Lambda
overview
Overview
Lambda is a compute service that lets you run code without provisioning or managing servers.
Lambda runs your code on a high-availability compute infrastructure and performs all of the administration of the compute resources, including server and operating system maintenance, capacity provisioning and automatic scaling, code monitoring and logging. With Lambda, you can run code for virtually any type of application or backend service. For more information about the Lambda service, see What is Lambda in the Lambda Developer Guide.
The Lambda API Reference provides information about each of the API methods, including details about the parameters in each API request and response.
You can use Software Development Kits (SDKs), Integrated Development Environment (IDE) Toolkits, and command line tools to access the API. For installation instructions, see Tools for Amazon Web Services.
For a list of Region-specific endpoints that Lambda supports, see Lambda endpoints and quotas in the Amazon Web Services General Reference..
When making the API calls, you will need to authenticate your request by providing a signature. Lambda supports signature version 4. For more information, see Signature Version 4 signing process in the Amazon Web Services General Reference..
ca-certificates
CA certificates
Because Amazon Web Services SDKs use the CA certificates from your computer, changes to the certificates on the Amazon Web Services servers can cause connection failures when you attempt to use an SDK. You can prevent these failures by keeping your computer's CA certificates and operating system up-to-date. If you encounter this issue in a corporate environment and do not manage your own computer, you might need to ask an administrator to assist with the update process. The following list shows minimum operating system and Java versions:
Microsoft Windows versions that have updates from January 2005 or later installed contain at least one of the required CAs in their trust list.
Mac OS X 10.4 with Java for Mac OS X 10.4 Release 5 (February 2007), Mac OS X 10.5 (October 2007), and later versions contain at least one of the required CAs in their trust list.
Red Hat Enterprise Linux 5 (March 2007), 6, and 7 and CentOS 5, 6, and 7 all contain at least one of the required CAs in their default trusted CA list.
Java 1.4.2_12 (May 2006), 5 Update 2 (March 2005), and all later versions, including Java 6 (December 2006), 7, and 8, contain at least one of the required CAs in their default trusted CA list.
When accessing the Lambda management console or Lambda API endpoints, whether through browsers or programmatically, you will need to ensure your client machines support any of the following CAs:
Amazon Root CA 1
Starfield Services Root Certificate Authority - G2
Starfield Class 2 Certification Authority
Root certificates from the first two authorities are available from Amazon trust services, but keeping your computer up-to-date is the more straightforward solution. To learn more about ACM-provided certificates, see Amazon Web Services Certificate Manager FAQs.

add_layer_version_permission(client, layer_name, version_number, input, options \\ [])
View SourceAdds permissions to the resource-based policy of a version of an Lambda layer.
Use this action to grant layer usage permission to other accounts. You can grant permission to a single account, all accounts in an organization, or all Amazon Web Services accounts.
To revoke permission, call RemoveLayerVersionPermission
with the statement ID
that you specified when you added it.
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.
Creates an alias 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.
Creates a code signing configuration.
A code signing configuration defines a list of allowed signing profiles and defines the code-signing validation policy (action to be taken if deployment validation checks fail).
Creates a mapping between an event source and an Lambda function.
Lambda reads items from the event source and invokes the function.
For details about how to configure different event sources, see the following topics.
The following error handling options are available only for stream sources (DynamoDB and Kinesis):
BisectBatchOnFunctionError
– If the function returns an error, split the batch in two and retry.DestinationConfig
– Send discarded records to an Amazon SQS queue or Amazon SNS topic.MaximumRecordAgeInSeconds
– Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expiresMaximumRetryAttempts
– Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.ParallelizationFactor
– Process multiple batches from each shard concurrently.
For information about which configuration parameters apply to each event source, see the following topics.
Creates a Lambda function.
To create a function, you need a deployment package and an execution role. The deployment package is a .zip file archive or container image that contains your function code. The execution role grants the function permission to use Amazon Web Services, such as Amazon CloudWatch Logs for log streaming and X-Ray for request tracing.
If the deployment package is a container image, then
you set the package type to Image
. For a container image, the code property
must include the URI of a container image in the Amazon ECR registry. You do not
need to specify the handler and runtime properties.
If the deployment package is a .zip file archive,
then you set the package type to Zip
. For a .zip file archive, the code
property specifies the location of the .zip file. You must also specify the
handler and runtime properties. The code in the deployment package must be
compatible with the target instruction set architecture of the function
(x86-64
or arm64
). If you do not specify the architecture, then the default
value is x86-64
.
When you create a function, Lambda provisions an instance of the function and
its supporting resources. If your function connects to a VPC, this process can
take a minute or so. During this time, you can't invoke or modify the function.
The State
, StateReason
, and StateReasonCode
fields in the response from
GetFunctionConfiguration
indicate when the function is ready to invoke. For
more information, see Lambda function states.
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
).
You can use code signing if your deployment package is a .zip file archive. To
enable code signing for this function, specify the ARN of a code-signing
configuration. When a user attempts to deploy a code package with
UpdateFunctionCode
, Lambda checks that the code package has a valid signature
from a trusted publisher. The code-signing configuration includes set of signing
profiles, which define the trusted publishers for this function.
If another Amazon Web Services account or an Amazon Web Service invokes your
function, use AddPermission
to grant permission by creating a resource-based
Identity and Access Management (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 Amazon Web Services, create an event source mapping
(CreateEventSourceMapping
), or configure a function trigger in the other
service. For more information, see Invoking Lambda functions.
create_function_url_config(client, function_name, input, options \\ [])
View SourceCreates a Lambda function URL with the specified configuration parameters.

