You can call [any Web API method](https://api.slack.com/methods) using the [`WebClient`](https://slack.dev/python-slack-sdk/basic_usage.html) provided to your Bolt app as `app.client` (given that your app has the appropriate scopes). When you call one the client’s methods, it returns a `SlackResponse` which contains the response from Slack.
The token used to initialize Bolt can be found in the context object, which is required to call most Web API methods.
