Sending Notifications from SAP BTP applications to the SAP Fiori Launchpad

In this post, I introduce you to a brand-new feature for SAP BTP apps – sending user notifications to the SAP Fiori Launchpad. Your business apps can use this capability to inform end-users about events that require their attention – and to offer them a direct option to respond.

Nowadays, it’s hard to think of any application that does not make use of notifications in one form on the other – especially in the enterprise context where many items need to be acknowledged by multiple users. A possible scenario for such an application could be a leave request application. End-users can enter the dates they want to enjoy some well-deserved time off and add one or more approvers. When the user hits “Submit”, the data is persisted, and one or more notifications are displayed in the SAP Fiori Launchpads of the approvers. From there, they could directly approve or reject the request or navigate to the SAP Fiori app to see all requests in a table.


A leave request application that makes use of notifications

Note that the feature described here is only applicable to the SAP Launchpad service and the SAP Cloud Portal service – both available in SAP BTP.

Disclaimer: This leave request app is only used for display here. If you are writing your own leave request app, it might make sense to leverage the SAP Workflow service to model the approval process.


Notifications in the SAP Fiori Launchpad

The launchpad comes with all the capabilities you would expect from a notification feature. Notifications consist of, among other properties, a translatable title, a translatable description, a timestamp, and a priority level. This priority determines whether the notification will pop up on arrival or if it will just be indicated in the shell bar header.

You can see all active notifications when you click on the notification item from the shell bar. This view also allows you to group the notifications by date, type, or by priority.


The notifications popover

This popup also enabled you to remove notifications with the x button or see available follow-up actions behind the ellipsis (…) button. Follow-up actions consist of a translatable string and go beyond a simple approve/reject; they instead trigger an HTTP request to your backend, allowing you to execute any code.

Your application can create notifications and notification types via a simple CRUD interface, e.g., send an HTTP POST request to create a notification type and send another one to create a notification of this type. Be assured that there are plenty of options for you as a developer, e.g., deciding which values of the notification contain confidential data and which ones don’t. Have a look at the developer documentation to find the complete list of properties and features.


This hands-on will cover a simple scenario in which we trigger a notification from our local development setup. As our web app displays products and their availability, we will trigger notifications for products low on supply.

Seconds after the script runs, we will see a notification in the SAP Fiori Launchpad on SAP BTP. A click on this notification will open an SAP Fiori list report application that shows us various products from the Northwind service.

0. Preparation

But before we start, you need to install a few tools. Install Node.js, mbt, git, and the Cloud Foundry CLI (incl the MultiApps plugin) if you haven’t done so. In case you need help, I recommend following this tutorial group that contains step-by-step guides.

If you don’t want to (or cannot) install all these tools, use the SAP Business Application Studio, which already comes with all the needed tools out of the box.

In either case, you also need to subscribe to the SAP Launchpad service and create a launchpad site.

1. Clone and deploy an SAP Fiori app

We won’t implement a full SAP Fiori app to keep things simple and focus only on sending notifications. Therefore, we’ll make use of a well-established sample application from GitHub.

git clone
cd managed-html5-runtime-fiori-mta
npm install
npm run build
npm run deploy:cf

Check out the full readme on GitHub to learn more about this sample application.

2. Add the sample app to the launchpad

Follow this tutorial here to integrate the SAP Fiori app you just deployed in the SAP Launchpad service. Be aware that the application’s name doesn’t match the screenshots from the tutorial – you should select the app with the title “Fiori App” and the ID “” instead.

Once that’s done, you should see a list report application that displays product information.

3. Enable notification for custom applications on SAP BTP

To enable custom apps to publish notifications, they need to send data to the service via a destination.

Follow this guide to generate the notification service’s credentials and create a destination based on these credentials.


Launchpad site settings in the admin UI.


Don’t forget to enable the “Show Notifications” settings of the Launchpad site that you want to use.

4. Download service instance keys

Run the following commands to create service keys for existing services instances – one for the xsuaa service instance and the other for the destination service instance.

If you wonder where these service instances are coming from, you created them when you deployed the web app in step 1.

cf create-service-key managed-fiori-uaa uaa-key 
cf create-service-key managed-fiori-destination destination-key
cf service-key managed-fiori-uaa uaa-key 
cf service-key managed-fiori-destination destination-key

You’ll notice that the last two commands print a JSON object that contains the service keys. Copy these JSON objects into a new file with the name default-env.json:

		"destination": [
		"xsuaa": [

We’ll parse this file later to inject the service keys into our local application.

