I haven't paid the "one-time developer registration fee" and I have uploaded my extension. In my developer dashboard it says.
"The fee is not required to publish only to users in mydomain.com"
How can I publish to users only in mydomain.com without paying the "one-time developer registration fee". I can't find that option anywhere.
To be able to publish to only people in your domain, you must have this permission enabled by the Google Apps for Work administrator for your organization.
From Google: "Administrators can choose which users they want to be able to publish private apps for their organization by clicking this checkbox in the Admin console under Device management > Chrome management > User settings > Chrome Web Store Permissions."
Once this permission has been enabled, you can upload the ZIP file, for your extension, fill out the form, and at the end, select Private (Everyone at yourdomain.com) under Visibility options. This will allow you to publish without paying the fee.
