**Architectural Overview** This Make.com scenario triggers when a Shopify order is paid, routes the customer data to a Mailchimp list, and updates the deal stage in HubSpot. **Node Sequence** 1. Trigger: Shopify (Watch Orders - 'Paid' status) 2. Action 1: Mailchimp (Add/Update Subscriber) 3. Action 2: HubSpot CRM (Update a Deal) **API & Data Mapping Logic** *Shopify to Mailchimp:* Map `Email` to `{{1.email}}` Map `First Name` to `{{1.customer.first_name}}` *Shopify to HubSpot:* Map `Amount` to `{{1.total_price}}` Map `Deal Stage` to `closedwon` **Error Handling & Edge Cases** Add an Error Handler (Ignore) to the Mailchimp node. If a user is already subscribed and throws a 400 error, the workflow will ignore it and successfully proceed to update HubSpot without halting the scenario.
