# Project-Specific Product List

In all methods on vapi.co that return a response as a list, all products available in the Vademecum database are listed within the response.

{% hint style="danger" %}
If you are setting up a vapi.co integration for projects with a smaller product portfolio, this may cause you to consume excess query credits.
{% endhint %}

In such cases, you can filter the products included in the response by using the Custom Product Lists feature. 

### How to use?

1. Click the "Product Lists" menu on the vapi.co dashboard. (<https://www.vapi.co/product-list/index>)\ <br>

2. Create a CSV file containing the barcode list of the products in your project portfolio in the format shown in the description, and upload it.<br>

3. Subsequently, you will have access to the list of barcodes from your uploaded list that match the products in the Vademecum database.<br>

Now, across all methods that return a response as a list, only the response for the products whose barcodes you uploaded will be returned.
