Pass multiple product IDs
If you're using Google Floodlight and support adding multiple products to your cart or purchasing multiple products, you'll need to make adjustments to the Pinterest tag in order to pass back multiple product IDs. This is necessary for running dynamic retargeting campaigns.
Use the macro function and the product IDs parameter in this syntax:
The [product_id] parameter only supports single product ID passback. [product_id] supports multiple comma separated values.
- Sending a single product ID: [product_id] = 123,456,789 will pass the data as single value
- Sending multiple product IDs: [product_ids] = 123,456,789 will split the IDs on the comma and pass back all product IDs as separate and unique values
