Google Play Developer API purchases.subscriptions doesn't return emailAddress field

Question

I'm integrating with Google Play Developer API (https://developers.google.com/android-publisher). To be more specific I'm trying to get informations about a specific subscription (https://developers.google.com/android-publisher/api-ref/rest/v3/purchases.subscriptions/get).

Well I'm already getting informations about a subscription with the subscriptionId and purchaseToken. The problem is that some fields are not being returned in response. One of these field is emailAddress that importante for my usage context. I'm getting a response like the one shown below.

{
    "startTimeMillis": "1631112305355",
    "expiryTimeMillis": "1638981894973",
    "autoRenewing": true,
    "priceCurrencyCode": "BRL",
    "priceAmountMicros": "39990000",
    "countryCode": "BR",
    "developerPayload": "",
    "paymentState": 1,
    "orderId": "GPA.9999-5849-9341-89139",
    "acknowledgementState": 1,
    "kind": "androidpublisher#subscriptionPurchase"
}

From the docs about emailAddress we have The email address of the user when the subscription was purchased. Only present for purchases made with 'Subscribe with Google'.

But what is Subscribe with Google? Isn't Google Play Billing in this category? My purchases are made on an Android mobile app with Play Billing.

Thanks any help.

Subscribe with Google is a completely different thing that Google offers or at least used to offer, these are not normal subscriptions, for normal subs you do not get the users email.

Subscribe with Google lets you buy a subscription, using your Google account, on participating news sites. Select the publisher offer you’d like to buy, click “Subscribe,” and you’re done. You’ll automatically be signed in to the site, and you can pay–securely and privately—with any credit card you’ve used with Google in the past.
