The following is an example of update Credit Memo. The QuickBooks Credit Memo Id (id) is required to update the Credit Memo(See [Credit Memo](docId\:X6Nlsr2VQhr25341RoqD0) for the available fields)

The request body must include all writable fields of the Credit Memo object. Writable fields omitted from the request body are set to NULL. 

:::hint{type="info"}
Note:  You can only update one record at a time.

- When you want to update specific fields of an entity without affecting others, use a sparse update operation by setting sparse= 'true' in your request. This approach is more efficient and less prone to unintended changes than a full update.
