Example:
# The code below shows an example of how to instantiate this type. # The values are placeholders you should change. import aws_cdk.aws_apigatewayv2 as apigatewayv2 cfn_authorizer = apigatewayv2.CfnAuthorizer(self, "MyCfnAuthorizer", api_id="apiId", authorizer_type="authorizerType", name="name", # the properties below are optional authorizer_credentials_arn="authorizerCredentialsArn", authorizer_payload_format_version="authorizerPayloadFormatVersion", authorizer_result_ttl_in_seconds=123, authorizer_uri="authorizerUri", enable_simple_responses=False, identity_source=["identitySource"], identity_validation_expression="identityValidationExpression", jwt_configuration=apigatewayv2.CfnAuthorizer.JWTConfigurationProperty( audience=["audience"], issuer="issuer" ) )
Create a new
AWS::ApiGatewayV2::Authorizer
.- Parameters:
scope (
Construct
) –scope in which this resource is defined.
id (
str
) –scoped id of the resource.
api_id (
str
) – The API identifier.authorizer_type (
str
) – The authorizer type. SpecifyREQUEST
for a Lambda function using incoming request parameters. SpecifyJWT
to use JSON Web Tokens (supported only for HTTP APIs).name (
str
) – The name of the authorizer.authorizer_credentials_arn (
Optional
[str
]) – Specifies the required credentials as an IAM role for API Gateway to invoke the authorizer. To specify an IAM role for API Gateway to assume, use the role’s Amazon Resource Name (ARN). To use resource-based permissions on the Lambda function, specify null. Supported only forREQUEST
authorizers.authorizer_payload_format_version (
Optional
[str
]) – Specifies the format of the payload sent to an HTTP API Lambda authorizer. Required for HTTP API Lambda authorizers. Supported values are1.0
and2.0
. To learn more, see Working with AWS Lambda authorizers for HTTP APIs .authorizer_result_ttl_in_seconds (
Union
[int
,float
,None
]) – The time to live (TTL) for cached authorizer results, in seconds. If it equals 0, authorization caching is disabled. If it is greater than 0, API Gateway caches authorizer responses. The maximum value is 3600, or 1 hour. Supported only for HTTP API Lambda authorizers.authorizer_uri (
Optional
[str
]) – The authorizer’s Uniform Resource Identifier (URI). ForREQUEST
authorizers, this must be a well-formed Lambda function URI, for example,arn:aws:apigateway:us-west-2:lambda:path/2015-03-31/functions/arn:aws:lambda:us-west-2: *{account_id}* :function: *{lambda_function_name}* /invocations
. In general, the URI has this form:arn:aws:apigateway: *{region}* :lambda:path/ *{service_api}*
, where {region} is the same as the region hosting the Lambda function, path indicates that the remaining substring in the URI should be treated as the path to the resource, including the initial/
. For Lambda functions, this is usually of the form/2015-03-31/functions/[FunctionARN]/invocations
.enable_simple_responses (
Union
[bool
,IResolvable
,None
]) –Specifies whether a Lambda authorizer returns a response in a simple format. By default, a Lambda authorizer must return an IAM policy. If enabled, the Lambda authorizer can return a boolean value instead of an IAM policy. Supported only for HTTP APIs. To learn more, see Working with AWS Lambda authorizers for HTTP APIs .
identity_source (
Optional
[Sequence
[str
]]) –The identity source for which authorization is requested. For a
REQUEST
authorizer, this is optional. The value is a set of one or more mapping expressions of the specified request parameters. The identity source can be headers, query string parameters, stage variables, and context parameters. For example, if an Auth header and a Name query string parameter are defined as identity sources, this value is route.request.header.Auth, route.request.querystring.Name for WebSocket APIs. For HTTP APIs, use selection expressions prefixed with$
, for example,$request.header.Auth
,$request.querystring.Name
. These parameters are used to perform runtime validation for Lambda-based authorizers by verifying all of the identity-related request parameters are present in the request, not null, and non-empty. Only when this is true does the authorizer invoke the authorizer Lambda function. Otherwise, it returns a 401 Unauthorized response without calling the Lambda function. For HTTP APIs, identity sources are also used as the cache key when caching is enabled. To learn more, see Working with AWS Lambda authorizers for HTTP APIs . ForJWT
, a single entry that specifies where to extract the JSON Web Token (JWT) from inbound requests. Currently only header-based and query parameter-based selections are supported, for example$request.header.Authorization
.identity_validation_expression (
Optional
[str
]) – This parameter is not used.jwt_configuration (
Union
[IResolvable
,JWTConfigurationProperty
,Dict
[str
,Any
],None
]) – TheJWTConfiguration
property specifies the configuration of a JWT authorizer. Required for theJWT
authorizer type. Supported only for HTTP APIs.
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_depends_on(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_metadata(key, value)
Add a value to the CloudFormation Resource Metadata.
- Parameters:
key (
str
)value (
Any
)
- See:
- Return type:
None
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 intermdediate 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
).- 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 resoure, please consult that specific resource’s documentation.
- Return type:
None
- get_att(attribute_name)
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:
attribute_name (
str
) – The name of the attribute.- Return type:
- get_metadata(key)
Retrieve a value value from the CloudFormation Resource Metadata.
- Parameters:
key (
str
)- See:
- Return type:
Any
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.

- Parameters:
inspector (
TreeInspector
) –tree inspector to collect and process attributes.
- Return type:
None
- override_logical_id(new_logical_id)

new_logical_id (
str
) – The new logical ID to use for this stack element.- Return type:
None
