UPDATE to clarify the question...In attempting google drive example app Dr edit for php working in our test app which had already successfully implemented the licensing API, https://developers.google.com/chrome/web-store/docs/samples#php, we got an 'error saving' message and a syntax error from dredit.js trying to log error to console. We realized that we needed to update the existing apps manifest.json with some needed info, setting the CONTAINER to GOOGLE_DRIVE and the id from API console.However, that brought a warning from developer dashboard that made us sad because it seems our task is not possible:\[quote\]
- Apps that specify a container other than CHROME in the manifest may not use Chrome Web Store payments.
