Get Container ACL operation gets the permissions for the specified container. The permissions indicate whether container data may be accessed publicly.
Beginning with the 2009-09-19 version, the container permissions provide the following options for managing container access:
Full public read access: Container and blob data can be read via anonymous request. Clients can enumerate blobs within the container via anonymous request, but cannot enumerate containers within the storage account.
Public read access for blobs only: Blob data within this container can be read via anonymous request, but container data is not available. Clients cannot enumerate blobs within the container via anonymous request.
No public read access: Container and blob data can be read by the account owner only.
Get Container ACLalso returns details about any container-level access policies specified on the container that may be used with Shared Access Signatures. For more information, see Establishing a Stored Access Policy.
All public access to the container is anonymous, as is access via a Shared Access Signature.
Get Container ACL request may be constructed as follows. HTTPS is recommended. Replace myaccount with the name of your storage account:
|Method||Request URI||HTTP Version|
Emulated Storage Service URI
When making a request against the emulated storage service, specify the emulator hostname and Blob service port as
127.0.0.1:10000, followed by the emulated storage account name:
|Method||Request URI||HTTP Version|
For more information, see Using the Azure Storage Emulator for Development and Testing.
The following additional parameters may be specified on the request URI.
The following table describes required and optional request headers.
||Required. Specifies the authentication scheme, account name, and signature. For more information, see Authentication for the Azure Storage Services.|
||Required. Specifies the Coordinated Universal Time (UTC) for the request. For more information, see Authentication for the Azure Storage Services.|
||Optional, version 2012-02-12 and newer. If specified,
||Required for all authenticated requests. Specifies the version of the operation to use for this request. For more information, see Versioning for the Azure Storage Services.|
||Optional. Provides a client-generated, opaque value with a 1 KB character limit that is recorded in the analytics logs when storage analytics logging is enabled. Using this header is highly recommended for correlating client-side activities with requests received by the server. For more information, see About Storage Analytics Logging and Azure Logging: Using Logs to Track Storage Requests.|
The response includes an HTTP status code, a set of response headers, and a response body.
A successful operation returns status code
For information about status codes, see Status and Error Codes.
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.
||Indicates whether data in the container may be accessed publicly and the level of access. Possible values include:
If this header is not returned in the response, the container is private to the account owner.
||The entity tag for the container. If the request version is 2011-08-18 or newer, the ETag value will be in quotes.|
||Returns the date and time the container was last modified. The date format follows RFC 1123. For more information, see Representation of Date-Time Values in Headers.
Any operation that modifies the container or its properties or metadata updates the last modified time. Operations on blobs do not affect the last modified time of the container.
||This header uniquely identifies the request that was made and can be used for troubleshooting the request. For more information, see Troubleshooting API Operations.|
||Indicates the version of the Blob service used to execute the request. This header is returned for requests made against version 2009-09-19 and later.|
||A UTC date/time value generated by the service that indicates the time at which the response was initiated.|
If a container-level access policy has been specified for the container,
Get Container ACL returns the signed identifier and access policy in the response body.

Only the account owner may call this operation.
Only the account owner may read data in a particular storage account, unless the account owner has specified that blobs within the container are available for public read access, or made resources in the container available via a Shared Access Signature.
