Product Feed

In Klaviyo, product feeds are added via Catalog Sources. This view is hidden for custom API plugins like this one, but still accessible and usable here: https://www.klaviyo.com/catalog/sources. Once you've created your JSON feed, add it to a new Catalog Source to make the products within it available to your Klaviyo emails. Confirm your product feed is working on the Catalog page.

JSON Feed

• Install Craft's Element API plugin
• Configure Element API to export a product feed, for example:

<?php

use craft\commerce\elements\Product;
use craft\helpers\UrlHelper;

return [
    'endpoints' => [
        'products.json' => function() {
            return [
                'elementType' => Product::class,
                'transformer' => function(Product $entry) {
                    $variant = $entry->defaultVariant;
                    return [
                        'id' => $entry->id,
                        'title' => $entry->title,
                        'sku' => $variant->sku,
                        'url' => UrlHelper::url("/products/{$entry->id}"),
                    ];
                },
                'pretty' => true,
                'paginate' => false,
            ];
        },
    ]
];

• Navigate to <your-site-url>/products.json
