Reference: https://zuora.ferndocs.com/developers/api-reference/zuora-api/billing-documents/credit-memos/put-reverse-credit-memo ## Authentication - `Authorization` header (bearer token, required) — Use `Bearer {{token}}` in the `Authorization` header for authentication. ## Servers - `https://rest.test.zuora.com` (US Developer & Central Sandbox (incl. Test Drive), default) - `https://rest.sandbox.na.zuora.com` (US API Sandbox Cloud 1) - `https://rest.apisandbox.zuora.com` (US API Sandbox Cloud 2) - `https://rest.na.zuora.com` (US Production Cloud 1) - `https://rest.zuora.com` (US Production Cloud 2) - `https://rest.test.eu.zuora.com` (EU Developer & Central Sandbox) - `https://rest.sandbox.eu.zuora.com` (EU API Sandbox) - `https://rest.eu.zuora.com` (EU Production) - `https://rest.test.ap.zuora.com` (APAC Developer & Central Sandbox) - `https://rest.ap.zuora.com` (APAC Production) ## Request ### Path parameters - `creditMemoKey` (string, required) — The ID or number of the credit memo. For example, 2c92c8955bd63cc1015bd7c151af02ab or CM00000001. ### Headers - `Accept-Encoding` (string, optional) — 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, optional) — 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, optional) — 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, optional) — An entity ID. 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 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, optional) — 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, optional) — The minor API version. For a list of available minor versions, see [API upgrades](https://developer.zuora.com/v1-api-reference/api-upgrades/). ### Body (application/json) This endpoint expects a PutReverseCreditMemoType. - `applyEffectiveDate` (date, optional) — The date when the to-be-reversed credit memo is applied to the newly generated debit memo, in `yyyy-mm-dd` format. The effective date must be later than or equal to the memo date. The default value is the date when you reverse the credit memo and create the debit memo. - `comment` (string, optional) — Comments about the reversal. The comment is used as the comment of the debit memo generated by reversing the specified credit memo. - `memoDate` (date, optional) — The date when the debit memo is created, in `yyyy-mm-dd` format. The memo date must be later than or equal to the credit memo's memo date. The default value is the date when you reverse the credit memo and create the debit memo. - `reasonCode` (string, optional) — A code identifying the reason for the reversal. The value must be an existing reason code or empty. The code is used as the reason code of the debit memo generated by reversing the specified credit memo. If you do not specify a value, Zuora uses the default reason code `Credit memo reversal` for the debit memo. ## Response ### 200 OK - `creditMemo` (PutReverseCreditMemoResponseTypeCreditMemo, optional) — Container for the credit memo that is automatically generated during the reversal of the invoice that is related to the credit memo. If no related invoice is reversed, the value is null. - `debitMemo` (PutReverseCreditMemoResponseTypeDebitMemo, optional) — Container for the debit memo that is automatically generated during the credit memo reversal. - `success` (boolean, optional) — Returns `true` if the request was processed successfully. ## Errors ### 500 Internal Server Error Internal Server Error - `reasons` (list of ErrorResponseReasonsItems, optional) ### 400 Client Request Error Request Errors - `processId` (string, optional) — The ID of the process that handles the operation. - `reasons` (list of CommonResponseReasonsItems, optional) — The container of the error code and message. This field is available only if the `success` field is `false`. - `requestId` (string, optional) — Unique identifier of the request. - `success` (boolean, optional) — Indicates whether the call succeeded. ## Types ### PutReverseCreditMemoResponseTypeCreditMemo Container for the credit memo that is automatically generated during the reversal of the invoice that is related to the credit memo. If no related invoice is reversed, the value is null. - `id` (string, optional) — The ID of the credit memo. ### PutReverseCreditMemoResponseTypeDebitMemo Container for the debit memo that is automatically generated during the credit