Overview

The IBM Cloud Event Notifications Node.js SDK allows developers to programmatically interact with the Event Notifications service in IBM cloud.

Service Name	Import Path
Event-Notifications	@ibm-cloud/event-notifications-node-admin-sdk/event-notifications/v1

Prerequisites

• You need an IBM Cloud account.
• Node.js >=14: This SDK is tested with Node.js versions 14 and up. It may work on previous versions but this is not officially supported.

Installation

npm install @ibm-cloud/event-notifications-node-admin-sdk

Using the SDK

For general SDK usage information, please see this link

Initialize SDK

Initialize the sdk to connect with your Event Notifications service instance.

import { EventNotificationsV1 } from '@ibm-cloud/event-notifications-node-admin-sdk/event-notifications/v1';
import { IamAuthenticator } from '@ibm-cloud/event-notifications-node-admin-sdk/auth';

const authenticator = new IamAuthenticator({
  apikey: <apikey>,  // Event notifications service instance APIKey
});

const initParameters = {
   authenticator,
  serviceUrl: "https://" + region + ".event-notifications.cloud.ibm.com/event-notifications"
}
const eventNotificationsService = EventNotificationsV1.newInstance(initParameters);

To configure service URL for Private Endpoint

If you enabled service endpoints in your account, you can send API requests over the IBM Cloud private network. In the initialisation, the base endpoint URLs of the IAM(authenticator) & Event Notification(service) should be modified to point to private endpoints.

1. Setting client options programmatically

const authenticator = new IamAuthenticator({
    apikey: <apikey>,  // Event notifications service instance APIKey
    url: "https://private.iam.cloud.ibm.com",
})

const initParameters = {
   authenticator,
  serviceUrl: "https://private." + region + ".event-notifications.cloud.ibm.com/event-notifications"
}

1. Using external configuration properties

   EVENT_NOTIFICATIONS_AUTH_URL = https://private.iam.cloud.ibm.com/identity/token

• region : Region of the Event Notifications Instance

Custom Domain Name Verification

After creation of the custom email destination with your domain name, make sure its validated for the right ownership. This can be done with SPF and DKIM verification.

• Sender Policy Framework (SPF), which is used to authenticate the sender of an email. SPF specifies the mail servers that are allowed to send email for your domain.
• DomainKeys Identified Mail (DKIM), which allows an organization to take responsibility for transmitting a message by signing it. DKIM allows the receiver to check the email that claimed to have come from a specific domain, is authorized by the owner of that domain.

const updateSpfVerifyDestinationParams = {
    instanceId : <instance-id>,
    id : <destination-id>,
    type: <verification-type>,
  };

  let res;
  try {
    res = await eventNotificationsService.updateVerifyDestination(
      updateSpfVerifyDestinationParams
    );
    console.log(JSON.stringify(res.result, null, 2));
  } catch (err) {
    console.warn(err);
  }

Templates

Template is a pre-defined layout, that may include content like images, text and dynamic content based on event. Rather than creating a new content from scratch each time, you can use a template as a base and configure them in subscription. supports the following templates:

Send Notifications Variables

• ibmenpushto - Set up the the push notifications tragets.
  • user_ids (Array of String) - Send notification to the specified userIds.
  • fcm_devices (Array of String) - Send notification to the list of specified Android devices.
  • fcm_devices (Array of String) - Send notification to the list of specified iOS devices.
  • _devices (Array of String) - Send notification to the list of specified Chrome devices.
  • firefox_devices (Array of String) - Send notification to the list of specified Firefox devices.
  • tags (Array of String) - Send notification to the devices that have subscribed to any of these tags.
  • platforms (Array of String) - Send notification to the devices of the specified platforms.
    • Pass 'G' for google (Android) devices.
    • Pass 'A' for iOS devices.
    • Pass 'WEB_FIREFOX' for Firefox browser.
    • Pass 'WEB_CHROME' for Chrome browser.
• Event Notifications SendNotificationsOptions - Event Notifications Send Notifications method.
  • instanceId (String) - Event Notifications instance AppGUID.
  • ibmenseverity (String) - Severity for the notifications. Some sources can have the concept of an Event severity. Hence a handy way is provided to specify a severity of the event.
  • id (String) - A unique identifier that identifies each event. source+id must be unique. The backend should be able to uniquely track this id in logs and other records. Send unique ID for each send notification. Same ID can be sent in case of failure of send notification. source+id will be logged in IBM Cloud Logging service. Using this combination we will be able to trace the event movement from one system to another and will aid in debugging and tracing.
  • source (String) - Source of the notifications. This is the identifier of the event producer. A way to uniquely identify the source of the event. For IBM Cloud services this is the crn of the service instance producing the events. For API sources this can be something the event producer backend can uniquely identify itself with.
  • ibmensourceid (String) - This is the ID of the source created in EN. This is available in the EN UI in the "Sources" section.
  • type (String) - This describes the type of event. It is of the form : This type is defined by the producer. The event type name has to be prefixed with the reverse DNS names so the event type is uniquely identified. The same event type can be produced by 2 different sources. It is highly recommended to use hyphen - as a separator instead of _.
  • time (String) - Time of the notifications. UTC time stamp when the event occurred. Must be in the RFC 3339 format.
  • ibmenpushto (string) - Targets for the FCM notifications. This contains details about the destination where you want to send push notification. This attribute is mandatory for successful delivery from an Android FCM or APNS destination
  • ibmenfcmbody (string) - Set payload string specific to Android platform [Refer this FCM official link].
  • ibmenapnsbody (string) - Set payload string specific to iOS platform [Refer this APNs official doc link].
  • ibmensafaribody (string) - Set payload string specific to safari notifications [Refer this Safari official doc link].
  • ibmenapnsheaders (string) - Set headers required for the APNs message [Refer this APNs official link(Table 1 Header fields for a POST request)]
  • ibmenchromebody (string) - Message body for the Chrome notifications. Refer this official documentation for more.
  • ibmenfirefoxbody (string) - Message body for the Firefox notifications. Refer this official documentation for more.
  • ibmenchromeheaders (string) - Headers for the Chrome notifications. Refer this official documentation for more.
  • ibmenfirefoxheaders (string) - Headers for the Firefox notifications. Refer this official documentation for more.
  • ibmendefaultshort (string) - Default short text for the message.
  • ibmendefaultlong (string) - Default long text for the message.
  • specversion (String) - Spec version of the Event Notifications. Default value is 1.0.

Set Environment

Find event_notifications_v1.env.hide in the repo and rename it to event_notifications_v1.env. After that add the values for,

• EVENT_NOTIFICATIONS_URL - Add the Event Notifications service instance Url.
• EVENT_NOTIFICATIONS_APIKEY - Add the Event Notifications service instance apikey.
• EVENT_NOTIFICATIONS_GUID - Add the Event Notifications service instance GUID.

Optional

• EVENT_NOTIFICATIONS_AUTH_URL - Add the IAM url if you are using IBM test cloud.
• EVENT_NOTIFICATIONS_FCM_KEY - Add firebase server key for Android FCM destination.
• EVENT_NOTIFICATIONS_FCM_ID - Add firebase sender Id for Android FCM destination.
