# updateRecord

Updates an existing record.

## Declaration

```data
CancellablePromise updateRecord(
	UpdateRecordParams params
);
```

## Parameters

- `params`: A dictionary as described in the Discussion section.

## Return Value

Return Value A CancellablePromise with the following resolutions.

## Discussion

Discussion If the promise is successful, it will resolve with one of the following dictionaries: { statusCode: 200; result: CKDBRecordResponse } The promise may reject and throw the following: DocumentedResponseError, if the HTTP status code is 421. The result member will be a dictionary conforming to AuthenticationRequiredError. DocumentedResponseError, if the HTTP status code is none of the above and in the range 400 to 599. The result member will be a dictionary conforming to RequestError. ValidationError, if the parameters to the method are incorrect. A FetchError descendant, if there is a problem with the network request. A reference to the request object can be used to examine the underlying cause. Discussion The params dictionary has the following properties: dictionary UpdateRecordParams {   CKDBModifyRecordRequestBody body;   string containerId;   CKEnvironment environment;   string databaseType;   string zoneName;   string recordName;   boolean? force; } body: Updated record details. If there are assetType fields in your record type, you must upload the assets prior to creating a record using the createAssetUploadUrl operation. If this record will be shared, you must set createShortGuid to true to create a globally unique identifier for this record that your app uses when a share participant accepts a shared record. containerId: The container identifier. See Container. environment: The container environment. For valid values, see CKEnvironment. databaseType: The database type. For valid values, see CKDatabaseType. zoneName: The zone name. See CKDBZone. recordName: The record name. See CKDBRecord. force: If true, forces the operation to work without changeTag. If successful, the response contains a CKDBRecordResponse object with the updated record. If there are assetType fields in your record type, you must upload the assets prior to creating a record using the createAssetUploadUrl operation. If this record will be shared, you must set createShortGuid to true to create a globally unique identifier for this record that your app uses when a share participant accepts a shared record. Node.js example:

import { createConfiguration } from "@apple/cktool.target.nodejs"; import {   CKDatabaseType,   CKEnvironment,   PromisesApi,   createCKDBRecordFieldStringValue } from "@apple/cktool.database";

// These parameters are commonly passed to // operations on records. const defaultParams = {   containerId: "YOUR_CONTAINER_ID",   environment: CKEnvironment.DEVELOPMENT,   databaseType: CKDatabaseType.PUBLIC,   zoneName: "_defaultZone", };

try {   const api = new PromisesApi({     configuration: createConfiguration(),     security: {       // You can obtain tokens from CloudKit Console.       "ManagementTokenAuth": "YOUR_MANAGEMENT_TOKEN",       "UserTokenAuth": "YOUR_USER_TOKEN"     },   });   const { result } = await api.updateRecord({     ...defaultParams,     recordName: "RECORD_NAME",     body: {       recordType: "MyUserAccounts",       fields: {         "lastName": createCKDBRecordFieldStringValue({           value: "Smith-Jones"         }),       }     }   });   // Do something with result.record   console.log(result.record.recordName); } catch(ex) {   // Handle error }
