Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Overview

This is the Lambda API Reference. The Lambda Developer Guide provides additional information. For the service overview, see What is Lambda, and for information about how the service works, see Lambda: How it Works in the Lambda Developer Guide.

Sending a Request Using Lambda

var lambda = new AWS.Lambda();
lambda.addLayerVersionPermission(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the Lambda object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var lambda = new AWS.Lambda({apiVersion: '2015-03-31'});

You can also set the API version globally in AWS.config.apiVersions using the lambda service identifier:

AWS.config.apiVersions = {
  lambda: '2015-03-31',
  // other service API versions
};

var lambda = new AWS.Lambda();

Version:

  • 2015-03-31

Waiter Resource States

This service supports a list of resource states that can be polled using the waitFor() method. The resource states are:

functionExists, functionActive, functionUpdated

Method Details

addLayerVersionPermission(params = {}, callback) ⇒ AWS.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.

Service Reference:

Examples:

Calling the addLayerVersionPermission operation

var params = {
  Action: 'STRING_VALUE', /* required */
  LayerName: 'STRING_VALUE', /* required */
  Principal: 'STRING_VALUE', /* required */
  StatementId: 'STRING_VALUE', /* required */
  VersionNumber: 'NUMBER_VALUE', /* required */
  OrganizationId: 'STRING_VALUE',
  RevisionId: 'STRING_VALUE'
};
lambda.addLayerVersionPermission(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • LayerName — (String)

      The name or Amazon Resource Name (ARN) of the layer.

    • VersionNumber — (Integer)

      The version number.

    • StatementId — (String)

      An identifier that distinguishes the policy from others on the same layer version.

    • Action — (String)

      The API action that grants access to the layer. For example, lambda:GetLayerVersion.

    • Principal — (String)

      An account ID, or * to grant layer usage permission to all accounts in an organization, or all Amazon Web Services accounts (if organizationId is not specified). For the last case, make sure that you really do want all Amazon Web Services accounts to have usage permission to this layer.

    • OrganizationId — (String)

      With the principal set to *, grant permission to all accounts in the specified organization.

    • RevisionId — (String)

      Only update the policy if the revision ID matches the ID specified. Use this option to avoid modifying a policy that has changed since you last read it.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • Statement — (String)

        The permission statement.

      • RevisionId — (String)

        A unique identifier for the current revision of the policy.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

addPermission(params = {}, callback) ⇒ AWS.Request

Grants an Amazon Web Services 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. Note: Lambda does not support adding policies to version $LATEST.

To grant permission to another account, specify the account ID as the Principal. For Amazon Web Services services, the principal is a domain-style identifier defined by the service, like 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 action adds a statement to a resource-based permissions policy for the function. For more information about function policies, see Lambda Function Policies.

Service Reference:

Examples:

Calling the addPermission operation

var params = {
  Action: 'STRING_VALUE', /* required */
  FunctionName: 'STRING_VALUE', /* required */
  Principal: 'STRING_VALUE', /* required */
  StatementId: 'STRING_VALUE', /* required */
  EventSourceToken: 'STRING_VALUE',
  Qualifier: 'STRING_VALUE',

createFunction(params = {}, callback) ⇒ AWS.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 services, such as Amazon CloudWatch Logs for log streaming and X-Ray for request tracing.

You set the package type to Image if the deployment package is a container 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.

You set the package type to Zip if the deployment package is a .zip file archive. 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, 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 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 set of signing profiles, which define the trusted publishers for this function.

If another account or an Amazon Web Services 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 Amazon Web Services services, create an event source mapping (CreateEventSourceMapping), or configure a function trigger in the other service. For more information, see Invoking Functions.

invoke(params = {}, callback) ⇒ AWS.Request

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 Retry Behavior.

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, limit errors, 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.

Service Reference:

Examples:

Calling the invoke operation

var params = {
  FunctionName: 'STRING_VALUE', /* required */
  ClientContext: 'STRING_VALUE',
  InvocationType: Event | RequestResponse | DryRun,
  LogType: None | Tail,
  Payload: Buffer.from('...') || 'STRING_VALUE' /* Strings will be Base-64 encoded on your behalf */,
  Qualifier: 'STRING_VALUE'
};
lambda.invoke(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • FunctionName — (String)

      The name of the Lambda function, version, or alias.

      Name formats

      • Function name - my-function (name-only), my-function:v1 (with alias).

Clients can invoke versions directly or with an alias. To create an alias, use CreateAlias.

Service Reference:

Examples:

Calling the publishVersion operation

var params = {
  FunctionName: 'STRING_VALUE', /* required */
  CodeSha256: 'STRING_VALUE',

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.

};
lambda.putFunctionConcurrency(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • FunctionName — (String)

      The name of the Lambda function.

      Name formats

      • Function name - my-function.

      • Function ARN - arn:aws:lambda:us-west-2:123456789012:function:my-function.

      • Partial ARN - 123456789012:function:my-function.

      The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

    • ReservedConcurrentExecutions — (Integer)

      The number of simultaneous executions to reserve for the function.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

putFunctionEventInvokeConfig(params = {}, callback) ⇒ AWS.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.

Examples:

Calling the putFunctionEventInvokeConfig operation

var params = {
  FunctionName: 'STRING_VALUE', /* required */

updateFunctionCode(params = {}, callback) ⇒ AWS.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.

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.

Note: 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.

Service Reference:

Examples:

Calling the updateFunctionCode operation

var params = {
  FunctionName: 'STRING_VALUE', /* required */
  Architectures: [
    x86_64 | arm64,
    /* more items */
  ],
  DryRun: true || false,
  ImageUri: 'STRING_VALUE',
  Publish: true || false,
  RevisionId: 'STRING_VALUE',
  S3Bucket: 'STRING_VALUE',
  S3Key: 'STRING_VALUE',
  S3ObjectVersion: 'STRING_VALUE',
  ZipFile: Buffer.from('...') || 'STRING_VALUE' /* Strings will be Base-64 encoded on your behalf */
};
lambda.updateFunctionCode(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

updateFunctionConfiguration(params = {}, callback) ⇒ AWS.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 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 account or Amazon Web Services service, use AddPermission.
