Partially update an album with a JSON merge patch

PATCHhttps://api.testingapis.com/api/Albums/{id}Sign in to see this endpoint's URL

Only the fields present in the body change, and nested objects are merged rather than replaced. The ID and unknown fields are never applied; they are listed in ignored. The patched record is validated before it is saved, so a rejected patch changes nothing.

Parameters 1

Name	Type	Description
`id`required	path · integer (int32)	Record ID.

Request body

Optional. application/json, text/json, application/*+json, application/xml, text/xml, application/*+xml. JSON object with the fields to change, e.g. { "price": 12.5 }.

Example body

{"userId": 101}

Responses

200: Patched; returns { message, changed, ignored, data }.
400: The body is not an object, sets a non-nullable field to null, has a wrongly typed value, or the result fails validation.
404: No record has this ID.
