# Unlink assets

An asset, often referred to as a **token**, represents a digital artifact on the TEOS platform that can be stored, managed, and verified on the blockchain.

This endpoint unlinks one or more assets from a source asset. The transaction is created for the asset issuer’s address (the Author field in the Asset model) and must be signed by the asset issuer to complete this action.

**Preconditions:**

* Source asset with the provided uniqueAssetId exists.
* Source asset is created in the currently configured ledger.
* The user owns the source asset issuer's address.
* Target assets with the provided uniqueAssetIds exist and are currently linked.
