What is the method to obtain the HTTP Authorization header?

edit

The HTTP Authorization header is typically obtained by adding it to the request header of an HTTP request. The syntax for the Authorization header is:

Authorization: <type> <credentials>

The type field specifies the type of authentication being used, such as Basic or Bearer. The credentials field contains the actual authentication information, such as a username and password or a token.

The specific method for obtaining the Authorization header will vary depending on the authentication scheme being used and the programming language or tool being used to send the HTTP request. In most cases, the authentication information will be provided in the form of a token or credentials that are generated or obtained through some kind of authentication process. Once the token or credentials are obtained, they can be added to the Authorization header and included in the HTTP request.
