Data-source details

How to format item parameters

You can add item parameters and map them to your source fields. If your purchase events have multiple products in a single transaction, you must arrange your item parameters in arrays. The items array should contain information about items included in the event and is repeated for each item.

Deduplication of purchase events

Accurate deduplication of events can only be done when transaction_id for purchase events is collected. Make sure that you’re collecting the same value across tag, Measurement Protocol and Data Import, so that deduplication of events is carried out.

You can also import your copy of the transaction log using to deduplicate with your website measured purchases to improve your purchase measurement. You can add additional item parameters to include details about items sold in your purchases.
