Shopify Custom App - Distribution Links

[asad-tech-dev]

Overview

I have configured the shopify_app gem and maintained the shopify_app initializer. You can see the code block below, and it is working fine on the production site.

# config/initializers/shopify_app.rb

ShopifyApp.configure do |config|
  config.application_name = ENV['APP_NAME']
  config.api_key = ENV['API_KEY']
  config.secret = ENV['SECRET_KEY']
  config.scope = 'read_products, write_products'
  config.embedded_app = true
  config.reauth_on_access_scope_changes = true
  config.after_authenticate_job = false
  config.shop_session_repository = 'Shop'
  config.allow_jwt_authentication = true
  config.api_version = '2023-10'
end

I have now changed the entire UI in my application and want to offer the new version to select clients for beta testing. In the Shopify documentation, I found that we can create Custom Apps and manage distribution links for merchants, where we define the user's store and provide them with a link to test the app in real-time.
https://shopify.dev/docs/apps/launch/distribution

To handle this, I want to configure the api_key, secret, and application_name at runtime, so the configuration adjusts dynamically when detecting that it is a beta version of the application.

My goal is to define the new configurations in the controller and call the method using before_action.

Please guide me how can I achieve this task.

# app/controllers/authenticated_controller.rb

class AuthenticatedController < ApplicationController
  before_action :set_shopify_keys

  def set_shopify_keys
    ShopifyApp.configure do |config|
      config.application_name = 'New App Name'
      config.api_key = 'new-app-api-key'
      config.secret = 'new-app-secret'
      config.scope = 'read_products, write_products'
      config.embedded_app = true
      config.reauth_on_access_scope_changes = true
      config.after_authenticate_job = false
      config.shop_session_repository = 'Shop'
      config.allow_jwt_authentication = true
      config.api_version = '2023-10'
    end
  end
end
