Lambda client

This page contains examples with the Lambda client. See the client introduction for a more detailed description how to use a client. You may also want to consider the authentication documentation to understand the many ways you can authenticate with AWS.

The Lambda package could be installed with Composer.

composer require async-aws/lambda

A new client object may be instantiated by:

use AsyncAws\Lambda\LambdaClient;

$lambda = new LambdaClient();

The authentication parameters is read from the environment by default. You can also specify a AWS access id and secret:

use AsyncAws\Lambda\LambdaClient;

$lambda = new LambdaClient([
    'accessKeyId' => 'my_access_key',
    'accessKeySecret' => 'my_access_secret',
    'region' => 'eu-central-1',
]);

For all available options, see the configuration reference.

Usage¶

Invoke a function¶

use AsyncAws\Lambda\LambdaClient;

$lambda = new LambdaClient();

// Find the value for FunctionName here:
// https://console.aws.amazon.com/lambda/home?region=us-east-1#/functions
$result = $lambda->invoke([
    'FunctionName' => 'app-dev-hello_world',
    'Payload' => '{"name": "async-aws/lambda"}',
]);

echo $result->getPayload();
