🚀 Send a notification

Prerequisite

• A NotificationAPI account - sign up for free
• A configured notification in the dashboard (new accounts already have a demo notification)

Overview

Your team, even non-technical members, can use our dashboard to configure and design your standard notifications without any coding knowledge. For example, they would configure an alert to go over email and completely design its content, subject, etc.

Then, through our SDKs or API, your back-end lets us know when to send this notification to a user. We then take care of the rest.

Let's learn...

Step 1: Setup the SDK

Node

Install the node package using one of the following package managers:

npm install notificationapi-node-server-sdk

yarn add notificationapi-node-server-sdk

pnpm add notificationapi-node-server-sdk

Python

pip install notificationapi_python_server_sdk

PHP

composer require notificationapi/notificationapi-php-server-sdk

Go

go get github.com/notificationapi-com/notificationapi-go-server-sdk

C#

Install the package:

dotnet add package NotificationAPI --version 0.5.0

Java

Add the following dependency to your Maven project:

<dependency>
    <groupId>com.notificationapi</groupId>
    <artifactId>notificationapi-java-server-sdk</artifactId>
    <version>0.2.0</version>
</dependency>

For optimal functionality, you'll also need the following dependencies:

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.14</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.15.2</version>
</dependency>

Ruby

# Create the following class in your application

require 'net/http'
require 'json'
require 'base64'
require 'openssl'

class NotificationAPI
  def initialize(client_id, client_secret)
    # if in the CA region, use 'https://api.ca.notificationapi.com'
    # if in the EU region, use 'https://api.eu.notificationapi.com'
    @base_url = 'https://api.notificationapi.com'
    @client_id = client_id
    @auth_token = Base64.strict_encode64("#{client_id}:#{client_secret}")
    # if in the CA region, use 'api.ca.notificationapi.com'
    # if in the EU region, use 'api.eu.notificationapi.com'
    @http_client = Net::HTTP.new('api.notificationapi.com', 443)
    @http_client.use_ssl = true
  end

  def send(request)
    payload = request.to_json
    response = @http_client.post(
      "/#{@client_id}/sender",
      payload,
      {
        'Content-Type' => 'application/json',
        'Authorization' => "Basic #{@auth_token}"
      }
    )
    response.body
  end

  def retract(request)
    payload = request.to_json
    response = @http_client.post(
      "/#{@client_id}/sender/retract",
      payload,
      {
        'Content-Type' => 'application/json',
        'Authorization' => "Basic #{@auth_token}"
      }
    )
    response.body
  end

  def identify_user(user_id, user_data)
    digest = OpenSSL::Digest::SHA256.new
    hmac = OpenSSL::HMAC.digest(digest, @client_secret, user_id)
    hashed_user_id = Base64.strict_encode64(hmac)
    custom_auth = Base64.strict_encode64("#{@client_id}:#{user_id}:#{hashed_user_id}")

    send_request('POST', "users/#{URI.escape(user_id)}", user_data, custom_auth)
  end

  def create_sub_notification(notification_id, sub_notification_id, title)
    payload = { title: title }
    send_request('PUT', "notifications/#{notification_id}/subNotifications/#{sub_notification_id}", payload)
  end

  def delete_sub_notification(notification_id, sub_notification_id)
    send_request('DELETE', "notifications/#{notification_id}/subNotifications/#{sub_notification_id}")
  end

  def update_schedule(tracking_id, scheduleUpdate)
    send_request('PATCH', "notifications/#{tracking_id}", scheduleUpdate)
  end

  def delete_schedule(tracking_id)
    send_request('DELETE', "notifications/#{tracking_id}")
  end

  def set_user_preferences(user_id, user_preferences)
    send_request('POST', "user_preferences/#{user_id}", user_preferences)
  end

  private

  def send_request(method, uri, data = {}, auth = "Basic #{@auth_token}")
    payload = data.to_json
    response = @http_client.send_request(
      method,
      "/#{@client_id}/#{uri}",
      payload,
      {
        'Content-Type' => 'application/json',
        'Authorization' => auth
      }
    )
    response.body
  end

end

Step 2: Send the Notification

Our send function or POST /sender API call takes a JSON payload that specifies which notification to send and to whom. It also has a mergeTags field that you can use to personalize the notification.

Node

// import/require:
import notificationapi from 'notificationapi-node-server-sdk';
// const notificationapi = require('notificationapi-node-server-sdk').default

// initialize notificationapi (default US region)
// if in the CA region, add 'https://api.ca.notificationapi.com' after CLIENT_SECRET
// if in the EU region, add 'https://api.eu.notificationapi.com' after CLIENT_SECRET
notificationapi.init('CLIENT_ID', 'CLIENT_SECRET');

// send
notificationapi.send({
  // The ID of the notification you wish to send.
  // You can find this value from the dashboard.
  notificationId: 'order_tracking',
  // The user to send the notification to.
  user: {
    id: 'spongebob.squarepants',
    email: 'spongebob@squarepants.com' //required for email notifications
  },
  // mergeTags is to pass dynamic values into the notification design.
  mergeTags: {
    item: 'Krabby Patty Burger',
    address: '124 Conch Street',
    orderId: '1234567890'
  }
});

Python

# import
import asyncio
from notificationapi_python_server_sdk import (notificationapi)

# initialize notificationapi (default US region)
# if in the CA region, add 'https://api.ca.notificationapi.com' after CLIENT_SECRET
# if in the EU region, add 'https://api.eu.notificationapi.com' after CLIENT_SECRET
notificationapi.init("CLIENT_ID", "CLIENT_SECRET")

# send
async def send_notification():
  await notificationapi.send(
    {
      "notificationId": "order_tracking",
      "user": {
          "id": "spongebob.squarepants",
          "email": "spongebob@squarepants.com"
      },
      "mergeTags": {
          "item": "Krabby Patty Burger",
          "address": "124 Conch Street",
          "orderId": "1234567890"
      }
    }
  )

# Run the async function
asyncio.run(send_notification())

PHP

# import

$notificationapi = new NotificationAPI('CLIENT_ID', 'CLIENT_SECRET');

# send

    #The ID of the notification you wish to send. You can find this
    #value from the dashboard.
    "notificationId" => "order_tracking",
    # The user to send the notification to.
    "user" => [
        "id" => "spongebob.squarepants",
        "email" => "spongebob@squarepants.com",   # required for email notifications
        "number" => "+15005550006" # optional phone number required to send SMS notifications
    ],
    # mergeTags is to pass dynamic values into the notification design.
    "mergeTags" => [
        "item" => "Krabby Patty Burger",
        "address" => "124 Conch Street",
        "orderId" => "1234567890"
    ]

  notificationapi.Send(
    notificationapi.SendRequest{
      // The ID of the notification you wish to send. You can find this
      // value from the dashboard.
      NotificationId: "order_tracking",
