CfnConnector
- class aws_cdk.aws_transfer.CfnConnector(scope, id, *, access_role, url, as2_config=None, logging_role=None, security_policy_name=None, sftp_config=None, tags=None)
Bases:
CfnResource
Creates the connector, which captures the parameters for a connection for the AS2 or SFTP protocol.
For AS2, the connector is required for sending files to an externally hosted AS2 server. For SFTP, the connector is required when sending files to an SFTP server or receiving files from an SFTP server. For more details about connectors, see Configure AS2 connectors and Create SFTP connectors . .. epigraph:
You must specify exactly one configuration object: either for AS2 ( ``As2Config`` ) or SFTP ( ``SftpConfig`` ).

Example:
# The code below shows an example of how to instantiate this type. # The values are placeholders you should change. from aws_cdk import aws_transfer as transfer # as2_config: Any cfn_connector = transfer.CfnConnector(self, "MyCfnConnector", access_role="accessRole", url="url", # the properties below are optional as2_config=as2_config, logging_role="loggingRole", security_policy_name="securityPolicyName", sftp_config=transfer.CfnConnector.SftpConfigProperty( trusted_host_keys=["trustedHostKeys"], user_secret_id="userSecretId" ), tags=[CfnTag( key="key", value="value" )] )
- Parameters:
scope (
Construct
) – Scope in which this resource is defined.id (
str
) – Construct identifier for this resource (unique in its scope).access_role (
str
) – Connectors are used to send files using either the AS2 or SFTP protocol. For the access role, provide the Amazon Resource Name (ARN) of the AWS Identity and Access Management role to use. For AS2 connectors With AS2, you can send files by callingStartFileTransfer
and specifying the file paths in the request parameter,SendFilePaths
. We use the file’s parent directory (for example, for--send-file-paths /bucket/dir/file.txt
, parent directory is/bucket/dir/
) to temporarily store a processed AS2 message file, store the MDN when we receive them from the partner, and write a final JSON file containing relevant metadata of the transmission. So, theAccessRole
needs to provide read and write access to the parent directory of the file location used in theStartFileTransfer
request. Additionally, you need to provide read and write access to the parent directory of the files that you intend to send withStartFileTransfer
. If you are using Basic authentication for your AS2 connector, the access role requires thesecretsmanager:GetSecretValue
permission for the secret. If the secret is encrypted using a customer-managed key instead of the AWS managed key in Secrets Manager, then the role also needs thekms:Decrypt
permission for that key. For SFTP connectors Make sure that the access role provides read and write access to the parent directory of the file location that’s used in theStartFileTransfer
request. Additionally, make sure that the role providessecretsmanager:GetSecretValue
permission to AWS Secrets Manager .url (
str
) – The URL of the partner’s AS2 or SFTP endpoint.as2_config (
Any
) – A structure that contains the parameters for an AS2 connector object.logging_role (
Optional
[str
]) – The Amazon Resource Name (ARN) of the AWS Identity and Access Management (IAM) role that allows a connector to turn on CloudWatch logging for Amazon S3 events. When set, you can view connector activity in your CloudWatch logs.security_policy_name (
Optional
[str
]) – The text name of the security policy for the specified connector.sftp_config (
Union
[IResolvable
,SftpConfigProperty
,Dict
[str
,Any
],None
]) – A structure that contains the parameters for an SFTP connector object.tags (
Optional
[Sequence
[Union
[CfnTag
,Dict
[str
,Any
]]]]) – Key-value pairs that can be used to group and search for connectors.
Methods
- add_deletion_override(path)
Syntactic sugar for
addOverride(path, undefined)
.- Parameters:
path (
str
) – The path of the value to delete.- Return type:
None
- add_dependency(target)
Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.
- Parameters:
target (
CfnResource
) –- Return type:
None
- add_depends_on(target)
(deprecated) Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
- Parameters:
target (
CfnResource
) –- Deprecated:
use addDependency
- Stability:
deprecated
- Return type:
None
- add_metadata(key, value)
Add a value to the CloudFormation Resource Metadata.
- Parameters:
key (
str
) –value (
Any
) –
- See:
- Return type:
None
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html
Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.
- add_override(path, value)
Adds an override to the synthesized CloudFormation resource.
To add a property override, either use
addPropertyOverride
or prefixpath
with “Properties.” (i.e.Properties.TopicName
).If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.
To include a literal
.
in the property name, prefix with a\
. In most programming languages you will need to write this as"\\."
because the\
itself will need to be escaped.For example:
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"]) cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")
would add the overrides Example:
"Properties": { "GlobalSecondaryIndexes": [ { "Projection": { "NonKeyAttributes": [ "myattribute" ] ... } ... }, { "ProjectionType": "INCLUDE" ... }, ] ... }
The
value
argument toaddOverride
will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.- Parameters:
path (
str
) –The path of the property, you can use dot notation to override values in complex types. Any intermediate keys will be created as needed.
value (
Any
) –The value. Could be primitive or complex.
- Return type:
None
- add_property_deletion_override(property_path)
Adds an override that deletes the value of a property from the resource definition.
