Meta Pixel — Dakio developer docs

Dakio already sends the server side of Purchase, Lead and InitiateCheckout (Meta's Conversions API) for every store with a Pixel set up in Dakio. Send the browser side with the same event id and Meta counts each event once, with better matching than either side alone.

import { loadPixel, trackPixel, newEventId, productParams, purchaseParams } from '@dakio/sdk/pixel'

const store = await dakio.store.get()
loadPixel(store.tracking.metaPixelId)          // does nothing when the store has no Pixel

trackPixel('ViewContent', productParams(product), newEventId())
trackPixel('AddToCart', productParams(product, qty), newEventId())

Purchase, deduplicated

Make the id before checkout, pass it as eventId, and fire the browser event with it once the order is placed:

const eventId = newEventId('pur')
const result = await dakio.checkout.create({ ...input, eventId })
if (result.status === 'PLACED') trackPixel('Purchase', purchaseParams(quote), eventId)

Dakio's server event for that order carries the same eventId, so Meta merges the two.

Export	What it does
loadPixel(id)	Adds Meta's pixel script once and fires PageView
trackPixel(event, params, eventId?)	fbq('track', …) with eventID; a no-op on the server
newEventId(prefix?)	A unique id like pur_k3p9…
productParams(product, qty?)	{ content_ids, content_name, content_type, value, currency, num_items }
purchaseParams(quote)	The same, for a whole priced bag

Google Tag Manager: store.tracking.gtmContainerId holds the store's container id if it has one, and every trackPixel call also pushes dakio_<Event> (with the same params and eventId) to dataLayer.
