Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

AWS Transfer for SFTP is a fully managed service that enables the transfer of files directly into and out of Amazon S3 using the Secure File Transfer Protocol (SFTP)—also known as Secure Shell (SSH) File Transfer Protocol. AWS helps you seamlessly migrate your file transfer workflows to AWS Transfer for SFTP—by integrating with existing authentication systems, and providing DNS routing with Amazon Route 53—so nothing changes for your customers and partners, or their applications. With your data in S3, you can use it with AWS services for processing, analytics, machine learning, and archiving. Getting started with AWS Transfer for SFTP (AWS SFTP) is easy; there is no infrastructure to buy and set up.

Sending a Request Using Transfer

var transfer = new AWS.Transfer();
transfer.createServer(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the Transfer object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var transfer = new AWS.Transfer({apiVersion: '2018-11-05'});

You can also set the API version globally in AWS.config.apiVersions using the transfer service identifier:

AWS.config.apiVersions = {
  transfer: '2018-11-05',
  // other service API versions
};

var transfer = new AWS.Transfer();

  • HostKey — (String)

    The RSA private key as generated by the ssh-keygen -N "" -f my-new-server-key command.

    If 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.

    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.

  • IdentityProviderDetails — (map)

    This parameter is required when the IdentityProviderType is set to API_GATEWAY. Accepts an array containing all of the information required to call a customer-supplied authentication API, including the API Gateway URL. This property is not required when the IdentityProviderType is set to SERVICE_MANAGED.

    • Url — (String)

      The Url parameter provides contains the location of the service endpoint used to authenticate users.

    • InvocationRole — (String)

      The InvocationRole parameter provides the type of InvocationRole used to authenticate the user account.

  • IdentityProviderType — (String)

    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. Use the API_GATEWAY value to integrate with an identity provider of your choosing. The API_GATEWAY setting requires you to provide an API Gateway endpoint URL to call for authentication using the IdentityProviderDetails parameter.

    Possible values include:
    • "SERVICE_MANAGED"
    • "API_GATEWAY"
  • LoggingRole — (String)

    A value that allows the service to write your SFTP users' activity to your Amazon CloudWatch logs for monitoring and auditing purposes.

      This property contains one or more values that you assigned to the key name you create.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.

createUser(params = {}, callback) ⇒ AWS.Request

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.

Service Reference:

• CreateUser

Examples:

Calling the createUser operation

var params = {
  Role: 'STRING_VALUE', /* required */
  ServerId: 'STRING_VALUE', /* required */
  UserName: 'STRING_VALUE', /* required */
  HomeDirectory: 'STRING_VALUE',
  HomeDirectoryMappings: [
    {
      Entry: 'STRING_VALUE', /* required */
      Target: 'STRING_VALUE' /* required */
    },
    /* more items */
  ],
  HomeDirectoryType: PATH | LOGICAL,
  Policy: 'STRING_VALUE',
  SshPublicKeyBody: 'STRING_VALUE',
  Tags: [
    {
      Key: 'STRING_VALUE', /* required */
      Value: 'STRING_VALUE' /* required */
    },
    /* more items */
  ]
};
transfer.createUser(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {}) —
  • HomeDirectory — (String)

    The landing directory (folder) for a user when they log in to the server using their SFTP client.

    An example is <your-Amazon-S3-bucket-name>/home/username.

  • HomeDirectoryType — (String)

    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.

    Possible values include:
    • "PATH"
    • "LOGICAL"
  • HomeDirectoryMappings — (Array<map>)

    Logical directory mappings that specify what S3 paths and keys should be visible to your user and how you want to make them visible. You will need to specify the "Entry" and "Target" pair, where Entry shows how the path is made visible and Target is the actual S3 path. If you only specify a target, it will be displayed as is. You will need to also make sure that your AWS IAM Role provides access to paths in Target. The following is an example.

    '[ "/bucket2/documentation", { "Entry": "your-personal-report.pdf", "Target": "/bucket3/customized-reports/${transfer:UserName}.pdf" } ]'

    In most cases, you can use this value instead of the scope down policy to lock your user down to the designated home directory ("chroot"). To do this, you can set Entry to '/' and set Target to the HomeDirectory parameter value.

    • Entry — required — (String)

      Represents an entry and a target for HomeDirectoryMappings.

    • Target — required — (String)

      Represents the map target that is used in a HomeDirectorymapEntry.

  • Policy — (String)

    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}.

    Note: For 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. For 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. For more information, see "https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html" in the AWS Security Token Service API Reference.
  • Role — (String)

    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.

  • ServerId — (String)

    A system-assigned unique identifier for an SFTP server instance. This is the specific SFTP server that you added your user to.

  • SshPublicKeyBody — (String)

    The public portion of the Secure Shell (SSH) key used to authenticate the user to the SFTP server.

  • Tags — (Array<map>)

    Key-value pairs that can be used to group and search for users. Tags are metadata attached to users for any purpose.

    • Key — required — (String)

      The name assigned to the tag that you create.

    • Value — required — (String)

      This property contains one or more values that you assigned to the key name you create.

  • UserName — (String)

    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. The following are valid characters: a-z, A-Z, 0-9, underscore, and hyphen. The user name can't start with a hyphen.

untagResource(params = {}, callback) ⇒ AWS.Request

Detaches a key-value pair from a resource, as identified by its Amazon Resource Name (ARN). Resources are users, servers, roles, and other entities.

No response is returned from this call.

