At the moment, I am authenticating as my linked android apps google service account to verify and try to acknowledge android in app Subscriptions. I can verify them using the GET call, but when i make the POST and append :acknowledge to the end of the URL, i receive the following error
{
"error": {
"code": 400,
"message": "The product purchase is not owned by the user.",
"errors": [
{
"message": "The product purchase is not owned by the user.",
"domain": "androidpublisher",
"reason": "productNotOwnedByUser"
}
]
}
}
The service account has been granted all permissions as far as i can tell via the android app store
when i make a GET call without :acknowledge I receive responses like this and can see that the subscription still has not been acknowledged.

When using the google-play-billing-validator node package, only twice have I seen a successful acknowledged purchase. It happened the first time i tried, then after cancelling a subscription during testing, and retrying, i am unable to acknowledge it again. then they continuously cancel.
exports.googlePlayBillingValidator = functions.https.onRequest((request, response) => {
// capture the data from the request
const { purchaseObject, subscriptionID, type } = request.body;
console.log(subscriptionID, type);
// inclue your app bundle id
const bundleID = "edu.fit.my.jgibb2018.pob";
// require the service account info
const googleServiceAccountKey = require("./pc-api-6835501382478242417-177-5781829bedc5.json"); // see docs on how to generate a service account
// require the verify module
const Verifier = require("google-play-billing-validator");
// create verifier opitons object
const options = {
"email": googleServiceAccountKey.client_email,
"key": googleServiceAccountKey.private_key,
};
// create a new verifier instance
const verifier = new Verifier(options);
// create a receipt object
const receipt = {
packageName: bundleID,
productId: purchaseObject.productId,
purchaseToken: purchaseObject.purchaseToken,
};
if (type.contains("subscriptionAcknowledge")) {
// add the following string to the receipt object `developerPayload: "some unique identifier",`
receipt.developerPayload = "some unique identifier";
}
// acknowledge the receipt
const promiseData = verifier.verifySub(receipt);
promiseData.then(function (r) {
response.send(r);
})
.catch(function (error) {
functions.logger.error(error);
response.send(error);
});
});
