You can enhance customer experience by integrating Regios Automatic Discounts deeply with your theme.

To do this, use the DOPP (discount on product page) API. It's a combination of event listeners (which you can fire to trigger updates to our app blocks), and public objects/functions (which you can use to handle the results of calculations yourself).

Public API documentation

You can paste this TypeScript definition into your project as a .d.ts file.

Public API Example

const {salePrice, regularPrice} = await window.RegiosDOPP.api.v0.productPage.calculateDiscountedPrices();
const discountAmount = regularPrice.amount - salePrice.amount;
console.log('Your discounted price: ' + salePrice.formatted);
console.log('Discount amount: ' + discountAmount);

You can also pass a specific variant ID, and/or quantity:

const {salePrice, regularPrice} = await window.RegiosDOPP.api.v0.productPage.calculateDiscountedPrices({
  variantId: 0123456789,
  quantity: 1234,
});

You can also get the discount description/badge content, and CSS:

const {description, badge} = await window.RegiosDOPP.api.v0.productPage.calculateDiscountedPrices();
document.querySelector('.discount-description').innerHTML = description.html;
document.querySelector('.discount-description').style.cssText = description.css;
document.querySelector('.badge').innerHTML = badge.html;

Events

Our app listens to the following events on the window:

Variant Change Event

In case your theme has complex behavior about selecting variants on the product page, you can manually trigger a discount calculation by firing a regios-dopp:variant-change event.

Example

window.dispatchEvent(new CustomEvent("regios-dopp:variant-change", {
    detail: {
        selectedVariant: {
            id: 0123456789,
            price: 3000,
        },
        quantity: 1,
    }
}))

Parameters

All parameters are optional unless stated otherwise.
selectedVariant.id: Required. A product variant's numerical ID.
selectedVariant.price: The variant's price, in cents. You can optionally provide this to change the number we base discount calculations on.
quantity: The quantity of the product to calculate the discount based on. Useful for volume discounts.
