Stripe - Sendlane

Send events from your Stripe-billed app to Sendlane

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: 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.

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 Stripe 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: How long does it take to connect Stripe to Sendlane?

Most brands are live in under 20 minutes. Once Stripe events reach Upstack, every destination receives the same resolved events, Sendlane included.

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 Stripe event reaches Sendlane. Sent from your app, resolved to a person, then forwarded.

01 Capture

Captured from Stripe

For apps that bill through Stripe, send payment and subscription events to Upstack with the Upstack Pixel and JavaScript SDK, resolved to a customer before they reach the tools you spend on.

See the Stripe integration

StripeWhat it sends

subscription_initial_purchaseyou fire it for the first subscription order
subscription_recurring_purchaseon invoice.paid for an existing subscription
payment_succeededmaps to invoice.paid or charge.succeeded
payment_refundedmaps to charge.refunded
amount / currencyamount in cents, with invoiceId and subscriptionId

02 Understand

Resolved to one person before it leaves

Every Stripe 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.

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

Stripe sees the payment, not the browse.

A customer who abandoned twice before paying looks like a first-time buyer with no history, so flows built on Stripe data alone have nothing to personalize against.

What changes

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

Stripe

Subscription purchases as events

Fire subscription_initial_purchase for the first order and subscription_recurring_purchase each time a renewal is paid, so first orders and renewals are reported separately.

Stripe

Payments and refunds

payment_succeeded, payment_failed and payment_refunded each map to a Stripe event (invoice.paid or charge.succeeded, invoice.payment_failed, charge.refunded), so money events reach Upstack when your app fires them.

Setup

Live in under 20 minutes.

You need a Sendlane account where you can generate an API Access Token and create a Custom Integration.

01

Install the Upstack Pixel and SDK

Add the Upstack Pixel to your app, then fire the subscription and payment events with the JavaScript SDK when Stripe reports them, such as subscription_recurring_purchase when invoice.paid fires for an existing subscription.
02

Add the Sendlane destination

Under Destinations, add Sendlane with two credentials: an API Access Token from Settings, API, and the Integration Token from a new Custom Integration under Integrations in Sendlane.
03

Check the contact’s activity feed

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.
