AWS Lambda 2015-03-31
- Client: Aws\Lambda\LambdaClient
- Service ID: lambda
- Version: 2015-03-31
This page describes the parameters and results for the operations of the AWS Lambda (2015-03-31), and shows how to use the Aws\Lambda\LambdaClient object to call the described operations. This documentation is specific to the 2015-03-31 API version of the service.
Operation Summary
Each of the following operations can be created from a client using
$client->getCommand('CommandName')
, where "CommandName" is the
name of one of the following operations. Note: a command is a value that
encapsulates an operation and the parameters used to create an HTTP request.
You can also create and send a command immediately using the magic methods
available on a client object: $client->commandName(/* parameters */)
.
You can send the command asynchronously (returning a promise) by appending the
word "Async" to the operation name: $client->commandNameAsync(/* parameters */)

Examples
Example 1: To add permissions to a layer version
The following example grants permission for the account 223456789012 to use version 1 of a layer named my-layer.
$result = $client->addLayerVersionPermission([ 'Action' => 'lambda:GetLayerVersion', 'LayerName' => 'my-layer', 'Principal' => '223456789012', 'StatementId' => 'xaccount', 'VersionNumber' => 1, ]);
Result syntax:
[ 'RevisionId' => '35d87451-f796-4a3f-a618-95a3671b0a0c', 'Statement' => '{"Sid":"xaccount","Effect":"Allow","Principal":{"AWS":"arn:aws:iam::223456789012:root"},"Action":"lambda:GetLayerVersion","Resource":"arn:aws:lambda:us-east-2:123456789012:layer:my-layer:1"}', ]
AddPermission
$result = $client->addPermission
([/* ... */]); $promise = $client->addPermissionAsync
([/* ... */]);
Grants a principal 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 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 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.
Parameter Syntax
$result = $client->addPermission([ 'Action' => '<string>', // REQUIRED 'EventSourceToken' => '<string>', 'FunctionName' => '<string>', // REQUIRED 'FunctionUrlAuthType' => 'NONE|AWS_IAM', 'Principal' => '<string>', // REQUIRED 'PrincipalOrgID' => '<string>', 'Qualifier' => '<string>', 'RevisionId' => '<string>', 'SourceAccount' => '<string>', 'SourceArn' => '<string>', 'StatementId' => '<string>', // REQUIRED ]);

Examples
Example 1: To create a mapping between an event source and an AWS Lambda function
The following example creates a mapping between an SQS queue and the my-function Lambda function.
$result = $client->createEventSourceMapping([ 'BatchSize' => 5, 'EventSourceArn' => 'arn:aws:sqs:us-west-2:123456789012:my-queue', 'FunctionName' => 'my-function', ]);
Result syntax:
[ 'BatchSize' => 5, 'EventSourceArn' => 'arn:aws:sqs:us-west-2:123456789012:my-queue', 'FunctionArn' => 'arn:aws:lambda:us-west-2:123456789012:function:my-function', 'LastModified' =>, 'State' => 'Creating', 'StateTransitionReason' => 'USER_INITIATED', 'UUID' => 'a1b2c3d4-5678-90ab-cdef-11111EXAMPLE', ]
CreateFunction
$result = $client->createFunction
([/* ... */]); $promise = $client->createFunctionAsync
([/* ... */]);
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 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 Services 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 services, create an event source mapping (CreateEventSourceMapping), or configure a function trigger in the other service. For more information, see Invoking Lambda functions.

to at least 1. - MaximumRecordAgeInSeconds
-
- Type: int
(Kinesis and DynamoDB Streams only) Discard records older than the specified age. The default value is -1, which sets the maximum age to infinite. When the value is set to infinite, Lambda never discards old records.
The minimum valid value for maximum record age is 60s. Although values less than 60 and greater than -1 fall within the parameter's absolute range, they are not allowed
- MaximumRetryAttempts
-
- Type: int
(Kinesis and DynamoDB Streams only) Discard records after the specified number of retries. The default value is -1, which sets the maximum number of retries to infinite. When MaximumRetryAttempts is infinite, Lambda retries failed records until the record expires in the event source.

- BatchSize
-
- Type: int
The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).
Default value: Varies by service. For Amazon SQS, the default is 10. For all other services, the default is 100.
Related setting: When you set
BatchSize
to a value greater than 10, you must setMaximumBatchingWindowInSeconds
to at least 1. - BisectBatchOnFunctionError
-
- Type: boolean
(Kinesis and DynamoDB Streams only) If the function returns an error, split the batch in two and retry. The default value is false.

An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering.
If filter criteria is encrypted, this field shows up as
null
in the response of ListEventSourceMapping API calls. You can view this field in plaintext in the response of GetEventSourceMapping and DeleteEventSourceMapping calls if you havekms:Decrypt
permissions for the correct KMS key. - FilterCriteriaError

-
- Type: int
The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure
MaximumBatchingWindowInSeconds
to any value from 0 seconds to 300 seconds in increments of seconds.For streams and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, Amazon MQ, and DocumentDB event sources, the default batching window is 500 ms. Note that because you can only change
MaximumBatchingWindowInSeconds
in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.Related setting: For streams and Amazon SQS event sources, when you set
BatchSize
to a value greater than 10, you must setMaximumBatchingWindowInSeconds
to at least 1. - MaximumRecordAgeInSeconds
-
- Type: int
(Kinesis and DynamoDB Streams only) Discard records older than the specified age. The default value is -1, which sets the maximum age to infinite. When the value is set to infinite, Lambda never discards old records.
The minimum valid value for maximum record age is 60s. Although values less than 60 and greater than -1 fall within the parameter's absolute range, they are not allowed
- MaximumRetryAttempts
-
- Type: int
(Kinesis and DynamoDB Streams only) Discard records after the specified number of retries. The default value is -1, which sets the maximum number of retries to infinite. When MaximumRetryAttempts is infinite, Lambda retries failed records until the record expires in the event source.

