Shopify: Back in Stock via API not working

Question

Hello, I am new to Klaviyo and I would like to make a back in stock API call out of my Shopify store, like explained here. I do not understand the error: is my products do not have a variant, only a product ID. And maybe I miss understood the concept of a relationship. I thought I am creating one by assigning a product to a profile by this query. Maybe someone can help me.

# URL
url = "https://a.klaviyo.com/client/back-in-stock-subscriptions/?company_id=myID"

# Body
body = {
  "data": {
    "type": "back-in-stock-subscription",
    "attributes": {
      "profile": {
        "data": {
            "type": "profile",
            "attributes": {
                "email": "email@mail.com"
            }
        }
      },
      "channels": ["EMAIL"]
    },
    "relationships": {
      "product": {
        "data": {
          "type": "catalog-variant",
          "id": "$shopify:::$default:::productID"
        }
      }
    }
  }
}

I get the error code:

Response Text: {"errors":[{"id":"dfae79b0-0dd5-46e4-9b3c-7906e4ed4280","status":404,"code":"variant_not_found","title":"The variant in your relationship payload does not exist","detail":"The variant in your relationship payload does not exist","source":{"pointer":"/data/relationships/variant/data/id"},"links":{},"meta":{}}]}

Hey@ITgirl, the error you’re getting is because you’re using the product ID instead of the variant ID. I believe even in the case where you don’t have multiple variants configured for Shopify there is a default variant ID that can be obtained.We have a recommended way to install Back in Stock using a JS widget detailed on our Help Center here:https://help.klaviyo.com/hc/en-us/articles/360001895651.This way, Klaviyo.js handles some of the heavy lifting around determining the variant ID, whether the item is in stock or out of stock and what the variant ID is.If you’re trying to wire this up yourself using the client API directly….In liquid, you mightbe able to do something like:https://stackoverflow.com/questions/45740173/how-to-get-the-current-products-variant-idIn custom JS, the shopify product page has a hidden input where the name=”id” that would contain the relevant product variant ID. Something like the following may work hereconst variantId = document.querySelector('[name="id"]').value
