Overview

Required parameters: [FunctionName, StatementId, Action, Principal]

  action

The AWS Lambda action you want to allow in this statement. Each Lambda action is a string starting with lambda: followed by the API name . For example, lambda:CreateFunction. You can use wildcard (lambda:*) to grant permission for all AWS Lambda actions.

@property (nonatomic, strong) NSString *action

Declared In

AWSLambdaModel.h

  eventSourceToken

A unique token that must be supplied by the principal invoking the function. This is currently only used for Alexa Smart Home functions.

@property (nonatomic, strong) NSString *eventSourceToken

Declared In

AWSLambdaModel.h

  functionName

Name of the Lambda function whose resource policy you are updating by adding a new permission.

You can specify a function name (for example, Thumbnail) or you can specify Amazon Resource Name (ARN) of the function (for example, arn:aws:lambda:us-west-2:account-id:function:ThumbNail). AWS Lambda also allows you to specify partial ARN (for example, account-id:Thumbnail). Note that the length constraint applies only to the ARN. If you specify only the function name, it is limited to 64 character in length.

@property (nonatomic, strong) NSString *functionName

Declared In

AWSLambdaModel.h

  principal

The principal who is getting this permission. It can be Amazon S3 service Principal (s3.amazonaws.com) if you want Amazon S3 to invoke the function, an AWS account ID if you are granting cross-account permission, or any valid AWS service principal such as sns.amazonaws.com. For example, you might want to allow a custom application in another AWS account to push events to AWS Lambda by invoking your function.

@property (nonatomic, strong) NSString *principal

Declared In

AWSLambdaModel.h

  qualifier

You can use this optional query parameter to describe a qualified ARN using a function version or an alias name. The permission will then apply to the specific qualified ARN. For example, if you specify function version 2 as the qualifier, then permission applies only when request is made using qualified function ARN:

arn:aws:lambda:aws-region:acct-id:function:function-name:2

If you specify an alias name, for example PROD, then the permission is valid only for requests made using the alias ARN:

arn:aws:lambda:aws-region:acct-id:function:function-name:PROD

If the qualifier is not specified, the permission is valid only when requests is made using unqualified function ARN.

arn:aws:lambda:aws-region:acct-id:function:function-name

@property (nonatomic, strong) NSString *qualifier

Declared In

AWSLambdaModel.h

  sourceAccount

This parameter is used for S3 and SES only. The AWS account ID (without a hyphen) of the source owner. For example, if the SourceArn identifies a bucket, then this is the bucket owner's account ID. You can use this additional condition to ensure the bucket you specify is owned by a specific account (it is possible the bucket owner deleted the bucket and some other AWS account created the bucket). You can also use this condition to specify all sources (that is, you don't specify the SourceArn) owned by a specific account.

@property (nonatomic, strong) NSString *sourceAccount

Declared In

AWSLambdaModel.h

  sourceArn

This is optional; however, when granting Amazon S3 permission to invoke your function, you should specify this field with the Amazon Resource Name (ARN) as its value. This ensures that only events generated from the specified source can invoke the function.

If you add a permission for the Amazon S3 principal without providing the source ARN, any AWS account that creates a mapping to your function ARN can send events to invoke your Lambda function from Amazon S3.

@property (nonatomic, strong) NSString *sourceArn

Declared In

AWSLambdaModel.h

  statementId

A unique statement identifier.

@property (nonatomic, strong) NSString *statementId

Declared In