Service Reference:

• UntagResource

Examples:

Calling the untagResource operation

var params = {
  Arn: 'STRING_VALUE', /* required */
  TagKeys: [ /* required */
    'STRING_VALUE',
    /* more items */
  ]
};
transfer.untagResource(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {}) —
  • Arn — (String)

    This is the value of the resource that will have the tag removed. An Amazon Resource Name (ARN) is an identifier for a specific AWS resource, such as a server, user, or role.

  • TagKeys — (Array<String>)

    TagKeys are key-value pairs assigned to ARNs that can be used to group and search for resources by type. This metadata can be attached to resources for any purpose.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs.

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.

updateServer(params = {}, callback) ⇒ AWS.Request

Updates the server properties after that server has been created.

The UpdateServer call returns the ServerId of the Secure File Transfer Protocol (SFTP) server you updated.

Service Reference:

• UpdateServer

Examples:

Calling the updateServer operation

var params = {
  ServerId: 'STRING_VALUE', /* required */
  EndpointDetails: {
    VpcEndpointId: 'STRING_VALUE'
  },
  EndpointType: PUBLIC | VPC_ENDPOINT,
  HostKey: 'STRING_VALUE',
  IdentityProviderDetails: {
    InvocationRole: 'STRING_VALUE',
    Url: 'STRING_VALUE'
  },
  LoggingRole: 'STRING_VALUE'
};
transfer.updateServer(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {}) —
  • EndpointDetails — (map)

    The virtual private cloud (VPC) endpoint settings that are configured for your SFTP server. With a VPC endpoint, your SFTP server isn't accessible over the public internet.

    • VpcEndpointId — (String)

      The ID of the VPC endpoint.

  • EndpointType — (String)

    The type of endpoint that you want your SFTP server to connect to. You can choose to connect to the public internet or a virtual private cloud (VPC) endpoint. With a VPC endpoint, your SFTP server isn't accessible over the public internet.

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

    • ServerId — (String)

      A system-assigned unique identifier for an SFTP server that the user account is assigned to.

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.

updateUser(params = {}, callback) ⇒ AWS.Request

Assigns new properties to a user. Parameters you pass modify any or all of the following: the home directory, role, and policy for the UserName and ServerId you specify.

The response returns the ServerId and the UserName for the updated user.

Service Reference:

• UpdateUser

Examples:

Calling the updateUser operation

var params = {
  ServerId: 'STRING_VALUE', /* required */
  UserName: 'STRING_VALUE', /* required */
  HomeDirectory: 'STRING_VALUE',
  HomeDirectoryMappings: [
    {
      Entry: 'STRING_VALUE', /* required */
      Target: 'STRING_VALUE' /* required */
    },
    /* more items */
  ],
  HomeDirectoryType: PATH | LOGICAL,
  Policy: 'STRING_VALUE',
  Role: 'STRING_VALUE'
};
transfer.updateUser(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {}) —
  • HomeDirectory — (String)

    A parameter that specifies the landing directory (folder) for a user when they log in to the server using their client.

    An example is <your-Amazon-S3-bucket-name>/home/username.

  • HomeDirectoryType — (String)

    The type of landing directory (folder) you want your users' home directory to be when they log into the SFTP serve. 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.

    Possible values include:
    • "PATH"
    • "LOGICAL"
  • HomeDirectoryMappings — (Array<map>)

    Logical directory mappings that specify what S3 paths and keys should be visible to your user and how you want to make them visible. You will need to specify the "Entry" and "Target" pair, where Entry shows how the path is made visible and Target is the actual S3 path. If you only specify a target, it will be displayed as is. You will need to also make sure that your AWS IAM Role provides access to paths in Target. The following is an example.

    '[ "/bucket2/documentation", { "Entry": "your-personal-report.pdf", "Target": "/bucket3/customized-reports/${transfer:UserName}.pdf" } ]'

    In most cases, you can use this value instead of the scope down policy to lock your user down to the designated home directory ("chroot"). To do this, you can set Entry to '/' and set Target to the HomeDirectory parameter value.

    • Entry — required — (String)

      Represents an entry and a target for HomeDirectoryMappings.

    • Target — required — (String)

      Represents the map target that is used in a HomeDirectorymapEntry.

  • Policy — (String)

    Allows you to supply a scope-down policy for your user so you can use the same AWS Identity and Access Management (IAM) role across multiple users. The policy scopes down user access to portions of your Amazon S3 bucket. Variables you can use inside this policy include ${Transfer:UserName}, ${Transfer:HomeDirectory}, and ${Transfer:HomeBucket}.

    Note: For 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. For 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. For more information, see "https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html" in the AWS Security Token Service API Reference.
  • Role — (String)

    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 Secure File Transfer Protocol (SFTP) server to access your resources when servicing your SFTP user's transfer requests.

  • ServerId — (String)

    A system-assigned unique identifier for an SFTP server instance that the user account is assigned to.

  • UserName — (String)

    A unique string that identifies a user and is associated with a server as specified by the ServerId. This is the string that will be used by your user when they log in to your SFTP server. This user name is a minimum of 3 and a maximum of 32 characters long. The following are valid characters: a-z, A-Z, 0-9, underscore, and hyphen. The user name can't start with a hyphen.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

      A system-assigned unique identifier for an SFTP server instance that the user account is assigned to.

    • UserName — (String)

      The unique identifier for a user that is assigned to the SFTP server instance that was specified in the request.

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.
