 CallAwsService getObject = CallAwsService.Builder.create(this, "GetObject")
         .service("s3")
         .action("getObject")
         .parameters(Map.of(
                 "Bucket", myBucket.getBucketName(),
                 "Key", JsonPath.stringAt("$.key")))
         .iamResources(List.of(myBucket.arnForObjects("*")))

getIamResources

@Stability(Stable)

getAdditionalIamStatements

@Stability(Stable)
@Nullable
default List<PolicyStatement> getAdditionalIamStatements()

Additional IAM statements that will be added to the state machine role's policy.

Use in the case where the call requires more than a single statement to be executed, e.g. rekognition:detectLabels requires also S3 permissions to read the object on which it must act.

Default: - no additional statements are added

getIamAction

@Nullable
default String getIamAction()

The action for the IAM statement that will be added to the state machine role's policy to allow the state machine to make the API call.

Use in the case where the IAM action name does not match with the API service/action name, e.g. s3:ListBuckets requires s3:ListAllMyBuckets.

Default: - service:action

getParameters

@Stability(Stable)
@Nullable
default Map<String,Object> getParameters()

Parameters for the API action call.

Use PascalCase for the parameter names.

Default: - no parameters

builder

@Stability(Stable)
static CallAwsServiceProps.Builder builder()

Returns:

a CallAwsServiceProps.Builder of CallAwsServiceProps
