METHODS
AddLayerVersionPermission
- Action => Str
- LayerName => Str
- Principal => Str
- StatementId => Str
- VersionNumber => Int
- [OrganizationId => Str]
- [RevisionId => Str]
Each argument is described in detail in: Paws::Lambda::AddLayerVersionPermission
Returns: a Paws::Lambda::AddLayerVersionPermissionResponse instance
Adds permissions to the resource-based policy of a version of an AWS Lambda layer (https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html). Use this action to grant layer usage permission to other accounts. You can grant permission to a single account, all AWS accounts, or all accounts in an organization.
To revoke permission, call RemoveLayerVersionPermission with the statement ID that you specified when you added it.
AddPermission
- Action => Str
- FunctionName => Str
- Principal => Str
- StatementId => Str
- [EventSourceToken => Str]
- [Qualifier => Str]
- [RevisionId => Str]
- [SourceAccount => Str]
- [SourceArn => Str]
Each argument is described in detail in: Paws::Lambda::AddPermission
Returns: a Paws::Lambda::AddPermissionResponse instance
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 permission policy for the function. For more information about function policies, see Lambda Function Policies (https://docs.aws.amazon.com/lambda/latest/dg/access-control-resource-based.html).
CreateAlias
- FunctionName => Str
- FunctionVersion => Str
- Name => Str
- [Description => Str]
- [RoutingConfig => Paws::Lambda::AliasRoutingConfiguration]
Each argument is described in detail in: Paws::Lambda::CreateAlias
Returns: a Paws::Lambda::AliasConfiguration instance
Creates an alias (https://docs.aws.amazon.com/lambda/latest/dg/versioning-aliases.html) for a Lambda function version. Use aliases to provide clients with a function identifier that you can update to invoke a different version.
You can also map an alias to split invocation requests between two versions. Use the RoutingConfig
parameter to specify a second version and the percentage of invocation requests that it receives.
CreateEventSourceMapping
- EventSourceArn => Str
- FunctionName => Str
- [BatchSize => Int]
- [Enabled => Bool]
- [StartingPosition => Str]
- [StartingPositionTimestamp => Str]
Each argument is described in detail in: Paws::Lambda::CreateEventSourceMapping
Returns: a Paws::Lambda::EventSourceMappingConfiguration instance
Creates a mapping between an event source and an AWS Lambda function. Lambda reads items from the event source and triggers the function.
For details about each event source type, see the following topics.
Using AWS Lambda with Amazon Kinesis (https://docs.aws.amazon.com/lambda/latest/dg/with-kinesis.html)

CreateFunction
- Code => Paws::Lambda::FunctionCode
- FunctionName => Str
- Handler => Str
- Role => Str
- Runtime => Str
- [DeadLetterConfig => Paws::Lambda::DeadLetterConfig]
- [Description => Str]
- [Environment => Paws::Lambda::Environment]
- [KMSKeyArn => Str]
- [Layers => ArrayRef[Str|Undef]]
- [MemorySize => Int]
- [Publish => Bool]
- [Tags => Paws::Lambda::Tags]
- [Timeout => Int]
- [TracingConfig => Paws::Lambda::TracingConfig]
- [VpcConfig => Paws::Lambda::VpcConfig]
Each argument is described in detail in: Paws::Lambda::CreateFunction
Returns: a Paws::Lambda::FunctionConfiguration instance
Creates a Lambda function. To create a function, you need a deployment package (https://docs.aws.amazon.com/lambda/latest/dg/deployment-package-v2.html) and an execution role (https://docs.aws.amazon.com/lambda/latest/dg/intro-permission-model.html#lambda-intro-execution-role). The deployment package contains your function code. The execution role grants the function permission to use AWS services, such as Amazon CloudWatch Logs for log streaming and AWS X-Ray for request tracing.
A function has an unpublished version, and can have published versions and aliases. The unpublished version changes when you update your function's code and configuration. A published version is a snapshot of your function code and configuration that can't be changed. An alias is a named resource that maps to a version, and can be changed to map to a different version. Use the Publish
parameter to create version 1
of your function from its initial configuration.
The other parameters let you configure version-specific and function-level settings. You can modify version-specific settings later with UpdateFunctionConfiguration. Function-level settings apply to both the unpublished and published versions of the function, and include tags (TagResource) and per-function concurrency limits (PutFunctionConcurrency).
If another account or an AWS service invokes your function, use AddPermission to grant permission by creating a resource-based IAM policy. You can grant permissions at the function level, on a version, or on an alias.
To invoke your function directly, use Invoke. To invoke your function in response to events in other AWS services, create an event source mapping (CreateEventSourceMapping), or configure a function trigger in the other service. For more information, see Invoking Functions (https://docs.aws.amazon.com/lambda/latest/dg/invoking-lambda-functions.html).
DeleteAlias
Each argument is described in detail in: Paws::Lambda::DeleteAlias
Returns: nothing
Deletes a Lambda function alias (https://docs.aws.amazon.com/lambda/latest/dg/versioning-aliases.html).
DeleteEventSourceMapping
Each argument is described in detail in: Paws::Lambda::DeleteEventSourceMapping
Returns: a Paws::Lambda::EventSourceMappingConfiguration instance
Deletes an event source mapping (https://docs.aws.amazon.com/lambda/latest/dg/intro-invocation-modes.html). You can get the identifier of a mapping from the output of ListEventSourceMappings.
DeleteFunction
Each argument is described in detail in: Paws::Lambda::DeleteFunction
Returns: nothing
Deletes a Lambda function. To delete a specific function version, use the Qualifier
parameter. Otherwise, all versions and aliases are deleted.
To delete Lambda event source mappings that invoke a function, use DeleteEventSourceMapping. For AWS services and resources that invoke your function directly, delete the trigger in the service where you originally configured it.
DeleteFunctionConcurrency
Each argument is described in detail in: Paws::Lambda::DeleteFunctionConcurrency
Returns: nothing
Removes a concurrent execution limit from a function.
DeleteLayerVersion
Each argument is described in detail in: Paws::Lambda::DeleteLayerVersion
Returns: nothing
Deletes a version of an AWS Lambda layer (https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html). Deleted versions can no longer be viewed or added to functions. To avoid breaking functions, a copy of the version remains in Lambda until no functions refer to it.
GetAccountSettings
Each argument is described in detail in: Paws::Lambda::GetAccountSettings

