Unsubscribe users from Action Network when they unsubscribe from Mailchimp

“Anytime a user unsubscribes in Mailchimp, send a GET request to Action Network using Webhooks by Zapier to get the identifier for that subscriber in Action Network based on their email address. Then send a PUT request to Action Network using the custom request option in Webhooks by Zapier to unsubscribe that user in Action Network. This Zap is useful if you are migrating from Mailchimp to Action Network and want to make sure that any users who unsubscribe in Mailchimp after the migration is done will also be unsubscibed in Action Network.”
