Update credit memos

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 multiple credit memos. You can update a maximum of 50 credit memos in one single request.

The credit memos that are updated are each in separate database transactions. If the update of one credit memo fails, other credit memos can still be updated successfully.

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 credit memos only if you have the user permission. See Billing Roles for more information.

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 should not set this header.


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.

If the header is not set, the operation is performed in scope of the user's accessible orgs.


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