I need a seamless bridge between my existing landing page and Shopify. The moment a visitor submits the form—capturing only their first Name, last name Email, Phone number, and choose niche—the system must call the Shopify API and create a customer account on the spot with 30 sellable dropshipping items. Customer will receive email notification on the creation of accountz Along with each new account, attach 30 ready-to-sell dropshipping products that I have already curated. Whether this is handled through a custom app, a private API key, or a lightweight serverless function, I’m open to your preferred stack as long as the workflow remains: 1. User completes the landing-page form. 2. Data is validated and securely transmitted. 3. Shopify instantly creates the customer account using that Name, Email, and Password. 4. The preset bundle of 30 products is added so the customer sees a stocked store as soon as they log in. Please ensure the solution is robust (Shopify Admin API, webhooks, or GraphQL—whichever fits best), secure, and well-documented so I can maintain it easily. A brief hand-off guide, plus any source files or app code, will be the final deliverable.
