I want to mange this disocunt from App database.

Hello @devopskecg, 

What you’re describing is definitely doable, but it does involve building a custom solution that touches both the Shopify Admin and the storefront. Here’s a high-level breakdown of one approach:

1. Build an Embedded Admin Form:

   • Use Shopify App Bridge and Polaris to create an embedded app interface within Shopify Admin.
   • In your form, let merchants select products, variants, quantities, discount percentages, etc.
   • Save these discount rules to your own app database.

2. Apply Auto Discounts on the Storefront:

   • Once your discount rules are stored, you need a way to automatically apply them in the cart/checkout.
   • If you’re on Shopify Plus or using Shopify Functions (via discount extensions), you can implement a discount function that reads your rules and applies the appropriate discount.
   • Alternatively, you might inject a discount code (if auto-application isn’t supported) via custom scripts or an app proxy that calls your backend to fetch the right discount.

3. Integration & Testing:

   • Make sure your embedded form is well integrated (using Shopify’s recommended UI frameworks) so that merchants can easily manage discounts.
   • Test thoroughly to ensure that the auto discount logic correctly applies the discount based on the cart contents.

This approach lets you manage discount rules from your app’s admin side while seamlessly applying them during checkout, without relying on manual discount codes.

Hope that gives you a clear roadmap! Let me know if you have more questions or need further details on any step.