memo reversal. - `id` (string, optional) — The ID of the debit memo. ### ErrorResponseReasonsItems - `code` (string, optional) — The error code of response. - `message` (string, optional) — The detail information of the error response ### CommonResponseReasonsItems - `code` (string, optional) — The error code of response. - `message` (string, optional) — The detail information of the error response ## Examples **Request** ```json { "applyEffectiveDate": "2017-02-20", "memoDate": "2017-02-20" } ``` **Response** ```json { "debitMemo": { "id": "402890555a40ca7f015a5b099b0e307a" }, "success": true } ``` **SDK Code** ```python response import requests url = "https://rest.test.zuora.com/v1/credit-memos/creditMemoKey/reverse" payload = { "applyEffectiveDate": "2017-02-20", "memoDate": "2017-02-20" } headers = { "Authorization": "Bearer ", "Content-Type": "application/json" } response = requests.put(url, json=payload, headers=headers) print(response.json()) ``` ```javascript response const url = 'https://rest.test.zuora.com/v1/credit-memos/creditMemoKey/reverse'; const options = { method: 'PUT', headers: {Authorization: 'Bearer ', 'Content-Type': 'application/json'}, body: '{"applyEffectiveDate":"2017-02-20","memoDate":"2017-02-20"}' }; try { const response = await fetch(url, options); const data = await response.json(); console.log(data); } catch (error) { console.error(error); } ``` ```go response package main import ( "fmt" "strings" "net/http" "io" ) func main() { url := "https://rest.test.zuora.com/v1/credit-memos/creditMemoKey/reverse" payload := strings.NewReader("{\n \"applyEffectiveDate\": \"2017-02-20\",\n \"memoDate\": \"2017-02-20\"\n}") req, _ := http.NewRequest("PUT", url, payload) req.Header.Add("Authorization", "Bearer ") req.Header.Add("Content-Type", "application/json") res, _ := http.DefaultClient.Do(req) defer res.Body.Close() body, _ := io.ReadAll(res.Body) fmt.Println(res) fmt.Println(string(body)) } ``` ```ruby response require 'uri' require 'net/http' url = URI("https://rest.test.zuora.com/v1/credit-memos/creditMemoKey/reverse") http = Net::HTTP.new(url.host, url.port) http.use_ssl = true request = Net::HTTP::Put.new(url) request["Authorization"] = 'Bearer ' request["Content-Type"] = 'application/json' request.body = "{\n \"applyEffectiveDate\": \"2017-02-20\",\n \"memoDate\": \"2017-02-20\"\n}" response = http.request(request) puts response.read_body ``` ```java response import com.mashape.unirest.http.HttpResponse; import com.mashape.unirest.http.Unirest; HttpResponse response = Unirest.put("https://rest.test.zuora.com/v1/credit-memos/creditMemoKey/reverse") .header("Authorization", "Bearer ") .header("Content-Type", "application/json") .body("{\n \"applyEffectiveDate\": \"2017-02-20\",\n \"memoDate\": \"2017-02-20\"\n}") .asString(); ``` ```php response request('PUT', 'https://rest.test.zuora.com/v1/credit-memos/creditMemoKey/reverse', [ 'body' => '{ "applyEffectiveDate": "2017-02-20", "memoDate": "2017-02-20" }', 'headers' => [ 'Authorization' => 'Bearer ', 'Content-Type' => 'application/json', ], ]); echo $response->getBody(); ``` ```csharp response using RestSharp; var client = new RestClient("https://rest.test.zuora.com/v1/credit-memos/creditMemoKey/reverse"); var request = new RestRequest(Method.PUT); request.AddHeader("Authorization", "Bearer "); request.AddHeader("Content-Type", "application/json"); request.AddParameter("application/json", "{\n \"applyEffectiveDate\": \"2017-02-20\",\n \"memoDate\": \"2017-02-20\"\n}", ParameterType.RequestBody); IRestResponse response = client.Execute(request); ``` ```swift response import Foundation let headers = [ "Authorization": "Bearer ", "Content-Type": "application/json" ] let parameters = [ "applyEffectiveDate": "2017-02-20", "memoDate": "2017-02-20" ] as [String : Any] let postData = JSONSerialization.data(withJSONObject: parameters, options: []) let request = NSMutableURLRequest(url: NSURL(string: "https://rest.test.zuora.com/v1/credit-memos/creditMemoKey/reverse")! as URL, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 10.0) request.httpMethod = "PUT" request.allHTTPHeaderFields = headers request.httpBody = postData as Data let session = URLSession.shared let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in if (error != nil) { print(error as Any) } else { let httpResponse = response as?
