If you want to enable Invoice Settlement, see [Invoice Settlement Enablement and Checklist Guide](https://knowledgecenter.zuora.com/Billing/Billing_and_Payments/Invoice_Settlement/Invoice_Settlement_Migration_Checklist_and_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.

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](https://knowledgecenter.zuora.com/Billing/Billing_and_Payments/Invoice_Settlement/Invoice_Settlement_Migration_Checklist_and_Guide)\\ \\ for more information. \\n\\nWhether to cancel a credit memo synchronously or asynchronously depends on the number of memo items contained in the credit memo. By default, if a credit memo contains less than 1000 items, the credit memo is canceled synchronously. Otherwise, the credit memo is canceled asynchronously. If you want to change the threshold, submit a request at <a href=\"http://support.zuora.com/\" target=\"_blank\">Zuora Global Support</a>.

        :param credit_memo_key: The unique ID or number of a credit memo. For example, 8a8082e65b27f6c3015ba45ff82c7172 or CM00000001. (required)
        :type credit_memo_key: str
        :param accept_encoding: 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. 
        :type accept_encoding: str
        :param content_encoding: 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.

        :type authorization: str
        :param zuora_track_id: 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 (`'`).

If you have [Zuora Multi-entity](https://knowledgecenter.zuora.com/BB_Introducing_Z_Business/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 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.

        :type credit_memo_key: str
        :param accept_encoding: 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. 
        :type accept_encoding: str

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.

        **Note:** This operation is only available if you have [Invoice Settlement](https://knowledgecenter.zuora.com/Billing/Billing_and_Payments/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](https://knowledgecenter.zuora.com/Billing/Billing_and_Payments/Invoice_Settlement/Invoice_Settlement_Migration_Checklist_and_Guide) for more information.   Creates an ad-hoc credit memo from a product rate plan charge. Zuora supports the creation of credit memos from any type of product rate plan charge. The charges can also have any amount and any charge model, except for discout charge models.   When credit memos are created from product rate plan charges, the specified amount with decimal places is now validated based on the decimal places supported by each currency.  You can create a credit memo only if you have the user permission.

See [Create and Edit Notifications](https://knowledgecenter.zuora.com/CF_Users_and_Administrators/Notifications/C_Create_Notifications#section_2) for more information.     - Zuora sends the email messages based on the email template you set. You can set the email template to use in the **Delivery Options** panel of the **Edit notification** dialog from the Zuora UI. By default, the **Manual Email for Credit Memo Default Template** template is used. See [Create and Edit Email Templates](https://knowledgecenter.zuora.com/CF_Users_and_Administrators/Notifications/Create_Email_Templates) for more information.     - The credit memos are sent only to the work email addresses or personal email addresses of the Bill To contact if the following conditions are all met:      * The `useEmailTemplateSetting` field is set to `false`.     * The email addresses are not specified in the `emailAddresses` field.

With this header specified, the Zuora server can identify subsequent retries of the same request using this value, which prevents the same operation from being performed multiple times by accident.  
        :type idempotency_key: str

        :type accept_encoding: str

        **Note:** This operation is only available if you have [Invoice Settlement](https://knowledgecenter.zuora.com/Billing/Billing_and_Payments/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](https://knowledgecenter.zuora.com/Billing/Billing_and_Payments/Invoice_Settlement/Invoice_Settlement_Migration_Checklist_and_Guide) for more information.   Retrieves the information about all parts of a credit memo. A credit memo can consist of an unapplied part, and several parts applied to invoices and debit memos. You can use this operation to get all the applied and unapplied portions of a credit memo. Note that a fully refunded credit memo does not contain any credit memo part. 

        :param credit_memo_key: The unique ID or number of a credit memo. For example, 8a8082e65b27f6c3015ba45ff82c7172.  (required)
        :type credit_memo_key: str
        :param accept_encoding: 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. 
        :type accept_encoding: str
        :param content_encoding: 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. 
        :type content_encoding: str
        :param authorization: The value is in the `Bearer {token}` format where {token} is a valid OAuth token generated by calling [Create an OAuth token](https://www.zuora.com/developer/api-references/api/operation/createToken). 
        :type authorization: str
        :param zuora_track_id: 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.

        :type zuora_entity_ids: str
        :param page: The index number of the page that you want to retrieve. This parameter is dependent on `pageSize`. You must set `pageSize` before specifying `page`. For example, if you set `pageSize` to `20` and `page` to `2`, the 21st to 40th records are returned in the response.

        :type zuora_version: str
        :param zuora_org_ids: 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.

                                 timeout. It can also be a pair (tuple) of

        :param credit_memo_key: The ID or number of the credit memo that you want to upload a PDF file for. For example, 402890555a7e9791015a879f064a0054 or CM00000001.  (required)
        :type credit_memo_key: str
        :param idempotency_key: Specify a unique idempotency key if you want to perform an idempotent POST or PATCH request. Do not use this header in other request types.   With this header specified, the Zuora server can identify subsequent retries of the same request using this value, which prevents the same operation from being performed multiple times by accident.  
        :type idempotency_key: str
        :param accept_encoding: 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. 
        :type accept_encoding: str
        :param content_encoding: 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.

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. 
        :type zuora_entity_ids: str
        :param zuora_track_id: 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 (`'`).

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.

        **Note:** This operation is only available if you have [Invoice Settlement](https://knowledgecenter.zuora.com/Billing/Billing_and_Payments/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](https://knowledgecenter.zuora.com/Billing/Billing_and_Payments/Invoice_Settlement/Invoice_Settlement_Migration_Checklist_and_Guide) for more information.   Write off a fully unapplied credit memo. When writing off a credit memo, a debit memo is automatically created, and then the credit memo to be written off is fully applied to the debit memo.  Note that this operation only supports writing off credit memos that are fully unapplied. Credit memos that are not fully unapplied cannot be written off by this operation.  

        :param credit_memo_key: The unique ID or number of a credit memo. For example, 8a8082e65b27f6c3015ba45ff82c7172.  (required)

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. 
        :type accept_encoding: str

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 (`'`).
