# Write off a debit memo

Note: This operation is only available if you have Invoice Settlement enabled. The Invoice Settlement feature is generally available as of Zuora Billing Release 296 (March 2021).

If you want to enable Invoice Settlement, see Invoice Settlement Enablement and Checklist Guide for more information.

Writes off a debit memo. 

By writing off a debit memo,  a credit memo is automatically created and applied to the debit memo. The generated  credit memo items and credit memo taxation items are applied to the corresponding  debit memo items and debit memo taxation items respectively.

Note: 
* This API operation  is available only if you have enabled the enhanced write-off permission for your tenant.  Contact Zuora Global Support  to enable this permission.
* The total amount must be equal to the amount entered at the invoice item level.
* If the non revenue impact value  is set to Yes, then the non revenue write off accounting code must be specified.

## Header parameters:

  - `Accept-Encoding` (string)
    Include the Accept-Encoding: gzip header to compress responses as a gzipped file. It can significantly reduce the bandwidth required for a response. 

If specified, Zuora automatically compresses responses that contain over 1000 bytes of data, and the response contains a Content-Encoding header with the compression algorithm so that your client can decompress it.

  - `Content-Encoding` (string)
    Include the Content-Encoding: gzip header to compress a request. With this header specified, you should upload a gzipped file for the request payload instead of sending the JSON payload.

  - `Zuora-Track-Id` (string)
    A custom identifier for tracing the API call. If you set a value for this header, Zuora returns the same value in the response headers. This header enables you to associate your system process identifiers with Zuora API calls, to assist with troubleshooting in the event of an issue.

The value of this field must use the US-ASCII character set and must not include any of the following characters: colon (:), semicolon (;), double quote ("), and quote (').

  - `Zuora-Entity-Ids` (string)
    An entity ID. If you have Zuora Multi-entity enabled and the OAuth token is valid for more than one entity, you must use this header to specify which entity to perform the operation in. If the OAuth token is only valid for a single entity, or you do not have Zuora Multi-entity enabled, you should not set this header.

  - `Zuora-Org-Ids` (string)
    Comma separated IDs. If you have Zuora Multi-Org enabled, 
you can use this header to specify which orgs to perform the operation in. If you do not have Zuora Multi-Org enabled, you should not set this header.

The IDs must be a sub-set of the user's accessible orgs. If you specify an org that the user does not have access to, the operation fails. This header is important in Multi-Org (MO) setups because it defines the organization context under which the API should operate—mainly used for read access or data visibility filtering. If the header is not set, the operation is performed in scope of the user's accessible orgs.

  - `Zuora-Version` (string)
    The minor API version.

For a list of available minor versions, see API upgrades.

## Path parameters:

  - `debitMemoKey` (string, required)
    The ID or number of the invoice. For example, 2c92c8955bd63cc1015bd7c151af02ab or INV-0000001.

## Request fields (application/json):

  - `comment` (string)

The Exclude Billing Item From Revenue field will be automatically set to Yes by default for such non-revenue impacting write off credit memos, and this setting cannot be changed. This enhancement helps ensure that only revenue-impacting items are synchronized with Zuora Revenue, reducing unnecessary data processing.
