GET operation status via API not CMD - google-cloud-vision

Question

In Google Cloud vision API documentation for the product search, the method for getting operation status is listed as CMD but there is no C# code example for it in order to check any long-running operation status.
I tried calling this method in postman but it didn't work as I cannot add the service account credentials
GET https://vision.googleapis.com/v1/locations/location-id/operations/operation-id
Would appreciate any guidance on this.

Answer 1

It turns out there are two solutions:
Using Google Cloud Vision REST APIKEY as a query parameter for (you will have to generate your own API key from the cloud console credentials)
GET https://vision.googleapis.com/v1/locations/location_id/operations/operation_id?key=value
Using AJAX with stringify to append the service account JSON key file with the request which is sent to the same URL above.
checkStatus: function() {
if (this.get('stop') || !this.getOperationUrl()) {
return;
}
$.ajax({
url: '/getOperation',
type: 'POST',
data: JSON.stringify({
operation_url: this.getOperationUrl(),
key: this.config_model.get('key'),
}),
cache: false,
contentType: 'application/json',
dataType: 'json',
}).done(function(response) {
const result = response.response;
if (!response.success || !result) {
console.log(response);
this.set('response', response);
} else {
if (result.done) {
this.set('response', response);
} else {
setTimeout(function() {
this.checkStatus();
}.bind(this), 5 * 1000);
}
}
}.bind(this));
