# Actions on Google: Digital Goods Sample

This sample demonstrates Actions on Google features for use on Google Assistant including the Digital Purchase API -- using the [Node.js client library](https://github.com/actions-on-google/actions-on-google-nodejs) and deployed on [Cloud Functions for Firebase](https://firebase.google.com/docs/functions/).

    + Must do an Alpha release at minimum
+ You can only test digital goods on Android devices.
    + Google Assistant installed alongside a payment method set up for your Google account.
    + **Note**: All purchases are done in Sandbox mode by default.
+ Brand verification must be completed before testing (website and Android app state `Connected` in Actions console).

Once you've verified your site it will take up to 24hrs for *Brand verification* reflect this change in the Actions console, nonetheless move on to the next step.
1. Back in the Actions console, from the top menu under **Develop** > **Actions** > **Add your first action** > **BUILD** (this will bring you to the Dialogflow console) > Select language and time zone > **CREATE**.
