  Thanks, @kthorngren!

  It could be a little more robust (such as accepting arrays) but it works for what I need it to do!

  Another update for the plugin.

  If there is no ajax.data object then the $.extend(settings.ajax.data, params); won't have anything to extend. This could happen if settings.ajax is only a string or null.

  This checks to see if either situation exists and then changes settings.ajax into an object with the data member:

  if (typeof settings.ajax === 'string' || settings.ajax === null) {
      settings.ajax = {
          url: settings.ajax,
          data: {}
      }
  }
  
  

  Complete code:

  /**
   * Add a parameter to the current Ajax data.
   *
   * @params {object} Parameter(s) to add.
   * @returns {DataTables.Api} this
   */
  $.fn.dataTable.Api.register( 'ajax.addParam()', function ( params ) {
      return this.iterator( 'table', function ( settings ) {
          if (typeof settings.ajax === 'string' || settings.ajax === null) {
              settings.ajax = {
                  url: settings.ajax,
                  data: {}
              }
          }
          $.extend(settings.ajax.data, params);
      })   
  });
  /**
   * Delete a parameter from the current Ajax data.
   *
   * @paramKey {string} Parameter key to delete.
   * @returns {DataTables.Api} this
   */
  $.fn.dataTable.Api.register( 'ajax.deleteParam()', function ( paramKey ) {
      return this.iterator( 'table', function ( settings ) {
              delete settings.ajax.data[paramKey];
      });
  });
