Add Permission
lambda_add_permission | R Documentation |
Grants an Amazon Web Servicesservice, Amazon Web Services account, or Amazon Web Services organization permission to use a function¶
Description¶
Grants an Amazon Web Servicesservice, 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 Servicesservices, the principal is a domain-style identifier
that the service defines, such as s3.amazonaws.com
or
sns.amazonaws.com
. For Amazon Web Servicesservices, 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.
Usage¶
lambda_add_permission(FunctionName, StatementId, Action, Principal,
SourceArn, SourceAccount, EventSourceToken, Qualifier, RevisionId,
PrincipalOrgID, FunctionUrlAuthType)
Arguments¶
FunctionName
[required] The name or ARN of the Lambda function, version, or alias.
Name formats
Function name –
my-function
(name-only),my-function:v1
(with alias).Function ARN –
arn:aws:lambda:us-west-2:123456789012:function:my-function
.Partial ARN –
123456789012:function:my-function
.
You can append a version number or alias to any of the formats. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.
StatementId
[required] A statement identifier that differentiates the statement from others in the same policy.
Action
[required] The action that the principal can use on the function. For example,
lambda:InvokeFunction
orlambda:GetFunction
.Principal
[required] The Amazon Web Servicesservice or Amazon Web Services account that invokes the function. If you specify a service, use
SourceArn
orSourceAccount
to limit who can invoke the function through that service.SourceArn
For Amazon Web Servicesservices, the ARN of the Amazon Web Services resource that invokes the function. For example, an Amazon S3 bucket or Amazon SNS topic.
Note that Lambda configures the comparison using the
StringLike
operator.SourceAccount
For Amazon Web Servicesservice, the ID of the Amazon Web Services account that owns the resource. Use this together with
SourceArn
to ensure that the specified account owns the resource. It is possible for an Amazon S3 bucket to be deleted by its owner and recreated by another account.EventSourceToken
For Alexa Smart Home functions, a token that the invoker must supply.
Qualifier
Specify a version or alias to add permissions to a published version of the function.
RevisionId
Update the policy only 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.
PrincipalOrgID
The identifier for your organization in Organizations. Use this to grant permissions to all the Amazon Web Services accounts under this organization.
FunctionUrlAuthType
The type of authentication that your function URL uses. Set to
AWS_IAM
if you want to restrict access to authenticated users only. Set toNONE
if you want to bypass IAM authentication to create a public endpoint. For more information, see Security and auth model for Lambda function URLs.
