## ChatPostMessageRequest Class

Sends a request to post a message to a channel.

**Usage**

See Slack’s [chat.postMessage method](https://api.slack.com/methods/chat.postMessage).

In this example, the `PostMessage` action runs when a user enters your slash command. The `ViewReference` gets the `selection` view to display a select menu. When the value on the select menu changes, it calls an Apex `slackHomeViewSelectChanged` action that's specified on its onchange `definition` key. Finally, the `apphome` view is published with the selected value.

```java
public class PostMessage extends Slack.SlashCommandDispatcher {

    public override Slack.ActionHandler invoke(Slack.SlashCommandParameters parameters, Slack.RequestContext context) {
        return Slack.ActionHandler.ack(new Handler(parameters, context));
    }

    public class Handler implements Slack.RunnableHandler {
        Slack.SlashCommandParameters parameters;
        Slack.RequestContext context;

        public Handler(Slack.SlashCommandParameters parameters, Slack.RequestContext context){
            this.parameters = parameters;
            this.context = context;
        }

        public void run () {
            Slack.App app = Slack.App.MySlackApp.get();
            Slack.BotClient client = app.getBotClientForTeam(context.getTeamId());
            Slack.ViewReference viewReference = Slack.View.selection.get();
            String channel = context.getChannelId();

            Slack.ChatPostMessageRequest req = new Slack.ChatPostMessageRequest.builder()
                .channel(channel)
                .viewReference(viewReference)
                .build();

        Slack.ChatPostMessageResponse response = client.chatPostMessage(req);
        if (response.getError() != null) {
            System.debug(response.getError());
        } else {
            System.debug('success');
        }
      }
    }
}
```

The `selection` view looks like this.

```yaml
description: "Notifier Message"
components:
  - definition: message
    properties:
      title: "Notifier"
    components:
      - definition: input
        name: "input_block"
        properties:
          label: "Select an option"
        components:
          - definition: select
            properties:
              name: "select_options"
              value: "option_1"
              placeholder: "Please select an option."
              options:
                - identifier: "option_1"
                  label: "Option 1"
                - identifier: "option_2"
                  label: "Option 2"
            events:
              onchange:
                definition: "apex__action__slackHomeViewSelectChanged"
```

Changing the value on the select menu calls the `slackHomeViewSelectChanged` Apex action, which extends [ActionDispatcher](/docs/platform/salesforce-slack-sdk/guide/apex_ref_dispatchers.md#actiondispatcher-class).

```java
public class slackHomeViewSelectChanged extends Slack.ActionDispatcher {

      public override Slack.ActionHandler invoke(Map<String, Object> parameters, Slack.RequestContext context) {
        return Slack.ActionHandler.ack(new Handler(parameters, context));
    }

    public class Handler implements Slack.RunnableHandler {

        Map<String, Object> parameters;
        Slack.RequestContext context;

        public Handler (Map<String, Object> parameters, Slack.RequestContext context){
            this.parameters = parameters;
            this.context = context;
        }

        public void run () {
            Slack.App app = Slack.App.MySlackApp.get();
            Slack.BotClient botClient = app.getBotClientForTeam(context.getTeamId());
            Slack.ViewReference viewReference = Slack.View.apphome.get();

            Slack.ActionPayload actionPayload = context.getActionPayload();
            if (actionPayload != null) {
                String name = actionPayload.getName();
                if (name == 'select_options') {
                    Object value = actionPayload.getValue();
                    viewReference.setParameter('selected', value.toString());
                }
            }

            Slack.HomeView homeView = new Slack.HomeView.builder()
                .viewReference(viewReference)
                .build();

            Slack.ViewsPublishRequest req = new Slack.ViewsPublishRequest.builder()
                .userId(context.getUserId())
                .view(homeView)
                .build();

            Slack.ViewsPublishResponse response = botClient.viewsPublish(req);

            if (response.getError() != null) {
                System.debug(response.getError());
            }
        }
    }
}
```

The `apphome` view looks like this.

```yaml
description: "Home page"
schema:
  properties:
    selected:
      type: string
      defaultValue: "no option has been selected"
components:
  - definition: home
    properties:
      title: "Sample Home"
    components:
      - definition: section
        properties:
          text: "This is the App Home page!!!"
      - definition: section
        properties:
          text: "Selected: {!view.properties.selected}"
```

:::note
Consider using `chat:write` scope on the user token only in response to an inciting user action and inform users that a message will be posted on their behalf. See [Sending messages as other entities](https://api.slack.com/methods/chat.postMessage#authorship).