version and the runtime update mode. If the runtime update mode is Auto or
Function update, this includes the runtime update mode and null
is
returned for the ARN. For more information, see Runtime updates.
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 and trace. 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 Error handling and automatic retries in Lambda.
For asynchronous invocation, Lambda adds events to a queue before sending them to your function. If your function does not have enough capacity to keep up with the queue, events may be lost. Occasionally, your function may receive the same event multiple times, even if no error occurs. To retain events that were not processed, configure your function with a dead-letter queue.
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,
quota errors, or issues with your function's code and configuration. For example,
Lambda returns TooManyRequestsException
if running 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 disconnect 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. For details on how to set up permissions for cross-account invocations, see Granting function access to other accounts.
For asynchronous function invocation, use Invoke
.

Creates an Lambda layer from a ZIP archive.
Each time you call PublishLayerVersion
with the same layer name, a new version
is created.
Add layers to your function with CreateFunction
or
UpdateFunctionConfiguration
.
Creates a version 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.
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
.
put_function_code_signing_config(client, function_name, input, options \\ [])
View SourceUpdate the code signing configuration for the function.
Changes to the code signing configuration take effect the next time a user tries to deploy a code package to the function.
put_function_concurrency(client, function_name, input, options \\ [])
View SourceSets 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 Lambda function scaling.
put_function_event_invoke_config(client, function_name, input, options \\ [])
View SourceConfigures options for asynchronous invocation on a function, version, or alias.
If a configuration already exists for a function, version, or alias, this
operation overwrites it. If you exclude any settings, they are removed. To set
one option without affecting existing settings for other options, use
UpdateFunctionEventInvokeConfig
.
By default, Lambda retries an asynchronous invocation twice if the function
returns an error. It retains events in a queue for up to six hours. When an
event fails all processing attempts or stays in the asynchronous invocation
queue for too long, Lambda discards it. To retain discarded events, configure a
dead-letter queue with UpdateFunctionConfiguration
.
To send an invocation record to a queue, topic, function, or event bus, specify a destination. You can configure separate destinations for successful invocations (on-success) and events that fail all processing attempts (on-failure). You can configure destinations in addition to or instead of a dead-letter queue.
put_provisioned_concurrency_config(client, function_name, input, options \\ [])
View SourceAdds a provisioned concurrency configuration to a function's alias or version.
put_runtime_management_config(client, function_name, input, options \\ [])

You can change the function that Lambda invokes, or pause invocation and resume later from the same location.
For details about how to configure different event sources, see the following topics.
The following error handling options are available only for stream sources (DynamoDB and Kinesis):
BisectBatchOnFunctionError
– If the function returns an error, split the batch in two and retry.DestinationConfig
– Send discarded records to an Amazon SQS queue or Amazon SNS topic.MaximumRecordAgeInSeconds
– Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expiresMaximumRetryAttempts
– Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.ParallelizationFactor
– Process multiple batches from each shard concurrently.
For information about which configuration parameters apply to each event source, see the following topics.
Updates a Lambda function's code.
If code signing is enabled for the function, the code package must be signed by a trusted publisher. For more information, see Configuring code signing for Lambda.
If the function's package type is Image
, then you must specify the code
package in ImageUri
as the URI of a container image in the
Amazon ECR registry.
If the function's package type is Zip
, then you must specify the deployment
package as a .zip file archive.
Enter the Amazon S3 bucket and key of the code .zip file location. You can also
provide the function code inline using the ZipFile
field.
The code in the deployment package must be compatible with the target
instruction set architecture of the function (x86-64
or arm64
).
The function's code is locked when you publish a version. You can't modify the code of a published version, only the unpublished version.
For a function defined as a container image, Lambda resolves the image tag to an image digest. In Amazon ECR, if you update the image tag to a new image, Lambda does not automatically update the function.
update_function_configuration(client, function_name, input, options \\ [])
View SourceModify the version-specific settings of a Lambda function.
When you update a function, Lambda provisions an instance of the function and
its supporting resources. If your function connects to a VPC, this process can
take a minute. During this time, you can't modify the function, but you can
still invoke it. The LastUpdateStatus
, LastUpdateStatusReason
, and
LastUpdateStatusReasonCode
fields in the response from
GetFunctionConfiguration
indicate when the update is complete and the function
is processing events with the new configuration. For more information, see
Lambda function states.
These settings can vary between versions of a function and are locked when you publish a version. You can't modify the configuration of a published version, only the unpublished version.
To configure function concurrency, use PutFunctionConcurrency
. To grant invoke
permissions to an Amazon Web Services account or Amazon Web Service, use
AddPermission
.
update_function_event_invoke_config(client, function_name, input, options \\ [])
View SourceUpdates the configuration for asynchronous invocation for a function, version, or alias.
To configure options for asynchronous invocation, use
