Get Table ACL

Article
12/10/2024

The Get Table ACL operation returns details about any stored access policies that are specified on the table, and it can be used with shared access signatures. For more information, see Define a stored access policy.

The Get Table ACL operation is available in version 2012-02-12 and later.

Note

An access control list (ACL) is a list of access control entries (ACE). Each ACE in an ACL identifies a trustee and specifies the access rights that are allowed, denied, or audited for that trustee. For more information, see Access control lists.

Request

You can construct the Get Table ACL request as follows. We recommend that you use HTTPS. Replace myaccount with the name of your storage account:

Method	Request URI	HTTP version
`GET/HEAD`	`https://myaccount.table.core.windows.net/mytable?comp=acl`	HTTP/1.1

Emulated storage service request

When you're making a request against the emulated storage service, specify the emulator hostname and Azure Table Storage port as 127.0.0.1:10002, followed by the emulated storage account name:

Method	Request URI	HTTP version
`GET/HEAD`	`http://127.0.0.1:10002/devstoreaccount1/mytable?comp=acl`	HTTP/1.1

For more information, see Use the Azurite emulator for local Azure Storage development.

URI parameters

The following additional parameters may be specified on the request URI:

Parameter	Description
`timeout`	Optional. The `timeout` parameter is expressed in seconds. For more information, see Set time-outs for Azure Table Storage operations.

Request headers

The following table describes required and optional request headers.

Request header	Description
`Authorization`	Required. Specifies the authorization scheme, account name, and signature. For more information, see Authorize requests to Azure Storage.
`Date` or `x-ms-date`	Required. Specifies the Coordinated Universal Time (UTC) for the request. For more information, see Authorize requests to Azure Storage.
`x-ms-version`	Required for all authorized requests. Specifies the version of the operation to use for this request. For more information, see Versioning for the Azure Storage services.
`x-ms-client-request-id`	Optional. Provides a client-generated, opaque value with a 1-kibibyte (KiB) character limit that's recorded in the logs when logging is configured. We highly recommend that you use this header to correlate client-side activities with requests that the server receives. For more information, see Monitor Azure Table Storage.

Request body

None.

Response

The response includes an HTTP status code, a set of response headers, and a response body.

Status code

A successful operation returns status code 200 (OK).

For more information about status codes, see Status and error codes.

Response headers

The response for this operation includes the following headers. The response may also include additional standard HTTP headers. All standard headers conform to the HTTP/1.1 protocol specification.

Response header	Description
`x-ms-request-id`	Uniquely identifies the request that was made and can be used to troubleshoot the request. For more information, see Troubleshoot API operations.
`x-ms-version`	Indicates the Azure Table Storage version that was used to execute the request. This header is returned for requests made against version 2009-09-19 or later.
`Date`	A UTC date/time value that's generated by the service, which indicates the time when the response was initiated.
`x-ms-client-request-id`	Can be used to troubleshoot requests and corresponding responses. The value of this header is equal to the value of the `x-ms-client-request-id` header if it's present in the request and the value contains no more than 1,024 visible ASCII characters. If the `x-ms-client-request-id` header isn't present in the request, it won't be present in the response.

Response body

If a stored access policy has been specified for the table, Get Table ACL returns the signed identifier and access policy in the response body.

Authorization

Authorization is required when calling any data access operation in Azure Storage. You can authorize the Get Table ACL operation using Microsoft Entra ID or Shared Key.

To authorize the Get Table ACL operation using Microsoft Entra ID, the security principal needs a custom Azure RBAC role that includes the following RBAC action: Microsoft.Storage/storageAccounts/tableServices/tables/getAcl/action.

Important

Microsoft recommends using Microsoft Entra ID with managed identities to authorize requests to Azure Storage. Microsoft Entra ID provides superior security and ease of use compared to Shared Key authorization.
