Back In Stock with woocommerce

Hi there,

It is possible to implement Back in Stock with WooCommerce and Klaviyo using a combination of a custom catalog and API calls. WooCommerce’s standard catalog does not include inventory; as a result, back in stock cannot currently be implemented with the standard WooCommerce catalog. Note: the specifics of setting up a custom catalog for implementing back in stock are covered in our custom catalog documentation, which is not yet publicly facing. If you would like a copy of this information, shoot me a DM.

Once you’ve set up a custom catalog which includes stock for each product, you can make the following API calls to subscribe customers to Back in Stock.

Client-side

$.ajax({
    type: "POST",
    url: "https://a.klaviyo.com/onsite/components/back-in-stock/subscribe",
    data: {
        a: "ACCOUNT_ID",
        email: "EMAIL",
        variant: VARIANT_ID,
        product: PRODUCT_ID,  // Product must be present in Klaviyo catalog to record event.
        platform: "shopify",
        subscribe_for_newsletter: false,  // Optional with "g". Defaults to false if omitted.
        g: "LIST_ID",  // Optional with "subscribe_for_newsletter".
    },
    success: function(response){
        console.log(response)
    }
})

• a: KLAVIYO_PUBLIC_TOKEN
• email: the email address of the person (eg. a template tag like {{ email }})
• g: the ID of the list you want to subscribe them to in addition to the Back in Stock subscription
• variant: the variant ID of the product (sometimes the same as the product ID)
• product: the ID of the product
• platform: the platform from which the request is being sent (we currently accept "shopify", "bigcommerce", or "api")
• subscribe_for_newsletter: true if you want to subscribe them to a list in addition to the Back in Stock subscription (otherwise false)}

Server-side

The API endpoint can allow a platform of api (custom catalogs) or ‘shopify’.  NOTE: if you're using a custom catalog, you'll need to utilize the $inventory_quantity field inside of the custom catalog to track inventory for in/out of stock items

Example call:

curl 'https://a.klaviyo.com/api/v1/catalog/subscribe' --data 'a=AccountID&email=test@klaviyo.com&variant=5000149172256&platform=shopify'

Your POST request must include:

• a: Your public Klaviyo API Key (6 characters, can be retrieved from https://www.klaviyo.com/account#api-keys-tab)
• email: The email address entered by the subscriber (must be correctly formatted & valid)
• variant: The variant ID, for Shopify stores only.
• platform: shopify

Note: To subscribe a customer to a list as part of the Back In Stock workflow, you will need to make a separate, additional call to our existing List API: https://www.klaviyo.com/docs/api/lists

Happy to answer any followup questions.

Best,

Caroline
