# Updates

## September 2026

We've introduced a new authentication flow for partners integrating a single account, and clarified which flow to use across the existing auth guides.

🆕 **New Guide**

* **Direct Integrator Authentication:** Complete walkthrough of the new [Direct Integrator Authentication](/pages/api-essentials/direct-integrator-auth) flow. Aimed at partners with a commercial subscription who integrate their own single account — obtain a refresh token from a hosted login portal, exchange it for access tokens, and call the API without implementing the full authorization flow.


📚 **Guide Improvements**

* **Authentication & Quickstart:** Added "Which flow do I need?" signposts at the top of the [Authentication Guide](/pages/api-essentials/auth) and [Quickstart](/pages/guides/quickstart) so aggregator and direct-integrator partners land on the right page.
* **Refresh Token Behavior:** Documented the direct-integrator refresh-token rotation and reuse-detection behavior.


## July 2026

We've added a new endpoint to help you plan your publishing volume and manage inventory more effectively.

🆕 **New Endpoint**

* **Listing Limits Endpoint:** Complete reference for the new [GET /items/limits](/apis/items/items/getmyitemslimits) endpoint. Returns the listing limits that apply to your account grouped per limit, each entry including the shared
`category_ids`, the `total` capacity, the number of items currently `used`, and the remaining slots `available`.


## December 2025

We have expanded our documentation to cover advanced inventory management scenarios and added new resources to support your integration.

🆕 **New Resources**

* **Frequently Asked Questions (FAQ):** We've added a brand new [FAQ section](/pages/api-essentials/faq) to address common questions about authentication, listings management, and webhooks that weren't covered in the initial release.
* **Inactive Items Endpoint:** Complete reference for the new [GET /items/inactive](/apis/items/items/userinactiveitems) endpoint.


📚 **Guide Improvements**

* **Inventory Management:** The [Listing Guide](/pages/guides/listing) now includes a comprehensive section on:
  * Managing **Subscription Limits** (Active vs. Inactive items).
  * Best practices for **Stock Rotation**.
  * How to use `external_id` and `license_plate` for catalog synchronization.
