# What is a Product?

**A product** is an item registered in your project.

Go to **Database** → **Products** to view all your products:

You can transfer details of **product groups** to Maestra. A product group is an overarching entity that encompasses individual products.

For example, a specific sweatshirt model can be a product group, while all the available size options of this sweatshirt are separate products.

So a size M sweatshirt and a size L sweatshirt are two different products within one parent product group.

Every product uploaded to Maestra has an **external ID** from the external system. Maestra automatically generates its own internal ID for every product.

## Products have default fields

* name;
* description (this may contain HTML layout elements — if it does, there must be escaped characters);
* stock availability;
* vendor;
* external group ID;
* external ID;
* price;
* old price;
* product page URL;
* image URL;
* shelf life;
* category.

You can also add [custom fields](/api-integrations/how-to-create-a-custom-field) if necessary.

Products can be combined into segments based on conditions or into static segments.

## The following customer actions can be linked to products

* Purchases
* Browsing
* Subscribing to price drop notifications
* Subscribing to back in stock notifications,
* Adding/deleting/changing a product in the user’s product list (in the Cart, Favorites, etc.)

***

* Product group browse
* Subscribing to price drop notifications for product groups
* Subscribing to back in stock notifications for a product group
* Adding/deleting/changing a product in the user’s product list (in the Cart, Favorites, etc.).

## You can filter and find the following actions in the system

* **Related to product**: browse, add/delete/change a product or a product group in a product list.
* **Related to product category**: product category browse.
* **Order**: product purchase.

In order to find these actions, use conditions as a filter to narrow your search.

## How to add products to the system

You have lots of options when it comes to uploading products to your Maestra project. You can choose to:

* Manually add products via the UI;
* Import and update a product in real time;
* Transfer a CSV file using a POST request;
* Import a CSV file from an FTP server.
