You do not need to โlinkโ your products in the web store with the Google Developers Console, you just need to pull your project from the Developer Console into the web store and include your application identifier. Quote from the site https://developer.chrome.com/webstore/using_webstore_api :
Download a package to update an existing storage item:
Endpoint: https://www.googleapis.com/upload/chromewebstore/v1.1/items/$APP_ID Type: PUT Header Parameters: $TOKEN: the access token Body content: the package file to upload
$ APP_ID is the identifier of an existing web store item.
> curl \ -H "Authorization: Bearer $TOKEN" \ -H "x-goog-api-version: 2" \ -X PUT \ -T $FILE_NAME \ -v \ https://www.googleapis.com/upload/chromewebstore/v1.1/items/$APP_ID
Example:
First you need to create a new project or import an existing one in the Developer Console, I linked my project with GitHub so that the Developer Console always synchronizes with this repository. You can do this on the Source Code tab in the developers console.
Make sure that the owner of the developer account is the same Gmail account as your Web Store account to simplify the task. Also check if the Chrome Web Store API is 'ON' on the API tab under "API and auth". Under the credentials, you must get your client ID and secret in order to get the code to access the access token. All of this is very well explained in the transition from Google.
Try installing curl ( http://curl.haxx.se/ ), this will help you with POST and GET on the command line. (Examples are also in the walkthrough)