6. Write files

First, we need to define the dependencies and the main file of this project. To do this, let’s create a package.json file:

  "name": "notifications-demo",
  "scripts": {
    "start": "node create.js"
  "dependencies": {
    "@sap-cloud-sdk/core": "^1.46.0",
    "axios": "^0.21.1"

Next, we create a utility class util/NotificationAPI.js that encapsulates the APIs calls to the destination into methods. Note that we’ll use the SAP Cloud SDK here to elegantly retrieve CSRF tokens and send HTTP requests to the destination we created previously.

const { getDestination, executeHttpRequest, buildCsrfHeaders } = require("@sap-cloud-sdk/core");
const { setLogLevel } = require('@sap-cloud-sdk/util');
setLogLevel('error', 'env-destination-accessor');
setLogLevel('error', 'destination-accessor-vcap');
setLogLevel('error', 'destination-accessor-service');
setLogLevel('error', 'xsuaa-service');
setLogLevel('error', 'proxy-util');
setLogLevel('error', 'http-client');
setLogLevel('error', 'environment-accessor');

const destinationName = "SAP_Notifications";
const notificationEndpoint = "v2/Notification.svc";
const notificationTypesEndpoint = "v2/NotificationType.svc";

async function _getDestination(destinationName) {
    const notifServiceDest = await getDestination(destinationName);
    if (!notifServiceDest) {
        throw new Error(`failed to get destination: ${destinationName}`);
    return notifServiceDest;

class NotificationService {

    static async getNotificationTypes() {
        const notifServiceDest = await _getDestination(destinationName);
        const response = await executeHttpRequest(notifServiceDest, {
            url: `${notificationTypesEndpoint}/NotificationTypes`,
            method: "get"

    static async postNotificationType(notificationType) {
        const notifServiceDest = await _getDestination(destinationName);
        const csrfHeaders = await buildCsrfHeaders(notifServiceDest, { url: notificationTypesEndpoint });
        const response = await executeHttpRequest(notifServiceDest, {
            url: `${notificationTypesEndpoint}/NotificationTypes`,
            method: "post",
            data: notificationType,
            headers: csrfHeaders,

    static async postNotification(notification) {
        const notifServiceDest = await _getDestination(destinationName);
        const csrfHeaders = await buildCsrfHeaders(notifServiceDest, { url: notificationEndpoint });
        const response = await executeHttpRequest(notifServiceDest, {
            url: `${notificationEndpoint}/Notifications`,
            method: "post",
            data: notification,
            headers: csrfHeaders,

module.exports = { NotificationService };

The following file uses this utility class and adds domain-specific templates for the notifications we want to create. Namely, it defines the template for the notifications and the notification types used by these notifications. The DomainNotifications.js file itself exports the one function that we’ll reuse in a moment.

const { NotificationService } = require("./util/NotificationAPI");

const NOTIF_TYPE_KEY = "SupplyWarning";
const NOTIF_TYPE_VERSION = "1.0";

function createNotificationType() {
    return {
        NotificationTypeKey: NOTIF_TYPE_KEY,
        NotificationTypeVersion: NOTIF_TYPE_VERSION,
        Templates: [
                Language: "en",
                TemplateSensitive: "Low {{product}} supply ({{stock}} items left)",
                TemplatePublic: "Ciritical product supply detected",
                TemplateGrouped: "Limited Product Supply of {{category}}",
                TemplateLanguage: "Mustache",
                Subtitle: "{{product}} needs to be reordered"

function createNotification({ product, category, stock, recipients }) {

    return {
        OriginId: "supply-warn-backend",
        NotificationTypeKey: NOTIF_TYPE_KEY,
        NotificationTypeVersion: NOTIF_TYPE_VERSION,
        NavigationTargetAction: "display",
        NavigationTargetObject: "masterDetail",
        Priority: "High",
        ProviderId: "",
        ActorId: "",
        ActorType: "",
        ActorDisplayText: "",
        ActorImageURL: "",
        Properties: [
                Key: "product",
                Language: "en",
                Value: product,
                Type: "String",
                IsSensitive: false
                Key: "category",
                Language: "en",
                Value: category,
                Type: "String",
                IsSensitive: false
                Key: "stock",
                Language: "en",
                Value: stock,
                Type: "String",
                IsSensitive: false
        Recipients: => ({ RecipientId: recipient })),

async function publishSupplyWarningNotifications(notification) {
    const notifTypes = await NotificationService.getNotificationTypes();
    const notifType = notifTypes.find(nType => nType.NotificationTypeKey === NOTIF_TYPE_KEY && nType.NotificationTypeVersion === NOTIF_TYPE_VERSION);
    if (!notifType) {
        console.log(`Notification Type of key ${NOTIF_TYPE_KEY} and version ${NOTIF_TYPE_VERSION} was not found. Creating it...`);
        await NotificationService.postNotificationType(createNotificationType());
    return await NotificationService.postNotification(createNotification(notification));

module.exports = { publishSupplyWarningNotifications };

We already declared the main file create.js in the project descriptor above. This script uses axios to pull all product data and filters for products of a defined category that are low on supply. It then uses the exported function of the previous file to create a notification per item and finally prints a success message.

