Automatically parse ecommerce parameter from webhook

[juansebas0712]

Hi guys, could you please add support to parse ecommerce data from incoming webhook (shopify and woocommerce)?

facebook-tag/template.js

Line 447 in a9d6e33

let valueFromItems = 0;

I changed and testes this tweak and it works properly:
Added a new variable called "items" that picks either the items or ecommerce.items from event data:
let items = eventData.items || eventData.ecommerce.items;
then changed the reference within the addEcommerceData function.

function addEcommerceData(eventData, mappedData) {
let currencyFromItems = '';
let valueFromItems = 0;
let items = eventData.items || eventData.ecommerce.items;

if ( items && items[0]) {
mappedData.custom_data.contents = [];
mappedData.custom_data.content_type =
eventData['x-fb-cd-content_type'] || eventData.content_type || 'product';
currencyFromItems = items[0].currency;

if (!items[1]) {
  if (items[0].item_name)
    mappedData.custom_data.content_name = items[0].item_name;
  if (items[0].item_category)
    mappedData.custom_data.content_category =
      items[0].item_category;

  if (items[0].price) {
    mappedData.custom_data.value = items[0].quantity
      ? items[0].quantity * items[0].price
      : items[0].price;
  }
}

const itemIdKey = data.itemIdKey ? data.itemIdKey : 'item_id';
items.forEach((d, i) => {
  let content = {};
  if (d[itemIdKey]) content.id = d[itemIdKey];
  if (d.item_name) content.title = d.item_name;
  if (d.item_brand) content.brand = d.item_brand;
  if (d.quantity) content.quantity = d.quantity;
  if (d.item_category) content.category = d.item_category;

  if (d.price) {
    content.item_price = makeNumber(d.price);
    valueFromItems += d.quantity
      ? d.quantity * content.item_price
      : content.item_price;
  }

  mappedData.custom_data.contents.push(content);
});

}

if (eventData['x-ga-mp1-ev'])
mappedData.custom_data.value = eventData['x-ga-mp1-ev'];
else if (eventData['x-ga-mp1-tr'])
mappedData.custom_data.value = eventData['x-ga-mp1-tr'];
else if (eventData.value) mappedData.custom_data.value = eventData.value;

if (eventData.currency) mappedData.custom_data.currency = eventData.currency;
else if (currencyFromItems)
mappedData.custom_data.currency = currencyFromItems;

if (eventData.search_term)
mappedData.custom_data.search_string = eventData.search_term;

if (eventData.transaction_id)
mappedData.custom_data.order_id = eventData.transaction_id;

if (mappedData.event_name === 'Purchase') {
if (!mappedData.custom_data.currency)
mappedData.custom_data.currency = 'USD';
if (!mappedData.custom_data.value)
mappedData.custom_data.value = valueFromItems ? valueFromItems : 0;
}

return mappedData;
}

Thanks for this awesome resource.

Hi @juansebas0712, thank you for bringing this up. We'll discuss it internally.

In the meantime, you can create a Transformation that accomplishes the same results. This way, you won't need to unlink your template, and you'll continue to receive updates. Other tags will also benefit from this approach.

Something like this:
