/AWS1/CL_LMD=>ADDPERMISSION()
¶
About AddPermission¶
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.
Method Signature¶
IMPORTING¶
Required arguments:¶
IV_FUNCTIONNAME
TYPE /AWS1/LMDFUNCTIONNAME
/AWS1/LMDFUNCTIONNAME
¶
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.
IV_STATEMENTID
TYPE /AWS1/LMDSTATEMENTID
/AWS1/LMDSTATEMENTID
¶
A statement identifier that differentiates the statement from others in the same policy.
IV_ACTION
TYPE /AWS1/LMDACTION
/AWS1/LMDACTION
¶
The action that the principal can use on the function. For example,
lambda:InvokeFunction
orlambda:GetFunction
.
IV_PRINCIPAL
TYPE /AWS1/LMDPRINCIPAL
/AWS1/LMDPRINCIPAL
¶
The Amazon Web Service 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.
Optional arguments:¶
IV_SOURCEARN
TYPE /AWS1/LMDARN
/AWS1/LMDARN
¶
For Amazon Web Services, 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.
IV_SOURCEACCOUNT
TYPE /AWS1/LMDSOURCEOWNER
/AWS1/LMDSOURCEOWNER
¶
For Amazon Web Service, 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.
IV_EVENTSOURCETOKEN
TYPE /AWS1/LMDEVENTSOURCETOKEN
/AWS1/LMDEVENTSOURCETOKEN
¶
For Alexa Smart Home functions, a token that the invoker must supply.
IV_QUALIFIER
TYPE /AWS1/LMDQUALIFIER
/AWS1/LMDQUALIFIER
¶
Specify a version or alias to add permissions to a published version of the function.
IV_REVISIONID
TYPE /AWS1/LMDSTRING
/AWS1/LMDSTRING
¶
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.
IV_PRINCIPALORGID
TYPE /AWS1/LMDPRINCIPALORGID
/AWS1/LMDPRINCIPALORGID
¶
The identifier for your organization in Organizations. Use this to grant permissions to all the Amazon Web Services accounts under this organization.
IV_FUNCTIONURLAUTHTYPE
TYPE /AWS1/LMDFUNCTIONURLAUTHTYPE
/AWS1/LMDFUNCTIONURLAUTHTYPE
¶
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.
