Grants an Amazon Web Service, Amazon Web Services account, or Amazon Web Services organization 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. Note: Lambda does not support adding policies to version $LATEST.
To grant permission to another account, specify the account ID as the Principal.
To grant permission to an organization defined in Organizations, specify the organization
ID as the PrincipalOrgID. For Amazon Web Services, the principal is a domain-style
identifier that the service defines, such as s3.amazonaws.com or sns.amazonaws.com.
For Amazon Web Services, you can also specify the ARN of the associated resource as
the SourceArn. 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 operation adds a statement to a resource-based permissions policy for the function. For more information about function policies, see Using resource-based policies for Lambda.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginAddPermission and EndAddPermission.
