Update a credit 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). This feature includes Unapplied Payments, Credit and Debit Memo, and Invoice Item Settlement. If you want to enable Invoice Settlement, see Invoice Settlement Enablement and Checklist Guide for more information.

Updates the basic and finance information about a credit memo. Currently, Zuora supports updating tax-exclusive memo items, but does not support updating tax-inclusive memo items.

If the amount of a memo item is updated, the tax will be recalculated in the following conditions:

  • The memo is created from a product rate plan charge and you use Avalara to calculate the tax.
  • The memo is created from an invoice and you use Avalara or Zuora Tax to calculate the tax.

You can update a credit memo only if you have the user permission. See Billing Roles for more information.

path Parameters

The unique ID or number of a credit memo. For example, 8a8082e65b27f6c3015ba45ff82c7172 or CM00000001.

header Parameters

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.


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.


The value is in the Bearer {token} format where {token} is a valid OAuth token generated by calling Create an OAuth token.

string <= 64 characters

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 (').


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 do not need to set this header.

Request Body schema: application/json

Whether the credit memo automatically applies to the invoice upon posting.

string [ 0 .. 255 ] characters

Comments about the credit memo.

string <date>

The date when the credit memo takes effect.


Whether the credit memo is excluded from the rule of automatically applying unapplied credit memos to invoices and debit memos during payment runs. If you set this field to true, a payment run does not pick up this credit memo or apply it to other invoices or debit memos.

Array of objects (items)

Container for credit memo items.


A code identifying the reason for the transaction. The value must be an existing reason code or empty. If you do not specify a value, Zuora uses the default reason code.


Whether the credit memo is transferred to an external accounting system. Use this field for integration with accounting systems, such as NetSuite.