Invoke
$result = $client->invoke
([/* ... */]); $promise = $client->invokeAsync
([/* ... */]);
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.
Parameter Syntax
$result = $client->invoke([ 'ClientContext' => '<string>', 'FunctionName' => '<string>', // REQUIRED 'InvocationType' => 'Event|RequestResponse|DryRun', 'LogType' => 'None|Tail', 'Payload' => <string || resource || Psr\Http\Message\StreamInterface>, 'Qualifier' => '<string>', ]);

PutFunctionConcurrency
$result = $client->putFunctionConcurrency
([/* ... */]); $promise = $client->putFunctionConcurrencyAsync
([/* ... */]);
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.

[ 'ReservedConcurrentExecutions' => 100, ]
PutFunctionEventInvokeConfig
$result = $client->putFunctionEventInvokeConfig
([/* ... */]); $promise = $client->putFunctionEventInvokeConfigAsync
([/* ... */]);
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.
Parameter Syntax
$result = $client->putFunctionEventInvokeConfig([ 'DestinationConfig' => [ 'OnFailure' => [ 'Destination' => '<string>', ], 'OnSuccess' => [ 'Destination' => '<string>', ], ], 'FunctionName' => '<string>', // REQUIRED 'MaximumEventAgeInSeconds' => <integer>, 'MaximumRetryAttempts' => <integer>, 'Qualifier' => '<string>', ]);

PutFunctionRecursionConfig
$result = $client->putFunctionRecursionConfig
([/* ... */]); $promise = $client->putFunctionRecursionConfigAsync
([/* ... */]);
Sets your function's recursive loop detection configuration.
When you configure a Lambda function to output to the same service or resource that invokes the function, it's possible to create an infinite recursive loop. For example, a Lambda function might write a message to an Amazon Simple Queue Service (Amazon SQS) queue, which then invokes the same function. This invocation causes the function to write another message to the queue, which in turn invokes the function again.
Lambda can detect certain types of recursive loops shortly after they occur. When Lambda detects a recursive loop and your function's recursive loop detection configuration is set to Terminate
, it stops your function being invoked and notifies you.
Parameter Syntax
$result = $client->putFunctionRecursionConfig([ 'FunctionName' => '<string>', // REQUIRED 'RecursiveLoop' => 'Allow|Terminate', // REQUIRED ]);

Auto (default) - Automatically update to the most recent and secure runtime version using a Two-phase runtime version rollout. This is the best choice for most customers to ensure they always benefit from runtime updates.
-
Function update - Lambda updates the runtime of your function to the most recent and secure runtime version when you update your function. This approach synchronizes runtime updates with function deployments, giving you control over when runtime updates are applied and allowing you to detect and mitigate rare runtime update incompatibilities early. When using this setting, you need to regularly update your functions to keep their runtime up-to-date.
-
Manual - You specify a runtime version in your function configuration. The function will use this runtime version indefinitely. In the rare case where a new runtime version is incompatible with an existing function, this allows you to roll back your function to an earlier runtime version.

Examples
Example 1: To update a Lambda function event source mapping
This operation updates a Lambda function event source mapping
$result = $client->updateEventSourceMapping([ 'BatchSize' => 123, 'Enabled' => 1, 'FunctionName' => 'myFunction', 'UUID' => '1234xCy789012', ]);
Result syntax:
[ 'BatchSize' => 123, 'EventSourceArn' => 'arn:aws:s3:::examplebucket/*', 'FunctionArn' => 'arn:aws:lambda:us-west-2:123456789012:function:myFunction', 'LastModified' =>, 'LastProcessingResult' => '', 'State' => '', 'StateTransitionReason' => '', 'UUID' => '1234xCy789012', ]
UpdateFunctionCode
$result = $client->updateFunctionCode
([/* ... */]); $promise = $client->updateFunctionCodeAsync
([/* ... */]);
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.

Examples
Example 1: To update a Lambda function's code
The following example replaces the code of the unpublished ($LATEST) version of a function named my-function with the contents of the specified zip file in Amazon S3.
$result = $client->updateFunctionCode([ 'FunctionName' => 'my-function', 'S3Bucket' => 'my-bucket-1xpuxmplzrlbh', 'S3Key' => 'function.zip', ]);
Result syntax:
[ 'CodeSha256' => 'PFn4S+er27qk+UuZSTKEQfNKG/XNn7QJs90mJgq6oH8=', 'CodeSize' => 308, 'Description' => '', 'FunctionArn' => 'arn:aws:lambda:us-east-2:123456789012:function:my-function', 'FunctionName' => 'my-function', 'Handler' => 'index.handler', 'LastModified' => '2019-08-14T22:26:11.234+0000', 'MemorySize' => 128, 'RevisionId' => '873282ed-xmpl-4dc8-a069-d0c647e470c6', 'Role' => 'arn:aws:iam::123456789012:role/lambda-role', 'Runtime' => 'nodejs12.x', 'Timeout' => 3, 'TracingConfig' => [ 'Mode' => 'PassThrough', ], 'Version' => '$LATEST', ]
UpdateFunctionConfiguration
$result = $client->updateFunctionConfiguration
([/* ... */]); $promise = $client->updateFunctionConfigurationAsync
([/* ... */]);
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 Services service, use AddPermission.
