## Request Parameters
<a name="API_UpdateLocationAzureBlob_RequestParameters"></a>

For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [AccessTier](#API_UpdateLocationAzureBlob_RequestSyntax) **   <a name="DataSync-UpdateLocationAzureBlob-request-AccessTier"></a>
Specifies the access tier that you want your objects or files transferred into. This only applies when using the location as a transfer destination. For more information, see [Access tiers](https://docs.amazonaws.cn/datasync/latest/userguide/creating-azure-blob-location.html#azure-blob-access-tiers).  
Type: String  
Valid Values: `HOT | COOL | ARCHIVE`   
Required: No

 ** [AgentArns](#API_UpdateLocationAzureBlob_RequestSyntax) **   <a name="DataSync-UpdateLocationAzureBlob-request-AgentArns"></a>
(Optional) Specifies the Amazon Resource Name (ARN) of the DataSync agent that can connect with your Azure Blob Storage container. If you are setting up an agentless cross-cloud transfer, you do not need to specify a value for this parameter.  
You can specify more than one agent. For more information, see [Using multiple agents for your transfer](https://docs.amazonaws.cn/datasync/latest/userguide/multiple-agents.html).  
You cannot add or remove agents from a storage location after you initially create it.
Type: Array of strings  
Array Members: Minimum number of 1 item. Maximum number of 8 items.  
Length Constraints: Maximum length of 128.  
Pattern: `^arn:(aws|aws-cn|aws-us-gov|aws-eusc|aws-iso|aws-iso-b):datasync:[a-z\-0-9]+:[0-9]{12}:agent/agent-[0-9a-z]{17}$`   
Required: No

 ** [AuthenticationType](#API_UpdateLocationAzureBlob_RequestSyntax) **   <a name="DataSync-UpdateLocationAzureBlob-request-AuthenticationType"></a>
Specifies the authentication method DataSync uses to access your Azure Blob Storage. DataSync can access blob storage using a shared access signature (SAS).  
Type: String  
Valid Values: `SAS | NONE`   
Required: No

 ** [BlobType](#API_UpdateLocationAzureBlob_RequestSyntax) **   <a name="DataSync-UpdateLocationAzureBlob-request-BlobType"></a>
Specifies the type of blob that you want your objects or files to be when transferring them into Azure Blob Storage. Currently, DataSync only supports moving data into Azure Blob Storage as block blobs. For more information on blob types, see the [Azure Blob Storage documentation](https://learn.microsoft.com/en-us/rest/api/storageservices/understanding-block-blobs--append-blobs--and-page-blobs).  
Type: String  
Valid Values: `BLOCK`   
Required: No

 ** [CmkSecretConfig](#API_UpdateLocationAzureBlob_RequestSyntax) **   <a name="DataSync-UpdateLocationAzureBlob-request-CmkSecretConfig"></a>
Specifies configuration information for a DataSync-managed secret, such as an authentication token or set of credentials that DataSync uses to access a specific transfer location, and a customer-managed Amazon KMS key.  
Type: [CmkSecretConfig](API_CmkSecretConfig.md) object  
Required: No

 ** [CustomSecretConfig](#API_UpdateLocationAzureBlob_RequestSyntax) **   <a name="DataSync-UpdateLocationAzureBlob-request-CustomSecretConfig"></a>
Specifies configuration information for a customer-managed secret, such as an authentication token or set of credentials that DataSync uses to access a specific transfer location, and a customer-managed Amazon Identity and Access Management (IAM) role that provides access to the secret.  
Type: [CustomSecretConfig](API_CustomSecretConfig.md) object  
Required: No

 ** [LocationArn](#API_UpdateLocationAzureBlob_RequestSyntax) **   <a name="DataSync-UpdateLocationAzureBlob-request-LocationArn"></a>
Specifies the ARN of the Azure Blob Storage transfer location that you're updating.  
Type: String  
Length Constraints: Maximum length of 128.  
Pattern: `^arn:(aws|aws-cn|aws-us-gov|aws-eusc|aws-iso|aws-iso-b):datasync:[a-z\-0-9]+:[0-9]{12}:location/loc-[0-9a-z]{17}$`   
Required: Yes

 ** [SasConfiguration](#API_UpdateLocationAzureBlob_RequestSyntax) **   <a name="DataSync-UpdateLocationAzureBlob-request-SasConfiguration"></a>
Specifies the SAS configuration that allows DataSync to access your Azure Blob Storage.  
Type: [AzureBlobSasConfiguration](API_AzureBlobSasConfiguration.md) object  
Required: No

 ** [Subdirectory](#API_UpdateLocationAzureBlob_RequestSyntax) **   <a name="DataSync-UpdateLocationAzureBlob-request-Subdirectory"></a>
