Recreate shopify webhooks

When developing custom Shopify apps, I usually use ngrok as a reverse proxy for webhooks integration. Since I always use a free service plan from Ngrok, then the URL address always changes. Here is the sample generated Ngrok URL when running

ngrok http 3000

Generated endpoint
https://73d3-2001-448a-3032-c93e-bc56-f800-e58d-8a98.ngrok-free.app

When we hit ctrl+c and rerun the command, we will get a different new URL.

So what I did was just change the .env file of my Rails project, go to console, and recreate Shopify webhooks.

bundle exec rails c

Shop.first.recreate_webhooks!

And here is the code for recreate_webhooks!

# app/models/shop.rb

  def recreate_webhooks!
    ShopifyAPI::Webhook.all.each do |webhook|
      webhook.destroy
    end

    ShopifyApp.configuration.webhooks.each do |item|
      webhook = ShopifyAPI::Webhook.new(item)
      if webhook.save
        puts "webhook #{item} created."
      else
        puts "webhook #{item} failed."
      end
    end
  end

So every time you need to regenerate webhooks, you can just run this method from rails console.
