***

#### **Added**

**Requestor-ID Validation on Partner API Endpoints**

To prevent unauthorized actions, we have extended `Requestor ID` validation to additional endpoints. This ensures that the natural person linked to the ID has the necessary legal authorization.

**Role Check:** Verifies the natural person has the required role.

**Status Check:** Action is executed only if **both** the natural person and the role are status `ACTIVE`.

**Rejection:** If the role is unassigned, or if the person/role is suspended/inactive, the request is rejected.

**Error Handling:** Missing `Requestor-ID` headers will now return a `400 Bad Request`.

**Affected Endpoints:**

**Taxes & Costs:**

* `POST` /traditional/ex-ante
* `POST` /taxes/tax-exemption-orders
* `PATCH` /taxes/tax-exemption-orders/{id}

***

**Regulatory Documents (PRIIPs)**

Retrieve ETF Key Information Documents (KIDs) To comply with regulatory requirements, we now allow the retrieval of the latest KIDs for ETFs directly via the API.

* New Endpoint: `GET /assets/{isin}/documents`
* Parameters:
  * `isin` (required)
  * `language`: `en` or `de`
  * `type`: `kid`
* Behavior:
  * Synchronously fetches the most recent document (filtering for the best generation method and latest timestamp).
  * Returns the PDF content directly.
  * Returns an empty response if no document is available.

***

**Taxes Domain – Changelog Endpoint**

Added a changelog endpoint for the taxes domain.

Allows partners to track status changes and updates for tax exemption orders.

* New Endpoint: `GET /taxes-changelog`

***

**Document Type: `W_8BEN_E`**

**W-8BEN-E Support (FATCA)**

Added support for uploading W-8BEN-E forms, required for non-U.S. legal entities receiving income from U.S. sources.

* **New Document Type:** `W_8BEN_E`
* **Constraint:** Only allowed for `resourceType: LEGAL_ENTITY`
* **Group:** Part of the "Tax documents" group
* **Requirement:** `Requestor-Id` is mandatory for upload

***

**Partner Webhooks**

Corporate Action Notification

* Introduced a new webhook event type: `CORPORATE_ACTION_NOTIFICATION`.
* This allows partners to receive real-time updates regarding corporate actions affecting assets in the trading universe.

***

#### **Changed**

**Partner Documents Query Parameters**

**Query Parameter: Validity Filter**

Introduced a new query parameter to filter documents based on their validity status.

* **Parameter:** `isValid` (boolean)
* **Behavior:** If set to `true`, the API returns only documents where no expiration date is set (`validUntil` is null), ensuring partners retrieve currently valid documents.

**Crypto Asset Migration (MKR → SKY)**

Following the token conversion of Maker (MKR) to Sky (SKY), we have updated the crypto trading universe.

* Added: `SKY` is now available for trading.
  * Precision: Configured to 8 decimal places.
  * Price feeds and settlement details have been configured.
* Removed: `MKR` has been removed from the available asset list and price feeds.

***

#### **Removed**

**Document Type: `NON_ASSESSMENT_CERTIFICATE`**

* Removed from all Partner API `POST` requests.
