If you plan to run the sample, you will need to temporarily upgrade to a Firebase plan that allows for outbound networking, such as the [Blaze Plan](https://firebase.google.com/pricing/), also called Pay as you go. 12 | 13 | ## Setup Instructions 14 | ### Prerequisites 15 | 1. Node.js and NPM 16 | + We recommend installing using [NVM](https://github.com/creationix/nvm) 17 | 1. Install the [Firebase CLI](https://developers.google.com/assistant/actions/dialogflow/deploy-fulfillment) 18 | + We recommend using version 6.5.0, `npm install -g firebase-tools@6.5.0` 19 | + Run `firebase login` with your Google account 20 | 21 | ### Configuration 22 | #### Actions Console 23 | 1. From the [Actions on Google Console](https://console.actions.google.com/), New project (this will become your *Project ID*) > **Create project** > under **More options** > **Conversational** 24 | 1. From the top menu under **Develop** > **Actions** (left nav) > **Add your first action** > **BUILD** (this will bring you to the Dialogflow console) > Select language and time zone > **CREATE**. 25 | 1. In the Dialogflow console, go to **Settings** ⚙ > **Export and Import** > **Restore from zip** using the `agent.zip` in this sample's directory. 26 | 27 | #### Cloud Platform Console 28 | 1. From the [Dialogflow console](https://console.dialogflow.com) > go to **Settings** ⚙ and under the `General` tab > go the `Project Id` link, which will take you to the **Google Cloud Platform** console 29 | 1. In the Cloud console, go to **Menu ☰** > **APIs & Services** > **Library** 30 | 1. Select select **Maps Static API** > **Enable** 31 | 1. Under **Menu ☰** > **APIs & Services** > **Credentials** > **Create Credentials** > **API Key** and copy the key. 32 | 33 | #### Firebase Deployment 34 | 1. On your local machine, in the `functions` directory, run `npm install` 35 | 1. Run `firebase deploy --project {PROJECT_ID}`, replace `{PROJECT_ID}` to deploy the function 36 | 1. Run `firebase functions:config:set maps.key={API_KEY} --project {PROJECT_ID}`, replace `{API_KEY}` with the generated API key from earlier and redeploy the function. 37 | + To find your **Project ID**: In [Dialogflow console](https://console.dialogflow.com/) under **Settings** ⚙ > **General** tab > **Project ID**. 38 | 1. Return to the [Dialogflow Console](https://console.dialogflow.com) > select **Fulfillment** > **Enable** Webhook > Set **URL** to the **Function URL** that was returned after the deploy command > **SAVE**. 39 | ``` 40 | Function URL (dialogflowFirebaseFulfillment): https://${REGION}-${PROJECT_ID}.cloudfunctions.net/dialogflowFirebaseFulfillment 41 | ``` 42 | 1. From the left navigation menu, select **Integrations** > **Integration Settings** under Google Assistant > Enable **Auto-preview changes** > **Test** to open the Actions on Google simulator then say or type `Talk to my test app`. 43 | 44 | ### Running this Sample 45 | + You can test your Action on any Google Assistant-enabled device on which the Assistant is signed into the same account used to create this project. Just say or type, “OK Google, talk to my test app”. 46 | + You can also use the Actions on Google Console simulator to test most features and preview on-device behavior. 47 | 48 | ## References & Issues 49 | + Questions?
