You can call NAS API operations by sending HTTP or HTTPS requests based on URLs. Each URL must contain request parameters. This topic describes the syntax of HTTP or HTTPS requests and provides the endpoints of the NAS API.
Sample requests
The following example shows an unencoded URL request to call the CreateFileSystem operation:
http(s)://nas.cn-hangzhou.aliyuncs.com/?Action=CreateFileSystem
&EncryptType=1
&ProtocolType=NFS
&StorageType=Performance
&<Common request parameters>http(s)specifies the protocol that is used for the request.nas.cn-hangzhou.aliyuncs.comspecifies the endpoint of the NAS API.Action=CreateFileSystemspecifies the API operation that you want to call.EncryptType=1,ProtocolType=NFS, andStorageType=Performancespecify the parameters that are required for CreateFileSystem.<Common request parameters>are common parameters defined in the system.
Protocols
You can send requests over HTTP or HTTPS. To ensure data security, we recommend that you send requests over HTTPS.
Endpoints
The following table lists the endpoints of the NAS API. To minimize the network latency, we recommend that you specify the endpoint based on the region where you make API requests.

Request parameters
You must set the Action parameter to the operation that you want to perform. For example, to create a file system, you must set the Action parameter to CreateFileSystem. You must also specify other operation-specific request parameters and common request parameters. For more information, see the common request parameters described in Common parameters.
Encoding
All requests and responses are encoded in UTF-8.
