If conversions with cart data metrics are not available or showing up incorrectly, you should verify that the conversion tag parameters are implemented correctly. To do this, complete a test order following these steps to see if the parameters are passed correctly:
Test implementation for web
- Open the Chrome Developer Tools by clicking the Chrome menu 
at the top right corner of your Google Chrome web browser, then select "More Tools".
 - Then click on "Developer Tools".
 - In the "Developer Tools" pane, select "Network".
 - Submit your test order in the Google Chrome web browser.
 - Search for the request that contains your conversion (search for “/conversion”). The query string parameters should include the cart parameters, as shown in this example:
 
mid = aw_merchant_id
       fcntr = aw_feed_country
       flng = aw_feed_language
       dscnt = discount
       item = items (the array) mapping all items with (items.id * items.price * items.quantity)
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:
          
- “Items” tab
              
- item_id
 - price
 - quantity
 
 - In the “Parameters” tab, look for the following
              
- currency
 - discount
 - aw_merchant_id,
 - aw_feed_country
 - aw_feed_language
 
 
 - “Items” tab
