# Must Read

> Important information about the Partner API and who it's intended for

## Who is this section for?

The **Partner API Guides** section is designed for **Partner Vendors** who integrate with UniUni to provide services such as drop-off locations, scan events, and package tracking updates.

<Warning>
  **Are you a merchant looking to ship with UniUni?** This section is not for you. Please visit the [API Guides](/en/api-reference/introduction) tab instead, which covers the Client API for creating shipments, managing batches, printing labels, and tracking packages.
</Warning>

## What is the Partner API?

The Partner API allows authorized partner vendors to:

* **Authenticate** using API keys and JWT tokens
* **Submit tracking updates** for packages handled at partner locations
* **Handle errors** gracefully using standardized error codes

If you are a partner vendor and need an API key, please contact your UniUni account representative.
