AddLayerVersionPermission

$result = $client->addLayerVersionPermission([/* ... */]);
$promise = $client->addLayerVersionPermissionAsync([/* ... */]);

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.

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',

CreateEventSourceMapping

$result = $client->createEventSourceMapping([/* ... */]);
$promise = $client->createEventSourceMappingAsync([/* ... */]);

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.

• Amazon DynamoDB Streams

• Amazon Kinesis

• Amazon SQS

• Amazon MQ and RabbitMQ

• Amazon MSK

• Apache Kafka

• Amazon DocumentDB

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.

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',

]

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.

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
