The Amazon FSx API is a network protocol based on HTTP (RFC 2616). For each API call, you make an HTTP request to the region-specific Amazon FSx API endpoint for the AWS Region where you want to manage file systems. The API uses JSON (RFC 4627) documents for HTTP request/response bodies.

The Amazon FSx API is an RPC model. In this model, there is a fixed set of operations and the syntax for each operation is known to clients without any prior interaction. In the following section, you can find a description of each API operation using an abstract RPC notation. Each has an operation name that doesn't appear on the wire. For each operation, the topic specifies the mapping to HTTP request elements.

The specific Amazon FSx operation to which a given request maps is determined by a combination of the request's method (GET, PUT, POST, or DELETE) and which of the various patterns its Request-URI matches. If the operation is PUT or POST, Amazon FSx extracts call arguments from the Request-URI path segment, query parameters, and the JSON object in the request body.

Although operation names, such as CreateFileSystem, don't appear on the wire, these names are meaningful in AWS Identity and Access Management (IAM) policies. The operation name is also used to name commands in command-line tools and elements of the AWS SDKs. For example, there is a AWS CLI command named create-file-system that maps to the CreateFileSystem operation. The operation name also appears in AWS CloudTrail logs for Amazon FSx API calls.

API endpoints

The API endpoint is the DNS name used as a host in the HTTP URI for the API calls. These API endpoints are specific to AWS Regions. Amazon FSx supports both IPv4-only endpoints and dual stack (IPv4 and IPv6) API endpoints. They take the following form.

IPv4-only endpoint


fsx.aws-region.amazonaws.com

The IPv4-only Amazon FSx API endpoint for the US East (N. Virginia) Region is the following.


fsx.us-east-1.amazonaws.com

For China Regions in the aws-cn partition,the pattern for IPv4 service management endpoints is:


fsx.region.amazonaws.com.rproxy.goskope.com.cn

For example, when managing FSx resources in China (Beijing) Region, you will use the following IPv4 service management endpoint:


fsx---cn-north-1.amazonaws.com.rproxy.goskope.com.cn

Dual stack endpoint

For AWS commercial Regions in the aws partition and AWS GovCloud (US) Regions in the aws-us-gov partition, the pattern for dual-stack endpoints is:


fsx.region.api.aws

For example, when managing FSx resources in US East (N. Virginia) Region, you will use the following service management endpoint:


fsx.us-east-1.api.aws

For China Regions in the aws-cn partition,the pattern for dual-stack endpoints is:


fsx.region.api.amazonwebservices.com.rproxy.goskope.com.cn

For example, when managing FSx resources in China (Beijing) Region, you will use the following service management endpoint:


fsx.cn-north-1.api.amazonwebsservices.com.cn

For a list of AWS Regions that Amazon FSx supports (where you can create and manage file systems), see Amazon FSx in the AWS General Reference.

The region-specific API endpoint defines the scope of the Amazon FSx resources that are accessible when you make an API call. For example, when you call the DescribeFileSystems operation using the preceding endpoint, you get a list of file systems in the US East (N. Virginia) Region Region that have been created in your account.

API Version

The version of the API being used for a call is identified by the first path segment of the request URI, and its form is an ISO 8601 date. The documentation describes API version 2018-03-01.

For information on the necessary permissions for these API operations using IAM policies, see Actions, resources, and condition keys for Amazon FSx in the Service Authorization Reference.
