Set up and test reporting with conversions with cart data

Step 3: Test correct implementation of conversions with cart data

Next: Conversions with cart data parameters

If your conversions with cart data metrics are missing or showing incorrect data, verify if your conversion tag parameters are implemented correctly. Follow the steps below to complete a test order and inspect the data payload.

Test implementation for web

Keep the Chrome Developer Tools open throughout the purchase journey to ensure that the tag assistant captures the full data flow.

Open a new window in Google Chrome.
Select the three-dot icon at the top right corner of your Google Chrome web browser, then select More Tools to open Chrome Developer Tools.
Select Developer Tools.
In the Developer Tools pane, select Network.
Complete a test purchase in your browser window with the Network tab open.
When you reach the final conversion page, go to the Filter search box at the top-left corner of the Network tab.
Depending on how you have set up Conversions with Cart Data,, search for one of the following terms:
- For Google Ads or Search Ads 360: Search for “/conversion” or your specific conversion ID / label.
- For Google Analytics: Search for “collect”.
Select the matching network request name to view its details.
Look at the query string parameters under Headers and check if the following data points populate correctly based on your test cart:
- mid: Your Merchant Center ID
- fcntr: Feed Country (for example, US, GBR)
- flng: Feed Language (for example, en)
- dscnt: Order discount amount (if applicable)
- item: The product array mapping all items in the format of [item_id * price * quantity]

Note: While a successful test order verifies that your code structure and tag parameters are firing accurately for that specific transaction, it doesn’t guarantee that the data is flowing across all transactions.

After your initial test transaction is validated, monitor your in-UI diagnostics for the next 7 days to ensure consistent, healthy data flow across all live transactions before finalizing your setup.

Test Implementation for App Conversions

Enable Debug mode on your development device and use the DebugView to verify purchase event parameters.
Look for a purchase event and click into it. A panel will appear on the right, here you will be able to check whether the following cart parameters are appearing:
1. “Items” tab
  1. item_id
  2. price
  3. quantity
2. In the “Parameters” tab, look for the following
  1. currency
  2. discount
  3. aw_merchant_id,
  4. aw_feed_country
  5. aw_feed_language
