How to create Shopify Apps with Ruby On Rails?

To create the Shopify app, you need to follow these steps

1. Create a Shopify Partner account 

2. Once you create that, you will need to create a custom Shopify app within the partner dashboard

3. Setup URLs within the app. Here local machine URL like localhost will not work so you need ngrok or another tunneling software like ssh, localtunnel, and more.

• App URL: “https://{your domain}”

• Redirection URL: “https://{your_domain}/auth/shopify/callback”

4. Get the API key and API secret key from the app.

SSL certificate is required if you are using your own domain after deployment on the server. (Make sure you use https://)

Now let’s create Ruby On Rails application and integrate Shopify app gem within it for create Shopify apps

Create a new rails application with

Then open the Gemfile and add Shopify app gem into it

Then install the gem with a

  config.embedded_app = false

• scope means whatever permission you need from Shopify to get access data into Shopify apps. Make sure you can ask only that permission which you needed.

You can install this app on your store with URL which you have created with tunnel link(ngrok or other which you have used) after starting rails server with rails s

It will ask for shop_domain where you want to install this app like this. So enter your shop domain and install the app.

Now you can enjoy your Shopify app and play with that with different products, customers, orders, theme customization, etc.

During the installation of the app into your store, you can create some default webhooks as well which you needed in your app using Shopify API.

You just need to add this snippet into shopify_app.rb file

If you don’t want to create a default webhook while app installs, then you can use this code to create webhooks within code anywhere.
