Using the FETCH function we specify the URL, pass the product ID from our report and dynamically retrieve the associated details from a server(API call). Note that we have used the [CONCATENATE ](https://docs.inforiver.com/~/changes/mS6jwvARNLHpKqBa4cT9/formula-syntax/text-formatting-functions/concatenate)function to concatenate the URL and the Product ID to be passed to fetch the data.
