I need an API-driven email workflow inside my Wix store so customers automatically receive an email when an order is placed and again when their shipment goes out. The process must rely on Wix webhooks (or an equivalent Velo/HTTP-functions setup), integrate with an email service like SendGrid, Mailchimp, or Postmark, and run entirely server-side for reliability and speed. Please outline, step by step, how you will: • Capture the order-placed and shipping-confirmation events • Authenticate securely with Wix APIs and the chosen email service • Map dynamic order data into editable email templates • Log errors and let me monitor send success without extra overhead Deliverables • A fully tested automation for both triggers, live in my Wix site • Two customizable email templates already wired to the workflow • Hand-off notes explaining endpoints, environment variables, and template editing Acceptance criteria • Emails arrive within one minute of each trigger in 95 % of tests • No duplicate or missed sends during load testing • Workflow passes a real purchase test in my store before final sign-off Attach a detailed project proposal covering timeline, milestones, and any third-party costs so I can compare approaches efficiently. Past work samples are welcome but the main decision factor will be the clarity and completeness of your plan.
