How to Send SMS with Node.js and Express Using MessageBird API (2025)

Step-by-step tutorial: Send SMS with Node.js, Express, and MessageBird API. Includes working code examples, async/await patterns, error handling, phone number validation, and production best practices for Node.js 22 LTS.

Send SMS with Node.js, Express, and MessageBird: Complete Tutorial

Learn how to send SMS with Node.js using Express and the MessageBird SMS API. This comprehensive tutorial shows you how to build a production-ready SMS application with modern async/await patterns, error handling, phone number validation, and step-by-step code examples for Node.js 22 LTS.

Important Platform Update (2024): MessageBird rebranded as "Bird" in February 2024. The legacy MessageBird API and Node.js SDK documented in this guide remain functional and supported, but Bird is transitioning to a next-generation platform. For WhatsApp integrations, ISVs must migrate to the Bird platform (app.bird.com) and enroll as a Tech Provider by March 31, 2025. SMS functionality continues to work on both platforms. See the Bird Connectivity Platform Migration Guide for details.

By the end of this tutorial, you'll have a functional Express API endpoint that accepts a recipient phone number and message body, then uses the MessageBird REST API to deliver SMS messages. This forms a fundamental building block for applications requiring notifications, alerts, or communication features.

Quick Reference: MessageBird SMS with Node.js

What You'll Build: REST API endpoint (/send-sms) for sending SMS via MessageBird

Technologies: Node.js 22 LTS, Express.js, MessageBird SDK v4.0.1, dotenv

Key Concepts:

  • Modern async/await pattern for API calls
  • E.164 phone number format validation
  • Environment variable management for API keys
  • Error handling and structured logging
  • Test vs. live API key usage

Prerequisites: Node.js 22 LTS, MessageBird account, API key, originator (VMN or Alphanumeric ID)

Time to Complete: 15–20 minutes

What is MessageBird SMS API and Why Use It?

MessageBird (now "Bird") is a cloud communications platform that provides a text messaging API for sending SMS programmatically. The MessageBird Node.js SDK simplifies integration with their REST API, letting you send transactional and marketing messages from your applications.

Why Send SMS Programmatically? Automate critical communications like order confirmations, appointment reminders, two-factor authentication codes, and real-time alerts – all without manual intervention. SMS messages have a 98% open rate compared to email's 20%, making them ideal for time-sensitive notifications.

Common SMS API Use Cases:

  • E-commerce: Order confirmations, shipping updates, delivery notifications
  • Healthcare: Appointment reminders, prescription alerts, patient communications
  • Authentication: Two-factor authentication (2FA), OTP codes, password resets
  • Finance: Transaction alerts, fraud notifications, account security
  • Marketing: Promotional campaigns, flash sales, event reminders

What Technologies Does This Tutorial Use?

  • Node.js 22 LTS: JavaScript runtime enabling server-side execution. Chosen for its asynchronous nature, large ecosystem (npm), and suitability for I/O-bound tasks like API interactions. Current LTS as of October 2024, supported until April 2027.
  • Express.js: Minimal and flexible Node.js web application framework. Chosen for its simplicity in setting up routes and handling HTTP requests, ideal for creating REST APIs quickly.
  • MessageBird SDK: Official Node.js library for interacting with the MessageBird SMS gateway. Simplifies making API calls to send text messages.
  • dotenv: Module to load environment variables from a .env file into process.env. Securely manages sensitive information like API keys outside of the codebase.

System Architecture:

                      +-------------------------+

Expected Outcome: A running Node.js server that exposes a /send-sms POST endpoint. Send a valid request to trigger SMS message delivery via MessageBird.

What Do You Need Before Starting?

  • Node.js and npm (or yarn): Install on your development machine. Recommended: Node.js 22 LTS (current LTS as of October 2024, supported until April 2027). Download from nodejs.org. Other supported LTS versions include Node.js 20 (Iron) and Node.js 18 (Hydrogen).
  • MessageBird Account: A free account is sufficient to start. Sign up at messagebird.com or the new bird.com platform.
  • MessageBird API Key: You need an API access key from your MessageBird dashboard. MessageBird provides both live and test API keys.
    • Live Keys: Send actual SMS messages to real phone numbers, potentially incurring costs. Use for production or real-world testing.
    • Test Keys: Validate API calls without sending actual SMS messages or incurring charges. Ideal during development to simulate SMS API integration without spending credits. Note: Test keys are not supported in the Conversations API (as of 2024).
  • MessageBird Originator: Either a purchased Virtual Mobile Number (VMN) from MessageBird or a registered Alphanumeric Sender ID (availability depends on the destination country).
  • Test Recipient Phone Number: A mobile phone number where you can receive the test SMS (when using a live API key).

