# Code examples for API Gateway Management API using AWS SDKs
<a name="apigatewaymanagementapi_code_examples"></a>

The following code examples show you how to use Amazon API Gateway Management API with an AWS software development kit (SDK).

*Actions* are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios.

# Use `PostToConnection` with an AWS SDK or CLI
<a name="apigatewaymanagementapi_example_apigatewaymanagementapi_PostToConnection_section"></a>

The following code examples show how to use `PostToConnection`.

------
#### [ CLI ]

**AWS CLI**  
**To send data to a WebSocket connection**  
The following `post-to-connection` example sends a message to a client that's connected to the specified WebSocket API.  

```
aws apigatewaymanagementapi post-to-connection \
    --connection-id L0SM9cOFvHcCIhw= \
    --data "Hello from API Gateway!" \
    --endpoint-url https://aabbccddee.execute-api.us-west-2.amazonaws.com/prod
```
This command produces no output.  
For more information, see [Use @connections commands in your backend service](https://docs.aws.amazon.com/apigateway/latest/developerguide/apigateway-how-to-call-websocket-api-connections.html) in the *Amazon API Gateway Developer Guide*.  
+  For API details, see [PostToConnection](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/apigatewaymanagementapi/post-to-connection.html) in *AWS CLI Command Reference*.

#### [ Rust ]

**SDK for Rust**  
 There's more on GitHub. Find the complete example and learn how to set up and run in the [AWS Code Examples Repository](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/rustv1/examples/apigatewaymanagement#code-examples). 

```
async fn send_data(
    client: &aws_sdk_apigatewaymanagement::Client,
    con_id: &str,
    data: &str,
) -> Result<(), aws_sdk_apigatewaymanagement::Error> {
    client
        .post_to_connection()
        .connection_id(con_id)
        .data(Blob::new(data))
        .send()
        .await?;

    Ok(())
}

    let endpoint_url = format!(
        "https://{api_id}.execute-api.{region}.amazonaws.com/{stage}",
        api_id = api_id,
        region = region,
        stage = stage
    );

    let shared_config = aws_config::from_env().region(region_provider).load().await;
    let api_management_config = config::Builder::from(&shared_config)
        .endpoint_url(endpoint_url)
        .build();
    let client = Client::from_conf(api_management_config);
```
