Get Google Business Notifications from push Pub/Sub - google-cloud-platform

Question

I'm trying to be notified when a new review is added on my Google Business Profile.
According to the documentation, I have setup the notification but I got nothing when a new review is added.
First of all, I have created a Pub/Sub Topic projects/my-project/topics/business-profile-notifications.
Then, I have created a Push subscription projects/my-project/subscriptions/business-profile-notifications-push attached to the previous created Topic. I have also defined an endpoint: https://my-endpoint/webhook. This endpoint is listening POST requests
Finally, I have added the service account mybusiness-api-pubsub#system.gserviceaccount.com into IAM with Pub/Sub admin role.
On the code side, I'm using NPM googleapis client in a TypeScript Node.js server.
I'm updating the account settings to setup the notifications:
const { data }: GaxiosResponse<mybusinessnotifications_v1.Schema$NotificationSetting> = await google.mybusinessnotifications({
version: 'v1',
auth,
}).accounts.updateNotificationSetting({
name: `accounts/${params.accountID}/notificationSetting`,
updateMask: 'notification_types',
requestBody: {
name: `accounts/${params.accountID}/notificationSetting`,
pubsubTopic: 'projects/my-project/topics/business-profile-notifications',
notificationTypes: [
'NEW_REVIEW',
'UPDATED_REVIEW',
],
},
});
At this point, nothing happens when a new review is added.
When I'm sending a POST request on my endpoint via curl command curl -X POST -H "Content-Type: application/json" -i "https://my-endpoint/webhook", the request is successfully catched.
In the other hand, when I'm getting notifications settings from the configured account, I have the notifications types but not any subscribed topic:
const { data }: GaxiosResponse<mybusinessnotifications_v1.Schema$NotificationSetting> = await google.mybusinessnotifications({
version: 'v1',
auth,
}).accounts.getNotificationSetting({
name: `accounts/${accountID}/notificationSetting`,
fields: 'pubsubTopic,notificationTypes',
});
Response:
{
"notificationTypes": [
"NEW_REVIEW",
"UPDATED_REVIEW"
]
}
What I forgot to do ?

Answer 1

I resolved the issue by myself 😁
In the documentation of updateNotificationSetting method, is it stated that "The only editable field is notificationSetting" about the updateMask field. But it's wrong. I had to add pubsubTopic as value.
Finally, the parameter values of this method are:
const opts = {
name: `accounts/${params.accountID}/notificationSetting`,
updateMask: 'notificationTypes,pubsubTopic',
requestBody: {
name: `accounts/${params.accountID}/notificationSetting`,
pubsubTopic: params.pubsubTopic,
notificationTypes: params.notificationTypes,
},
};
const { data }: GaxiosResponse<mybusinessnotifications_v1.Schema$NotificationSetting> = await google.mybusinessnotifications({
version: 'v1',
auth,
}).accounts.updateNotificationSetting(opts);
