NotificationServices 1.1.0

Breaking Changes in 1.1.0 while sending Notification via FCM
The current version supports the following functionalities: AWS: Send Email, SMS & Push Notification using a Basic AWS Authentication method. PLIVO: Send SMS TWILIO: Send SMS FCM: Send Push Notifications using JSON Service Account OneSignal: Send text Push Notifications with segments, filters or player ids
Configuration To start with setting the credentials use the Configuration class:
AWS

NotificationServices.Configuration.Instance.AWSAccessKey = "<your access key>";
NotificationServices.Configuration.Instance.AWSSecretKey = "<your secret key>";
NotificationServices.Configuration.Instance.AWSFCMPNSARN = "<your arn for fcm>";
NotificationServices.Configuration.Instance.AWSIOSPNSARN = "<your arn for ios>";
NotificationServices.Configuration.Instance.AWSRegionEndPoint = "<your region endpoint>";

Firebase Push notifications Set the environment variable GOOGLE_APPLICATION_CREDENTIALS in your system pointing to your service account json file. For more details visit: https://firebase.google.com/docs/admin/setup?authuser=0#add-sdk

TWILIO

NotificationServices.Configuration.Instance.TwilioAccountSID = "<your twilio account sid>";
NotificationServices.Configuration.Instance.TwilioAuthToken = "<your twilio auth token>";
NotificationServices.Configuration.Instance.TwilioFromNumber = "<your twilio number from which to send>";

PLIVO

NotificationServices.Configuration.Instance.PlivoAuthID = "<your plivo auth id>";
NotificationServices.Configuration.Instance.PlivoAuthToken = "<your plivo auth token>";
NotificationServices.Configuration.Instance.PlivoFromPhoneNumber = "<your twilio number from which to send>";

*OneSignal

NotificationServices.Configuration.Instance.OneSignalAppId = "<your OneSignal App Id>";
NotificationServices.Configuration.Instance.OneSignalAPIKey = "<your OneSignal Rest api key>";

Email
To send out emails get an instance of IEmailSender via EmailSenderFactory. You can then send the email by calling SendAWSEmailAsync. It expects 4 parameters.

• Source: The source/sender of the email. This needs to be verified in the Simple Email Service
• ToEmail: The recipient of the email
• TemplateName: The name of the template to use. You can create templates from cli and can learn more from here. https://docs.aws.amazon.com/ses/latest/DeveloperGuide/send-personalized-email-api.html
• TemplateData: The data to substitute in the Template. See the above link to see how to pass the data.

var EmailSender = EmailSenderFactory.GetAWSEmailSender();
EmailSender.SendAWSEmailAsync("noreply@services.com", "recipient@services.com", "ConfirmEmailTemplate", $"{{ \"Link\":\"{EmailCallbackUrl}\", \"Name\": \"{FirstName}\" }}");

SMS
To send out sms get an instance of ISMSSender via SMSSenderFactory. You can then send the email by calling SendSmsAsync. It expects 4 parameters.

• number: The recipient number to which the sms needs to be sent.
• message: Text Message to be sent.
• SenderId: This is an optional parameter whose default value is "Notif". The sender id to be displayed when the sms is received.
• SMSType: This is an optional parameter whose default value is "Transactional". The type of sms either it is "Promotional" or "Transactional".

AWS

var SMSSender = SMSSenderFactory.GetAWSSMSSender();
SMSSender.SendSmsAsync("<your number with country code", "Hello World");

Twilio

var SMSSender = SMSSenderFactory.GetTwilioSMSSender();
SMSSender.SendSmsAsync("<your number with country code", "Hello World");

Plivo

var SMSSender = SMSSenderFactory.GetPlivoSMSSender();
SMSSender.SendSmsAsync("<your number with country code", "Hello World");

Push Notifications
To send out push notifications get an instance of IPushNotificationSender via PushNotificationSenderFactory.
FCM You can then send the push notification by calling SendFirebasePushNotification for Firebase.

• Token: FCMToken of specific device
• Title: Title of Notification
• Body: Message of Notification
• Data: A dictionary of data to be sent in notification

var Dictionary = new Dictionary<string, string>();
Dictionary.Add("UserId", "32-34-1234");
await PushNotificationSenderFactory.GetFirebasePushNotificationSender().SendFirebasePushNotification(<FCMToken>, "Hello Title", "Hello Text", Dictionary);

You can also send to a specific topic & to multiple tokens using the methods SendFirebasePushNotificationToTopic & SendFirebasePushNotification.
AWS Before sending out a push notification via AWS a topic needs to be created for each user using CreateAWSEndpointAsync. It takes 3 parameters:

• topic: You can pass your user id here. The function will create a topic with this name in AWS.
• token: The device token which is retrieved from ios & Android installations. For iOS it will be a hexadecimal string.
• platform: Either iOS or Android. If 'iOS' an endpoint will be created in AWSIOSPNSARN. For Android an endpoint will be created in AWSFCMPNSARN

var PushNotificationSender = PushNotificationSenderFactory.GetAWSPushNotificationSender();
PushNotificationSender.CreateAWSEndpointAsync("<topic name>","<your device token>", "<platform>");

CreateAWSEndpointAsync will create a Topic with the given 'topic', Create an endpoint in the given 'platform' with the given 'token'. Internally it will also create a subscription in the topic with the newly created endpoint. The reason is explained later on. CreateAWSEndpointAsync returns a PushNotificationResponseDto which return the ARN's for Topic, Subscription & Endpoint.

You will be able to then send a push notification to a particular topic using SendAWSPushNotificationAsync. It takes 2 parameters

• TopicArn: An array of fcm device tokens to which the notifications need to be sent.
• Payload: The payload is of type SNS. The payload will be converted to a json format: { "APNS": "{"aps":{"alert": "Check out these awesome deals!","url":"www.amazon.com"} }", "APNS_SANDBOX": "{"aps":{"alert": "Check out these awesome deals!","url":"www.amazon.com"} }", "FCM": "{"data":{"message":"Check out these awesome deals!","url":"www.amazon.com"}}", }

PushNotificationSender.SendAWSPushNotificationAsync("<topic arn>", <payload>);

One Signal Sending out Text Push Notifications can be done via 3 ways. Here is a sample for sending out with Filters. You can similarly send for segments or player ids.

PushNotificationSenderFactory.GetOneSignalPushNotificationSender()
            .SendOneSignalPushNotificationWithFilters(
                new object[]{
                    new {
                        field = "tag",
                        key="email",
                        relation="=",
                        value="hello@hello.com"
                    }
                }, // The filters to which push notifications to be sent out
                new { en = "Hello Title" },  // The title for the push notification
                new { en = "Hello Sub Title" },   // The sub-title for the push notification
                new { en = "Hello Message" },  // The message for the push notification
                new { path = "/login" },  // Any Other data to be passed in
            );