Note that you need to add your email address (the one that is linked with your SAP BTP account) in line 21 to receive the generated notifications.

const { publishSupplyWarningNotifications } = require("./DomainNotifications");
const axios = require("axios");

const categories = {
    2: "Condiments",
    4: "Dairy Products",
    6: "Meat/Poultry"

(async () => {
    try {
        const res = await axios("$format=json");

        const criticalSupplyOfCategory6 = => a.UnitsInStock <= a.ReorderLevel && a.CategoryID === 6);

        await Promise.all( => publishSupplyWarningNotifications({
            product: product.ProductName,
            category: categories[product.CategoryID],
            stock: `${product.UnitsInStock}`,
            recipients: [""]

    } catch (e) {
        if (e.response) {
            console.error(`${e.response.statusText} (${e.response.status}): ${JSON.stringify(}.`)
        } else {

7. See the notification popping up in your SAP Fiori Launchpad

Now it’s time to see everything in action. First, open the SAP Fiori Launchpad site that you created before – it doesn’t matter if you are at the landing page or an opened SAP Fiori app.

Then run the Node.js project that you just build:

npm install
npm start


Awesome! You just triggered your first notification from a custom-built app.


Alternatively to running the application locally, you can also execute an HTTP client script that does the same for you. Gregor Wolf shared his script in the comments below.


In this post, you’ve learned:

  • Where to find the credentials of the notification API
  • That you need to add a new destination for this API
  • That you can leverage the SAP Cloud SDK to consume the API
  • How to write custom logic that creates notification types and send notifications to business users

Now it’s up to you to add this logic into your business apps! Note that you won’t need the  default-env.json in a production-ready application as you can achieve the same result with a regular service binding.

  • Hi Marius Obert, thank you for the post. It was very useful!

    We are currently deploying a MTA project to Cloud Foundry which has a Fiori Launchpad Module. We added the notification service according to this tutorial.

    The problem is that the Portal automatically makes this call to the service odata:  /Notifications?$expand=Actions,NavigationTargetParams&$orderby=CreatedAt%20desc&$filter=IsGroupHeader%20eq%20false&$skip=0&$top=27

    None of those fields (CreatedAt,Actions,NavigationTargetParams) are actually fields on the Notification entity, as your post shows. Therefore, the call fails and the UI displays an error.

    Have you seen something similar before?

    Best regards,


  • Hi Marius,

    thank you for the great writeup. Have you tried to use the Cloud SDK generator to create the API Proxy from the OData Service Metadata?

    What might be helpful for others trying the notifications is this REST Client script: tests/notification.http. I've used this to get my first notifications working.

    Best regards

  • Hey Marius Obert
    pretty nice blog and thanks for sharing 🙂 it works fine

    Just two little mistakes I found, maybe you can edit them.

    1. You named the script name "test" in the package.json

     "test": "node create.js"

    And called it with with this command at step 7

    npm install
    npm start

    It needs to be "start" in the package.json or npm test in the bash command

    2. You name the js file "DomainNotification.js"

    But you require it with this snippet

    const { publishSupplyWarningNotification } = require("./DomainNotifications");

    There is a typo. The s is too much.

    Hope this don't seems picky.

    Stay healthy and regards


  • Hi, thanks a lot for share this guide.


    I have a problem when i do the "npm start" it shows a message: "Error: Unable to get access token for "destination" service! No service instance of type "destination" found". I'm usign VSCode. This is the structure of my project.


    • That probably means the content of your default-env file is wrong.

      Can you double check that you follow the same patters as mentioned above and that you pasted the correct service keys?

  • This is really a helpful blog I am really impressed with your work, keep it up the good work

    SAP Fiori is the user interface or user experience (UX) that supplements and can replace the SAP GUI.

  • Hi Marius Obert,

    thanks a lot for your inside and the hands-on explanation! I will definetly try it out!

    Just a short architecture question for clarification. The same notification logic applies also for SAP Work Zone, because it uses the Shell/Notification Service from the Launchpad Service or is there another implemenation logic needed. I hope not!

    Thanks and all the best!
