mailchimp désinscription avec le serveur nœud js

Question

J'ai un problème avec mailchimp processus de désinscription. S'il vous plaît pouvez-vous me donner le chemin pour le processus de désabonnement. Comment mettre exactement dans la liste de désinscription et quels fichiers je devrais demander. Et comment je connais les différences que l'email devrait être mis dans la liste de désinscription.

mailchimp.post('/lists/{id}', { 
     email_address : "email@email.com" 
    }) 
     .then(function(results) { 
     console.log(results) 
     }) 
     .catch(function (err) { 
     console.log(err) 
     });