Step 1: Set Up Your Node.js Express Project

Initialize your Node.js project and install the necessary dependencies.

  1. Create Project Directory: Open your terminal or command prompt and create a new directory for the project, then navigate into it.

    bash
    mkdir node-messagebird-sms
    cd node-messagebird-sms
  2. Initialize Node.js Project: Create a package.json file to manage project dependencies and scripts.

    bash
    npm init -y

    (The -y flag accepts default settings.)

  3. Install Dependencies: Install Express for the web server, the MessageBird SDK, and dotenv for environment variables.

    bash
    npm install express messagebird dotenv

    This downloads the packages, adds them to your node_modules directory, and lists them as dependencies in package.json.

    SDK Version Note: The messagebird npm package (v4.0.1, last updated in 2021–2022) remains functional for SMS operations. While the SDK hasn't received recent updates, it continues to work with the MessageBird REST API. For the latest features and the new Bird platform, consult Bird's official documentation.

  4. Create Project Files: Create the main application file and the environment configuration file.

    • On Linux/macOS:
      bash
      touch index.js .env
    • On Windows (Command Prompt):
      bash
      type nul > index.js
      type nul > .env
    • On Windows (PowerShell):
      powershell
      New-Item index.js -ItemType File
      New-Item .env -ItemType File

Your basic project structure should now look like this:

text
node-messagebird-sms/
├── node_modules/
├── .env
├── index.js
├── package-lock.json
└── package.json

Architectural Decision: Use a single index.js file for simplicity in this basic example. In larger applications, separate concerns into different files/modules (routes, controllers, services). Using .env ensures sensitive credentials like API keys aren't hardcoded in the source code, adhering to security best practices.

Step 2: Configure MessageBird API Credentials

Securely store and access your MessageBird API key and originator information.

  1. Obtain Your MessageBird API Key:

    • Log in to your MessageBird Dashboard.
    • Navigate to the "Developers" section in the left-hand sidebar.
    • Click on the "API access" tab.
    • Find both your live and test API keys here.
    • If you don't have keys, click "Add access key." Choose the mode (Live or Test).
    • Copy the appropriate access key (use the test key for initial development, switch to the live key for sending real messages). Treat these keys like passwords – keep them confidential.
  2. Obtain Your MessageBird Originator:

    • The originator is the sender ID displayed on the recipient's phone. It can be:
      • A Virtual Mobile Number (VMN): Purchase one in the "Numbers" section of the MessageBird Dashboard. This is the most reliable option for two-way communication and delivery to countries like the US.
      • An Alphanumeric Sender ID: A custom name (e.g., "My App," max 11 characters). You might need to register this via the Dashboard ("Channels" > "SMS" > "Sender IDs"). Note that Alphanumeric IDs aren't supported in all countries (e.g., the US) and can't receive replies. Check MessageBird's country restrictions documentation for details.
    • Choose the originator you intend to use. For VMNs, use the full number in E.164 format (e.g., +12025550184).
    • E.164 Format Requirement: MessageBird requires phone numbers in valid E.164 international format (country code + number, no spaces or special characters). Important: MessageBird doesn't automatically validate phone number formats. Ensure numbers are correctly formatted before submitting to the API to avoid unnecessary costs or failed deliveries. Consider using MessageBird's Lookup API for phone number validation.
  3. Configure Environment Variables: Open the .env file you created earlier and add your API key (start with the test key) and originator:

    dotenv
    # .env
    # Start with your TEST key for development
    MESSAGEBIRD_ACCESS_KEY=YOUR_TEST_API_KEY_HERE
    MESSAGEBIRD_ORIGINATOR=YOUR_VMN_OR_ALPHANUMERIC_ID_HERE
    • Replace YOUR_TEST_API_KEY_HERE with your actual test (or live) API key.
    • Replace YOUR_VMN_OR_ALPHANUMERIC_ID_HERE with your chosen MessageBird number (e.g., +12025550184) or registered Alphanumeric ID (e.g., MyApp).
  4. (Optional but Recommended) Add .env to .gitignore: If you plan to use Git for version control, create a .gitignore file and add .env to prevent accidentally committing your credentials.

