Small library to help with the Alexa ProactiveEvents API
You have to onboard your skill with the proactive events API
This is a specific process and so the best documentation is the Amazon docs on the subject
With the client ID and secret from your Amazon developer console
var messaging = new AccessTokenClient(AccessTokenClient.ApiDomainBaseAddress);
var details = await messaging.Send("clientId","clientSecret");
var token = details.Token;There are several event types, each in their own namespace, the simplest example is one of a Weather Alert
using Alexa.NET.ProactiveEvents.WeatherAlerts;
...
var eventToSend = new WeatherAlert(WeatherAlertType.Snowstorm);Some alerts have required fields which must be created with a string per locale for each you support. These are created as LocaleAttributes.
var localeAttribute = new LocaleAttributes();
localeAttribute.Add("en-GB","GBLocale");
localeAttribute.Add("en-US","USLocale");or if you're only in one locale
var localeAttribute = new LocaleAttributes("en-GB","GBLocale");
var eventToSend = new WeatherAlert(WeatherAlertType.Tornado,localeAttribute);var request = new Alexa.NET.ProactiveEvents.UserEventRequest("userId",eventToSend)
{
ExpiryTime = DateTimeOffset.Now.AddMinutes(10),
ReferenceId = Guid.NewGuid().ToString("N"),
TimeStamp = DateTimeOffset.Now,
};var request = new BroadcastEventRequest(eventToSend)
{
ExpiryTime = DateTimeOffset.Now.AddMinutes(10),
ReferenceId = Guid.NewGuid().ToString("N"),
TimeStamp = DateTimeOffset.Now,
};var client = new ProactiveEventsClient(
ProactiveEventsClient.EuropeEndpoint, token ,true);
// Change true to false for a live environment
await client.Send(request);In the constructor of the function/API setup place the following code
new ProactiveSubscriptionChangedRequestHandler().AddToRequestHandler();and then you can check your request type
if (input.Request is ProactiveSubscriptionChangedRequest request)
{
var remainingEventTypes = request.Subscriptions;
}
