GMB MyBusiness API - How to set up real-time PubSub notifications? - google-cloud-platform

Question

I am working on integrating GMB into some of our internal apps, and would like to set up to receive real-time notifications for reviews and questions.
I have created a topic, and a subscription with a valid URL.
The next step is to tell GMB to send the notifications to the topic, and I believe the endpoint is the one below. However, it is very vague about the parameters it wants.
This is the documentation
https://developers.google.com/my-business/reference/rest/v4/accounts/updateNotifications
It wants a "Notification Settings Resource Name" in the URL, but it's not explained anywhere what that actually is. I have tried every possible value, but always get a 404 error response with the message "Requested entity was not found."
Has anyone successfully set this up? What values does the "getNotifications" endpoint want, and where in the various dashboards can this be found or created?
Any help is much appreciated!

Answer 1

As mentioned in the comments, you need to send the accountId as part of the URL.
To find this, you will first need to send a GET request to
https://mybusiness.googleapis.com/v4/accounts
This will return something along the following lines:
{
"accounts": [
{
"name": "accounts/102647145453118950380",
"accountName": "Tom Spencer",
"type": "PERSONAL",
"state": {
"status": "UNVERIFIED",
"vettedStatus": "NOT_VETTED"
},
"profilePhotoUrl": "//lh3.googleusercontent.com/a-/AOh14GgPkuJj03DeCa1isBAJALY4eOl09WGYVFrM4mG5=s132"
},
]
}
You can see here that accounts/102647145453118950380 is returned in the name field. Take this field, and construct the following URL:
https://mybusiness.googleapis.com/v4/accounts/102647145453118950380/notifications
Send a PUT request to this URL, with a request body resembling the following:
{
"topicName": "projects/{projectId}/topics/{topicId}",
"notificationTypes": [
"NEW_REVIEW",
"UPDATED_REVIEW"
]
}
Assuming you have pub/sub setup as per the documentation, this should send a message to your topic/subscribers whenever a new review is created or a review is updated.