    • Create the file:
      • Linux/macOS: touch .gitignore
      • Windows CMD: type nul > .gitignore
      • Windows PowerShell: New-Item .gitignore -ItemType File
    • Add the following lines to .gitignore:
      text
      # .gitignore
      node_modules
      .env

Purpose of Configuration: Using environment variables via dotenv lets the application access sensitive credentials without exposing them directly in the code. This enhances security and simplifies configuration across different deployment environments (development, staging, production). Using test keys initially prevents accidental charges and message sending during development.

Step 3: Initialize MessageBird Client with Async/Await

Write the core logic in index.js to initialize Express, load environment variables, and set up the MessageBird client using modern async/await patterns.

javascript
// index.js
'use strict';

// 1. Load environment variables
require('dotenv').config();

// 2. Import dependencies
const express = require('express');
const messagebird = require('messagebird'); // Import the main function

// 3. Initialize MessageBird client
const ACCESS_KEY = process.env.MESSAGEBIRD_ACCESS_KEY;
const ORIGINATOR = process.env.MESSAGEBIRD_ORIGINATOR;

if (!ACCESS_KEY || !ORIGINATOR) {
  console.error('Error: MESSAGEBIRD_ACCESS_KEY and MESSAGEBIRD_ORIGINATOR must be set in the .env file.');
  process.exit(1); // Exit if essential config is missing
}

// Initialize the client using the function directly with the key
const mbClient = messagebird(ACCESS_KEY);

// 4. Initialize Express app
const app = express();
const PORT = process.env.PORT || 3000; // Use port from env or default to 3000

// 5. Middleware to parse JSON request bodies
app.use(express.json());

// --- API Endpoint will be added below ---

// Basic root route for testing server is up
app.get('/', (req, res) => {
  res.send('SMS Sending Server is running!');
});

// 6. Start the server
app.listen(PORT, () => {
  console.log(`Server running on http://localhost:${PORT}`);
  console.log(`Using MessageBird Originator: ${ORIGINATOR}`);
  // Determine if using test or live key based on key prefix (common pattern, verify if MessageBird follows this)
  const keyType = ACCESS_KEY.startsWith('test_') ? 'TEST' : 'LIVE';
  console.log(`Using ${keyType} API Key.`);
});

Explanation:

  1. require('dotenv').config();: Loads variables from the .env file into process.env. Call this early.
  2. Imports the express framework and the main initialization function from the messagebird SDK.
  3. Retrieves the API key and originator from process.env. Includes a check to ensure these critical variables are set, exiting gracefully if not. Initializes the MessageBird client by calling the imported function with the API key (messagebird(ACCESS_KEY)).
  4. Creates an Express application instance and defines the port it listens on.
  5. app.use(express.json());: Adds middleware to automatically parse incoming JSON request bodies, making req.body available in route handlers.
  6. Starts the Express server, logging confirmation messages to the console, including the originator and whether a test or live key is likely being used.
  7. Includes a simple GET / route to check if the server is running via a browser or curl.

Step 4: Create the SMS API Endpoint in Express

Create the /send-sms endpoint that handles POST requests to send messages using modern async/await syntax for asynchronous API calls.

Add the following code inside index.js, just before the app.listen call and after the app.get('/') route:

javascript
// index.js (continued)

// --- API Endpoint ---
// Use async function to allow await
app.post('/send-sms', async (req, res) => {
  // 1. Extract recipient and message body from request
  const { recipient, message } = req.body;

  // 2. Basic Input Validation
  // Note: Add more robust validation, especially for the recipient format (E.164)
  if (!recipient || !message) {
    console.warn({ timestamp: new Date().toISOString(), level: 'WARN', message: 'Validation Error: Missing recipient or message.', requestBody: req.body });
    return res.status(400).json({
      status: 'error',
      message: 'Recipient phone number (E.164 format) and message body are required.',
    });
  }

  // 3. Prepare MessageBird parameters
  const params = {
    originator: ORIGINATOR,
    recipients: [recipient], // Must be an array
    body: message,
  };

  console.log(`Attempting to send SMS to ${recipient} from ${ORIGINATOR}`);

  try {
    // 4. Send the message using MessageBird SDK with await
    const response = await mbClient.messages.create(params);

