    )

    func main() {

        // Init notifier
        notifier := notify.New()
        ctx := context.Background()

        // Provide your Mattermost server url
        mattermostService := mattermost.New("https://myserver.cloud.mattermost.com")

        // Provide username as loginID and password to login into above server.
        // NOTE: This generates auth token which will get expired, invoking this method again
        // after expiry will generate new token and uses for further requests.
        err := mattermostService.LoginWithCredentials(ctx, "someone@gmail.com", "somepassword")

        // Where to send our messages.
        mattermostService.AddReceivers("CHANNEL_ID")

        // Tell our notifier to use the Mattermost service. You can repeat the above process
        // for as many services as you like and just tell the notifier to use them.
        notifier.UseServices(mattermostService)

        // Add presend and postsend hooks that you need to execute before every requests and after
        // every response respectively. Multiple presend and postsend are executed in the order defined here.
        // refer service/http for the more info.
