Overview

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

Service Name	Package name

Event Notifications Service | eventnotificationsv1

Prerequisites

• An IBM Cloud account.
• An Event Notifications Instance
• Go version 1.16 or above.

Installation

Install using the command.

go get -u github.com/IBM/event-notifications-go-admin-sdk

Go modules

If your application uses Go modules for dependency management (recommended), just add an import for each service that you will use in your application.
Here is an example:

import (
	"github.com/IBM/event-notifications-go-admin-sdk/eventnotificationsv1"
)

Next, run go build or go mod tidy to download and install the new dependencies and update your application's go.mod file.

In the example above, the eventnotificationsv1 part of the import path is the package name associated with the Example Service service. See the service table above to find the approprate package name for the services used by your application.

Initialize SDK

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

func initInstance() *eventnotificationsv1.EventNotificationsV1 {

    // IAM API key based authentication
	authenticator := &core.IamAuthenticator{
		ApiKey: <apikey>, // Event notifications service instance APIKey
	}

	// Set the options for the Event notification instance.
	options := &eventnotificationsv1.EventNotificationsV1Options{
		Authenticator: authenticator,
		URL:           "https://" + region + ".event-notifications.cloud.ibm.com/event-notifications",
	}
	eventNotificationsService, err := eventnotificationsv1.NewEventNotificationsV1(options)
	if err != nil {
		panic(err)
	}
	return eventNotificationsService

}
