In case you are using any client-side JavaScript framework, authorization headers can be sent for the desired interaction with WP API. The DELETE request would then be sent by another jQuery.ajax() method like this:

    beforeSend: function ( xrh ) { 
        xrh.setRequestHeader( 'Authorization', 'Basic ' +          Base64.encode( 'username:password' ) ); 
    success: function( data, txtStatus, xrh ) {

        console.log( xrh.status ); 

In this example, the BASE64 is considered to be an object used for encoding a string.

This is a way of cross-browser encoding of a string within JavaScript.

The Authorization header was used in the preceding example, and the setRequestHeader() method within xhr object was passed as an argument to the beforeSend...
