AWS Transfer for SFTP (version v1.*.*)

create_server#

Instantiates an autoscaling virtual server based on Secure File Transfer Protocol (SFTP) in AWS. When you make updates to your server or when you work with users, use the service-generated ServerId property that is assigned to the newly created server.

{
  "LoggingRole" : "A value that allows the service to write your SFTP users' activity to your Amazon CloudWatch logs for monitoring and auditing purposes.",
  "HostKey" : "The RSA private key as generated by the ssh-keygen -N \"\" -f my-new-server-key command.  \nIf you aren't planning to migrate existing users from an existing SFTP server to a new AWS SFTP server, don't update the host key. Accidentally changing a server's host key can be disruptive.  \n For more information, see \"https://alpha-docs-aws.amazon.com/transfer/latest/userguide/configuring-servers.html#change-host-key\" in the AWS SFTP User Guide.

  "IdentityProviderType" : "Specifies the mode of authentication for the SFTP server. The default value is SERVICE_MANAGED, which allows you to store and access SFTP user credentials within the AWS Transfer for SFTP service.

create_user#

Creates a user and associates them with an existing Secure File Transfer Protocol (SFTP) server. You can only create and associate users with SFTP servers that have the IdentityProviderType set to SERVICE_MANAGED. Using parameters for CreateUser, you can specify the user name, set the home directory, store the user's public key, and assign the user's AWS Identity and Access Management (IAM) role. You can also optionally add a scope-down policy, and assign metadata with tags that can be used to group and search for users.

{
  "Policy" : "A scope-down policy for your user so you can use the same IAM role across multiple users. This policy scopes down user access to portions of their Amazon S3 bucket. Variables that you can use inside this policy include ${Transfer:UserName}, ${Transfer:HomeDirectory}, and ${Transfer:HomeBucket}.  \nFor scope-down policies, AWS Transfer for SFTP stores the policy as a JSON blob, instead of the Amazon Resource Name (ARN) of the policy. You save the policy as a JSON blob and pass it in the Policy argument. \nFor an example of a scope-down policy, see \"https://docs.aws.amazon.com/transfer/latest/userguide/users.html#users-policies-scope-down\">Creating a Scope-Down Policy. \nFor more information, see \"https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html\" in the AWS Security Token Service API Reference.",
  "Role" : "The IAM role that controls your user's access to your Amazon S3 bucket. The policies attached to this role will determine the level of access you want to provide your users when transferring files into and out of your Amazon S3 bucket or buckets. The IAM role should also contain a trust relationship that allows the SFTP server to access your resources when servicing your SFTP user's transfer requests.",
  "HomeDirectory" : "The landing directory (folder) for a user when they log in to the server using their SFTP client.  \nAn example is <your-Amazon-S3-bucket-name>/home/username.",
  "HomeDirectoryType" : "The type of landing directory (folder) you want your users' home directory to be when they log into the SFTP server. If you set it to PATH, the user will see the absolute Amazon S3 bucket paths as is in their SFTP clients. If you set it LOGICAL, you will need to provide mappings in the HomeDirectoryMappings for how you want to make S3 paths visible to your user.",
  "ServerId" : "A system-assigned unique identifier for an SFTP server instance. This is the specific SFTP server that you added your user to.",
  "UserName" : "A unique string that identifies a user and is associated with a server as specified by the ServerId. This user name must be a minimum of 3 and a maximum of 32 characters long.

start_server#

Changes the state of a Secure File Transfer Protocol (SFTP) server from OFFLINE to ONLINE. It has no impact on an SFTP server that is already ONLINE. An ONLINE server can accept and process file transfer jobs.
The state of STARTING indicates that the server is in an intermediate state, either not fully able to respond, or not fully online. The values of START_FAILED can indicate an error condition.
No response is returned from this call.

{
  "ServerId" : "A system-assigned unique identifier for an SFTP server that you start."
}

stop_server#

Changes the state of an SFTP server from ONLINE to OFFLINE. An OFFLINE server cannot accept and process file transfer jobs. Information tied to your server such as server and user properties are not affected by stopping your server. Stopping a server will not reduce or impact your Secure File Transfer Protocol (SFTP) endpoint billing.
The state of STOPPING indicates that the server is in an intermediate state, either not fully able to respond, or not fully offline. The values of STOP_FAILED can indicate an error condition.
No response is returned from this call.

{
  "ServerId" : "A system-assigned unique identifier for an SFTP server that you stopped."

test_identity_provider#

If the IdentityProviderType of the server is API_Gateway, tests whether your API Gateway is set up successfully. We highly recommend that you call this operation to test your authentication method as soon as you create your server. By doing so, you can troubleshoot issues with the API Gateway integration to ensure that your users can successfully use the service.

{
  "ServerId" : "A system-assigned identifier for a specific server. That server's user authentication method is tested with a user name and password.",
  "UserName" : "This request parameter is the name of the user account to be tested.",