GetEventSourceMapping
Each argument is described in detail in: Paws::Lambda::GetEventSourceMapping
Returns: a Paws::Lambda::EventSourceMappingConfiguration instance
Returns details about an event source mapping. You can get the identifier of a mapping from the output of ListEventSourceMappings.
GetFunction
Each argument is described in detail in: Paws::Lambda::GetFunction
Returns: a Paws::Lambda::GetFunctionResponse instance
Returns information about the function or function version, with a link to download the deployment package that's valid for 10 minutes. If you specify a function version, only details that are specific to that version are returned.
GetFunctionConfiguration
Each argument is described in detail in: Paws::Lambda::GetFunctionConfiguration
Returns: a Paws::Lambda::FunctionConfiguration instance
Returns the version-specific settings of a Lambda function or version. The output includes only options that can vary between versions of a function. To modify these settings, use UpdateFunctionConfiguration.
To get all of a function's details, including function-level settings, use GetFunction.
GetLayerVersion
Each argument is described in detail in: Paws::Lambda::GetLayerVersion
Returns: a Paws::Lambda::GetLayerVersionResponse instance
Returns information about a version of an AWS Lambda layer (https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html), with a link to download the layer archive that's valid for 10 minutes.
GetLayerVersionByArn
Each argument is described in detail in: Paws::Lambda::GetLayerVersionByArn
Returns: a Paws::Lambda::GetLayerVersionResponse instance
Returns information about a version of an AWS Lambda layer (https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html), with a link to download the layer archive that's valid for 10 minutes.