- Parameters:
property_path (
str
) – The path to the property.- Return type:
None
- add_property_override(property_path, value)
Adds an override to a resource property.
Syntactic sugar for
addOverride("Properties.<...>", value)
.- Parameters:
property_path (
str
) – The path of the property.value (
Any
) – The value.
- Return type:
None
- apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)
Sets the deletion policy of the resource based on the removal policy specified.
The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.
The resource can be deleted (
RemovalPolicy.DESTROY
), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN
). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT
). A list of resources that support this policy can be found in the following link:- Parameters:
policy (
Optional
[RemovalPolicy
]) –apply_to_update_replace_policy (
Optional
[bool
]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: truedefault (
Optional
[RemovalPolicy
]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resource, please consult that specific resource’s documentation.
- See:
- Return type:
None
- get_att(attribute_name, type_hint=None)
Returns a token for an runtime attribute of this resource.
Ideally, use generated attribute accessors (e.g.
resource.arn
), but this can be used for future compatibility in case there is no generated attribute.- Parameters:

Static Methods
- classmethod is_cfn_element(x)
Returns
true
if a construct is a stack element (i.e. part of the synthesized cloudformation template).Uses duck-typing instead of
instanceof
to allow stack elements from different versions of this library to be included in the same stack.- Parameters:
x (
Any
) –- Return type:
bool
- Returns:
The construct as a stack element or undefined if it is not a stack element.
- classmethod is_cfn_resource(x)
Check whether the given object is a CfnResource.
- Parameters:
x (
Any
) –- Return type:
bool
- classmethod is_construct(x)
Checks if
x
is a construct.Use this method instead of
instanceof
to properly detectConstruct
instances, even when the construct library is symlinked.Explanation: in JavaScript, multiple copies of the
constructs
library on disk are seen as independent, completely different libraries. As a consequence, the classConstruct
in each copy of theconstructs
library is seen as a different class, and an instance of one class will not test asinstanceof
the other class.npm install
will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of theconstructs
library can be accidentally installed, andinstanceof
will behave unpredictably. It is safest to avoid usinginstanceof
, and using this type-testing method instead.- Parameters:
x (
Any
) – Any object.- Return type:
bool
- Returns:
true if
x
is an object created from a class which extendsConstruct
.
As2ConfigProperty
- class CfnConnector.As2ConfigProperty(*, basic_auth_secret_id=None, compression=None, encryption_algorithm=None, local_profile_id=None, mdn_response=None, mdn_signing_algorithm=None, message_subject=None, partner_profile_id=None, signing_algorithm=None)
Bases:
object
A structure that contains the parameters for an AS2 connector object.
- Parameters:
basic_auth_secret_id (
Optional
[str
]) – Provides Basic authentication support to the AS2 Connectors API. To use Basic authentication, you must provide the name or Amazon Resource Name (ARN) of a secret in AWS Secrets Manager . The default value for this parameter isnull
, which indicates that Basic authentication is not enabled for the connector. If the connector should use Basic authentication, the secret needs to be in the following format:{ "Username": "user-name", "Password": "user-password" }
Replaceuser-name
anduser-password
with the credentials for the actual user that is being authenticated. Note the following: - You are storing these credentials in Secrets Manager, not passing them directly into this API. - If you are using the API, SDKs, or CloudFormation to configure your connector, then you must create the secret before you can enable Basic authentication. However, if you are using the AWS management console, you can have the system create the secret for you. If you have previously enabled Basic authentication for a connector, you can disable it by using theUpdateConnector
API call. For example, if you are using the CLI, you can run the following command to remove Basic authentication:update-connector --connector-id my-connector-id --as2-config 'BasicAuthSecretId=""'
compression (
Optional
[str
]) – Specifies whether the AS2 file is compressed.encryption_algorithm (
Optional
[str
]) – The algorithm that is used to encrypt the file. Note the following: - Do not use theDES_EDE3_CBC
algorithm unless you must support a legacy client that requires it, as it is a weak encryption algorithm. - You can only specifyNONE
if the URL for your connector uses HTTPS. Using HTTPS ensures that no traffic is sent in clear text.local_profile_id (
Optional
[str
]) – A unique identifier for the AS2 local profile.mdn_response (
Optional
[str
]) – Used for outbound requests (from an AWS Transfer Family server to a partner AS2 server) to determine whether the partner response for transfers is synchronous or asynchronous. Specify either of the following values: -SYNC
: The system expects a synchronous MDN response, confirming that the file was transferred successfully (or not). -NONE
: Specifies that no MDN response is required.mdn_signing_algorithm (
Optional
[str
]) – The signing algorithm for the MDN response. .. epigraph:: If set to DEFAULT (or not set at all), the value forSigningAlgorithm
is used.message_subject (
Optional
[str
]) – Used as theSubject
HTTP header attribute in AS2 messages that are being sent with the connector.partner_profile_id (
Optional
[str
]) – A unique identifier for the partner profile for the connector.signing_algorithm (
Optional
[str
]) – The algorithm that is used to sign the AS2 messages sent with the connector.
