This method replaces the entire user-defined metadata of the specified asset. Unlike the [`PATCH`](/v1.3/api-reference/upload-content/direct-uploads/update-user-metadata) method, which merges your changes with the existing metadata, this method overwrites the stored value in full:
- A key with a value creates or replaces that key.
- A key set to an empty string (`""`) or `null` is ignored.
- A key you omit from the request body is removed.
To clear all metadata, send an empty object (`{}`) in the `user_metadata` field. This produces the same result as the [`DELETE`](/v1.3/api-reference/upload-content/direct-uploads/delete-user-metadata) method.
Request

user_metadatamap from strings to anyRequired
Metadata that helps you categorize your assets. The object contains user-defined keys and values, where keys are strings and values are one of `string`, `integer`, `float`, or `boolean`.
**Example**:

"user_metadata": {
"category": "recentlyAdded",
"batchNumber": 5,
"rating": 9.3,
"needsReview": true
}
