public interface LambdaAuthorizerConfig
extends software.amazon.jsii.JsiiSerializable

(experimental) Configuration for Lambda authorization in AppSync.

Note that you can only have a single AWS Lambda function configured to authorize your API.

Example:

 import software.amazon.awscdk.services.lambda.*;
 Function authFunction;
 GraphqlApi.Builder.create(this, "api")
         .name("api")
         .schema(Schema.fromAsset(join(__dirname, "appsync.test.graphql")))
         .authorizationConfig(AuthorizationConfig.builder()
                 .defaultAuthorization(AuthorizationMode.builder()
                         .authorizationType(AuthorizationType.LAMBDA)
                         .lambdaAuthorizerConfig(LambdaAuthorizerConfig.builder()
                                 .handler(authFunction)
                                 .build())
                         .build())
                 .build())
         .build();

Method Details

getHandler

@Stability(Experimental)
@NotNull
IFunction getHandler()

(experimental) The authorizer lambda function.

Note: This Lambda function must have the following resource-based policy assigned to it. When configuring Lambda authorizers in the console, this is done for you. To do so with the AWS CLI, run the following:

aws lambda add-permission --function-name "arn:aws:lambda:us-east-2:111122223333:function:my-function" --statement-id "appsync" --principal appsync.amazonaws.com --action lambda:InvokeFunction

getResultsCacheTtl

@Stability(Experimental)
@Nullable
default Duration getResultsCacheTtl()

(experimental) How long the results are cached.

Disable caching by setting this to 0.

Default: Duration.minutes(5)

getValidationRegex

@Stability(Experimental)
@Nullable
default String getValidationRegex()

(experimental) A regular expression for validation of tokens before the Lambda function is called.

Default: - no regex filter will be applied.

builder

@Stability(Experimental)
static LambdaAuthorizerConfig.Builder builder()

Returns:

a LambdaAuthorizerConfig.Builder of LambdaAuthorizerConfig
