Custom HTTP Authorization Header

People also ask

How do I create an Authorization header?

The command requires the valid user name and password (or API token) in the application to which you want to connect, and it encodes the credentials with base64. In the Authorization Header field, you enter the word "Basic" (which is the Authorization header type), a space, and then the base64-encoded credentials.

How do I change the Authorization header in URL?

It is indeed not possible to pass the username and password via query parameters in standard HTTP auth. Instead, you use a special URL format, like this: http://username:[email protected]/ -- this sends the credentials in the standard HTTP "Authorization" header.

What is HTTP Authorization header?

The HTTP Authorization request header can be used to provide credentials that authenticate a user agent with a server, allowing access to a protected resource. The Authorization header is usually, but not always, sent after the user agent first attempts to request a protected resource without credentials.


The format defined in RFC2617 is credentials = auth-scheme #auth-param. So, in agreeing with fumanchu, I think the corrected authorization scheme would look like

Authorization: FIRE-TOKEN apikey="0PN5J17HBGZHT7JJ3X82", hash="frJIUN8DYpKDtOLCwo//yllqDzg="

Where FIRE-TOKEN is the scheme and the two key-value pairs are the auth parameters. Though I believe the quotes are optional (from Apendix B of p7-auth-19)...

auth-param = token BWS "=" BWS ( token / quoted-string )

I believe this fits the latest standards, is already in use (see below), and provides a key-value format for simple extension (if you need additional parameters).

Some examples of this auth-param syntax can be seen here...

Put it in a separate, custom header.

Overloading the standard HTTP headers is probably going to cause more confusion than it's worth, and will violate the principle of least surprise. It might also lead to interoperability problems for your API client programmers who want to use off-the-shelf tool kits that can only deal with the standard form of typical HTTP headers (such as Authorization).


No, that is not a valid production according to the "credentials" definition in RFC 2617. You give a valid auth-scheme, but auth-param values must be of the form token "=" ( token | quoted-string ) (see section 1.2), and your example doesn't use "=" that way.


Old question I know, but for the curious:

Believe it or not, this issue was solved ~2 decades ago with HTTP BASIC, which passes the value as base64 encoded username:password. (See http://en.wikipedia.org/wiki/Basic_access_authentication#Client_side)

You could do the same, so that the example above would become:
