Deploy Shopify App: “Shopify Doesn’t Host Your App” — The Journey to Getting Your App Live

You’ve just finished coding a Shopify App, shopify app dev runs smoothly on local, everything works. And then you ask yourself: “How do I deploy this to Shopify?”

This is where many developers start getting confused. Because the truth is: Shopify does not host your application. Shopify is not a PaaS platform like Heroku or Vercel where you push code and it just runs. Shopify only manages your app at a logical level — scopes, permissions, app info, OAuth flow, billing, … — while the “actually running” part is your responsibility.

Think of Shopify as the management office of a shopping mall. They manage store signs, lease agreements, access cards, and security policies. But they don’t build the store for you. You have to build the physical store yourself (deploy your app to the cloud), then go to the management office to register (create a logical app on Shopify) and point it to your store’s address.

So, “deploying a Shopify App” is actually two separate tasks:

1. Deploy the physical app to your cloud provider.
2. Create the logical app on Shopify and point it to that physical app.

This article will guide you through each step, along with mistakes I encountered along the way.

0. Prerequisites

Before you begin, make sure you have:

• Working app code on local — tested with shopify app dev
• Shopify Partners account — register at partners.shopify.com 
• Cloud provider ready — AWS (App Runner, ECS, EC2), Railway, Fly.io, Render, or any platform you’re familiar with
• Development Store — to test the app after deployment
• Shopify CLI — @shopify/cli installed
• shopify.app.toml file — your app’s config file (you can have multiple files for different environments, e.g., shopify.app.staging.toml, shopify.app.production.toml)

1. Deploy the Application to the Cloud

This is the first and most important step: get your application running on the cloud.

Shopify communicates with your app via HTTP/HTTPS. So your application needs to:

• Have a public URL accessible from the internet
• Serve HTTPS (mandatory)
• Pass a health check — at minimum, the root endpoint should return 200 OK

You can deploy to any cloud provider. Some popular options:

• AWS App Runner / ECS — suitable if you’re already familiar with the AWS ecosystem
• Railway / Render — simple, great for prototypes and side projects
• Fly.io — good for apps that need low latency across multiple regions

After deploying, verify by making a test call:

curl -I https://your-app.your-cloud.com/

Note: If your root endpoint returns a redirect (301/302), Shopify may not recognize the app. Make sure at least one endpoint returns 200 OK directly.

Think of this step as “finishing construction and turning the lights on” — you don’t need to know who the customers are yet, but the store needs to be open for business.

2. Create the Logical App on Shopify

Now that the physical store is ready, you need to go to the “management office” to register.

Navigate to:

https://dev.shopify.com/dashboard/<org-id>/apps

Here, click “Create app” and fill in the basic information for your app (app name, description, …).

At this point, Shopify knows your app exists — like having a business license. However, Shopify doesn’t yet know where your store is located. The URL pointing will be done through the config file in step 5.

dev.shopify.com vs partners.shopify.com

This is a confusing point for many people:

• dev.shopify.com — the new dashboard where you create and manage apps, view API credentials
• partners.shopify.com — the older dashboard, but still necessary for certain features like App Distribution and managing restricted scopes

You’ll need to use both during the deployment process.

3. Configure Restricted Scopes and App Distribution

This step isn’t always necessary, but if your app falls into one of the following cases, it’s mandatory:

• App uses restricted scopes like write_orders, read_all_orders, write_customers, …
• App has extensions that use network access (e.g., a Checkout UI Extension that calls external APIs)

What Are Restricted Scopes?

Shopify categorizes API scopes into two groups:

• Standard scopes
• Restricted scopes

How to Enable

1. Go to partners.shopify.com 
2. Select your app → Distribution
3. Enable distribution and submit a request for the restricted scopes

Note: The review process from Shopify can take some time. If you skip this step and your app needs restricted scopes, the shopify app deploy command in step 5 will fail with a permission error — and the error message may not be very clear.

4. Get API Credentials and Update the Cloud App

Go back to dev.shopify.com, navigate to the Settings section of the app you just created, and you’ll find:

• Client ID
• Client Secret

These are the “keys” that allow your app to authenticate and communicate with Shopify. Update these values in your cloud application’s environment variables:

SHOPIFY_API_KEY=your_client_id_here
SHOPIFY_API_SECRET=your_client_secret_here
SCOPES=write_products,read_orders
HOST=https://your-app.your-cloud.com

Then redeploy the application for the new variables to take effect.

Security tip: Don’t store the API Secret as plain text in your cloud console’s environment variables. Use a secrets manager instead. If you’re on AWS, you can refer to the article Guide to Managing Environment Variables with AWS Secrets Manager for App Runner.

After redeploying, check the health check again to make sure the app is still working:

curl -I https://your-app.your-cloud.com/

5. Sync Configuration with Shopify CLI

This is the step that ties everything together. The shopify app deploy command reads your local config file and syncs it to Shopify — including the app URL, redirect URLs, scopes, and extension configurations.

shopify app deploy --config production

What Does the shopify.app.toml File Contain?

This is the central configuration file of a Shopify App, defining everything Shopify needs to know:

name = "My Awesome App"
client_id = "your_client_id"
application_url = "https://your-app.your-cloud.com"
 
[auth]
redirect_urls = [
  "https://your-app.your-cloud.com/auth/callback"
]
 
[access_scopes]
scopes = "write_products,read_orders"

After running shopify app deploy, Shopify will know exactly where your app is running, what permissions it needs, and where to redirect after OAuth.

Important: Step 3 (restricted scopes approval) must be completed before running this command. If not yet approved, the deploy will fail.

6. Install the App on a Dev Store for Testing

Everything is ready. Now install the app on a Development Store to verify the entire flow:

1. Go to the app in the Shopify dashboard → get the install link
2. Open the link on the Dev Store → complete the OAuth flow
3. The app will appear in the Dev Store’s admin

Testing Checklist

After installation, verify the following:

• OAuth flow completes without errors — app is installed successfully
• App loads correctly in Shopify Admin — no blank page or CORS errors
• API calls work — try basic operations (read products, create draft order, …)
• Webhooks are received (if the app registered any) — check logs on the cloud
• App Extensions render correctly (if applicable) — check on the storefront or checkout

If the OAuth flow has a redirect error, check whether the redirect_urls in the toml file exactly match the URL on the cloud (including the https:// protocol and trailing path).

Process Summary

Always remember the mental model: Shopify manages identity, you manage infrastructure. “Deploying a Shopify App” doesn’t mean pushing code to Shopify — it means registering your app with Shopify and pointing to where it’s actually running.

Common Mistakes

Here are some errors you may encounter during deployment:

Health check failure

• App returns a redirect (301/302) instead of 200 at the root URL
• SSL certificate not configured correctly (Shopify requires HTTPS)
• App hasn’t finished starting when Shopify performs the health check (cold start takes too long)

Permission errors when running shopify app deploy

• Restricted scopes haven’t been approved on partners.shopify.com
• App distribution hasn’t been enabled
• Network access for extensions hasn’t been turned on

OAuth redirect errors

• redirect_urls in the toml file don’t match the actual URL on the cloud
• Missing or wrong protocol (http vs https)
• Wrong client_id in the config file — especially common when you have multiple environments

App shows a blank page after installation

• SHOPIFY_API_KEY or SHOPIFY_API_SECRET haven’t been updated on the cloud
• Frontend app’s HOST isn’t configured correctly — causing the iframe to fail to load
• CORS policy blocking requests from the Shopify Admin domain
