# PUT /v1/objects/{}/{}/preferences/{}/categories/{} is deprecated

Knock API deprecated PUT /v1/objects/{}/{}/preferences/{}/categories/{} without giving a shutdown date yet.

The provider has deprecated the PUT /v1/objects/{}/{}/preferences/{}/categories/{} endpoint without a shutdown date. Calls to this endpoint will fail. The endpoint previously handled requests to update a specific category preference for an object preference set.

## What to use instead

Set the object preference set using PUT /v1/objects/{collection}/{object_id}/preferences/{id} with categories passed in the request body.
