Shopify Purchase Event Not Tracking? Here’s What’s Really Happening
If your Shopify purchase event not tracking properly inside Meta Events Manager, your ad campaigns cannot optimize for conversions. That means higher cost per purchase, poor learning phase results, and wasted ad spend.
In 2026, this is one of the most common tracking issues Shopify store owners face. Sometimes the purchase event doesn’t fire at all. Sometimes it fires twice. And sometimes Shopify shows the sale, but Meta doesn’t register the conversion.
The good news? This issue is almost always fixable.
In this step-by-step guide, you’ll learn how to properly diagnose and fix Shopify purchase tracking issues, including duplicate events, thank you page problems, Pixel ID errors, and browser vs Conversions API conflicts.
Let’s Understand in details How to Fix Meta Pixel Tracking on Shopify 2026: Complete Troubleshooting & Step-by-Step Guide.
Why Shopify Purchase Event Tracking Breaks
Before jumping into fixes, you need to understand why this happens.
The Shopify purchase event not tracking problem usually occurs because of:
- Incorrect Meta Pixel ID connected
- Duplicate pixel installation
- Manual code conflicts
- Thank You page script errors
- Browser and Conversions API deduplication issues
If even one of these is misconfigured, Meta cannot attribute purchases correctly.
Step 1: Check If the Purchase Event Is Actually Firing
Use Meta Events Manager Test Events
Don’t assume. Test first.
- Open Meta Events Manager
- Select your Pixel
- Go to Test Events tab
- Open your store in a new browser tab
- Place a test order (use a 100% discount code)
Now check:
- Is the Purchase event showing?
- Is it delayed?
- Is it missing completely?
If it doesn’t appear at all, either the event isn’t firing or the wrong Pixel ID is connected.
This is the first confirmation step when debugging Shopify purchase event not tracking issues.

Step 2: Verify Correct Pixel ID in Shopify
Confirm Pixel Connection
Go to:
Shopify Admin → Settings → Customer Events
OR
Facebook & Instagram Sales Channel
Make sure the Pixel ID connected in Shopify matches the one inside Meta Events Manager.
Many store owners accidentally connect the wrong ad account Pixel. This small mistake alone can completely break purchase tracking.
Step 3: Fix Duplicate Purchase Events
If your purchase event fires twice, optimization becomes inaccurate.
Common Causes of Duplicate Events
1. Manual Pixel Code + Shopify Integration
If your theme.liquid file contains manual code like:
fbq(‘track’, ‘Purchase’)
AND you’re also using Shopify’s Facebook integration — you will get duplicate purchase events.
Remove manual code immediately.
2. Browser Event + Conversions API Conflict
If both events are firing but using different Event IDs, Meta cannot deduplicate properly.
How to Check Deduplication
Inside Events Manager:
- Check Event ID
- Check Browser event
- Check Server event
- Confirm deduplication status
If misconfigured, reconnecting the Shopify Facebook integration often fixes it instantly.
Duplicate tracking is one of the biggest reasons why Shopify purchase event not tracking correctly even though sales are happening.

Step 4: Check Thank You Page Tracking
Why the Thank You Page Matters
The purchase event usually fires on the Thank You page after checkout.
If:
- Customers are redirected elsewhere
- Third-party checkout is used
- Additional scripts are broken
The event may never trigger.
What to Check
- Shopify → Settings → Checkout → Additional Scripts
- Remove outdated or broken tracking code
- Temporarily disable custom checkout modifications
- Test again in incognito mode
A broken Thank You page script is a silent tracking killer.
Step 5: Compare Browser Event vs Conversions API
In 2026, most stores use both browser tracking and Conversions API.
Difference Between the Two
Browser Event
Triggered inside the customer’s browser.
Conversions API (CAPI)
Sent directly from Shopify’s server to Meta.
Both must use the same Event ID for proper deduplication.
If they don’t match:
- Double counting happens
- Or one event gets ignored
Always confirm both are firing correctly inside Test Events.
Step 6: Clear Cache and Test Properly
Sometimes the issue isn’t configuration — it’s testing conditions.
Proper Testing Method
- Use Incognito Mode
- Disable ad blockers
- Clear browser cache
- Use Meta Pixel Helper extension
Many false alarms happen because of cached sessions.
