CfnAuthorizer L1 construct
The AWS::ApiGateway::Authorizer resource creates an authorization layer that API Gateway activates for methods that have authorization enabled.
API Gateway activates the authorizer when a client calls those methods.

notes
For TOKEN or REQUEST 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 .
identitySourcestringidentity_sourcestridentitySourceStringIdentitySourcestringIdentitySource*string#notes
For a TOKEN or COGNITO_USER_POOLS authorizer, this is required and specifies the request header mapping expression for the custom header holding the authorization token submitted by the client. For example, if the token header name is Auth , the header mapping expression is method.request.header.Auth . For the REQUEST authorizer, this is required when authorization caching is enabled. The value is a comma-separated string of one or more mapping expressions of the specified request parameters. For example, if an Auth header, a Name query string parameter are defined as identity sources, this value is method.request.header.Auth, method.request.querystring.Name . These parameters will be used to derive the authorization caching key and to perform runtime validation of the REQUEST authorizer by verifying all of the identity-related request parameters are present, 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. The valid value is a string of comma-separated mapping expressions of the specified request parameters. When the authorization caching is not enabled, this property is optional.
identityValidationExpressionstringidentity_validation_expressionstridentityValidationExpressionStringIdentityValidationExpressionstringIdentityValidationExpression*string#notes
For TOKEN authorizers, this value is a regular expression. For COGNITO_USER_POOLS authorizers, API Gateway will match the aud field of the incoming token from the client against the specified regular expression. It will invoke the authorizer's Lambda function when there is a match. Otherwise, it will return a 401 Unauthorized response without calling the Lambda function. The validation expression does not apply to the REQUEST authorizer.

Valid values are TOKEN for a Lambda function using a single authorization token submitted in a custom header, REQUEST for a Lambda function using incoming request parameters, and COGNITO_USER_POOLS for using an Amazon Cognito user pool.

Parameters
pathpathpathpathPath— The path of the value to delete.
addDependency(target: CfnResource): voiddef add_dependency(self, target: CfnResource) -> Nonepublic void addDependency(CfnResource target)public void AddDependency(CfnResource target)func AddDependency(Target CfnResource)deprecated#This method has been renamed to addResourceDependency to more clearly set it apart from construct.node.addDependency. See the documentation of that function for more details.
addDependsOn(target: CfnResource): voiddef add_depends_on(self, target: CfnResource) -> Nonepublic void addDependsOn(CfnResource target)public void AddDependsOn(CfnResource target)func AddDependsOn(Target CfnResource)deprecated#notes
This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.
This method has been renamed to addResourceDependency, which makes it more clear that this method operates at a different level from the construct-level construct.node.addDependency() mechanism.
addMetadata(key: string, value: any): voiddef add_metadata(self, key: str, value: Any) -> Nonepublic void addMetadata(String key, Object value)public void AddMetadata(string key, object value)func AddMetadata(Key *string, Value interface{})#addOverride(path: string, value: any): voiddef add_override(self, path: str, value: Any) -> Nonepublic void addOverride(String path, Object value)public void AddOverride(string path, object value)func AddOverride(Path *string, Value interface{})#notes · 2 parameters
To add a property override, either use addPropertyOverride or prefix path 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,
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');
would add the overrides
"Properties": {
"GlobalSecondaryIndexes": [
{
"Projection": {
"NonKeyAttributes": [ "myattribute" ]
...
}
...
},
{
"ProjectionType": "INCLUDE"
...
},
]
...
}
The value argument to addOverride 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
pathpathpathpathPath— - The path of the property, you can use dot notation to override values in complex types.valuevaluevaluevalueValue— - The value.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.
This method only adds dependencies between L1 resources. If you are looking for a generic construct-to-construct dependency mechanism that works for all constructs including L2s, use construct.node.addDependency instead.

Parameters
strengthstrengthstrengthstrengthStrength— - The reference strength to use for this resource.
applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): voiddef apply_removal_policy(self, policy: typing.Optional[RemovalPolicy] = None, options: typing.Optional[RemovalPolicyOptions] = None) -> Nonepublic void applyRemovalPolicy(RemovalPolicy policy, RemovalPolicyOptions options)public void ApplyRemovalPolicy(RemovalPolicy? policy = null, RemovalPolicyOptions? options = null)func ApplyRemovalPolicy(Policy RemovalPolicy, Options RemovalPolicyOptions)#notes
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:

Use this method instead of instanceof to properly detect Construct 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 class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof 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 the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.
Parameters
xxxxX— Any object.
Returns: true if x is an object created from a class which extends Construct.