    // 5. Handle successful sending
    // Note: Verify the exact structure of 'response' against current SDK documentation
    console.info({ timestamp: new Date().toISOString(), level: 'INFO', message: 'MessageBird API Success', response: response, requestParams: params });
    res.status(200).json({
      status: 'success',
      message: 'SMS submitted successfully to MessageBird!',
      messageId: response.id, // Include the MessageBird message ID
      recipients: response.recipients.items.map(item => ({
        recipient: item.recipient,
        status: item.status,
        statusDatetime: item.statusDatetime,
      })),
    });

  } catch (err) {
    // 6. Handle MessageBird API errors
    console.error({ timestamp: new Date().toISOString(), level: 'ERROR', message: 'MessageBird API Error', error: err, requestParams: params });

    // Safely extract error description(s)
    let errorDetails = 'Unknown API error';
    if (err.errors && Array.isArray(err.errors)) {
      errorDetails = err.errors.map(e => e.description || 'Unknown error code').join(', ');
    } else if (err.message) {
        errorDetails = err.message;
    }

    // Determine appropriate status code (e.g., 4xx for client errors, 5xx for server errors)
    // MessageBird errors often have status codes, but default to 500 if unsure.
    const statusCode = err.statusCode || 500;

    return res.status(statusCode).json({
      status: 'error',
      message: `Failed to send SMS via MessageBird: ${errorDetails}`,
      // DO NOT include raw error object (`err`) in production responses for security.
      // It's logged above for debugging.
    });
  }
});

// --- End of API Endpoint ---

// 6. Start the server
// ... (app.listen call remains here) ...

Explanation:

  1. Endpoint Definition: app.post('/send-sms', async (req, res) => {…}) defines an async route handler for POST requests at /send-sms.
  2. Input Extraction & Validation: Extracts recipient and message. Basic validation checks for presence. A comment reminds you to add stricter validation (e.g., E.164 format check for recipient). Returns 400 Bad Request on failure.
  3. Parameter Preparation: Creates the params object for the SDK.
  4. Send the Message: Uses a try…catch block for asynchronous operations. await mbClient.messages.create(params) calls the SDK function and pauses execution until the promise resolves or rejects.
  5. Success Handling (try block): If the await succeeds, logs the success and sends a 200 OK response with relevant details from the response object (like message ID and recipient status). A comment notes that the exact response structure should be confirmed in the SDK docs.
  6. Error Handling (catch block): If await rejects (an error occurs), the catch(err) block executes. Logs the error details for debugging, then attempts to parse a user-friendly error message from err.errors (checking it's an array) or falls back to err.message. Determines an appropriate HTTP status code (using err.statusCode if available, otherwise 500). Finally, sends the formatted error response to the client, omitting the raw err object for security.

Step 5: Implement Error Handling for SMS Delivery

The code now includes:

  • Configuration Errors: Checks for missing .env variables on startup.
  • Input Validation Errors: Returns a 400 Bad Request if recipient or message are missing.
  • MessageBird API Errors: Uses try…catch to handle errors from the SDK call. It logs detailed errors server-side and returns a structured, safe error message to the client with an appropriate status code.

Production Improvements:

  • More Specific Validation: Use a library like joi or express-validator for robust validation (e.g., checking E.164 format, message length limits). Add this validation right after extracting req.body. Critical: Since MessageBird doesn't validate phone numbers automatically, implementing strict E.164 validation prevents failed deliveries and wasted credits.
  • Phone Number Validation Service: Integrate MessageBird's Lookup API to validate phone numbers before sending. This verifies the number is valid, active, and routable, reducing delivery failures.
  • Structured Logging: Replace console.log/warn/info/error with a dedicated logging library (like winston or pino) for structured JSON logs, controllable log levels, and outputting to files or services.
  • Error Tracking Services: Integrate services like Sentry or Bugsnag to automatically capture and report errors.
  • Security Headers: Use middleware like helmet to set various HTTP headers for security.
  • Rate Limiting: Implement rate limiting on the endpoint (e.g., using express-rate-limit) to prevent abuse.
  • Retry Mechanisms: For transient network errors or specific MessageBird errors (like rate limits), implement a retry strategy with exponential backoff. Be cautious not to cause duplicate messages.

