Synopsis

Calls the AWS Lambda AddPermission API operation.

Syntax

Add-LMPermission
-FunctionName <String>
-Action <String>
-EventSourceToken <String>
-Principal <String>
-Qualifier <String>
-RevisionId <String>
-SourceAccount <String>
-SourceArn <String>
-StatementId <String>
-Select <String>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

Grants an AWS service or another account permission to use a function. You can apply the policy at the function level, or specify a qualifier to restrict access to a single version or alias. If you use a qualifier, the invoker must use the full Amazon Resource Name (ARN) of that version or alias to invoke the function. To grant permission to another account, specify the account ID as the Principal. For AWS services, the principal is a domain-style identifier defined by the service, like s3.amazonaws.com or sns.amazonaws.com. For AWS services, you can also specify the ARN or owning account of the associated resource as the SourceArn or SourceAccount. If you grant permission to a service principal without specifying the source, other accounts could potentially configure resources in their account to invoke your Lambda function. This action adds a statement to a resource-based permissions policy for the function. For more information about function policies, see Lambda Function Policies.

Parameters

-Action <String>
The action that the principal can use on the function. For example, lambda:InvokeFunction or lambda:GetFunction.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-EventSourceToken <String>
For Alexa Smart Home functions, a token that must be supplied by the invoker.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-FunctionName <String>
Amazon.Lambda.Model.AddPermissionRequest.FunctionName
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the FunctionName parameter. The -PassThru parameter is deprecated, use -Select '^FunctionName' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Principal <String>
The AWS service or account that invokes the function. If you specify a service, use SourceArn or SourceAccount to limit who can invoke the function through that service.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-Qualifier <String>
Specify a version or alias to add permissions to a published version of the function.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-RevisionId <String>
Only update the policy if the revision ID matches the ID that's specified. Use this option to avoid modifying a policy that has changed since you last read it.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'Statement'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.Lambda.Model.AddPermissionResponse). Specifying the name of a property of type Amazon.Lambda.Model.AddPermissionResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-SourceAccount <String>
For AWS services, the ID of the account that owns the resource. Use this instead of SourceArn to grant permission to resources that are owned by another account (for example, all of an account's Amazon S3 buckets). Or use it together with SourceArn to ensure that the resource is owned by the specified account. For example, an Amazon S3 bucket could be deleted by its owner and recreated by another account.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-SourceArn <String>
For AWS services, the ARN of the AWS resource that invokes the function. For example, an Amazon S3 bucket or Amazon SNS topic.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-StatementId <String>
A statement identifier that differentiates the statement from others in the same policy.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
