Sending Authorization Bearer Token Header [JavaScript/AJAX Code]

To send a request with the Bearer Token authorization header, you need to make an HTTP request and provide your Bearer Token in the "Authorization: Bearer {token}" HTTP header. A Bearer Token is a cryptic string typically generated by the server in response to a login request. The client must send this Bearer Token in the Authorization header on every request it makes to obtain a protected resource. For security reasons, Bearer Tokens are only sent over HTTPS (SSL). In this JavaScript/AJAX Authorization Bearer Token example, we send a request to the ReqBin URL with the authorization bearer token header.

What is HTTP?

HTTP is a network data transfer protocol used to transfer data between HTTP clients (browsers, mobile apps, etc.) and servers. HTTP is based on a client-server architecture and built on messages called requests and responses. The client generates a request and sends it to the server, where the server processes this request and generates a response by sending it back to the client.

What is the Authorization Header?

The Authorization request header includes credentials to authenticate the client on the server. HTTP provides a built-in framework for user authentication and controlling access to protected resources.

What is Bearer Authorization?

Bearer Authentication (also called token authentication) is a mechanism used to authorize clients by sending a security token with every HTTP request we make to the server. The server usually generates a bearer token in response to a login request and sends it to the client. The client stores it on the user's device (for example, the browser can save the token in local storage). The client sends the bearer token back to the server on every request to the protected resource (in the Authorization header).

Bearer Token Authorization Syntax

Following is the syntax for sending a request with an Authorization Bearer Header:

Bearer Token Authorization Syntax
GET /echo/get/json HTTP/1.1
Authorization: Bearer {token}
Host: reqbin.com

Where:
  • Authorization: standard HTTP authorization header
  • Bearer: indicates a bearer token authorization scheme
