Salesforce Slack-Dev-201 Online Access

Slack app-level tokens use the `xapp-` prefix. Unlike bot tokens, app-level tokens represent an application independently of an individual bot installation and are limited to specific application-level API capabilities. Socket Mode is a major use case. To establish Socket Mode, Slack requires an app-level token with the `connections:write` scope. That credential is supplied to `apps.connections.open`, which generates the temporary WebSocket URL through which Slack delivers Events API and interactive payloads. Slack's Socket Mode documentation also demonstrates storing this credential as `SLACK_APP_TOKEN` with a value beginning `xapp-`. By contrast, `xoxb-` identifies bot tokens and `xoxp-` identifies user tokens. `bearer-` is not a Slack token-prefix classification. Therefore, B is the verified answer.

Bolt provides a higher-level application framework that uses Slack's language SDKs underneath. Slack's platform overview explains that the Bolt frameworks for Python, JavaScript, and Java use the corresponding Slack SDKs to handle lower-level development details. The SDK layer exposes primitives such as Web API clients, authentication, HTTP requests, and API method implementations, while Bolt adds listener registration, middleware, context injection, interaction acknowledgment, event routing, and other application-development conveniences. This architecture allows developers to build Slack applications without repeatedly implementing platform plumbing themselves. Bolt and the SDKs therefore are not unrelated, nor do the SDKs automatically replace Bolt. Conversely, Bolt depends on the capabilities supplied by its underlying language ecosystem rather than functioning independently of them. Option B most accurately describes the documented architectural relationship between these components.

Workflow Builder is intentionally designed as a no-code automation environment, so ordinary workspace members can create workflows without being software developers. Slack currently states that, by default, all regular members can access Workflow Builder and create workflows, although owners and administrators can restrict who has permission to do so. In Enterprise organizations, Org Owners and Org Admins can similarly establish organization-level policies governing workflow creation. Workflow Builder therefore enables business users to automate routine processes using triggers, forms, Slack actions, connector steps, and other visual components. It is not restricted to Slack employees, certified developers, or Enterprise Grid owners. The important qualification in option B is “with the appropriate permissions,” because administrative policies can narrow the default access. Therefore, B is the correct answer.

The Events API enables Slack applications to react to activities occurring within Slack. An application subscribes to specific event types, and Slack delivers corresponding event payloads when those activities occur. Examples include messages being posted, reactions being added, members joining channels, files being created, and application mentions. The events available to an application are constrained by its OAuth scopes and the conversations or resources it is authorized to access. Slack can deliver Events API payloads through a public HTTP Request URL or through Socket Mode. After receiving an event, the application typically acknowledges delivery and asynchronously performs any associated business logic, such as calling `chat.postMessage`. The Events API does not manage billing, construct Block Kit layouts, or configure OAuth permissions. Therefore, B correctly describes its primary function.