Example of adding E.164 format validation:

javascript
// Inside /send-sms route, after extracting recipient
const e164Regex = /^\+[1-9]\d{1,14}$/; // Basic E.164 regex (ITU-T E.164 standard)
if (!recipient || !message || !e164Regex.test(recipient)) {
  console.warn('Validation Error: Invalid input.', { recipient, message });
  return res.status(400).json({
    status: 'error',
    message: 'Recipient phone number (must be valid E.164 format like +1234567890) and message body are required.',
  });
}

Step 6: Test Your SMS Endpoint with cURL

Run the server and test the endpoint using curl.

  1. Run the Application: Open your terminal in the project directory (node-messagebird-sms/) and run:

    bash
    node index.js

    You should see output:

    text
    Server running on http://localhost:3000
    Using MessageBird Originator: YOUR_VMN_OR_ALPHANUMERIC_ID_HERE
    Using TEST API Key. // Or LIVE depending on your .env
  2. Send a Test SMS using curl: Open another terminal window. Replace +1xxxxxxxxxx with your actual recipient phone number (in E.164 format) and modify the message text if desired.

    bash
    curl -X POST http://localhost:3000/send-sms \
         -H "Content-Type: application/json" \
         -d '{
               "recipient": "+1xxxxxxxxxx",
               "message": "Hello from Node.js and MessageBird! Sent on Jan 10, 2024."
             }'
  3. Check the Results:

    • Terminal 1 (Server Logs): Check log output indicating the attempt and the success or failure response from MessageBird.
      • Success Example (Test Key): You'll see a success log, but no SMS is actually sent.
      • Success Example (Live Key): You'll see a success log, and an SMS should arrive.
        text
        Attempting to send SMS to +1xxxxxxxxxx from YOUR_ORIGINATOR
        {"timestamp":"...","level":"INFO","message":"MessageBird API Success", … }
      • Error Example (e.g., invalid recipient):
        text
        Attempting to send SMS to +1invalidnumber from YOUR_ORIGINATOR
        {"timestamp":"...","level":"ERROR","message":"MessageBird API Error", … errors: [ { code: 21, description: 'Invalid recipient.', parameter: 'recipients' } ] …}
    • Terminal 2 (curl Output):
      • Success:
        json
        {
          "status": "success",
          "message": "SMS submitted successfully to MessageBird!",
          "messageId": "mb_message_id_string",
          "recipients": [
            {
              "recipient": 1xxxxxxxxxx,
              "status": "sent",
              "statusDatetime": "…"
            }
          ]
        }
      • Input Validation Error (missing field or invalid format):
        json
        {
          "status": "error",
          "message": "Recipient phone number (must be valid E.164 format like +1234567890) and message body are required."
        }
      • MessageBird API Error (e.g., bad key): json { "status": "error", "message": "Failed to send SMS via MessageBird: Authentication failed" }
    • Recipient Phone: If using a live API key and the call was successful, receive the SMS on the specified recipient phone within a few seconds. If using a test key, no SMS arrives.

