Sending Curl Request with Bearer Token [JavaScript/AJAX Code]

To send a Bearer Token to the server using Curl, you can use the -H "Authorization: Bearer {token}" authorization header. The Bearer Token is an encrypted string that provides a user authentication framework to control access to protected resources. To send a Curl POST request, you need to pass the POST data with the -d command line option, and the authorization header and bearer token are passed with the -H command line option. In this Curl Request With Bearer Token Authorization Header example, we send a GET request to the ReqBin echo URL.

What is Curl?

Curl is a well-known command-line tool for transferring data between servers, designed to work without user intervention. Curl can upload or download data using popular protocols including HTTP, HTTPS, SCP, SFTP, and FTP with Curl. Curl is used for API testing, has built-in support for proxies, SSL, HTTP cookies. Curl runs on Linux, Windows, and macOS platforms.

What is the Authorization Header?

HTTP provides a built-in framework for controlling access and authentication to protected resources. The authorization request header contains the credentials for authenticating the HTTP client to the server. The most commonly used authorization headers are Basic Auth and Bearer Token headers.

Authorization Header Syntax
Authorization: Basic {base64string}
Authorization: Bearer {token}

What is the Bearer Authorization Token?

HTTP provides a user authentication framework to control access to protected resources. Bearer authentication (also called token authentication) is done by sending security tokens in the authorization header. The Bearer Token is a string that is not intended to be used by clients. Some servers will issue bearer tokens, short lines of hexadecimal characters, while others may use structured tokens like JWTs. The client must send this token back to the server in every authorization header when requesting protected resources.
