Getting started with Shopify App Bridge

First, create a development store and an app.

By default, new apps are embedded in the Shopify admin. If you need to turn on embedding for an app, follow these steps:

1. From your Partner Dashboard, click Apps.
2. Click the name of your app.
3. From the app overview screen, click App setup.
4. In the Embedded app section, click Manage.
5. In the Embed your app in Shopify admin section, click Enable.

After you've enabled embedding for an app, Shopify attempts to load your app inside an iframe in the admin.

To embed your app in Shopify POS:

1. From your Partner Dashboard, click Apps.
2. Click the name of your app.
3. From the app overview screen, click App setup.
4. In the Embedded app section, click Manage.
5. In the Embed your app in Shopify POS section, click Enable.

After you've enabled embedding for an app, your app appears in the Shopify POS mobile app.

The Shopify admin uses HTTPS for all pages. Embedded applications also need to use HTTPS.

Failure to use SSL when running an embedded app will cause errors in web browsers, due to mixed content restrictions.

The Content Security Policy frame-ancestors directive controls where the app can be framed. You must ensure your app is only frameable by the authenticated shop domain and the admin domain to avoid clickjacking attacks.

You can do this with the Content Security Policy frame-ancestors directive:

Shopify App Bridge is available as a JavaScript module on npm. To install it in your app (to use with bundlers or build systems like webpack), you can use npm or yarn:

Shopify App Bridge can also be included directly on a page with a <script> tag pointing to a CDN-hosted copy of the library. Unpkg is an example of a CDN that hosts npm modules.

Since embedded applications are loaded inside an iframe, the initial OAuth redirect to Shopify must occur at the parent level, escaped from the iframe. Shopify returns the X-Frame-Options: DENY header and prevents any Shopify admin pages from being loaded inside an iframe. Shopify App Bridge provides an action that can be used to perform a redirect within the parent window.

This means that where the OAuth process would normally begin with redirecting the merchant to the authorization prompt, it should instead return a page containing a script which escapes the frame.

At the end of the OAuth flow, the user is redirected to the redirectUri you provided. We recommend that you let App Bridge redirect the user back to Shopify. As part of the initialization process, App Bridge redirects the user, if necessary, to ensure your app is embedded in the Shopify admin.

Once you’ve added Shopify App Bridge to your app, you need to initialize it by passing in your API key and the shop name.

The script detects if your app was loaded inside an iframe. If it wasn't, then the script creates a redirection back into the relative embedded URL in the Shopify admin. You can disable this functionality by passing forceRedirect: false as a configuration option.

On every page of your app, you should define the behavior of the Shopify TitleBar in relation to your application. For single-page apps (SPAs) you can update the title bar based on your app state. The following example script updates the TitleBar.

Now that you've initialized your app, you can use any Shopify App Bridge actions.
