2018/01/25 - AWS Lambda - 15 updated api methods
Changes AWS Lambda now supports Revision ID on your function versions and aliases, to track and apply conditional updates when you are updating your function version or alias resources.
{'RevisionId': 'string'}
Adds a permission to the resource policy associated with the specified AWS Lambda function. You use resource policies to grant permissions to event sources that use push model. In a push model, event sources (such as Amazon S3 and custom applications) invoke your Lambda function. Each permission you add to the resource policy allows an event source, permission to invoke the Lambda function.
For information about the push model, see AWS Lambda: How it Works .
If you are using versioning, the permissions you add are specific to the Lambda function version or alias you specify in the AddPermission request via the Qualifier parameter. For more information about versioning, see AWS Lambda Function Versioning and Aliases .
This operation requires permission for the lambda:AddPermission action.

Request Syntax
client.add_permission(
FunctionName='string',
StatementId='string',
Action='string',
Principal='string',
SourceArn='string',
SourceAccount='string',
EventSourceToken='string',
Qualifier='string',
RevisionId='string'
)
string
[REQUIRED]
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 characters in length.
string
[REQUIRED]
A unique statement identifier.
string
[REQUIRED]
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.
string
[REQUIRED]
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.
string
This is optional; however, when granting 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.
Warning
If you add a permission without providing the source ARN, any AWS account that creates a mapping to your function ARN can send events to invoke your Lambda function.
string
This parameter is used for S3 and SES. 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.
string
A unique token that must be supplied by the principal invoking the function. This is currently only used for Alexa Smart Home functions.
string
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
string
An optional value you can use to ensure you are updating the latest update of the function version or alias. If the RevisionID you pass doesn't match the latest RevisionId of the function or alias, it will fail with an error message, advising you to retrieve the latest function version or alias RevisionID using either or .

string
[REQUIRED]
The name you want to assign to the function you are uploading. The function names appear in the console and are returned in the ListFunctions API. Function names are used to specify functions to other AWS Lambda API operations, such as Invoke . Note that the length constraint applies only to the ARN. If you specify only the function name, it is limited to 64 characters in length.
string
[REQUIRED]
The runtime environment for the Lambda function you are uploading.
To use the Python runtime v3.6, set the value to "python3.6". To use the Python runtime v2.7, set the value to "python2.7". To use the Node.js runtime v6.10, set the value to "nodejs6.10". To use the Node.js runtime v4.3, set the value to "nodejs4.3".
Note
Node v0.10.42 is currently marked as deprecated. You must migrate existing functions to the newer Node.js runtime versions available on AWS Lambda (nodejs4.3 or nodejs6.10) as soon as possible. Failure to do so will result in an invalid parameter error being returned. Note that you will have to follow this procedure for each region that contains functions written in the Node v0.10.42 runtime.
string
[REQUIRED]
The Amazon Resource Name (ARN) of the IAM role that Lambda assumes when it executes your function to access any other Amazon Web Services (AWS) resources. For more information, see AWS Lambda: How it Works .
string
[REQUIRED]
The function within your code that Lambda calls to begin execution. For Node.js, it is the module-name .*export* value in your function. For Java, it can be package.class-name::handler or package.class-name . For more information, see Lambda Function Handler (Java) .
dict
[REQUIRED]
The code for the Lambda function.
ZipFile (bytes) --
The contents of your zip file containing your deployment package. If you are using the web API directly, the contents of the zip file must be base64-encoded. If you are using the AWS SDKs or the AWS CLI, the SDKs or CLI will do the encoding for you. For more information about creating a .zip file, see Execution Permissions in the AWS Lambda Developer Guide .
S3Bucket (string) --
Amazon S3 bucket name where the .zip file containing your deployment package is stored. This bucket must reside in the same AWS region where you are creating the Lambda function.
S3Key (string) --

S3ObjectVersion (string) --
The Amazon S3 object (the deployment package) version you want to upload.
string
A short, user-defined function description. Lambda does not use this value. Assign a meaningful description as you see fit.
integer
The function execution time at which Lambda should terminate the function. Because the execution time has cost implications, we recommend you set this value based on your expected execution time. The default is 3 seconds.
integer
The amount of memory, in MB, your Lambda function is given. Lambda uses this memory size to infer the amount of CPU and memory allocated to your function. Your function use-case determines your CPU and memory requirements. For example, a database operation might need less memory compared to an image processing function. The default value is 128 MB. The value must be a multiple of 64 MB.
boolean
This boolean parameter can be used to request AWS Lambda to create the Lambda function and publish a version as an atomic operation.
dict
If your Lambda function accesses resources in a VPC, you provide this parameter identifying the list of security group IDs and subnet IDs. These must belong to the same VPC. You must provide at least one security group and one subnet ID.

