✅ clientSecret and ✅ refreshToken. You can use these for all your extensions, but don't share them!

What the CLI tool does

1. Requests the two keys you have
2. Opens a local server to handle the OAuth redirect from Google's servers with an approvalCode
3. Uses Google's oauth2 API to request a refreshToken