Each argument is described in detail in: Paws::Lambda::GetPolicy
Returns: a Paws::Lambda::GetPolicyResponse instance
Returns the resource-based IAM policy (https://docs.aws.amazon.com/lambda/latest/dg/access-control-resource-based.html) for a function, version, or alias.
Invoke
- FunctionName => Str
- [ClientContext => Str]
- [InvocationType => Str]
- [LogType => Str]
- [Payload => Str]
- [Qualifier => Str]
Each argument is described in detail in: Paws::Lambda::Invoke
Returns: a Paws::Lambda::InvocationResponse instance
Invokes a Lambda function. You can invoke a function synchronously (and wait for the response), or asynchronously. To invoke a function asynchronously, set InvocationType
to Event
.
For synchronous invocation, details about the function response, including errors, are included in the response body and headers. For either invocation type, you can find more information in the execution log (https://docs.aws.amazon.com/lambda/latest/dg/monitoring-functions.html) and trace (https://docs.aws.amazon.com/lambda/latest/dg/dlq.html). To record function errors for asynchronous invocations, configure your function with a dead letter queue (https://docs.aws.amazon.com/lambda/latest/dg/dlq.html).
When an error occurs, your function may be invoked multiple times. Retry behavior varies by error type, client, event source, and invocation type. For example, if you invoke a function asynchronously and it returns an error, Lambda executes the function up to two more times. For more information, see Retry Behavior (https://docs.aws.amazon.com/lambda/latest/dg/retries-on-errors.html).
The status code in the API response doesn't reflect function errors. Error codes are reserved for errors that prevent your function from executing, such as permissions errors, limit errors (https://docs.aws.amazon.com/lambda/latest/dg/limits.html), or issues with your function's code and configuration. For example, Lambda returns TooManyRequestsException
if executing the function would cause you to exceed a concurrency limit at either the account level (ConcurrentInvocationLimitExceeded
) or function level (ReservedFunctionConcurrentInvocationLimitExceeded
).
For functions with a long timeout, your client might be disconnected during synchronous invocation while it waits for a response. Configure your HTTP client, SDK, firewall, proxy, or operating system to allow for long connections with timeout or keep-alive settings.
This operation requires permission for the lambda:InvokeFunction
action.

Each argument is described in detail in: Paws::Lambda::InvokeAsync
Returns: a Paws::Lambda::InvokeAsyncResponse instance
For asynchronous function invocation, use Invoke.
Invokes a function asynchronously.
ListAliases
Each argument is described in detail in: Paws::Lambda::ListAliases

to only show event source mappings for a single event source.
ListFunctions
Each argument is described in detail in: Paws::Lambda::ListFunctions
Returns: a Paws::Lambda::ListFunctionsResponse instance
Returns a list of Lambda functions, with the version-specific configuration of each.
Set FunctionVersion
to ALL

Each argument is described in detail in: Paws::Lambda::ListLayerVersions
Returns: a Paws::Lambda::ListLayerVersionsResponse instance
Lists the versions of an AWS Lambda layer (https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html). Versions that have been deleted aren't listed. Specify a runtime identifier (https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html) to list only versions that indicate that they're compatible with that runtime.
ListTags
Each argument is described in detail in: Paws::Lambda::ListTags
Returns: a Paws::Lambda::ListTagsResponse instance
Returns a function's tags (https://docs.aws.amazon.com/lambda/latest/dg/tagging.html). You can also view tags with GetFunction.
ListVersionsByFunction
Each argument is described in detail in: Paws::Lambda::ListVersionsByFunction

- LayerName => Str
- [CompatibleRuntimes => ArrayRef[Str|Undef]]
- [Description => Str]
- [LicenseInfo => Str]
Each argument is described in detail in: Paws::Lambda::PublishLayerVersion
Returns: a Paws::Lambda::PublishLayerVersionResponse instance
Creates an AWS Lambda layer (https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html) from a ZIP archive. Each time you call PublishLayerVersion
with the same version name, a new version is created.
Add layers to your function with CreateFunction or UpdateFunctionConfiguration.
PublishVersion
Each argument is described in detail in: Paws::Lambda::PublishVersion
Returns: a Paws::Lambda::FunctionConfiguration instance
Creates a version (https://docs.aws.amazon.com/lambda/latest/dg/versioning-aliases.html) from the current code and configuration of a function. Use versions to create a snapshot of your function code and configuration that doesn't change.
AWS Lambda doesn't publish a version if the function's configuration and code haven't changed since the last version. Use UpdateFunctionCode or UpdateFunctionConfiguration to update the function before publishing a version.
Clients can invoke versions directly or with an alias. To create an alias, use CreateAlias.
PutFunctionConcurrency
Each argument is described in detail in: Paws::Lambda::PutFunctionConcurrency
Returns: a Paws::Lambda::Concurrency instance
Sets the maximum number of simultaneous executions for a function, and reserves capacity for that concurrency level.
Concurrency settings apply to the function as a whole, including all published versions and the unpublished version. Reserving concurrency both ensures that your function has capacity to process the specified number of events simultaneously, and prevents it from scaling beyond that level. Use GetFunction to see the current setting for a function.
Use GetAccountSettings to see your regional concurrency limit. You can reserve concurrency for as many functions as you like, as long as you leave at least 100 simultaneous executions unreserved for functions that aren't configured with a per-function limit. For more information, see Managing Concurrency (https://docs.aws.amazon.com/lambda/latest/dg/concurrent-executions.html).
RemoveLayerVersionPermission
Each argument is described in detail in: Paws::Lambda::RemoveLayerVersionPermission
