<div style={{ textAlign: "justify", marginBottom: "1.5rem" }}>
  At Topsort, the vendor is your advertiser. If you operate a marketplace, this
  means the vendor is the entity selling products on your platform. Vendors are
  linked to your product catalog, and you can grant members access to their
  analytics or self-service features. New vendors are automatically created when
  you sync your catalog with Topsort.
</div>

<div style={{ textAlign: "justify", marginBottom: "1.5rem" }}>
  Topsort also allows the creation of vendors using the user interface,
  providing full parity with our existing [Catalog
  API](/en/ad-server/catalog/). This feature addresses
  customer requests for a simpler way to create first-party vendors, enabling
  them to run campaigns and test the platform faster.
</div>

## How It Works

<div style={{ textAlign: "justify", marginBottom: "1.5rem" }}>
  There is a simple form to create and bulk upload vendors. Every vendor has a
  **name**, an **ID**, and an **optional picture**.
</div>

<Warning>Once a vendor is created, its ID cannot be changed.</Warning>

## Bulk Upload

A bulk upload tool is available, allowing up to 100 vendors to be created at once. If needed, a sample file can be downloaded.

To assign products from the catalog to a vendor, refer to our [**Ad Server - Catalog**](/en/ad-server/catalog/) documentation.
