How to get Google Play Subscription notifications in cloud functions

Question

I am trying to get the response of the req.body of my notifications from Google Play Services in firebase cloud functions.

The notifications come through a webhook on subscription or cancellation. Everything seems to be reporting fine. I am getting something wrong with the response data? Because trying to get some field values logs undefined:

console.log(req.body.kind) // logs undefined
console.log(req.body.autoRenewing) // logs undefined

Below is supposed to be the req.body:

{
  "kind": string,
  "startTimeMillis": string,
  "expiryTimeMillis": string,
  "autoResumeTimeMillis": string,
  "autoRenewing": boolean,
  "priceCurrencyCode": string,
  "priceAmountMicros": string,
  "introductoryPriceInfo": {
    object (IntroductoryPriceInfo)
  },
  "countryCode": string,
  "developerPayload": string,
  "paymentState": integer,
  "cancelReason": integer,
  "userCancellationTimeMillis": string,
  "cancelSurveyResult": {
    object (SubscriptionCancelSurveyResult)
  },
  "orderId": string,
  "linkedPurchaseToken": string,
  "purchaseType": integer,
  "priceChange": {
    object (SubscriptionPriceChange)
  },
  "profileName": string,
  "emailAddress": string,
  "givenName": string,
  "familyName": string,
  "profileId": string,
  "acknowledgementState": integer,
  "externalAccountId": string,
  "promotionType": integer,
  "promotionCode": string,
  "obfuscatedExternalAccountId": string,
  "obfuscatedExternalProfileId": string
}

My webhook

export const googlePlayWebhook = functions.https.onRequest((req, res) => {

    const data = req.body;
    console.log('start response body google');
    console.log(data.autoRenewing);
..

What am I missing?

Answer 1

It should be const data = req.data; instead of const data = req.body;
