Hi Guilherme!
Yes, you'll have to use promises.
To do an HTTP POST you can use a service like *$http*.
Like it's said in the docs, the functions that generate the HTTP request
return an HTTP promise, you should use that promise and assign it some
callbacks that verify the response.
Here's an example:
CheckoutService.canBuy()
.success(function (data) {
// Check if user can buy a thing or not.
})
.error(function (data) {
console.alert('Error');
});
Hope this helps you.
Regards,
*Luís Loureiro*
