Shopify agentic commerce starts with accurate product and policy information and a working path for the actions you support. Agents can use storefront pages, structured responses and configured integrations to evaluate an offer.

Rebilder’s Shopify app-proxy adapter offers a Markdown response under a store subpath. This guide explains that developer integration and how to verify it.

## Prepare the catalog and policy sources

Check variant names, prices, stock and delivery terms for the products you want assistants to evaluate. Include the return policy and any conditions that change the offer. Keep these fields connected to the systems the merchant already maintains.

Read a product page as a direct response and in a browser. The goal is a complete answer in the relevant client path. HTML can contain that answer; a compact Markdown view is an additional interface.

## How the app-proxy path works

A Shopify app proxy forwards requests from a configured store subpath to an app handler. Rebilder’s adapter uses that path to resolve the business source and return its configured representation. The customer’s normal storefront remains a separate route.

Use the [Shopify adapter reference](/docs/adapters/shopify) for current configuration. The developer adapter and the managed app installation are distinct paths; choose the integration offered for your account and platform setup.

## Configure the handler

- Set the app-proxy path and destination for the handler.
- Provide the required secret through the deployment environment.
- Connect the gateway configuration to product, policy and catalog sources.
- Deploy the handler and test a real source URL.

app/apps/rebilder/[[...path]]/route.ts

```ts
import { createShopifyAppProxyHandler } from '@rebilder/gateway/shopify'
import { gatewayConfig } from '@/lib/gateway-config'

export const GET = createShopifyAppProxyHandler(gatewayConfig, {
  sharedSecret: process.env.SHOPIFY_APP_SECRET!,
  pathPrefix: '/apps/rebilder',
})
```

## Verify the responses

Two fetches, two audiences

```bash
# Agent view: expect text/markdown and x-rebilder-path: markdown
curl -si -H 'Accept: text/markdown' \
  https://your-shop.myshopify.com/apps/rebilder/products/trail-pack

# Non-agent view of the same subpath: expect 404 {"error":"no_source"}
curl -si https://your-shop.myshopify.com/apps/rebilder/products/trail-pack
```

Confirm status, content type and the actual buying facts. Test a known product and a path with no matching source. Check the corresponding normal storefront page too.

If reporting is connected, inspect the resulting event in the Console. A response comparison shows the data served by this route; it is not proof of how every assistant used that information.

## Keep requests and offers under control

The adapter verifies forwarded proxy requests using the configured secret. Follow the current adapter reference for verification and error behavior. Keep private operations behind their own authorization rather than inferring authority from a public URL or claimed client name.

Equivalent representations of an offer should agree. If the business has a separate negotiated or restricted offer, its conditions and access need to be explicit.

## Add capabilities around the business workflow

Use reported requests to identify missing product details or useful operations. A catalog lookup, policy answer and checkout handoff solve different tasks. Configure and verify each operation against its source system.

The same data can support a generated llms.txt and other gateway adapters. Review source freshness and integration behavior as the store changes.

## How do I prepare for Shopify agentic commerce?

Keep catalog and policy information current, inspect the relevant response paths and connect supported operations.

## What does the app proxy do?

It forwards a configured storefront subpath to your app handler, which can return the source-backed response.

## Do I need to change my theme?

The app-proxy integration uses its own path. Follow the setup for the integration you choose and verify the normal storefront remains correct.

## Does the adapter complete every checkout?

The adapter supplies its documented operations. Verify the separate transaction and payment flow required for the purchase.

## How should I measure it?

Use connected request reporting and actual order records, keeping response activity distinct from completed purchases.
