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
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.

public AddLayerVersionPermissionResult addLayerVersionPermission(AddLayerVersionPermissionRequest request)
Adds 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.
addLayerVersionPermission in interface AWSLambdaaddLayerVersionPermissionRequest - ServiceException - The Lambda service encountered an internal error.ResourceNotFoundException - The resource specified in the request does not exist.ResourceConflictException - The resource already exists, or another operation is in progress.TooManyRequestsException - The request throughput limit was exceeded. For more information, see Lambda
quotas.InvalidParameterValueException - One of the parameters in the request is not valid.PolicyLengthExceededException - The permissions policy for the resource is too large. For more information, see Lambda quotas.PreconditionFailedException - The RevisionId provided does not match the latest RevisionId for the Lambda function or alias. Call the
GetFunction or the GetAlias API operation to retrieve the latest RevisionId for
your resource.public AddPermissionResult addPermission(AddPermissionRequest request)
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.

AddPermissionResult response = client.addPermission(request);public CreateAliasResult createAlias(CreateAliasRequest request)
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.

For more information, see Lambda
quotas.public CreateCodeSigningConfigResult createCodeSigningConfig(CreateCodeSigningConfigRequest request)
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).
createCodeSigningConfig in interface AWSLambdacreateCodeSigningConfigRequest - ServiceException - The Lambda service encountered an internal error.InvalidParameterValueException - One of the parameters in the request is not valid.public CreateEventSourceMappingResult createEventSourceMapping(CreateEventSourceMappingRequest request)
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 expires
MaximumRetryAttempts – 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.
createEventSourceMapping in interface AWSLambdacreateEventSourceMappingRequest - ServiceException - The Lambda service encountered an internal error.InvalidParameterValueException - One of the parameters in the request is not valid.ResourceConflictException - The resource already exists, or another operation is in progress.TooManyRequestsException - The request throughput limit was exceeded. For more information, see Lambda
quotas.ResourceNotFoundException - The resource specified in the request does not exist.public CreateFunctionResult createFunction(CreateFunctionRequest request)
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.

quotas.public InvokeResult invoke(InvokeRequest request)
Invokes a Lambda function. You can invoke a function synchronously (and wait for the response), or
asynchronously. By default, Lambda invokes your function synchronously (i.e. theInvocationType is
RequestResponse). To invoke a function asynchronously, set InvocationType to
Event. Lambda passes the ClientContext object to your function for synchronous
invocations only.
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.

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 Lambda function scaling.

For more information, see Lambda
quotas.ResourceConflictException - The resource already exists, or another operation is in progress.public PutFunctionEventInvokeConfigResult putFunctionEventInvokeConfig(PutFunctionEventInvokeConfigRequest request)
Configures 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.

Updates an event source mapping. 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 expires
MaximumRetryAttempts – 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.

UpdateEventSourceMappingResult response = client.updateEventSourceMapping(request);public UpdateFunctionCodeResult updateFunctionCode(UpdateFunctionCodeRequest request)
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.

UpdateFunctionCodeResult response = client.updateFunctionCode(request);public UpdateFunctionConfigurationResult updateFunctionConfiguration(UpdateFunctionConfigurationRequest request)
Modify 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.
