A Shopify product inquiry app is essential for stores where customers have pre-sale questions before purchasing a product. By default, Shopify does not provide a native product inquiry system.

In this blog, we will learn how to build a Shopify product inquiry app using React Router, including storefront integration and admin management.

What We Are Going to Build

• Product page inquiry form
• Storefront to backend communication using App Proxy
• Admin panel to manage inquiries
• Admin response system
• Product linking using GraphQL

Product Page Inquiry Form (Frontend)

We added a custom inquiry form on the product page with the following fields:

• Name
• Email
• Phone number
• Message

Key Points:

• Uses App Proxy to submit form data
• Avoids exposing API credentials
• Works seamlessly inside Shopify theme

Create Shopify App Using React Router

Shopify now supports building apps using React Router (Remix-based architecture).

Why React Router?

• Server-side rendering
• Built-in loaders/actions
• Better performance

Inquiry Dashboard & Analytics

The app includes a dedicated dashboard that gives a quick overview of total inquiries, recent activity, and top-performing products. It helps merchants track customer interest and manage responses more efficiently.

Manage Inquiries (Admin Panel)

This screen shows all customer inquiries.

Features:

• List of inquiries
• Product association
• Status (Active/Inactive)
• Search & filter

Implementation:

• Data fetched using loader()
• Polaris DataTable used for UI

Create Inquiry (Admin Side)

Admin can manually create an inquiry.

// Code Example:
export async function action({ request }) {
  	const formData = await request.formData();
  	// validate data
  	// store in database
}

Edit Inquiry & Respond

Admin can:

• View customer message
• Add response
• Toggle frontend visibility

Fetch Products Using Admin GraphQL API

We use Shopify Admin GraphQL API to fetch products.

const response = await admin.graphql(`
  query {
    products(first: 10) {
      edges {
        node {
          id
          title
        }
      }
    }
  }
`);

Benefits:

• Faster than REST
• Fetch only required fields
• Better performance

Validation Logic (Reusable)

Create a utility file for validation:

export function validatePhone(phone) {
    // custom logic
}

Email Notification Templates (Admin & Customer)

To make the app more flexible and production-ready, I also implemented a custom Email Notification Template system inside the admin panel. This allows store owners to fully customize email content sent during inquiry workflows without changing code.

Key capabilities:

• Separate templates for:
  • Admin (New Inquiry Alert)
  • Customer (Reply Notification)
• Dynamic placeholders support:
  • {{customer_name}}
  • {{customer_email}}
  • {{product_title}}
  • {{message}}
  • {{admin_url}}
• HTML-based editor for rich email formatting
• Real-time variable replacement at send time

This approach ensures that merchants can control communication style, branding, and messaging directly from the app interface.

Conclusion

This Shopify Product Inquiry App demonstrates:

• Full-stack Shopify app development
• Real-world use case implementation
• Clean architecture using React Router

This approach is highly useful for:

• B2B stores
• Custom products
• Lead generation
