Shopify - Sendlane

Send every Shopify event to Sendlane, server-side

Q: What happens if a contact doesn’t exist in Sendlane?

Upstack only sends events for contacts that already exist in Sendlane. If the visitor’s email isn’t found in your account, the event is skipped, which keeps your account clean and targets only real subscribers.

Q: Will I get duplicate events if I keep Sendlane’s native Shopify integration?

Possibly. If both Upstack and Sendlane’s native integration track the same event types, Sendlane may record both, so disable the corresponding events in the native integration for any event types Upstack sends.

Q: Which events does Sendlane receive?

ViewContent as product-viewed-upstackified, AddToCart as added-to-cart-upstackified, InitiateCheckout as checkout-started-upstackified and Purchase as order-placed-upstackified. Orders reach Upstack directly from Shopify, even when the browser pixel is blocked.

Q: Which customer parameters are sent to Sendlane?

Upstack looks up each contact in Sendlane by email or Sendlane contact ID, and sends the event only if the contact already exists.

Q: How do I check that Shopify events are reaching Sendlane?

Trigger a test action on your store, such as adding a product to cart, and check the contact’s activity feed in Sendlane. Events are sent only for contacts that already exist in Sendlane.

Q: Do I need a developer to connect Shopify to Sendlane?

No. Shopify connects as an app install with no theme edits, and most brands are live in under 20 minutes. Headless storefronts add the Upstack Pixel script instead of the theme app extension.

Each event is resolved to a person against a 750M+ device graph before it reaches Sendlane, so flows trigger on a known profile rather than an anonymous session.

How it flows

How a Shopify event reaches Sendlane. Captured on the server, resolved to a person, then sent.

01 Capture

Captured from Shopify

One Upstack app setup that captures Shopify storefront and checkout events with the Upstack Pixel, records every order directly from Shopify, and forwards both to every tool you spend on.

See the Shopify integration

ShopifyWhat it sends

order_idShopify order and checkout token
email / phonecustomer contact from checkout
customer_idShopify customer record, if they have one
line_itemsproducts, variants and quantities
total / subtotal / discountorder economics

02 Understand

Resolved to one person before it leaves

Every Shopify event is matched against a 750M+ device graph, so a phone browse and a desktop checkout resolve to one customer rather than two strangers.

How resolution works

Resolved before it is sent

IdentityMatched against a 750M+ device graph, so a phone browse and a desktop checkout resolve to one customer.
customer_typeNew or returning, resolved before send.
DeduplicationOne order produces one event, so a single purchase cannot trigger the same flow twice.
Bot and fraud filteringAutomated traffic never becomes a profile, so list quality and deliverability are not paying for it.

Messaging mistakes are expensive and public. These controls exist so a flow never fires against a profile that should not have received it.

03 Activate

Which events reach Sendlane

Each Upstack event is mapped to the Sendlane event below before it is sent.

Upstack event	Sent to Sendlane as	Key data on the event
Product view	product-viewed-upstackified	product_id, product_name, product_img_url, variant_id
Add to cart	added-to-cart-upstackified	line_items, subtotal, total, currency
Checkout	checkout-started-upstackified	checkout_id, line_items, subtotal, total, currency
Purchase	order-placed-upstackified	order_id, line_items, total, currency, discounts

Upstack looks up each contact in Sendlane by email or Sendlane contact ID, and sends the event only if the contact already exists.

The catch

Shopify only knows a customer at checkout.

Everything before that (the browse, the add to cart, the return visit four days later) is anonymous unless something resolves it. That is the gap the flows fall into, not a problem with the flows.

Where to check in SendlaneSending you can audit

Sendlane the contact record

where the event should appear against one person rather than creating a second contact.

What changes

What changes when Shopify feeds Sendlane. Two gains on the Sendlane side, two on the Shopify side.

Sendlane

Server-side delivery

Upstack sends events to Sendlane from its servers only, so ad blockers and browser privacy settings can’t block delivery.

Sendlane

Identity-resolved events

Events sent to Sendlane carry the resolved customer whenever Upstack can identify one, matched against a 750M+ device graph.

Shopify

Orders recorded from Shopify itself

Purchases also reach Upstack directly from Shopify, about 10 minutes after the order, so an order still counts when an ad blocker stopped the pixel or the shopper closed the page.

Shopify

Recognize returning customers

Shopify customer IDs, emails and phones are matched against the graph, so repeat buyers are identified across devices.

Setup

Live in under 20 minutes.

App install, no theme edits and no developer. You need a Sendlane account where you can generate an API Access Token and create a Custom Integration and owner or staff access to Shopify.

03

Check the contact’s activity feed
