            'ClientToken' => 'test_1',
            'Description' => 'test scheduler',
            'FlexibleTimeWindow' => [ 
                'Mode' => 'OFF',
            ],
            'Name' => 'test_scheduler', 
            'ScheduleExpression' => 'at(2023-04-05T08:00:00)', 
            'State' => 'ENABLED',
            'Target' => [ 
                'Arn' => 'Arn name copied from aws console for api destination',
                'RoleArn' => 'role arn copied from aws console',

The solution is as below

`
```
$result = $AwsSchedulerClient->createSchedule([
                'ClientToken' => 'test_2',
                'Description' => 'test scheduler',
                'FlexibleTimeWindow' => [ 
                    'Mode' => 'OFF',
                ],
                'Name' => 'test_scheduler2', 
                'ScheduleExpression' => 'at(2023-04-12T08:00:00)', // REQUIRED
                'State' => 'ENABLED',
                'Target' => [ 
                    'Arn' => 'arn:aws:scheduler:::aws-sdk:eventbridge:createApiDestination', //need to add this service name not the arn name of api destination
                    'RoleArn' => '',
                    'Input' => json_encode([
                        'ConnectionArn' => '', 
                        'Description' => 'schedulerAPIs2',
                        'HttpMethod' => 'POST', 
                        'InvocationEndpoint' => 'endpoint url', 
                        'InvocationRateLimitPerSecond' => 10,
                        'Name' => 'schedulerAPIs3', 
                    ]),
                ],
            ]);
```

Answer

> 'Arn' => 'Arn name copied from aws console for api destination',

Would it be possible to share the relevant API ARN?  
For example, an ARN that stops RDS would be the following.  
```
arn:aws:scheduler:::aws-sdk:rds:stopDBInstance
```