dict
The parent object that contains your function's tracing settings.
Mode (string) --
Can be either PassThrough or Active. If PassThrough, Lambda will only trace the request from an upstream service if it contains a tracing header with "sampled=1". If Active, Lambda will respect any tracing header it receives from an upstream service. If no tracing header is received, Lambda will call X-Ray for a tracing decision.
dict

boolean
This boolean parameter can be used to request AWS Lambda to update the Lambda function and publish a version as an atomic operation.
boolean
This boolean parameter can be used to test your request to AWS Lambda to update the Lambda function and publish a version as an atomic operation. It will do all necessary computation and validation of your code but will not upload it or a publish a version. Each time this operation is invoked, the CodeSha256 hash value of the provided code will also be computed and returned in the response.
string
An optional value you can use to ensure you are updating the latest update of the function version or alias. If the RevisionID you pass doesn't match the latest RevisionId of the function or alias, it will fail with an error message, advising you to retrieve the latest function version or alias RevisionID using either or .

Updates the configuration parameters for the specified Lambda function by using the values provided in the request. You provide only the parameters you want to change. This operation must only be used on an existing Lambda function and cannot be used to update the function's code.
If you are using the versioning feature, note this API will always update the $LATEST version of your Lambda function. For information about the versioning feature, see AWS Lambda Function Versioning and Aliases .
This operation requires permission for the lambda:UpdateFunctionConfiguration action.

string
[REQUIRED]
The name of the Lambda function.
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 a 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.
string
The Amazon Resource Name (ARN) of the IAM role that Lambda will assume when it executes your function.
string
The function that Lambda calls to begin executing your function. For Node.js, it is the module-name.export value in your function.
string
A short user-defined function description. AWS Lambda does not use this value. Assign a meaningful description as you see fit.
integer
The function execution time at which AWS Lambda should terminate the function. Because the execution time has cost implications, we recommend you set this value based on your expected execution time. The default is 3 seconds.
integer
The amount of memory, in MB, your Lambda function is given. AWS Lambda uses this memory size to infer the amount of CPU allocated to your function. Your function use-case determines your CPU and memory requirements. For example, a database operation might need less memory compared to an image processing function. The default value is 128 MB. The value must be a multiple of 64 MB.
dict
If your Lambda function accesses resources in a VPC, you provide this parameter identifying the list of security group IDs and subnet IDs. These must belong to the same VPC. You must provide at least one security group and one subnet ID.
SubnetIds (list) --
A list of one or more subnet IDs in your VPC.
(string) --
SecurityGroupIds (list) --
A list of one or more security groups IDs in your VPC.
(string) --
dict
The parent object that contains your environment's configuration settings.
Variables (dict) --
The key-value pairs that represent your environment's configuration settings.
(string) --
(string) --
string
The runtime environment for the Lambda function.
To use the Python runtime v3.6, set the value to "python3.6". To use the Python runtime v2.7, set the value to "python2.7". To use the Node.js runtime v6.10, set the value to "nodejs6.10". To use the Node.js runtime v4.3, set the value to "nodejs4.3". To use the Python runtime v3.6, set the value to "python3.6".
Note
Node v0.10.42 is currently marked as deprecated. You must migrate existing functions to the newer Node.js runtime versions available on AWS Lambda (nodejs4.3 or nodejs6.10) as soon as possible. Failure to do so will result in an invalid parameter error being returned. Note that you will have to follow this procedure for each region that contains functions written in the Node v0.10.42 runtime.
dict
The parent object that contains the target ARN (Amazon Resource Name) of an Amazon SQS queue or Amazon SNS topic.
TargetArn (string) --
The Amazon Resource Name (ARN) of an Amazon SQS queue or Amazon SNS topic you specify as your Dead Letter Queue (DLQ).
string
The Amazon Resource Name (ARN) of the KMS key used to encrypt your function's environment variables. If you elect to use the AWS Lambda default service key, pass in an empty string ("") for this parameter.
dict
The parent object that contains your function's tracing settings.
Mode (string) --
Can be either PassThrough or Active. If PassThrough, Lambda will only trace the request from an upstream service if it contains a tracing header with "sampled=1". If Active, Lambda will respect any tracing header it receives from an upstream service. If no tracing header is received, Lambda will call X-Ray for a tracing decision.
string
An optional value you can use to ensure you are updating the latest update of the function version or alias. If the RevisionID you pass doesn't match the latest RevisionId of the function or alias, it will fail with an error message, advising you to retrieve the latest function version or alias RevisionID using either or .
