Data direction: This is a destination — Upstack sends event and conversion data out to this platform via server-side APIs.
Loops is connected through Upstack Flows, the product that handles event delivery to marketing automation platforms. Upstack identifies visitors that standard tracking misses — turning anonymous browse and cart abandonment sessions into actionable Loops contacts with email addresses attached. This means more automated email workflows fire, more transactional messages reach the right customers, and you recover revenue that would otherwise be invisible.

​
How It Works

When a visitor takes an action on your store, Upstack:
  1. Captures the event through the Upstack Pixel and matches it to a known visitor profile using Upstack’s identity resolution.
  2. If the visitor is identified (email available), enriches the event with the contact’s email and any other known properties.
  3. Sends the event to Loops using your Loops API key as a trackable event that can trigger automations.
  4. Optionally creates or updates the contact in Loops so it can be segmented and used in campaigns.
The result: email automations fire for visitors that standard tracking misses.

FAQ

Loops is an email marketing and automation platform designed for modern SaaS and e-commerce businesses. It allows you to create automated email sequences triggered by user behavior, send transactional emails, and manage marketing campaigns — all through a simple API-first interface.
Standard Shopify integrations only see visitors that Shopify has identified — typically logged-in customers or shoppers who have entered an email at checkout. Upstack’s identity resolution matches anonymous sessions to known customer profiles using cookies, click IDs, and cross-session behavioral data, then sends those events to Loops with the contact’s email attached. This lets your automated workflows fire for many more visitors.
The Loops API key must have permission to write events and contacts. When creating your API key in Loops, ensure it has the scopes required to send events and create or update contacts.
Once the destination is active, events typically appear in Loops within a few minutes. You can verify by triggering a test action on your store (such as adding a product to cart) and checking the Events section in Loops.
Yes. Any event tracked by the Upstack Pixel can be configured to forward to Loops. Contact support if you need to send custom events beyond the standard e-commerce events.

Troubleshooting

If events show in the Upstack Live Event Stream but aren’t arriving in Loops:Steps to fix:
  1. Confirm the Loops destination shows Active (green) in the Upstack dashboard
  2. Verify your API key is valid — try regenerating it in Loops if you’re unsure
  3. Check the Events section in Loops — events may appear under a different name than expected
  4. If the destination status is red, disconnect and reconnect with a fresh API key
If events are arriving but contacts aren’t being created:Steps to fix:
  1. Ensure the API key has permission to create contacts
  2. Verify that Upstack has resolved an email address for the visitor — anonymous events without an email won’t create contacts
  3. Check if the contact already exists in Loops under a different email or identifier
