what is the syntax for archiving a list member in Mailchimp via the API

The syntax for archiving a list member in Mailchimp via the API is:

bash
DELETE /lists/{list_id}/members/{subscriber_hash}

Replace `{list_id}` with the ID of the list you want to archive the member from and `{subscriber_hash}` with the MD5 hash of the lowercase version of the list member's email address.

For example:

bash
DELETE /lists/12345678/members/md5:
 <script language='JavaScript' type='text/javascript'>
 <!--
 var prefix = 'm&#97;&#105;lt&#111;:';
 var suffix = '';
 var attribs = '';
 var path = 'hr' + 'ef' + '=';
 var addy73482 = 's&#117;bscr&#105;b&#101;r' + '&#64;';
 addy73482 = addy73482 + '&#101;x&#97;mpl&#101;' + '&#46;' + 'c&#111;m';
 document.write( '<a ' + path + '\'' + prefix + addy73482 + suffix + '\'' + attribs + '>' );
 document.write( addy73482 );
 document.write( '<\/a>' );
 //-->
 </script><script language='JavaScript' type='text/javascript'>
 <!--
 document.write( '<span style=\'display: none;\'>' );
 //-->
 </script>This e-mail address is being protected from spambots. You need JavaScript enabled to view it
 <script language='JavaScript' type='text/javascript'>
 <!--
 document.write( '</' );
 document.write( 'span>' );
 //-->
 </script>

This will archive the list member with the email address `

` from the list with the ID `12345678`.
