# Work with Requests

The following are Apex classes for working with Slack actions.

## RequestContext Class

Describes the context in which a particular Slack action is invoked.

**Usage**

`RequestContext` exposes information about the source of the action in Slack, performs custom logic, and obtains the correct Slack client to respond to Slack based on the request. Each action type receives different information in its `RequestContext`.

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

See [Shortcuts and Slash Commands](/docs/platform/salesforce-slack-sdk/guide/actions_interact.md).
