Digital Goods API Plugin for Actions on Google Client Library Node.js

This plugin makes it easier to use Digital Goods API by extending the functionality of the official Actions on Google client library for Node.js. Particularly, it makes it simple to check for available SKUs and consume them if needed.

Currently, plugin supports only Actions built with Dialogflow.

Setup Instructions

Install the library with either npm install actions-on-google-digital-goods-plugin-nodejs or yarn add actions-on-google-digital-goods-plugin-nodejs if you use yarn.

Usage

const { digitalGoodsHelper } = require('actions-on-google-digital-goods-plugin-nodejs')
// user-defined configurations (here only for demonstration purposes)
const { packageName, pathToServiceAccount } = require('./config')
const app = dialogflow({ debug: true }).use(digitalGoodsHelper({
  packageName: packageName,
  auth: require(pathToServiceAccount),
  keepInConv: true,
  consumableIds: ['gas'],
  skus: {
    SKU_TYPE_IN_APP: ['premium', 'gas'],
    SKU_TYPE_SUBSCRIPTION: ['gold_monthly', 'gold_yearly']
  }
}))
 
app.intent('asking for a purchase', async conv => {
  // skus will be a map of Sku objects indexed by its sku id.
  // they are also get stored as conv.data.skus if keepInConv flag has
  // been set to true during plugin initialization.
  const skus = await conv.digitalGoods.getSkus()
  conv.ask(`Would you like to buy any of: ${Object.keys(skus)}?`)
})
 
app.intent('initiate the purchase', async (conv, { sku }) => {
  conv.ask('Great! Here you go.');
  conv.digitalGoods.purchaseSku(sku);
});
 
app.intent('describe purchase status', async conv => {
  const status = conv.arguments.get('COMPLETE_PURCHASE_VALUE');
  if (status === 'PURCHASE_STATUS_OK') {
    // If no arguments supplied to canConsume and consume, they will try to
    // look up in conv.data.purchasedItemSkuId, which is automatically set
    // if using conv.purchaseSku method. Otherwise, you will need to supply
    // the sku id yourself.
    if (conv.digitalGoods.canConsumeSku()) {
      await conv.digitalGoods.consumeSku()
    }
  }
  // check other statuses
})
