### 2018-10-31
| Method | Path | Description |
|--------|------|-------------|
| POST | /2018-10-31/layers/{LayerName}/versions/{VersionNumber}/policy | 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. |
| DELETE | /2018-10-31/layers/{LayerName}/versions/{VersionNumber} | Deletes a version of an Lambda layer. Deleted versions can no longer be viewed or added to functions. To avoid breaking functions, a copy of the version remains in Lambda until no functions refer to it. |
| GET | /2018-10-31/layers/{LayerName}/versions/{VersionNumber} | Returns information about a version of an Lambda layer, with a link to download the layer archive that's valid for 10 minutes. |
| GET | /2018-10-31/layers?find=LayerVersion | Returns information about a version of an Lambda layer, with a link to download the layer archive that's valid for 10 minutes. |
| GET | /2018-10-31/layers/{LayerName}/versions/{VersionNumber}/policy | Returns the permission policy for a version of an Lambda layer. For more information, see AddLayerVersionPermission. |
| GET | /2018-10-31/layers/{LayerName}/versions | Lists the versions of an Lambda layer. Versions that have been deleted aren't listed. Specify a runtime identifier to list only versions that indicate that they're compatible with that runtime. Specify a compatible architecture to include only layer versions that are compatible with that architecture. |
| GET | /2018-10-31/layers | Lists Lambda layers and shows information about the latest version of each. Specify a runtime identifier to list only layers that indicate that they're compatible with that runtime. Specify a compatible architecture to include only layers that are compatible with that instruction set architecture. |
| POST | /2018-10-31/layers/{LayerName}/versions | 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. |
| DELETE | /2018-10-31/layers/{LayerName}/versions/{VersionNumber}/policy/{StatementId} | Removes a statement from the permissions policy for a version of an Lambda layer. For more information, see AddLayerVersionPermission. |

### 2015-03-31
| Method | Path | Description |
|--------|------|-------------|
| POST | /2015-03-31/functions/{FunctionName}/policy | Grants an Amazon Web Servicesservice, 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 Servicesservices, the principal is a domain-style identifier that the service defines, such as s3.amazonaws.com or sns.amazonaws.com. For Amazon Web Servicesservices, 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. |
| POST | /2015-03-31/functions/{FunctionName}/aliases | 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. |
| POST | /2015-03-31/event-source-mappings/ | 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.

| POST | /2015-03-31/functions | 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 Servicesservices, 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 Servicesservice 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 Servicesservices, create an event source mapping (CreateEventSourceMapping), or configure a function trigger in the other service. For more information, see Invoking Lambda functions. |
| DELETE | /2015-03-31/functions/{FunctionName}/aliases/{Name} | Deletes a Lambda function alias. |
| DELETE | /2015-03-31/event-source-mappings/{UUID} | Deletes an event source mapping. You can get the identifier of a mapping from the output of ListEventSourceMappings. When you delete an event source mapping, it enters a Deleting state and might not be completely deleted for several seconds. |
| DELETE | /2015-03-31/functions/{FunctionName} | Deletes a Lambda function. To delete a specific function version, use the Qualifier parameter. Otherwise, all versions and aliases are deleted. This doesn't require the user to have explicit permissions for DeleteAlias. To delete Lambda event source mappings that invoke a function, use DeleteEventSourceMapping. For Amazon Web Servicesservices and resources that invoke your function directly, delete the trigger in the service where you originally configured it. |
| GET | /2015-03-31/functions/{FunctionName}/aliases/{Name} | Returns details about a Lambda function alias. |
| GET | /2015-03-31/event-source-mappings/{UUID} | Returns details about an event source mapping. You can get the identifier of a mapping from the output of ListEventSourceMappings. |
| GET | /2015-03-31/functions/{FunctionName} | Returns information about the function or function version, with a link to download the deployment package that's valid for 10 minutes. If you specify a function version, only details that are specific to that version are returned. |
| GET | /2015-03-31/functions/{FunctionName}/configuration | Returns the version-specific settings of a Lambda function or version. The output includes only options that can vary between versions of a function. To modify these settings, use UpdateFunctionConfiguration. To get all of a function's details, including function-level settings, use GetFunction. |
| GET | /2015-03-31/functions/{FunctionName}/policy | Returns the resource-based IAM policy for a function, version, or alias. |
| POST | /2015-03-31/functions/{FunctionName}/invocations | 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 fu