Troubleshooting Common SMS Integration Issues

  • Error: MESSAGEBIRD_ACCESS_KEY… must be set: Ensure your .env file exists in the project root, is correctly named (.env), and contains the MESSAGEBIRD_ACCESS_KEY and MESSAGEBIRD_ORIGINATOR variables with valid values. Restart the Node.js server after editing .env.
  • 400 Bad Request Response: Verify curl has -H "Content-Type: application/json" and the -d payload is valid JSON with recipient (in E.164 format) and message. Check server logs for validation errors.
  • 401, 403, or 500 Error with "Authentication failed", "Invalid Signature", or similar:
    • Your MESSAGEBIRD_ACCESS_KEY in .env is incorrect. Verify it in the MessageBird Dashboard.
    • You're using a test key for an operation requiring a live key, or vice-versa. Note that test keys don't work with the Conversations API (as of 2024). Ensure you're using the correct key type for your needs. Double-check the copied key value.
  • Error with "Invalid originator": The MESSAGEBIRD_ORIGINATOR in .env is incorrect, not registered, or not permitted for the destination country (especially Alphanumeric IDs). Check format (E.164 for numbers) and status in the MessageBird Dashboard. See MessageBird's Originator article.
  • Error with "Invalid recipient" or "Number not routable": The recipient number is invalid, not in E.164 format (+ country code + number), or for a destination MessageBird can't reach. Remember: MessageBird doesn't validate phone numbers automatically – ensure proper E.164 formatting before submission to avoid costs from invalid numbers.
  • Error with "Insufficient balance": Your MessageBird account needs credits (only applies when using a live key). Add funds via the Dashboard.
  • SMS Not Received Despite Success Response (Live Key):
    • Verify the recipient number is in valid E.164 format.
    • Wait a few minutes (carrier delays).
    • Check MessageBird Dashboard logs ("SMS" > "SMS Overview") for detailed delivery status (e.g., carrier rejection).
    • Ensure the phone has signal and isn't blocking unknown senders.
    • Alphanumeric IDs might not be supported by the destination carrier (e.g., US/Canada often require local numbers). Try a VMN.
  • Rate Limiting: High volume sending might hit MessageBird rate limits. Implement queuing and backoff strategies.
  • SDK Response Structure: Verify the exact structure of the success (response) and error (err) objects from mbClient.messages.create against the current official MessageBird Node.js SDK documentation, as it can change over time.
  • Platform Migration: If you're building new WhatsApp integrations or planning long-term projects, review Bird's migration documentation to understand the transition from MessageBird to Bird platforms.

Running Your Node.js SMS Application

To run the application, navigate to the project directory in your terminal and execute:

bash
node index.js

The server starts and remains running until you stop it (usually with Ctrl + C).

Frequently Asked Questions

What is the difference between MessageBird test and live API keys?

Test keys validate your API integration without sending actual SMS messages or incurring charges. They're ideal for development and testing. Live keys send real SMS messages to phone numbers and consume account credits. Note that test keys don't work with the Conversations API as of 2024.

How do you format phone numbers for MessageBird SMS API?

MessageBird requires phone numbers in E.164 international format: a plus sign (+) followed by the country code and subscriber number (1–15 digits total). Example: +12025550184 for a US number. Remove all spaces, dashes, and parentheses. Important: MessageBird doesn't validate formats automatically – you must validate before submission.

What Node.js version should you use with MessageBird?

Use Node.js 22 LTS (recommended as of October 2024, supported until April 2027). Other supported LTS versions include Node.js 20 (Iron) and Node.js 18 (Hydrogen). The MessageBird SDK (v4.0.1) works with all current LTS versions.

How do you handle MessageBird API errors in Node.js?

Use try…catch with async/await to handle errors. Extract error details from err.errors array or err.message. Return appropriate HTTP status codes (400 for client errors, 500 for server errors). Log detailed errors server-side but return safe, user-friendly messages to clients. Never expose raw error objects in production responses.

Can you use MessageBird with Express.js async/await?

Yes. Define route handlers as async functions and use await with mbClient.messages.create(). Wrap in try…catch for error handling. This modern pattern is cleaner than callback or promise chains and is the recommended approach for Node.js API development.

What is the MessageBird originator and why does it matter?

The originator is the sender ID displayed on the recipient's phone. It can be a Virtual Mobile Number (VMN) purchased from MessageBird or an Alphanumeric Sender ID (custom name, max 11 characters). VMNs work globally and enable two-way communication. Alphanumeric IDs aren't supported in all countries (e.g., US) and can't receive replies.

Conclusion and Next Steps

You've successfully built a Node.js Express application capable of sending SMS messages using the MessageBird API and modern JavaScript practices. You learned how to set up a project, manage API keys (test vs. live), create an API endpoint using async/await, interact with the MessageBird SDK, and handle errors securely.

Next Steps & Potential Improvements:

  • Robust Input Validation: Implement stricter validation (E.164 format, message length) using libraries like joi or express-validator. Consider integrating MessageBird's Lookup API for real-time phone number validation.
  • User Interface: Build a front-end to interact with your SMS API.
  • Asynchronous Processing: Use a message queue (e.g., RabbitMQ, Redis/BullMQ) for high-volume sending to improve responsiveness and manage retries.
  • Database Integration: Store message logs or application data.
  • Advanced MessageBird Features: Explore receiving messages (webhooks), delivery status checking, templates, MMS.
  • Enhanced Security: Add API authentication, rate limiting (express-rate-limit), security headers (helmet).
