Introduction

Shopify Custom apps

You can use custom apps to add features to your Shopify admin, access your store's data directly using Shopify's APIs, or extend your online store to other platforms using the Storefront API.

Enable custom app development from the Shopify admin

Before you can create a custom app for your store, you need to enable custom app development. You need to be the store owner or a staff member with the Enable app development permission to enable custom app development.

Create and install a custom app

After you have enabled custom app development, you can create and install a custom app in your Shopify admin. You need to set API scopes to determine which parts of your store the custom app can access. After the app is installed, you'll receive access tokens that the app uses to access information from your store using Shopify's APIs.

Create the app

1. From your Shopify admin, click Settings > Apps and sales channels.

2. Click Develop apps.

3. Click Create a custom app.
   Reference URL: https://admin.shopify.com/store/testextendse/settings/apps/development
   
   
   
   
   

4. In the modal window, enter the App name and select an App developer. The app developer can be the store owner, or any staff or collaborator account with the Develop apps permission.
   
   
   
   

5. Click Create app.
   

Select API scopes

• Click Select scopes.

• In the Admin API access scopes section, select the API scopes that you to assign to the app.
  
  
  
  
  
  
  
  

• Click Save.
  
  

Install the app and get the API access tokens

After you've set API scopes for your app, you can install the app. You'll get your API access tokens after you install. Depending on what API scopes you assigned to the app, you'll get an Admin API access token, a Storefront API access token, or both.

1. Click Install app.
2. In the modal window, click Install app.
3. Get the access token:

• If you selected Admin API scopes for the app, then go to the Admin API access token section and click Reveal token once.

After revealing the full access token once, this page displays only the last 4 digits of the access token for reference.

Get the API credentials for a custom app

You can check the Storefront access token, the API key, and the API secret for a custom app from the app's API credentials page. You can also check the Admin API access token, but after revealing it once, you can only check the last four digits of the token.

• From your Shopify admin, click Settings > Apps and sales channels.

• Click Develop apps.

• Click the name of the app that you want the credentials for.

• Click API credentials
