Send Bearer Token with Axios

by | Mar 7, 2024

In today’s digital world, securing your data and ensuring safe communication between your application and server is crucial. One common method of achieving this is by using tokens. Tokens act as a form of authentication, allowing only authorized users to access certain resources. If you’re using Axios, a popular JavaScript library for making HTTP requests, there is one straightforward approach on how to send bearer token with Axios to your requests . In this guide, we’ll walk through the process step by step.

How to Send Bearer Token with Axios

Step 1

Obtain Your Token Before you can add a token to your Axios requests, you need to obtain one. This typically involves authenticating with your server using credentials such as a username and password, and receiving a token in return. This token serves as proof of your identity and grants you access to protected resources.

Step 2

Set Up Axios If you haven’t already done so, you’ll need to install Axios in your project. You can do this using npm or yarn:

npm install axios

Once Axios is installed, you can import it into your code:

import axios from 'axios';

Step 3

Configure Axios with Your Token To add your token to every Axios request, you can use Axios interceptors. Interceptors allow you to intercept requests or responses before they are handled by the then or catch methods. Here’s how you can set up an interceptor to add your token to each request:

// Assuming you have stored your token in localStorage
const token = localStorage.getItem('token');

// Add a request interceptor
  function(config) {
    // Add the token to the request headers
    config.headers.Authorization = `Bearer ${token}`;
    return config;
  function(error) {
    return Promise.reject(error);

In this code snippet:

  • We retrieve the token from localStorage. You might obtain your token from a different source, such as a cookie or a server response.
  • We use axios.interceptors.request.use() to intercept outgoing requests.
  • Inside the interceptor, we modify the request configuration (config) to include the token in the Authorization header. The token is prefixed with 'Bearer ', which is a common convention for JWT tokens.
  • We return the modified configuration to ensure the request proceeds as intended.

Step 4

Make Your Requests With Axios configured to include your token in every request, you can now make your API calls as usual. The token will automatically be added to the request headers, authenticating you with the server.

  .then(response => {
    // Handle the response
  .catch(error => {
    // Handle any errors

And that’s it! You’ve successfully added a token to your Axios requests. This simple yet powerful technique helps ensure the security of your application by authenticating users and controlling access to sensitive resources. By following these steps, you can enhance the security of your applications and protect your users’ data.
