Mailchimp: Using Webhooks to keep your customers' TicketSource records up to date

In order to keep your customer subscription status synched between  your TicketSource and Mailchimp accounts you will need to add the URL, (found in 'Settings' | 'Customers' in your TicketSource account) as a webhook for your Mailchimp mailing list.

To add a webhook follow these steps in your Mailchimp account;

• Navigate to 'Lists' in the main menu
• Choose the list you are using to manage your TicketSource customers
• In the top menu on the list page choose "Settings" | "Webhooks"
• Click 'Create A New Webhook'
• Paste the URL from your TicketSource account into the Callback URL box
• Make sure unsubscribes is checked below 'What type of updates should we send?' (TicketSource ignores all other update types)
• Under 'Only send updates when a change is made...' make sure a subscriber and account admin are ticked and the API is unticked
• click 'Save' to finalise

Mailchimp will update the customer record on TicketSource automatically when a customer unsubscribes from your mailing list.

A separate option will automatically remove a customer from your Mailchimp list if the customer record is deleted from your TicketSource account. 

To allow this to happen you will need to change a setting in your account.

• Go to the tab "Settings" | "Customers"
• Select the tick option in the middle of the page to 'Unsubscribe a customer from your Mailchimp list when their TicketSource customer record is deleted '
