List Containers

The List Containers operation returns a list of the containers under the specified storage account.


The List Containers request may be constructed as follows. HTTPS is recommended. Replace myaccount with the name of your storage account, and with your endpoint’s domain name or IP address.

Method Request URI HTTP Version

The URI must include the forward slash (/) to separate the host name from the path and query portions of the URI. For List Containers operation, the path portion of the URI remains empty.

URI Parameters

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

Parameter Description
prefix Optional. Filters the results to return only containers whose name begins with the specified prefix.
marker Optional. A string value that identifies the portion of the list of containers to be returned with the next listing operation. The operation returns the NextMarker value within the response body if the listing operation did not return all containers remaining to be listed with the current page. The NextMarker value can be used as the value for the marker parameter in a subsequent call to request the next page of list items. The marker value is opaque to the client.

Optional. Specifies the maximum number of containers to return. If the request does not specify maxresults, or specifies a value greater than 5000, the server will return up to 5000 items.


If the listing operation crosses a partition boundary, the service will return a continuation token for retrieving the remainder of the results. For this reason, it is possible that the service will return fewer results than specified by maxresults, or than the default of 5000. If the parameter is set to a value less than or equal to zero, the server returns status code 400 (Bad Request).

include=metadata Optional. Include this parameter to specify that the container’s metadata be returned as part of the response body. All metadata names must adhere to the naming conventions for C# identifiers.
timeout Optional. The timeout parameter is expressed in seconds. For more information, see Setting Timeouts for Blob Service 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 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 Azure Storage Analytics Logging and Windows Azure Logging: Using Logs to Track Storage Requests.

Request Body



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

Status Code

A successful operation returns status code 200 (OK).

For information about status codes, see Status and Error Codes.

Response Headers

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

Response Header Description
Content-Type Standard HTTP/1.1 header. Specifies the format in which the results are returned. Currently, this value is application/xml.
x-ms-request-id This header uniquely identifies the request that was made and can be used for troubleshooting the request. For more information, see Troubleshooting API operations.
x-ms-version Indicates the version of the Blob service used to execute the request.
Date A UTC date/time value generated by the service that indicates when the response was initiated.
x-ms-client-request-id This header 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 is present in the request and the value is at most 1024 visible ASCII characters. If the x-ms-client-request-id header is not present in the request, this header is not present in the response.

Response Body

The format of the response body is as follows.

<?xml version="1.0" encoding="utf-8"?>
<EnumerationResults ServiceEndpoint="">
        <PublicAccess>container | blob</PublicAccess>
        <HasImmutabilityPolicy>true | false</HasImmutabilityPolicy>
        <HasLegalHold>true | false</HasLegalHold>

The Prefix, Marker, and MaxResults elements are only present if they were specified on the URI. The NextMarker element has a value only if the list results are not complete.

The Metadata element is present only if the include=metadata parameter was specified on the URI. Within the Metadata element, the value of each name-value pair is listed within an element corresponding to the pair’s name.

If a metadata name-value pair violates the naming restrictions enforced by the 2009-09-19 version, the response body indicates the problematic name within an x-ms-invalid-name element, as shown in the following XML fragment:

  <MyMetadata1>first value</MyMetadata1>
  <MyMetadata2>second value</MyMetadata2>

Container public permissions are provided in the PublicAccess property. It indicates whether data in the container may be accessed publicly and the level of access. Possible values include:

  • container: Indicates full public read access for container and blob data. Clients can enumerate blobs within the container via anonymous request, but cannot enumerate containers within the storage account.
  • blob: Indicates public read access for blobs. 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.

If this property is not specified in the section, the container is private to the account owner.

HasImmutabilityPolicy is true if the container has an immutability policy set on it, false otherwise. HasLegalHold is true if the container has one or more legal hold(s) on it, false otherwise.


The response body for List Containers returns the container’s last modified time in an element named Last-Modified.


Only the account owner may call this operation.


If you specify a value for the maxresults parameter and the number of containers to return exceeds this value, or exceeds the default value for maxresults, the response body will contain the NextMarker element (also referred to as a continuation token). NextMarker indicates the next container to return on a subsequent request. To return the next set of items, specify the value of NextMarker for the marker parameter on the URI for the subsequent request. The value of NextMarker must be treated as opaque.

If the listing operation crosses a partition boundary, then the service will return a value for the NextMarker element for retrieving the remainder of the results from the next partition. A listing operation that spans more than one partition results in a smaller set of items being returned than is specified by maxresults, or than the default of 5000. Your application should always check for the presence of the NextMarker element when you perform a listing operation, and handle it accordingly.

Containers are listed in alphabetical order in the response body.

The List Containers operation times out after 30 seconds.

Sample Request and Response

The following sample URI requests the list of containers for an account, setting the maximum results to return for the initial operation to 3.


The request is sent with these headers:

x-ms-version: 2016-05-31
x-ms-date: Wed, 26 Oct 2016 22:08:44 GMT
Authorization: SharedKey myaccount:CY1OP3O3jGFpYFbTCBimLn0Xov0vt0khH/D5Gy0fXvg=

The status code and response headers are returned as follows:

HTTP/1.1 200 OK
Transfer-Encoding: chunked
Content-Type: application/xml
Date: Wed, 26 Oct 2016 22:08:54 GMT
x-ms-version: 2016-05-31
Server: Windows-Azure-Blob/1.0 Microsoft-HTTPAPI/2.0

The response XML for this request is as follows. Note that the NextMarker element follows the set of containers and includes the name of the next container to be returned.

<?xml version="1.0" encoding="utf-8"?>
<EnumerationResults ServiceEndpoint="">
        <Last-Modified>Wed, 26 Oct 2016 20:39:39 GMT</Last-Modified>
        <Last-Modified>Wed, 26 Oct 2016 20:39:39 GMT</Last-Modified>
        <Last-Modified>Wed, 26 Oct 2016 20:39:39 GMT</Last-Modified>

The subsequent list operation specifies the marker on the request URI, as follows. The next set of results is returned beginning with the container specified by the marker.
